By contrast, our General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. The +General Public License applies to the Free Software Foundation's +software and to any other program whose authors commit to using it. +You can use it for your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Specifically, the General Public License is designed to make +sure that you have the freedom to give away or sell copies of free +software, that you receive source code or can get it if you want it, +that you can change the software or use pieces of it in new free +programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of a such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must tell them their rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any program or other work which +contains a notice placed by the copyright holder saying it may be +distributed under the terms of this General Public License. The +"Program", below, refers to any such program or work, and a "work based +on the Program" means either the Program or any work containing the +Program or a portion of it, either verbatim or with modifications. Each +licensee is addressed as "you". + + 1. You may copy and distribute verbatim copies of the Program's source +code as you receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice and +disclaimer of warranty; keep intact all the notices that refer to this +General Public License and to the absence of any warranty; and give any +other recipients of the Program a copy of this General Public License +along with the Program. You may charge a fee for the physical act of +transferring a copy. + + 2. You may modify your copy or copies of the Program or any portion of +it, and copy and distribute such modifications under the terms of Paragraph +1 above, provided that you also do the following: + + a) cause the modified files to carry prominent notices stating that + you changed the files and the date of any change; and + + b) cause the whole of any work that you distribute or publish, that + in whole or in part contains the Program or any part thereof, either + with or without modifications, to be licensed at no charge to all + third parties under the terms of this General Public License (except + that you may choose to grant warranty protection to some or all + third parties, at your option). + + c) If the modified program normally reads commands interactively when + run, you must cause it, when started running for such interactive use + in the simplest and most usual way, to print or display an + announcement including an appropriate copyright notice and a notice + that there is no warranty (or else, saying that you provide a + warranty) and that users may redistribute the program under these + conditions, and telling the user how to view a copy of this General + Public License. + + d) You may charge a fee for the physical act of transferring a + copy, and you may at your option offer warranty protection in + exchange for a fee. + +Mere aggregation of another independent work with the Program (or its +derivative) on a volume of a storage or distribution medium does not bring +the other work under the scope of these terms. + + 3. You may copy and distribute the Program (or a portion or derivative of +it, under Paragraph 2) in object code or executable form under the terms of +Paragraphs 1 and 2 above provided that you also do one of the following: + + a) accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of + Paragraphs 1 and 2 above; or, + + b) accompany it with a written offer, valid for at least three + years, to give any third party free (except for a nominal charge + for the cost of distribution) a complete machine-readable copy of the + corresponding source code, to be distributed under the terms of + Paragraphs 1 and 2 above; or, + + c) accompany it with the information you received as to where the + corresponding source code may be obtained. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form alone.) + +Source code for a work means the preferred form of the work for making +modifications to it. For an executable file, complete source code means +all the source code for all modules it contains; but, as a special +exception, it need not include source code for modules which are standard +libraries that accompany the operating system on which the executable +file runs, or for standard header files or definitions files that +accompany that operating system. + + 4. You may not copy, modify, sublicense, distribute or transfer the +Program except as expressly provided under this General Public License. +Any attempt otherwise to copy, modify, sublicense, distribute or transfer +the Program is void, and will automatically terminate your rights to use +the Program under this License. However, parties who have received +copies, or rights to use copies, from you under this General Public +License will not have their licenses terminated so long as such parties +remain in full compliance. + + 5. By copying, distributing or modifying the Program (or any work based +on the Program) you indicate your acceptance of this license to do so, +and all its terms and conditions. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the original +licensor to copy, distribute or modify the Program subject to these +terms and conditions. You may not impose any further restrictions on the +recipients' exercise of the rights granted herein. + + 7. