php - 调用未定义的方法 GuzzleHttp\Psr7\Response::isSuccessful()

Question

所以我根据TeamUp calendar documentation安装了Guzzle库版本6 .但是，当我尝试运行下面的代码时，我得到

Fatal error: Call to undefined method GuzzleHttp\Psr7\Response::isSuccessful()  

代码:

<?php
include 'vendor/autoload.php';

define('API_KEY','****ww9d5ea2b0540ba1e02c08100b0e5**');

$client = new GuzzleHttp\Client(['headers' => ['Teamup-Token' => API_KEY]]);
$res = $client->get('https://api.teamup.com/ks************/events?startDate=2016-08-21&endDate=2016-08-25');

if ($res->isSuccessful()) {
    echo $res->getBody();
    // {"event":{ ... }}
}

不应该包含在图书馆中吗？
任何人？

Answer 1

是的，没有方法isSuccessful .
默认情况下，如果服务器返回错误，Guzzle 将抛出异常

http://docs.guzzlephp.org/en/latest/quickstart.html

A GuzzleHttp\Exception\ServerException is thrown for 500 level errors if the http_errors request option is set to true.

A GuzzleHttp\Exception\ClientException is thrown for 400 level errors if the http_errors request option is set to true.

In the event of a networking error (connection timeout, DNS errors, etc.), a GuzzleHttp\Exception\RequestException is thrown.

无论如何，您可以使用检查响应的状态代码

$res->getStatusCode();
