[Reference here][psr-http]. +* This means that `setHeaders()` does not wipe out every existing header + anymore. +* We also support multiple headers with the same name. +* Use `Request::getHeaderAsArray()` and `Response::getHeaderAsArray()` to + get a hold off multiple headers with the same name. +* If you use `getHeader()`, and there's more than 1 header with that name, we + concatenate all these with a comma. +* `addHeader()` will now preserve an existing header with that name, and add a + second header with the same name. +* The message class should be a lot faster now for looking up headers. No more + array traversal, because we maintain a tiny index. +* Added: `URLUtil::resolve()` to make resolving relative urls super easy. +* Switched to PSR-4. +* #12: Circumventing CURL's FOLLOW_LOCATION and doing it in PHP instead. This + fixes compatibility issues with people that have open_basedir turned on. +* Added: Content negotiation now correctly support mime-type parameters such as + charset. +* Changed: `Util::negotiate()` is now deprecated. Use + `Util::negotiateContentType()` instead. +* #14: The client now only follows http and https urls. + + +2.0.4 (2014-07-14) +------------------ + +* Changed: No longer escaping @ in urls when it's not needed. +* Fixed: #7: Client now correctly deals with responses without a body. + + +2.0.3 (2014-04-17) +------------------ + +* Now works on hhvm! +* Fixed: Now throwing an error when a Request object is being created with + arguments that were valid for sabre/http 1.0.

This is now handled by + Sapi::getRequest. + + +2.0.0alpha6 (2014-01-03) +------------------------ + +* Added: Asynchronous HTTP client. See examples/asyncclient.php. +* Fixed: Issue #4: Don't escape colon (:) when it's not needed. +* Fixed: Fixed a bug in the content negotation script. +* Fixed: Fallback for when CURLOPT_POSTREDIR is not defined (mainly for hhvm). +* Added: The Request and Response object now have a `__toString()` method that + serializes the objects into a standard HTTP message. This is mainly for + debugging purposes. +* Changed: Added Response::getStatusText(). This method returns the + human-readable HTTP status message. This part has been removed from + Response::getStatus(), which now always returns just the status code as an + int. +* Changed: Response::send() is now Sapi::sendResponse($response). +* Changed: Request::createFromPHPRequest is now Sapi::getRequest(). +* Changed: Message::getBodyAsStream and Message::getBodyAsString were added. The + existing Message::getBody changed its behavior, so be careful. + + +2.0.0alpha5 (2013-11-07) +------------------------ + +* Added: HTTP Status 451 Unavailable For Legal Reasons. Fight government + censorship! +* Added: Ability to catch and retry http requests in the client when a curl + error occurs. +* Changed: Request::getPath does not return the query part of the url, so + everything after the ? is stripped. +* Added: a reverse proxy example. + + +2.0.0alpha4 (2013-08-07) +------------------------ + +* Fixed: Doing a GET request with the client uses the last used HTTP method + instead. +* Added: HttpException +* Added: The Client class can now automatically emit exceptions when HTTP errors + occurred. + + +2.0.0alpha3 (2013-07-24) +------------------------ + +* Changed: Now depends on sabre/event package. +* Changed: setHeaders() now overwrites any existing http headers. +* Added: getQueryParameters to RequestInterface. +* Added: Util::negotiate. +* Added: RequestDecorator, ResponseDecorator. +* Added: A very simple HTTP client. +* Added: addHeaders() to append a list of new headers. +* Fixed: Not erroring on unknown HTTP status codes. +* Fixed: Throwing exceptions on invalid HTTP status codes (not 3 digits). +* Fixed: Much better README.md +* Changed: getBody() now uses a bitfield to specify what type to return. + + +2.0.0alpha2 (2013-07-02) +------------------------ + +* Added: Digest & AWS Authentication. +* Added: Message::getHttpVersion and Message::setHttpVersion. +* Added: Request::setRawServerArray, getRawServerValue. +* Added: Request::createFromPHPRequest +* Added: Response::send +* Added: Request::getQueryParameters +* Added: Utility for dealing with HTTP dates. +* Added: Request::setPostData and Request::getPostData. +* Added: Request::setAbsoluteUrl and Request::getAbsoluteUrl. +* Added: URLUtil, methods for calculation relative and base urls. +* Removed: Response::sendBody + + +2.0.0alpha1 (2012-10-07) +------------------------ + +* Fixed: Lots of small naming improvements +* Added: Introduction of Message, MessageInterface, Response, ResponseInterface. + +Before 2.0.0, this package was built-into SabreDAV, where it first appeared in +January 2009. + +[psr-http]: https://github.com/php-fig/fig-standards/blob/master/proposed/http-message.md +[rfc7240]: http://tools.ietf.org/html/rfc7240 +[rfc7617]: https://tools.ietf.org/html/rfc7617 diff --git a/lib/vendor/sabre/http/LICENSE b/lib/vendor/sabre/http/LICENSE new file mode 100644 index 0000000..864041b --- /dev/null +++ b/lib/vendor/sabre/http/LICENSE @@ -0,0 +1,27 @@ +Copyright (C) 2009-2017 fruux GmbH (https://fruux.com/) + +All rights reserved. + +Redistribution and use in source and binary forms, with or without modification, +are permitted provided that the following conditions are met: + + * Redistributions of source code must retain the above copyright notice, + this list of conditions and the following disclaimer. + * Redistributions in binary form must reproduce the above copyright notice, + this list of conditions and the following disclaimer in the documentation + and/or other materials provided with the distribution. + * Neither the name Sabre nor the names of its contributors + may be used to endorse or promote products derived from this software + without specific prior written permission. + + THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" + AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE + IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE + ARE DISCLAIMED.

