When the token is different from null my Isauthenticated has to be positive,

app.controller("HomeCtrl", function ($scope, $location) {
    let token = localStorage.getItem("token");
    $scope.user = JSON.parse(token);

    if (token === null) {
        $scope.IsAuthenticated = false;
        $('body').removeClass('nav-md');
        $('body').addClass('login');
        $location.path('/login');
        console.log($scope.IsAuthenticated);
    } else{
        $scope.IsAuthenticated = true;
        $('body').removeClass('login');
        $('body').addClass('nav-md');
        $location.path('/');
        console.log($scope.IsAuthenticated);
    }

    $scope.doLogout = function () {
        localStorage.removeItem('token');
        $scope.IsAuthenticated = false;
        $location.path('/login');
        console.log("chamou aqui");
        location.reload();
    }
});

even when the user logs my Isauthenticated value to false. how do I fix the problem? Below is my Loginctrl code

app.controller("LoginCtrl", function ($scope, LoginAPI, $location) {

    $scope.doLogin = function (model) {
        if (model.username === undefined || model.password === undefined) {
            return false;
        }

        LoginAPI.post(model).success(function (results) {
            localStorage.removeItem('token');
            //Armazena o token no localStorage
            localStorage.setItem('token', JSON.stringify(results));
            //preciso que o meu IsAuthenticated fique true antes de executar o comando abaixo
            $location.path('/');
        })
         .error(function (Error) {
             console.log(Error);
         }
    };
});

  • There may be a problem with the scope declared by let. How about using var instead?

  • put var and did not help

  • The variable token is being created?

  • Yes, I can log in perfectly, I enter the panel. Only as soon as I log in, I want my Authenticated to be positive as soon as I log in. The problem that this happening is that I soon, and I have to update the page once for it to stay true

  • So, use the service to share the same information between controllers, that is, isAuthenticated = true. Change the value of the variable in the service and take this value from the controller HomeCtrl. Edit: you will have to inject the service in HomeCtrl.

In place of $location.path('/'); just put window.location.href = '/home/index'; Because as you are logging in, the first moment the page should be updated and reloaded. By doing this the problem will be solved.

This happens because you are assigning value by Loginctrl, the value has to be passed by Homectrl which by what I understand and your main Scope

  • I tend to agree. It would be better to build in Loginapi service an expression of the kind $scope.isAuthenticated = true and then use a third party to verify that the user is authenticated on each route.

  • This is also an option, do something like a Route Guard, if you have an ngRoute you may be doing the validation whenever you change route in the resolve{}
