Not getting expected response from Guzzle

Question

I'm trying to build an endpoint that forwards the data passed to it to an API using the Slim PHP Framework and I'm having trouble getting my response from a Guzzle request.

$app->map( '/api_call/:method', function( $method ) use( $app ){
    $client = new GuzzleHttp\Client([
        'base_url' => $app->config( 'api_base_url' ),
        'defaults' => [
            'query'   => [ 'access_token' => 'foo' ],
        ]
    ]);

    $request = $client->createRequest( $app->request->getMethod(), $method, [
        'query' => $app->request->params()
    ]);

    var_dump( $client->send( $request )->getBody() );

})->via( 'GET', 'POST', 'PUT', 'PATCH', 'DELETE' )->conditions( [ 'route' => '.+?' ] );`

This then gives me...

object(GuzzleHttp\Stream\Stream)[59]
  private 'stream' => resource(72, stream)
  private 'size' => null
  private 'seekable' => boolean true
  private 'readable' => boolean true
  private 'writable' => boolean true
  private 'meta' => 
    array (size=6)
     'wrapper_type' => string 'PHP' (length=3)
      'stream_type' => string 'TEMP' (length=4)
      'mode' => string 'w+b' (length=3)
      'unread_bytes' => int 0
      'seekable' => boolean true
      'uri' => string 'php://temp' (length=10)

...instead of the response of 'cool' I was expecting.

If I just var_dump $client->sendRequest( $request ) I get a 200 OK, and the url is what I expect, http://localhost:8000/test?access_token=foo.

I have another request, but only using $client->post(...) and it works fine without giving me the stream thing back.

I've tried reading the stream using the example at the bottom (http://guzzle.readthedocs.org/en/latest/http-client/response.html) but it's telling me feof doesn't exist.

Anyone have any idea what I'm missing or doing wrong here?

Could be;

$response = $client->send($request)->getBody()->getContents();
$response = $client->send($request)->getBody()->read(1024*100000);

This also work as a shorthand;

$response = ''. $client->send($request)->getBody();
$response = (string) $client->send($request)->getBody();
