Catching Guzzle exceptions
I'm trying to catch exceptions in a set of tests running on an API I'm developing, and I'm using Guzzle to consume API methods. I have wrapped the test in a try/catch block but it still throws an unhandled exception error. Adding an event listener as described in their documentation doesn't seem to do anything. I need to be able to retrieve responses with HTTP codes 500, 401, 400, in fact any response that is not 200, because if that doesn't work the system will set the most appropriate code based on the result of the call.
Current code example
foreach($tests as $test){
$client = new Client($api_url);
$client->getEventDispatcher()->addLi stener('request.error', function(Event $event) {
if ($event['response']->getStatusCode() == 401) {
$newResponse = new Response($event['response']->getStatusCode());
$event['response'] = $newResponse;
$event->stopPropagation();
}
});
try {
$client->setDefaultOption('query', $query_string);
$request = $client->get($api_version . $test['method'], array(), isset($test['query'])?$test['query']:array());
// Do something with Guzzle.
$response = $request->send();
displayTest($request, $response);
}
catch (GuzzleHttpExceptionClientErrorResponseException $e) {
$req = $e->getRequest();
$resp =$e->getResponse();
displayTest($req,$resp);
}
catch (GuzzleHttpExceptionServerErrorResponseException $e) {
$req = $e->getRequest();
$resp =$e->getResponse();
displayTest($req,$resp);
}
catch (GuzzleHttpExceptionBadResponseException $e) {
$req = $e->getRequest();
$resp =$e->getResponse();
displayTest($req,$resp);
}
catch( Exception $e){
echo "AGH!";
}
unset($client);
$client=null;
}
Even with a specific catch block that throws the exception type, I still get a return
Fatal error: Uncaught exception 'GuzzleHttpExceptionClientErrorResponseException' with message 'Client error response [status code] 401 [reason phrase] Unauthorized [url]
As you might expect, all execution on the page stops. Adding the BadResponseException catch allows me to catch 404 correctly, but this doesn't seem to work with 500 or 401 responses. Can anyone suggest where I am going wrong.
