public function testGetClientsAction()
{
    $client = static::createClient();

    $cookie = new Cookie('locale2','en',time() + 3600 * 24 * 7,'/',null,false,false);
    $client->getCookieJar()->set($cookie);

    // Visit user login page and login
    $crawler = $client->request('GET','/login');
    $form = $crawler->selectButton('login')->form();
    $crawler = $client->submit($form,array('_username' => 'greg','_password' => 'greg'));

    $client->request(
       'GET','/clients',array(),array('X-Requested-With' => 'XMLHttpRequest','accept' => 'application/json')
    );

    print_r($client->getResponse());
    die();

}

在正在测试的方法中,我在第一行：

print_r($request->headers->all());
