Handle exceptions from API

[tousignantf]

Hello,

I have a problem handling 400 response from API.

My problem is that I need to show a particular message when an admin tries to create a new user with an already used email.

The API returns this when it happens:

Response status code: 400
Response body: - Toggle response

{
    "@context": "\/contexts\/ConstraintViolationList",
    "@type": "ConstraintViolationList",
    "hydra:title": "An error occurred",
    "hydra:description": "email: This value is already used.",
    "violations": [
        {
            "propertyPath": "email",
            "message": "This value is already used."
        }
    ]
}

In my controller however, if I Try/Catch the call to the repository, I only have access to the ClientException (thrown in Mapado\RestClientSdk\RestClient::post), so I can't distinguish the particular "dupplicate email" error from other ones, even if the API sent the information in it's 400 response.

Please help, Merci beaucoup

The only solution I think of is to access the response in your catch:

try {
    // do something that will fail
} catch (Mapado\RestClientSdk\Exception\RestClientException $e) {
    $response = $e->getResponse(); // $response should be a Psr\Http\Message\ResponseInterface
    $body = $response->getBody();
    $content = json_decode($body, true);
    var_dump($content['hydra:description']); // should dump ""email: This value is already used."
}

Does this suits your needs ?

Allright, that works!

Thanks a lot! Merci :-)
