README
HTTP client written in PHP on top of ReactPHP.
Table of Contents
Usage
The client is responsible to send HTTP requests and receive the HTTP response from the server.
This library uses PSR-7 objects to make it easier to handle the HTTP-Messsages.
$uri = 'tcp://httpbin.org:80'; $request = new Request('GET', 'http://httpbin.org'); $promise = $client->request($uri, $request);
It could take some time until the response is transferred from the server
to the client.
For this reason the request
-method will return a
ReactPHP promise.
The promise will result in a PSR-7 response object
$promise = $client->request($uri, $request); $promise->then( function (\Psr\Http\Message\ResponseInterface $response) { echo 'Successfully received a response from the server:' . PHP_EOL; echo RingCentral\Psr7\str($response); }, function (\Exception $exception) { echo $exception->getMessage() . PHP_EOL; } );
The body of the response will always be an asynchronous ReactPHP Stream.
$promise = $client->request($uri, $request); $promise->then( function (ResponseInterface $response) { echo 'Successfully received a response from the server:' . PHP_EOL; echo RingCentral\Psr7\str($response); $body = $response->getBody(); $body->on('data', function ($data) { echo "Body-Data: " . $data . PHP_EOL; }); $body->on('end', function () { exit(0); }); }, function (\Exception $exception) { echo $exception->getMessage() . PHP_EOL; } );
The end
-Event will be emmitted when the complete body of the HTTP response
has been transferred to the client.
In the example above it will exit the current script.
Request body
You can add also add a ReactPHP Stream as
the request body to stream data with it.
The body will always be transferred chunked encoded if you use this method,
any header like Content-Length
or other Transfer-Encoding
headers will
be replaced.
$stream = new ReadableStream(); $timer = $loop->addPeriodicTimer(0.5, function () use ($stream) { $stream->emit('data', array(microtime(true) . PHP_EOL)); }); $loop->addTimer(5, function() use ($loop, $timer, $stream) { $loop->cancelTimer($timer); $stream->emit('end'); }); $request = new Request( 'POST', 'http://127.0.0.1:10000', array( 'Host' => '127.0.0.1', 'Content-Type' => 'text/plain' ), $stream ); $promise = $client->request($uri, $request);
This example will transfer every 0.5 seconds a chunked encoded data to the server. The transmission of the body will end after 5 seconds.