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of the license which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +the license, you may choose any version ever published by the Free Software +Foundation. + + 8. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to humanity, the best way to achieve this is to make it +free software which everyone can redistribute and change under these +terms. + + To do so, attach the following notices to the program. It is safest to +attach them to the start of each source file to most effectively convey +the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 1, or (at your option) + any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19xx name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the +appropriate parts of the General Public License. Of course, the +commands you use may be called something other than `show w' and `show +c'; they could even be mouse-clicks or menu items--whatever suits your +program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

(You will + not be required to justify it to the Copyright Holder, but only to the + computing community at large as a market that must bear the fee.) + - "Freely Available" means that no fee is charged for the item itself, though + there may be fees involved in handling the item. It also means that + recipients of the item may redistribute it under the same conditions they + received it. + +1. You may make and give away verbatim copies of the source form of the +Standard Version of this Package without restriction, provided that you +duplicate all of the original copyright notices and associated disclaimers. + +2. You may apply bug fixes, portability fixes and other modifications derived +from the Public Domain or from the Copyright Holder. A Package modified in such +a way shall still be considered the Standard Version. + +3. You may otherwise modify your copy of this Package in any way, provided that +you insert a prominent notice in each changed file stating how and when you +changed that file, and provided that you do at least ONE of the following: + + a) place your modifications in the Public Domain or otherwise make them + Freely Available, such as by posting said modifications to Usenet or an + equivalent medium, or placing the modifications on a major archive site + such as ftp.uu.net, or by allowing the Copyright Holder to include your + modifications in the Standard Version of the Package. + + b) use the modified Package only within your corporation or organization. + + c) rename any non-standard executables so the names do not conflict with + standard executables, which must also be provided, and provide a separate + manual page for each non-standard executable that clearly documents how it + differs from the Standard Version. + + d) make other distribution arrangements with the Copyright Holder. + +4. You may distribute the programs of this Package in object code or executable +form, provided that you do at least ONE of the following: + + a) distribute a Standard Version of the executables and library files, + together with instructions (in the manual page or equivalent) on where to + get the Standard Version. + + b) accompany the distribution with the machine-readable source of the Package + with your modifications. + + c) accompany any non-standard executables with their corresponding Standard + Version executables, giving the non-standard executables non-standard + names, and clearly documenting the differences in manual pages (or + equivalent), together with instructions on where to get the Standard + Version. + + d) make other distribution arrangements with the Copyright Holder. + +5. You may charge a reasonable copying fee for any distribution of this +Package. You may charge any fee you choose for support of this Package. You +may not charge a fee for this Package itself.

STDERR "Oh no!!\n" }); + +DESCRIPTION + + This module provides a small wrapper for unifying the programming + interfaces of several different actual user agents (HTTP clients) under + one familiar interface. + + Rather than providing yet another programming interface for you to + learn, HTTP::AnyUA follows the HTTP::Tiny interface. This also means + that you can plug in any supported HTTP client (LWP::UserAgent, Furl, + etc.) and use it as if it were HTTP::Tiny. + + There are a lot of great HTTP clients available for Perl, each with + different goals, different feature sets, and of course different + programming interfaces! If you're an end user, you can just pick one of + these clients according to the needs of your project (or personal + preference). But if you're writing a module that needs to interface + with a web server (like perhaps a RESTful API wrapper) and you want + your users to be able to use whatever HTTP client they want, + HTTP::AnyUA can help you support that! + + It's a good idea to let the end user pick whatever HTTP client they + want to use, because they're the one who knows the requirements of + their application or script. If you're writing an event-driven + application, you'll need to use a non-blocking user agent like + Mojo::UserAgent. If you're writing a simple command-line script, you + may decide that your priority is to minimize dependencies and so may + want to go with HTTP::Tiny. + + Unfortunately, many modules on CPAN are hardcoded to work with specific + HTTP clients, leaving the end user unable to use the HTTP client