This library is +effectively a wrapper around the following PHP constructs: + +For Input: + +* `$_GET`, +* `$_POST`, +* `$_SERVER`, +* `php://input` or `$HTTP_RAW_POST_DATA`. + +For output: + +* `php://output` or `echo`, +* `header()`. + +What this library provides, is a `Request` object, and a `Response` object. + +The objects are extendable and easily mockable. + +Build status +------------ + +| branch | status | +|--------|---------------------------------------------------------------------------------------------------------------| +| master | [![Build Status](https://travis-ci.org/sabre-io/http.svg?branch=master)](https://travis-ci.org/sabre-io/http) | +| 4.2 | [![Build Status](https://travis-ci.org/sabre-io/http.svg?branch=4.2)](https://travis-ci.org/sabre-io/http) | +| 3.0 | [![Build Status](https://travis-ci.org/sabre-io/http.svg?branch=3.0)](https://travis-ci.org/sabre-io/http) | + +Installation +------------ + +Make sure you have [composer][1] installed. In your project directory, create, +or edit a `composer.json` file, and make sure it contains something like this: + +```json +{ + "require" : { + "sabre/http" : "~5.0.0" + } +} +``` + +After that, just hit `composer install` and you should be rolling. + +Quick history +------------- + +This library came to existence in 2009, as a part of the [`sabre/dav`][2] +project, which uses it heavily. + +It got split off into a separate library to make it easier to manage +releases and hopefully giving it use outside of the scope of just `sabre/dav`. + +Although completely independently developed, this library has a LOT of +overlap with [Symfony's `HttpFoundation`][3]. + +Said library does a lot more stuff and is significantly more popular, +so if you are looking for something to fulfill this particular requirement, +I'd recommend also considering [`HttpFoundation`][3]. + + +Getting started +--------------- + +First and foremost, this library wraps the superglobals. The easiest way to +instantiate a request object is as follows: + +```php +use Sabre\HTTP; + +include 'vendor/autoload.php'; + +$request = HTTP\Sapi::getRequest(); +``` + +This line should only happen once in your entire application. Everywhere else +you should pass this request object around using dependency injection. + +You should always typehint on its interface: + +```php +function handleRequest(HTTP\RequestInterface $request) { + + // Do something with this request :) + +} +``` + +A response object you can just create as such: + +```php +use Sabre\HTTP; + +include 'vendor/autoload.php'; + +$response = new HTTP\Response(); +$response->setStatus(201); // created ! +$response->setHeader('X-Foo', 'bar'); +$response->setBody( + 'success!' +); + +``` + +After you fully constructed your response, you must call: + +```php +HTTP\Sapi::sendResponse($response); +``` + +This line should generally also appear once in your application (at the very +end). + +Decorators +---------- + +It may be useful to extend the `Request` and `Response` objects in your +application, if you for example would like them to carry a bit more +information about the current request. + +For instance, you may want to add an `isLoggedIn` method to the Request +object. + +Simply extending Request and Response may pose some problems: + +1. You may want to extend the objects with new behaviors differently, in + different subsystems of your application, +2. The `Sapi::getRequest` factory always returns an instance of + `Request` so you would have to override the factory method as well, +3. By controlling the instantiation and depend on specific `Request` and + `Response` instances in your library or application, you make it harder to + work with other applications which also use `sabre/http`. + +In short: it would be bad design. Instead, it's recommended to use the +[decorator pattern][6] to add new behavior where you need it. `sabre/http` +provides helper classes to quickly do this. + +Example: + +```php +use Sabre\HTTP; + +class MyRequest extends HTTP\RequestDecorator { + + function isLoggedIn() { + + return true; + + } + +} +``` + +Our application assumes that the true `Request` object was instantiated +somewhere else, by some other subsystem. This could simply be a call like +`$request = Sapi::getRequest()` at the top of your application, +but could also be somewhere in a unit test. + +All we know in the current subsystem, is that we received a `$request` and +that it implements `Sabre\HTTP\RequestInterface`. To decorate this object, +all we need to do is: + +```php +$request = new MyRequest($request); +``` + +And that's it, we now have an `isLoggedIn` method, without having to mess +with the core instances. + + +Client +------ + +This package also contains a simple wrapper around [cURL][4], which will