Zend框架卷曲 - 调试GET

How do I view the actual raw GET request?

    $config = array(
        'adapter'   => 'Zend\Http\Client\Adapter\Curl',
        'curloptions' => array(CURLOPT_FOLLOWLOCATION => true),
    );

    $client = new Client($this->uri, $config);

    $client->setParameterGet(array(
        'foo' => 'bar'
    ));        

    $response = $client->send($client->getRequest());

    echo htmlentities($response->getBody()."<br/>"); // The response is as expected. But I need to see the RAW request so I can debug.
    die();

Add:

'curloptions' => array(
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_VERBOSE => 1,
    CURLOPT_STDERR => fopen('/tmp/curl.txt', 'a+'),
),

CURLOPT_VERBOSE enables verbose output to CURLOPT_STDERR, which we specify above as a file.

Typically, you can also use fopen('php://output', 'w') to see debug output on the same stream echo or print use.

See curl_setopt() and CURLOPT_VERBOSE for more info.