that + would be best for them. Although the end user won't -- or at least + doesn't need to -- use HTTP::AnyUA directly, they will benefit from + client choice if their third-party modules use HTTP::AnyUA or something + like it. + + The primary goal of HTTP::AnyUA is to make it easy for module + developers to write HTTP code once that can work with any HTTP client + the end user may decide to plug in. A secondary goal is to make it easy + for anyone to add support for new or yet-unsupported user agents. + +ATTRIBUTES + + ua + + Get the user agent that was passed to "new". + + response_is_future + + Get and set whether or not responses are Future objects. + + backend + + Get the backend instance. You normally shouldn't need this. + +METHODS + + new + + $any_ua = HTTP::AnyUA->new(ua => $user_agent, %attr); + $any_ua = HTTP::AnyUA->new($user_agent, %attr); + + Construct a new HTTP::AnyUA. + + request + + $response = $any_ua->request($method, $url); + $response = $any_ua->request($method, $url, \%options); + + Make a request, get a response. + + Compare to "request" in HTTP::Tiny. + + get, head, put, post, delete + + $response = $any_ua->get($url); + $response = $any_ua->get($url, \%options); + $response = $any_ua->head($url); + $response = $any_ua->head($url, \%options); + # etc. + + Shortcuts for "request" where the method is the method name rather than + the first argument. + + Compare to "get|head|put|post|delete" in HTTP::Tiny. + + post_form + + $response = $any_ua->post_form($url, $formdata); + $response = $any_ua->post_form($url, $formdata, \%options); + + Does a POST request with the form data encoded and sets the + Content-Type header to application/x-www-form-urlencoded. + + Compare to "post_form" in HTTP::Tiny. + + mirror + + $response = $http->mirror($url, $filepath, \%options); + if ($response->{success}) { + print "$filepath is up to date\n"; + } + + Does a GET request and saves the downloaded document to a file. If the + file already exists, its timestamp will be sent using the + If-Modified-Since request header (which you can override). If the + server responds with a 304 (Not Modified) status, the success field + will be true; this is usually only the case for 2XX statuses. If the + server responds with a Last-Modified header, the file will be updated + to have the same modification timestamp. + + Compare to "mirror" in HTTP::Tiny. This version differs slightly in + that this returns internal exception responses (for cases like being + unable to write the file locally, etc.) rather than actually throwing + the exceptions. The reason for this is that exceptions as responses are + easier to deal with for non-blocking HTTP clients, and the fact that + this method throws exceptions in HTTP::Tiny seems like an inconsistency + in its interface. + + register_backend + + HTTP::AnyUA->register_backend($user_agent_package => $backend_package); + HTTP::AnyUA->register_backend('MyAgent' => 'MyBackend'); # HTTP::AnyUA::Backend::MyBackend + HTTP::AnyUA->register_backend('LWP::UserAgent' => '+SpecialBackend'); # SpecialBackend + + Register a backend for a new user agent type or override a default + backend. Backend packages are relative to the HTTP::AnyUA::Backend:: + namespace unless prefixed with a +. + + If you only need to set a backend as a one-off thing, you could also + pass an instantiated backend to "new". + +SUPPORTED USER AGENTS + + * AnyEvent::HTTP + + * Furl + + * HTTP::AnyUA - a little bit meta, but why not? + + * HTTP::Tiny + + * LWP::UserAgent + + * Mojo::UserAgent + + * Net::Curl::Easy + + Any HTTP client that inherits from one of these in a well-behaved + manner should also be supported. + + Of course, there are many other HTTP clients on CPAN that HTTP::AnyUA + doesn't yet support. I'm more than happy to help add support for + others, so send me a message if you know of an HTTP client that needs + support. See HTTP::AnyUA::Backend for how to write support for a new + HTTP client. + +NON-BLOCKING USER AGENTS + + HTTP::AnyUA tries to target the HTTP::Tiny interface, which is a + blocking interface. This means that when you call "request", it is + supposed to not return until either the response is received or an + error occurs. This doesn't jive well with non-blocking HTTP clients + which expect the flow to reenter an event loop so that the request can + complete concurrently. + + In order to reconcile this, a Future will be returned instead of the + normal hashref response if the wrapped HTTP client is non-blocking + (such as Mojo::UserAgent or AnyEvent::HTTP). This Future object may be + used to set up callbacks that will be called when the request is + completed. You can call "response_is_future" to know if the response is + or will be a Future. + + This is typically okay for the end user; since they're the one who + chose which HTTP client to use in the first place, they should know + whether they should expect a Future or a direct response when they make + an HTTP request, but it does add some burden on you as a module writer + because if you ever need to examine the response, you may need to write + code like this: + + my $resp = $any_ua->get('http://www.perl.org/'); + + if ($any_ua->response_is_future) { + $resp->on_done(sub { + my $real_resp = shift; + handle_response($real_resp); + }); + } + else { + handle_response($resp); # response is the real response already + } + + This actually isn't too annoying to deal with in