Replacing the $http.get function in AngularJS

Here is the code snippet I am currently working with:

$http.get(url).success(function(response,status,header,config) {
    $scope.mymodel = response;
}

I need to verify the http status and trigger a function accordingly. Modifying all 100 instances of http.get calls throughout the project seems tedious. Can we skip this by overriding the success function like so?

function success(response,status,header,config) {
    if(status!=200){
       //my stuff
    }
    super.success(response,status,header,config);
}

Alternatively, can we replace $http.get(url).success with $http.get(url).success2 to inform my colleagues that henceforth they should use $http.get(url).success2 as it is better!

Update

Even though I am aware that this function is deprecated, I am obliged to use it due to project specifications.

Answer №1

To achieve this, utilize the $httpProvider.interceptors method.

You have the ability to monitor the $http request and response in order to perform any desired actions and then return the $q unchanged.

$httpProvider.interceptors.push(['$q', 'customErrorHandler', function($q, customErrorHandler) {
                        return {

                            requestError: function(rejection){                            
                                customErrorHandler.handleAnyError(rejection);    
                                return $q.reject(rejection);
                            },

                            responseError: function(rejection){                            
                                customErrorHandler.handleAnyError(rejection);
                                return $q.reject(rejection);
                            }
                        };
    }]);

In the provided code snippet, I call the handleAnyError function from the factory mathScriptLoadError to examine the rejection object and trigger a specific process based on certain values. This operation does not interfere with the $http.get function in any way.

Answer №2

Notice of Deprecated Features

The once popular promise methods success and error in $http have now been phased out. It is recommended to switch over to using the standard then method instead. If

$httpProvider.useLegacyPromiseExtensions
is set to false, calling these methods will result in a $http/legacy error.

-- AngularJS $http Service API Reference -- Deprecation Notice

Spread the word:

"From now on, use $http.get(url).then for smoother operations!"

Within the AngularJS framework, there are three designated spots for incorporating response interceptor functions.

It is possible to globally, locally, or by class, intercept XHR responses and make modifications as needed.
