Successful HTTP request with an error

Here is a snippet of code I am working with:

$http(request)
    .success(function(data){                                            
                ...
            })
    .error(function(data){
                ...
            });

An ongoing issue I am facing is when the response contains an error. The JSON response shows the error message under data.error, but currently, the way my code is set up, even when there's an error, it registers as successful instead.

What would be the most effective approach to address this? Could simply adding an if statement like below resolve the problem?

if (data.error){ ....

Answer №1

The Angular documentation states that when a response status code falls between 200 and 299, it is considered a successful status. In such cases, the success callback will be triggered. However, if the response is a redirect, XMLHttpRequest will automatically follow it, causing the error callback to not be invoked.

Therefore, if your JSON data includes an `error` property but the HTTP status code is 200, your `.error` handler will not be executed.

In conclusion, using something like `if (data.error) {...}` should suffice in handling this scenario effectively.

Answer №2

It is important to note that using .success and .error is no longer recommended (refer to https://docs.angularjs.org/api/ng/service/$http#deprecation-notice)

Instead, you should utilize the following approach:

$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // This function will be executed asynchronously
    // once the response is received
  }, function errorCallback(response) {
    // Executed asynchronously in case of an error
    // or if the server responds with an error status
  });

I hope this solution proves helpful!