practice, but you can + avoid it if you like by forcing the response to always be a Future. + Just set the "response_is_future" attribute. Then you don't need to do + an if-else because the response will always be the same type: + + $any_ua->response_is_future(1); + + my $resp = $any_ua->get('http://www.perl.org/'); + + $resp->on_done(sub { # response is always a Future + my $real_resp = shift; + handle_response($real_resp); + }); + + Note that this doesn't make a blocking HTTP client magically + non-blocking. The call to "request" will still block if the client is + blocking, and your "done" callback will simply be fired immediately. + But this does let you write the same code in your module and have it + work regardless of whether the underlying HTTP client is blocking or + non-blocking. + + The default behavior is to return a direct hashref response if the HTTP + client is blocking and a Future if the client is non-blocking. It's up + to you to decide whether or not to set response_is_future, and you + should also consider whether you want to expose the possibility of + either type of response or always returning Future objects to the end + user of your module. It doesn't matter for users who choose + non-blocking HTTP clients because they will be using Future objects + either way, but users who know they are using a blocking HTTP client + may appreciate not having to deal with Future objects at all. + +FREQUENTLY ASKED QUESTIONS + + How do I set up proxying, SSL, cookies, timeout, etc.? + + HTTP::AnyUA provides a common interface for using HTTP clients, not for + instantiating or configuring them. Proxying, SSL, and other custom + settings can be configured directly through the underlying HTTP client; + see the documentation for your particular user agent to learn how to + configure these things. + + AnyEvent::HTTP is a bit of a special case because there is no + instantiated object representing the client. For this particular user + agent, you can configure the backend to pass a default set of options + whenever it calls http_request. See "options" in + HTTP::AnyUA::Backend::AnyEvent::HTTP: + + $any_ua->backend->options({recurse => 5, timeout => 15}); + + If you are a module writer, you should probably receive a user agent + from your end user and leave this type of configuration up to them. + + Why use HTTP::AnyUA instead of some other HTTP client? + + Maybe you shouldn't. If you're an end user writing a script or + application, you can just pick the HTTP client that suits you best and + use it. For example, if you're writing a Mojolicious app, you're not + going wrong by using Mojo::UserAgent; it's loaded with features and is + well-integrated with that particular environment. + + As an end user, you could wrap the HTTP client you pick in an + HTTP::AnyUA object, but the only reason to do this is if you prefer + using the HTTP::Tiny interface. + + The real benefit of HTTP::AnyUA (or something like it) is if module + writers use it to allow end users of their modules to be able to plug + in whatever HTTP client they want. For example, a module that + implements an API wrapper that has a hard dependency on LWP::UserAgent + or even HTTP::Tiny is essentially useless for non-blocking + applications. If the same hypothetical module had been written using + HTTP::AnyUA then it would be useful in any scenario. + + Why use the HTTP::Tiny interface? + + The HTTP::Tiny interface is simple but provides all the essential + functionality needed for a capable HTTP client and little more. That + makes it easy to provide an implementation for, and it also makes it + straightforward for module authors to use. + + Marrying the HTTP::Tiny interface with Future gives us these benefits + for both blocking and non-blocking modules and applications. + +SPECIFICATION + + This section specifies a standard set of data structures that can be + used to make a request and get a response from a user agent. This is + the specification HTTP::AnyUA uses for its programming interface. It is + heavily based on HTTP::Tiny's interface, and parts of this + specification were adapted or copied verbatim from that module's + documentation. The intent is for this specification to be written such + that HTTP::Tiny is already a compliant implementor of the specification + (at least as of the specification's publication date). + + The Request + + A request is a tuple of the form (Method, URL) or (Method, URL, + Options). + + Method + + Method MUST be a string representing the HTTP verb. This is commonly + "GET", "POST", "HEAD", "DELETE", etc. + + URL + + URL MUST be a string representing the remote resource to be acted upon. + The URL MUST have unsafe characters escaped and international domain + names encoded before being passed to the user agent. A user agent MUST + generated a "Host" header based on the URL in accordance with RFC 2616; + a user agent MAY throw an error if a "Host" header is given with the + "headers". + + Options + + Options, if present, MUST be a hash reference containing zero or more + of the following keys with appropriate values. A user agent MAY support + more options than are specified here. + + headers + + The value for the headers key MUST be a hash reference containing zero + or more HTTP header names (as keys) and header values. The value for a + header MUST be either a string containing the header value OR an array + reference where each item is a string. If the