Post not working in file_get_contents client

[ChristianRiesen]

I wanted to do a simple test. Send out a post to another location. It calls a file that is simply doing a print_r on $_POST.

$browser = new Buzz\Browser();
$response = $browser->post('http://test', array(), array('id' => 123, 'name' => 'tester'));

echo $response;

Returns
HTTP/1.1 200 OK
Date: Sat, 29 Sep 2012 03:48:57 GMT
Server: Apache
X-Powered-By: PHP/5.3.10-1ubuntu3.2
Vary: Accept-Encoding
Content-Length: 10
Connection: close
Content-Type: text/html

Array
(
)

$browser = new Buzz\Browser(new Buzz\Client\Curl());
$response = $browser->post('http://test', array(), array('id' => 123, 'name' => 'tester'));

echo $response;

Returns

HTTP/1.1 200 OK
Date: Sat, 29 Sep 2012 04:07:01 GMT

Array
(
[id] => 123
[name] => tester
)

The inconsistency is in the handling of the request content on post. I can see curl is handling this with a switch, but there is no equivalent on file_get_contents. Is this a limitation of file_get_contents itself I'm unaware of or simply not fully implemented?

I haven't dug on the code but I think this discussion may be helpful How to post data in PHP using file_get_contents?

If we check the code:

public function post($url, $headers = array(), $content = '')
{
    return $this->call($url, RequestInterface::METHOD_POST, $headers, $content);
}

/**
 * Sends a request.
 *
 * @param string $url     The URL to call
 * @param string $method  The request method to use
 * @param array  $headers An array of request headers
 * @param string $content The request content
 *
 * @return MessageInterface The response object
 */
public function call($url, $method, $headers = array(), $content = '')
{
    // ...
}

We'll see that Browser::post() expects string and not array. Can this be the cause of the problem?

P.S. It seems that also only Curl client supports getFields() in the request object. And thus Browser::submit() will fail as well with any bundled client except Curl.

Posting an array of data is not possible with the file_get_contents adapter because the stream context does not support it only curl does. To fix it, you need to convert it to an url encoded format with the http_build_query method.

@kriswallsmith What about converting it when it is passed to stream_context_create in case it is an array? It should fix the issue mentionned by @denisvmedia about the Browser::submit method.

Closing this since it is super old.
