Gu 6. 6.x /没有得到预期的结果

Question

我有一个平静的API。当我运行以下网址邮递员，我收到的回应如下：

POSTMAN RUN URL 
DELETE 
https://www.example.com/api/v1/Blog/blog/13 


     { 
     "status":"Failure", 
     "message":"The specified blog post could not be found" 
     } 

以上是当然的预期，但是，我无法读取“状态”和“消息”。我如何得到答复？这是我目前的代码：

 $entry_id = $this->uri->segment(3); 
     $theUrl = $this->config->item('base_url').'api/v1/Blog/blog/'.$entry_id; 
     // tested $theUrl and works 
     $client = new GuzzleHttp\Client([ 
     'base_uri' =>  $theUrl, 
     'timeout' =>  3.0, 
     'http_errors' => FALSE 
     ]); 
     $response = $client->delete($theUrl); 
     $code = $response->getStatusCode(); 
     $response = $client->delete($theUrl); 
     $x = $response->getBody(); 

echo "<pre>"; 
echo var_dump($x); // cannot see message or status anywhere. 
echo "</pre>"; 

您的建议非常感谢。

+++ 现在我已经试过这个修改后的代码，但仍看不到回复的状态或消息日期：

$entry_id = $this->uri->segment(3); 

    $theUrl = $this->config->item('base_url').'api/v1/Blog/blog/'.$entry_id; 
    $client = new GuzzleHttp\Client([ 
     'timeout' =>  3.0, 
     'http_errors' => FALSE 
     ]); 
    $response = $client->delete($theUrl, ['debug' => true]); 
    $code = $response->getStatusCode(); 
    $x = $response->getBody(); 

    echo "<pre>"; 
    echo var_dump($x); 
    echo "</pre>"; 

    die();

Answer 1

我认为新的GuzzleHttp \ Client的base_uri参数是不需要的。 base_uri参数用于设置基本url。 （http://docs.guzzlephp.org/en/latest/quickstart.html?highlight=base_uri）然后，所有对客户端的调用都应该使用相对uris。由于您在删除函数调用中使用绝对URL，因此您不需要base_uri参数。

另外您还调用了两次删除函数：$ response = $ client-> delete（$ theUrl）。

Answer 2

根据docs。 你应该做

$x = $response->getBody()->getContents(); 

或浇铸body到string：

$x = (string)$response->getBody()