value for a header is an + array reference, the user agent MUST output the header multiple times + with each value in the array. + + User agents MAY may add headers, but SHOULD NOT replace user-specified + headers unless otherwise documented. + + content + + The value for the content key MUST be a string OR a code reference. If + the value is a string, its contents will be included with the request + as the body. If the value is a code reference, the referenced code will + be called iteratively to produce the body of the request, and the code + MUST return an empty string or undef value to indicate the end of the + request body. If the value is a code reference, a user agent SHOULD use + chunked transfer encoding if it supports it, otherwise a user agent MAY + completely drain the code of content before sending the request. + + data_callback + + The value for the data_callback key MUST be a code reference that will + be called zero or more times, once for each "chunk" of response body + received. A user agent MAY send the entire response body in one call. + The referenced code MUST be given two arguments; the first is a string + containing a chunk of the response body, the second is an in-progress + response. + + The Response + + A response MUST be a hash reference containg some required keys and + values. A response MAY contain some optional keys and values. + + success + + A response MUST include a success key, the value of which is a boolean + indicating whether or not the request is to be considered a success + (true is a success). Unless otherwise documented, a successful result + means that the operation returned a 2XX status code. + + url + + A response MUST include a url key, the value of which is the URL that + provided the response. This is the URL used in the request unless there + were redirections, in which case it is the last URL queried in a + rediretion chain. + + status + + A response MUST include a status key, the value of which is the HTTP + status code of the response. If an internal exception occurs (e.g. + connection error), then the status code MUST be 599. + + reason + + A response MUST include a reason key, the value of which is the + response phrase returned by the server OR "Internal Exception" if an + internal exception occurred. + + content + + A response MAY include a content key, the value of which is the + response body returned by the server OR the text of the exception if an + internal exception occurred. This field MUST be missing or empty if the + server provided no response OR if the body was already provided via + "data_callback". + + headers + + A response SHOULD include a headers key, the value of which is a hash + reference containing zero or more HTTP header names (as keys) and + header values. Keys MUST be lowercased. The value for a header MUST be + either a string containing the header value OR an array reference where + each item is the value of one of the repeated headers. + + redirects + + A response MAY include a redirects key, the value of which is an array + reference of one or more responses from redirections that occurred to + fulfill the current request, in chronological order. + +ENVIRONMENT + + * PERL_HTTP_ANYUA_DEBUG - If 1, print some info useful for debugging + to STDERR. + +CAVEATS + + Not all HTTP clients implement the same features or in the same ways. + While the point of HTTP::AnyUA is to hide those differences, you may + notice some (hopefully) insignificant differences when plugging in + different clients. For example, LWP::UserAgent sets some headers on the + response such as client-date and client-peer that won't appear when + using other clients. Little differences like these probably aren't big + deal. Other differences may be a bigger deal, depending on what's + important to you. For example, some clients (like HTTP::Tiny) may do + chunked transfer encoding in situations where other clients won't + (probably because they don't support it). It's not a goal of this + project to eliminate all of the differences, but if you come across a + difference that is significant enough that you think you need to detect + the user agent and write special logic, I would like to learn about + your use case. + +SEE ALSO + + These modules share similar goals or provide overlapping functionality: + + * Future::HTTP + + * HTTP::Any + + * HTTP::Tinyish + + * Plient + +BUGS + + Please report any bugs or feature requests on the bugtracker website + https://github.com/chazmcgarvey/HTTP-AnyUA/issues + + When submitting a bug or request, please include a test-file or a patch + to an existing test-file that illustrates the bug or desired feature. + +AUTHOR + + Charles McGarvey + +COPYRIGHT AND LICENSE + + This software is copyright (c) 2017 by Charles McGarvey. + + This is free software; you can redistribute it and/or modify it under + the same terms as the Perl 5 programming language system itself. + diff --git a/lib/HTTP/AnyUA.pm b/lib/HTTP/AnyUA.pm new file mode 100644 index 0000000..6d44018 --- /dev/null +++ b/lib/HTTP/AnyUA.pm @@ -0,0 +1,796 @@ +package HTTP::AnyUA; +# ABSTRACT: An HTTP user agent programming interface unification layer + + +use 5.010; +use warnings; +use strict; + +our $VERSION = '0.900'; # VERSION + +use HTTP::AnyUA::Util; +use Module::Loader; +use Scalar::Util; + + +our $BACKEND_NAMESPACE; +our @BACKENDS; +our %REGISTERED_BACKENDS; + +BEGIN { + $BACKEND_NAMESPACE = __PACKAGE__ .

