我试图写一个包装周围的api我的公司正在开发。它是restful的，使用Postman我可以发送一个post请求到像http://subdomain.dev.myapi.com/api/v1/auth/这样的端点，并将用户名和密码作为post数据，并返回一个令牌。一切都按预期工作。现在，当我尝试从PHP做同样的事情时，我得到了一个GuzzleHttp\Psr7\Response对象，但似乎不能在它内部的任何地方找到令牌，因为我与Postman请求。

相关代码如下:

$client = new Client(['base_uri' => 'http://companysub.dev.myapi.com/']);
$response = $client->post('api/v1/auth/', [
    'form_params' => [
        'username' => $user,
        'password' => $password
    ]
]);

var_dump($response); //or $resonse->getBody(), etc...

上面代码的输出看起来像这样(警告，输入的文本墙):

object(guzzlehttp\psr7\response)#36 (6) {

    ["custommetadata":"guzzlehttp\psr7\stream":private]=>

  }
}

Postman的输出是这样的:

{
    "data" : {
        "token" "fasdfasf-asfasdfasdf-sfasfasf"
    }
}

很明显，我忽略了在Guzzle中处理响应对象的一些内容。Guzzle响应指示请求上的状态码为200，因此我不确定究竟需要做什么来检索返回的数据。
