How to handle redirects based on status codes in AngularJS $http requests

My angular application includes numerous $http requests, and I am looking for a way to automatically redirect users to the login page in case the server session expires (resulting in a 401 error). Does anyone have a solution that can handle this for all $http calls without having to add .error() to each one individually?

Answer №1

To improve the efficiency of your code, consider implementing an http interceptor that handles all 401 errors by redirecting them.

// Implementing an http interceptor in app.config
app.config(function($$httpProvider) {
    $httpProvider.interceptors.push('my401Interceptor');
});

// Defining the logic for the interceptor
app.factory('my401Interceptor', function($location, $q) {
    return {
        responseError: function(response) {
            if (response.status === 401) {
                 $location.path('/login');
                 return $q.reject(response);
            } else {
                return $q.reject(response);
            }
        }
    };
});

To accomplish this task, you can utilize Interceptors in your code. This snippet is extracted from the Mean.js source code.

angular.module('users').config(['$httpProvider',
function($httpProvider) {
    // Implementing the "not authorized" interceptor for httpProvider
    $httpProvider.interceptors.push(['$q', '$location', 'Authentication',
        function($q, $location, Authentication) {
            return {
                responseError: function(rejection) {
                    switch (rejection.status) {
                        case 401:
                            // Reset the global user authentication
                            Authentication.user = null;

                            // Redirect to the signin page
                            $location.path('signin');
                            break;
                        case 403:
                            // Add logic for unauthorized access behavior 
                            break;
                    }

                    return $q.reject(rejection);
                }
            };
        }
    ]);

 ]);