This also means that you can plug in any supported HTTP client +(L, L, etc.) and use it as if it were L. + +There are a lot of great HTTP clients available for Perl, each with different goals, different +feature sets, and of course different programming interfaces! If you're an end user, you can just +pick one of these clients according to the needs of your project (or personal preference). But if +you're writing a module that needs to interface with a web server (like perhaps a RESTful API +wrapper) and you want your users to be able to use whatever HTTP client they want, HTTP::AnyUA can +help you support that! + +It's a good idea to let the end user pick whatever HTTP client they want to use, because they're the +one who knows the requirements of their application or script. If you're writing an event-driven +application, you'll need to use a non-blocking user agent like L. If you're writing +a simple command-line script, you may decide that your priority is to minimize dependencies and so +may want to go with L. + +Unfortunately, many modules on CPAN are hardcoded to work with specific HTTP clients, leaving the +end user unable to use the HTTP client that would be best for them. Although the end user won't -- +or at least doesn't need to -- use HTTP::AnyUA directly, they will benefit from client choice if +their third-party modules use HTTP::AnyUA or something like it. + +The primary goal of HTTP::AnyUA is to make it easy for module developers to write HTTP code once +that can work with any HTTP client the end user may decide to plug in. A secondary goal is to make +it easy for anyone to add support for new or yet-unsupported user agents. + +=head1 ATTRIBUTES + +=head2 ua + +Get the user agent that was passed to L. + +=head2 response_is_future + +Get and set whether or not responses are L objects. + +=head2 backend + +Get the backend instance.

If the file already exists, its +timestamp will be sent using the C request header (which you can override). If +the server responds with a C<304> (Not Modified) status, the C field will be true; this is +usually only the case for C<2XX> statuses. If the server responds with a C header, +the file will be updated to have the same modification timestamp. + +Compare to L. This version differs slightly in that this returns internal +exception responses (for cases like being unable to write the file locally, etc.) rather than +actually throwing the exceptions. The reason for this is that exceptions as responses are easier to +deal with for non-blocking HTTP clients, and the fact that this method throws exceptions in +L seems like an inconsistency in its interface. + +=head2 register_backend + + HTTP::AnyUA->register_backend($user_agent_package => $backend_package); + HTTP::AnyUA->register_backend('MyAgent' => 'MyBackend'); # HTTP::AnyUA::Backend::MyBackend + HTTP::AnyUA->register_backend('LWP::UserAgent' => '+SpecialBackend'); # SpecialBackend + +Register a backend for a new user agent type or override a default backend. Backend packages are +relative to the C namespace unless prefixed with a C<+>. + +If you only need to set a backend as a one-off thing, you could also pass an instantiated backend to +L. + +=head1 SUPPORTED USER AGENTS + +=over 4 + +=item * + +L + +=item * + +L + +=item * + +L - a little bit meta, but why not? + +=item * + +L + +=item * + +L + +=item * + +L + +=item * + +L + +=back + +Any HTTP client that inherits from one of these in a well-behaved manner should also be supported. + +Of course, there are many other HTTP clients on CPAN that HTTP::AnyUA doesn't yet support. I'm more +than happy to help add support for others, so send me a message if you know of an HTTP client that +needs support. See L for how to write support for a new HTTP client. + +=head1 NON-BLOCKING USER AGENTS + +HTTP::AnyUA tries to target the L interface, which is a blocking interface. This means +that when you call L, it is supposed to not return until either the response is received +or an error occurs. This doesn't jive well with non-blocking HTTP clients which expect the flow to +reenter an event loop so that the request can complete concurrently. + +In order to reconcile this, a L will be returned instead of the normal hashref response if +the wrapped HTTP client is non-blocking (such as L or L). This +L object may be used to set up callbacks that will be called when the request is completed. +You can call L to know if the response is or will be a L. + +This is typically okay for the end user; since they're the one who chose which HTTP client to use in +the first place, they should know whether they should expect a L or a direct response when +they make an HTTP request, but it