Navigating to the requested page after successfully logging in can be

After successfully authenticating a user with JWT authentication, I am attempting to redirect them to a different page. However, I have encountered an error stating that $state.go is not a function when trying to use $location or $window for redirection. As a newcomer to Angular, I believe there must be a way to achieve the redirect using a service in Angular, although I am still learning about factories and services.

In my state.js file, I have set up my state provider as follows:

myApp.config(function ($stateProvider, $urlRouterProvider) {

    // default route
    $urlRouterProvider.otherwise("/Home");
    var header = {
        templateUrl: 'commonViews/Header.html',
        controller: function ($scope) {
        }

    };
    var footer = {
        templateUrl: 'commonViews/Footer.html',
        controller: function ($scope) {
        }
    };
    // ui router states
$stateProvider
    .state('Home', {
        url: "/Home",
        views: {
            header: header,
            content: {
                templateUrl: 'views/HomePage.html',
                controller: function ($scope) {
                }
            },
            footer: footer
        }
    })
    .state('LoggedIn', {
        url: "/LoggedIn",
        views: {
            'header': header,
            'content': {
                templateUrl: 'views/LoggedIn.html',
                controller: function () {
                }
            },
            'footer': footer
        }
    });
});

Additionally, in loginController.js:

myApp.controller('loginController', ['$scope', '$http', 'jwtHelper', '$localStorage', '$state', function ($scope, $http, jwtHelper, $localStorage, $sessionStorage, $state)
{
$scope.email = "";
$scope.password = "";
$scope.token = "";

$scope.loginForm = function () {

    var data = {email: $scope.email, password: $scope.password};
    var url = 'rs/loginResource/login';
    $http.post(url, data).then(function (response)
    {
        $localStorage.token = response.data.token;
        console.log("Encoded Token in localstorage is:" + $localStorage.token);

        if ($localStorage.token) {
         // $location.url("/LoggedIn");
            $state.go('/LoggedIn');
        }

    }, function (error)
    {
        console.log("error", error);
    });
};
}]);

Furthermore, I need to implement refresh token functionality based on expiration time. Would it be beneficial to separate these functions by utilizing a service for sign up and sign in processes?

Answer №1

The issue lies in how you have defined your controller and how you are managing your injections. Contrary to what you may believe, the problem is not simply the "order" in which the injections are made. It's a more serious issue.

myApp.controller('loginController', ['$scope', '$http', 'jwtHelper', '$localStorage', '$state', function ($scope, $http, jwtHelper, $localStorage, $sessionStorage, $state)

In the code snippet above, you are associating '$scope' with a variable named $scope, mapping '$http' to $http, matching 'jwtHelper' with jwtHelper, linking '$localStorage' to $localStorage, assigning '$state' to $sessionStorage, and failing to map anything to $state. This leads to errors when attempting to use a method on an undefined $state variable. In essence, you are injecting 5 dependencies but assigning variables to 6 dependencies, resulting in dysfunctionality.

Answer №2

If you want to redirect in Angular, try using the $window service:

$window.location.href = '/home.html';

Answer №3

In order to correctly utilize the $state.go function, it is important to understand that it accepts the view name and not the URL. To rectify this issue, simply substitute the string '/LoggedIn' with Logged and your code should function properly.

Answer №4

Instead of using $window and location, try incorporating $state.go.
Make sure to include the $state injector in your controller
Implement the following code snippet: $state.go('LoggedIn');
Avoid using $state.go('/LoggedIn');

Remember to use the state name ('LoggedIn') instead of the URL ('/LoggedIn').

With any luck, this solution should work for your specific scenario.

Answer №5

If you are utilizing $window in your controller, remember to include it as a dependency.

myApp.controller('loginController', ['$scope', '$http', 'jwtHelper', '$localStorage', '$state','$window', function ($scope, $http, jwtHelper, $localStorage, $sessionStorage, $state,$window)
{
$window.location.href = '/index.html';
}

Alternatively, if you need to adjust the route without using $window, make sure to also inject $state.

  myApp.controller('loginController', ['$scope', '$http', 'jwtHelper', '$localStorage', '$state','$window','$state', function ($scope, $http, jwtHelper, $localStorage, $sessionStorage, $state,$window,$state)
{
      $state.go('LoggedIn');
}
