Catching Exceptions from Guzzle

Catching exceptions from Guzzle

If the Exception is being thrown in that try block then at worst case scenario Exception should be catching anything uncaught.

Consider that the first part of the test is throwing the Exception and wrap that in the try block as well.

Catch Guzzle Exception and return string

Try to use exception hierarchy to catch any exception. ClientException only catches status code between 400x-499. To catch other exception or catch within the same Exception you can use RequestException.

public static function get_list($list_id)
    {
        $lists = self::get_lists();
        $params = [
            'list.fields' => 'created_at,follower_count,member_count,private,description,owner_id',
            'user.fields' => 'created_at,description,entities,id,location,name,pinned_tweet_id,profile_image_url,protected,public_metrics,url,username,verified,withheld'
        ];
        try {
            $list = $lists->get($list_id, $params);
            if($list->getStatusCode() == 200)){
                $return_list = json_decode($list->getBody(),true);
            }
        } catch (\GuzzleHttp\Exception\ClientException $e) {
            $error['error'] = $e->getMessage();
            $error['request'] = $e->getRequest();
            if($e->hasResponse()){
              // you can pass a specific status code to catch a particular error here I have catched 400 Bad Request. 
              if ($e->getResponse()->getStatusCode() == '400'){
                 $error['response'] = $e->getResponse(); 
              }
            }
            return $error;
        } catch(\GuzzleHttp\Exception\RequestException $se){
            $error['error'] = $e->getMessage();
            $error['request'] = $e->getRequest();
            return $error;
        } catch(Exception $e){
           //other errors 
        }

        return $list;
    }

Handle Guzzle exception and get HTTP body

Guzzle 3.x

Per the docs, you can catch the appropriate exception type (ClientErrorResponseException for 4xx errors) and call its getResponse() method to get the response object, then call getBody() on that:

use Guzzle\Http\Exception\ClientErrorResponseException;

...

try {
    $response = $request->send();
} catch (ClientErrorResponseException $exception) {
    $responseBody = $exception->getResponse()->getBody(true);
}

Passing true to the getBody function indicates that you want to get the response body as a string. Otherwise you will get it as instance of class Guzzle\Http\EntityBody.

Catch exception from guzzle

you should set the guzzehttp client with option 'http_errors' => false,
the example code should be like this, document:guzzlehttp client http-error option explain

Set to false to disable throwing exceptions on an HTTP protocol errors (i.e., 4xx and 5xx responses). Exceptions are thrown by default when HTTP protocol errors are encountered.

$client->request('GET', '/status/500');
// Throws a GuzzleHttp\Exception\ServerException

$res = $client->request('GET', '/status/500', ['http_errors' => false]);
echo $res->getStatusCode();
// 500





$this->client = new Client([
    'cookies' => true,
    'headers' => $header_params,
    'base_uri' => $this->base_url,
    'http_errors' => false
]);

$response = $this->client->request('GET', '/');
if ($code = $response->getStatusCode() == 200) {
   try {
       // do danger dom things in here
   }catch (/Exception $e){
      //catch
   }

}

Catch Guzzle exceptions on connections refused

Having tried your code, it seems to be throwing an instance of GuzzleHttp\Exception\ConnectException, so change the catch to

} catch (ConnectException $e) {
    $response['status'] = 'Connect Exception';
    $response['message'] = $e->getMessage();
}

( Adding the appropriate use statement...

use GuzzleHttp\Exception\ConnectException;

)

Also noticed that it doesn't have $e->getResponse()->getStatusCode(), which is why I've just set it to a fixed string.

Guzzle: Can't catch exception details

The exception should be an instance of BadResponseException which has a getResponse method. You can then cast the response body to a string.

$response = json_decode($ex->getResponse()->getBody()->getContents(), true);