does add some burden on you as a module writer because if you ever +need to examine the response, you may need to write code like this: + + my $resp = $any_ua->get('http://www.perl.org/'); + + if ($any_ua->response_is_future) { + $resp->on_done(sub { + my $real_resp = shift; + handle_response($real_resp); + }); + } + else { + handle_response($resp); # response is the real response already + } + +This actually isn't too annoying to deal with in practice, but you can avoid it if you like by +forcing the response to always be a L. Just set the L attribute. Then +you don't need to do an if-else because the response will always be the same type: + + $any_ua->response_is_future(1); + + my $resp = $any_ua->get('http://www.perl.org/'); + + $resp->on_done(sub { # response is always a Future + my $real_resp = shift; + handle_response($real_resp); + }); + +Note that this doesn't make a blocking HTTP client magically non-blocking. The call to L +will still block if the client is blocking, and your "done" callback will simply be fired +immediately. But this does let you write the same code in your module and have it work regardless of +whether the underlying HTTP client is blocking or non-blocking. + +The default behavior is to return a direct hashref response if the HTTP client is blocking and +a L if the client is non-blocking. It's up to you to decide whether or not to set +C, and you should also consider whether you want to expose the possibility of +either type of response or always returning L objects to the end user of your module. It +doesn't matter for users who choose non-blocking HTTP clients because they will be using L +objects either way, but users who know they are using a blocking HTTP client may appreciate not +having to deal with L objects at all. + +=head1 FREQUENTLY ASKED QUESTIONS + +=head2 How do I set up proxying, SSL, cookies, timeout, etc.? + +HTTP::AnyUA provides a common interface for I HTTP clients, not for instantiating or +configuring them. Proxying, SSL, and other custom settings can be configured directly through the +underlying HTTP client; see the documentation for your particular user agent to learn how to +configure these things. + +L is a bit of a special case because there is no instantiated object representing +the client. For this particular user agent, you can configure the backend to pass a default set of +options whenever it calls C. See L: + + $any_ua->backend->options({recurse => 5, timeout => 15}); + +If you are a module writer, you should probably receive a user agent from your end user and leave +this type of configuration up to them. + +=head2 Why use HTTP::AnyUA instead of some other HTTP client? + +Maybe you shouldn't. If you're an end user writing a script or application, you can just pick the +HTTP client that suits you best and use it. For example, if you're writing a L app, +you're not going wrong by using L; it's loaded with features and is well-integrated +with that particular environment. + +As an end user, you I wrap the HTTP client you pick in an HTTP::AnyUA object, but the only +reason to do this is if you prefer using the L interface. + +The real benefit of HTTP::AnyUA (or something like it) is if module writers use it to allow end +users of their modules to be able to plug in whatever HTTP client they want. For example, a module +that implements an API wrapper that has a hard dependency on L or even L +is essentially useless for non-blocking applications. If the same hypothetical module had been +written using HTTP::AnyUA then it would be useful in any scenario. + +=head2 Why use the HTTP::Tiny interface? + +The L interface is simple but provides all the essential functionality needed for +a capable HTTP client and little more. That makes it easy to provide an implementation for, and it +also makes it straightforward for module authors to use. + +Marrying the L interface with L gives us these benefits for both blocking and +non-blocking modules and applications. + +=head1 SPECIFICATION + +This section specifies a standard set of data structures that can be used to make a request and get +a response from a user agent. This is the specification HTTP::AnyUA uses for its programming +interface. It is heavily based on L's interface, and parts of this specification were +adapted or copied verbatim from that module's documentation. The intent is for this specification to +be written such that L is already a compliant implementor of the specification (at least +as of the specification's publication date). + +=head2 The Request + +A request is a tuple of the form C<(Method, URL)> or C<(Method, URL, Options)>. + +=head3 Method + +Method B be a string representing the HTTP