Guzzle 6.x和捕获异常/ PHP

[英]Guzzle 6.x and catching exceptions / PHP

我正在输入一个宁静的博客API。 API中提供了简单的错误检查功能。 如果entry_name或entry_body少于8个字符,则其响应如下:

{
  "status":"failure",
 "message":{
        "entry_name":"The entry_name field must be at least 8 characters in length.",
        "entry_body": The entry_body field must be at least 8 characters in length." 
        }
}

在我的网页上,我得到以下信息:

Type: GuzzleHttp\Exception\ClientException

Message: Client error: `PUT https://www.example.com/api/v1/Blog/blog`   
resulted in a `400 Bad Request` response: {"status":"failure","message":
{"entry_name":"The entry_name field must be at least 8 characters in 
length.","entry_body" (truncated...)

我不明白如何在像上面那样抛出错误之前抓到异常。

我想测试失败,如果失败,我想显示消息。

这是我必须捕获异常的代码:

这是我的代码:

         try {
              $response = $client->request('PUT', $theUrl);
              $theBody = $response->getBody();
        } catch (RequestException $e) {
            echo $e;
        }   

但它驶过上述街区:-(

如果您根本不希望Guzzle 6抛出4xx和5xx的异常,则需要创建一个没有http_errors中间件的处理程序堆栈,默认情况下会将其添加到堆栈中:

$handlerStack = new \GuzzleHttp\HandlerStack(\GuzzleHttp\choose_handler());

$handlerStack->push(\GuzzleHttp\Middleware::redirect(), 'allow_redirects');
$handlerStack->push(\GuzzleHttp\Middleware::cookies(), 'cookies');
$handlerStack->push(\GuzzleHttp\Middleware::prepareBody(), 'prepare_body');

$config = ['handler' => $handlerStack]);

$client = new \GuzzleHttp\Client($config);