allow +you to write simple clients, using the `Request` and `Response` objects you're +already familiar with. + +It's by no means a replacement for something like [Guzzle][7], but it provides +a simple and lightweight API for making the occasional API call. + +### Usage + +```php +use Sabre\HTTP; + +$request = new HTTP\Request('GET', 'http://example.org/'); +$request->setHeader('X-Foo', 'Bar'); + +$client = new HTTP\Client(); +$response = $client->send($request); + +echo $response->getBodyAsString(); +``` + +The client emits 3 event using [`sabre/event`][5]. `beforeRequest`, +`afterRequest` and `error`. + +```php +$client = new HTTP\Client(); +$client->on('beforeRequest', function($request) { + + // You could use beforeRequest to for example inject a few extra headers. + // into the Request object. + +}); + +$client->on('afterRequest', function($request, $response) { + + // The afterRequest event could be a good time to do some logging, or + // do some rewriting in the response. + +}); + +$client->on('error', function($request, $response, &$retry, $retryCount) { + + // The error event is triggered for every response with a HTTP code higher + // than 399. + +}); + +$client->on('error:401', function($request, $response, &$retry, $retryCount) { + + // You can also listen for specific error codes. This example shows how + // to inject HTTP authentication headers if a 401 was returned. + + if ($retryCount > 1) { + // We're only going to retry exactly once. + } + + $request->setHeader('Authorization', 'Basic xxxxxxxxxx'); + $retry = true; + +}); +``` + +### Asynchronous requests + +The `Client` also supports doing asynchronous requests. This is especially handy +if you need to perform a number of requests, that are allowed to be executed +in parallel. + +The underlying system for this is simply [cURL's multi request handler][8], +but this provides a much nicer API to handle this. + +Sample usage: + +```php + +use Sabre\HTTP; + +$request = new Request('GET', 'http://localhost/'); +$client = new Client(); + +// Executing 1000 requests +for ($i = 0; $i < 1000; $i++) { + $client->sendAsync( + $request, + function(ResponseInterface $response) { + // Success handler + }, + function($error) { + // Error handler + } + ); +} + +// Wait for all requests to get a result. +$client->wait(); + +``` + +Check out `examples/asyncclient.php` for more information. + +Writing a reverse proxy +----------------------- + +With all these tools combined, it becomes very easy to write a simple reverse +http proxy. + +```php +use + Sabre\HTTP\Sapi, + Sabre\HTTP\Client; + +// The url we're proxying to. +$remoteUrl = 'http://example.org/'; + +// The url we're proxying from. Please note that this must be a relative url, +// and basically acts as the base url. +// +// If your $remoteUrl doesn't end with a slash, this one probably shouldn't +// either. +$myBaseUrl = '/reverseproxy.php'; +// $myBaseUrl = '/~evert/sabre/http/examples/reverseproxy.php/'; + +$request = Sapi::getRequest(); +$request->setBaseUrl($myBaseUrl); + +$subRequest = clone $request; + +// Removing the Host header. +$subRequest->removeHeader('Host'); + +// Rewriting the url. +$subRequest->setUrl($remoteUrl . $request->getPath()); + +$client = new Client(); + +// Sends the HTTP request to the server +$response = $client->send($subRequest); + +// Sends the response back to the client that connected to the proxy. +Sapi::sendResponse($response); +``` + +The Request and Response API's +------------------------------ + +### Request + +```php + +/** + * Creates the request object + * + * @param string $method + * @param string $url + * @param array $headers + * @param resource $body + */ +public function __construct($method = null, $url = null, array $headers = null, $body = null); + +/** + * Returns the current HTTP method + * + * @return string + */ +function getMethod(); + +/** + * Sets the HTTP method + * + * @param string $method + * @return void + */ +function setMethod($method); + +/** + * Returns the request url. + * + * @return string + */ +function getUrl(); + +/** + * Sets the request url. + * + * @param string $url + * @return void + */ +function setUrl($url); + +/** + * Returns the absolute url. + * + * @return string + */ +function getAbsoluteUrl(); + +/** + * Sets the absolute url. + * + * @param string $url + * @return void + */ +function setAbsoluteUrl($url); + +/** + * Returns the current base url. + * + * @return string + */ +function getBaseUrl(); + +/** + * Sets a base url. + * + * This url is used for relative path calculations. + * + * The base url should default to / + * + * @param string $url + * @return void + */ +function setBaseUrl($url); + +/** + * Returns the relative path. + * + * This is being calculated using the base url.
