Catch exception from guzzle

Question

I'm using laravel and I have setup the abstract class method to get response from the various APIs I'm calling. But if the API url is unreachable then it throws an exception. I know I'm missing something. Any help would be great for me.

$offers = [];
    try {
      $appUrl = parse_url($this->apiUrl);

      // Call Api using Guzzle
      $client = new Client('' . $appUrl['scheme'] . '://' . $appUrl['host'] . '' . $appUrl['path']);

      if ($appUrl['scheme'] == 'https') //If https then disable ssl certificate
        $client->setDefaultOption('verify', false);

      $request = $client->get('?' . $appUrl['query']);
      $response = $request->send();
      if ($response->getStatusCode() == 200) {
        $offers = json_decode($response->getBody(), true);
      }
    } catch (ClientErrorResponseException $e) {
      Log::info("Client error :" . $e->getResponse()->getBody(true));
    } catch (ServerErrorResponseException $e) {
      Log::info("Server error" . $e->getResponse()->getBody(true));
    } catch (BadResponseException $e) {
      Log::info("BadResponse error" . $e->getResponse()->getBody(true));
    } catch (\Exception $e) {
      Log::info("Err" . $e->getMessage());
    }

    return $offers;

Answer 1

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
   }

}

These exceptions are not defined in guzzle officially.

These Exceptions are defined in AWS SDK for PHP.

For official Guzzle you may just do following.

use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;
use GuzzleHttp\Exception\ClientException;

....
    try {
        $response = $this->client->request($method, $url, [
            'headers'     => $headers,
            'form_params' => $form_parameters,
        ]);
        $body = (string)$response->getBody();
    } catch (ClientException $e) {
        // Do some thing here...
    } catch (RequestException $e) {
        // Do some thing here...
    } catch (\Exception $e) {
        // Do some thing here...
    }