verb. This is commonly C<"GET">, C<"POST">, +C<"HEAD">, C<"DELETE">, etc. + +=head3 URL + +URL B be a string representing the remote resource to be acted upon. The URL B have +unsafe characters escaped and international domain names encoded before being passed to the user +agent. A user agent B generated a C<"Host"> header based on the URL in accordance with RFC +2616; a user agent B throw an error if a C<"Host"> header is given with the L. + +=head3 Options + +Options, if present, B be a hash reference containing zero or more of the following keys with +appropriate values. A user agent B support more options than are specified here. + +=head4 headers + +The value for the C key B be a hash reference containing zero or more HTTP header +names (as keys) and header values. The value for a header B be either a string containing the +header value OR an array reference where each item is a string. If the value for a header is an +array reference, the user agent B output the header multiple times with each value in the +array. + +User agents B may add headers, but B replace user-specified headers unless +otherwise documented. + +=head4 content + +The value for the C key B be a string OR a code reference. If the value is a string, +its contents will be included with the request as the body. If the value is a code reference, the +referenced code will be called iteratively to produce the body of the request, and the code B +return an empty string or undef value to indicate the end of the request body. If the value is +a code reference, a user agent B use chunked transfer encoding if it supports it, otherwise +a user agent B completely drain the code of content before sending the request. + +=head4 data_callback + +The value for the C key B be a code reference that will be called zero or more +times, once for each "chunk" of response body received. A user agent B send the entire response +body in one call. The referenced code B be given two arguments; the first is a string +containing a chunk of the response body, the second is an in-progress L. + +=head2 The Response + +A response B be a hash reference containg some required keys and values. A response B +contain some optional keys and values. + +=head3 success + +A response B include a C key, the value of which is a boolean indicating whether or +not the request is to be considered a success (true is a success). Unless otherwise documented, +a successful result means that the operation returned a 2XX status code. + +=head3 url + +A response B include a C key, the value of which is the URL that provided the response. +This is the URL used in the request unless there were redirections, in which case it is the last URL +queried in a rediretion chain. + +=head3 status + +A response B include a C key, the value of which is the HTTP status code of the +response. If an internal exception occurs (e.g. connection error), then the status code B be +C<599>. + +=head3 reason + +A response B include a C key, the value of which is the response phrase returned by +the server OR "Internal Exception" if an internal exception occurred. + +=head3 content + +A response B include a C key, the value of which is the response body returned by the +server OR the text of the exception if an internal exception occurred. This field B be missing +or empty if the server provided no response OR if the body was already provided via +L. + +=head3 headers + +A response B include a C key, the value of which is a hash reference containing +zero or more HTTP header names (as keys) and header values. Keys B be lowercased. The value +for a header B be either a string containing the header value OR an array reference where each +item is the value of one of the repeated headers. + +=head3 redirects + +A response B include a C key, the value of which is an array reference of one or +more responses from redirections that occurred to fulfill the current request, in chronological +order. + +=head1 ENVIRONMENT + +=over 4 + +=item * + +C - If 1, print some info useful for debugging to C. + +=back + +=head1 CAVEATS + +Not all HTTP clients implement the same features or in the same ways. While the point of HTTP::AnyUA +is to hide those differences, you may notice some (hopefully) I differences when +plugging in different clients. For example, L sets some headers on the response such +as C and C that won't appear when using other clients. Little differences +like these probably aren't big deal. Other differences may be a bigger deal, depending on what's +important to you. For example, some clients (like L) may do chunked transfer encoding in +situations where other clients won't (probably because they don't support it).
