Question

以下代码是我的service.js.如何在我的令牌过期且未经授权时注销？我们需要设置本地存储吗？有人可以帮助我或建议我如何才能达到我想要的结果。谢谢你提前

'use strict';

angular.module('Authentication')

.factory('AuthenticationService', ['Base64', '$http', '$cookieStore', '$rootScope', '$timeout',

                .then(function (response) {
                    callback(response);
                });

        };

        service.SetCredentials = function (username, password) {
            var authdata = Base64.encode(username + ':' + password);

.factory('Base64', function () {


    var keyStr = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=';

    return {
        encode: function (input) {
            var output = "";
            var chr1, chr2, chr3 = "";
            var enc1, enc2, enc3, enc4 = "";
            var i = 0;

            do {

                chr2 = input.charCodeAt(i++);
                chr3 = input.charCodeAt(i++);

                enc1 = chr1 >> 2;
                enc2 = ((chr1 & 3) << 4) | (chr2 >> 4);
                enc3 = ((chr2 & 15) << 2) | (chr3 >> 6);
                enc4 = chr3 & 63;

                if (isNaN(chr2)) {
                    enc3 = enc4 = 64;
                } else if (isNaN(chr3)) {
                    enc4 = 64;
                }

                output = output +
                    keyStr.charAt(enc1) +
                    keyStr.charAt(enc2) +

                chr1 = chr2 = chr3 = "";
                enc1 = enc2 = enc3 = enc4 = "";
            } while (i < input.length);

            return output;
        },

        decode: function (input) {
            var output = "";
            var chr1, chr2, chr3 = "";
            var enc1, enc2, enc3, enc4 = "";
            var i = 0;

            // remove all characters that are not A-Z, a-z, 0-9, +, /, or =

                output = output + String.fromCharCode(chr1);

                if (enc3 != 64) {
                    output = output + String.fromCharCode(chr2);
                }
                if (enc4 != 64) {
                    output = output + String.fromCharCode(chr3);

                enc1 = enc2 = enc3 = enc4 = "";

            } while (i < input.length);

            return output;
        }
    };

});

这是我的Auth控制器.js

'use strict';

 angular.module('Authentication')
.controller('LoginController', ['$scope', '$rootScope', '$location', 
'AuthenticationService', 'TokenService', '$http',
function ($scope, $rootScope, 
$location,AuthenticationService,TokenService,$http) {
    // login status
    AuthenticationService.ClearCredentials();
    $scope.login = function () {
        $scope.dataLoading = true;
        AuthenticationService.SetCredentials($scope.username, $scope.password);
        AuthenticationService.Login(function (response) {
            if (response.data.success) {

               TokenService.SetToken(response.data.token);
                $http.post('http://117d8128.ngrok.io/api/users')
                .then(function(response){
                   console.log(response);
                     $location.path('/');
                });


            } else {
                $scope.error = response.message;
                $scope.dataLoading = false;
            }
        });
    };
}]);

以下是我的家庭控制器。这里当令牌是unauth它应该注销。但它没有注销。有人帮助我吗？

  'use strict';

  angular.module('Home')

  .controller('HomeController',
['$scope',
function ($scope,$http) {
    $http.post('http://117d8128.ngrok.io/api/users')
                .then(function(response){
                   console.log(response);
                     $location.path('/');
                });

}]);

主控制器

    'use strict';

   //  modules
    angular.module('Authentication', []);
   angular.module('Home', []);

 angular.module('HttpAuth', [
'Authentication',
'Home',
'ngRoute',
'ngCookies'
 ])

 .config(['$routeProvider', function ($routeProvider) {

$routeProvider
    .when('/login', {
        controller: 'LoginController',
        templateUrl: 'modules/authentication/views/login.html'
    })

    .when('/', {
        controller: 'HomeController',
        templateUrl: 'modules/home/views/home.html'
    })

    .otherwise({ redirectTo: '/login' });
}])

 .run(['$rootScope', '$location', '$cookieStore', '$http',
function ($rootScope, $location, $cookieStore, $http) {
    // keep user logged in after page refreshed
    $rootScope.globals = $cookieStore.get('globals') || {};
    if ($rootScope.globals.currentUser) {
        $http.defaults.headers.common['Authorization'] = 'Basic ' + 
$rootScope.globals.currentUser.authdata; 
    }

    $rootScope.$on('$locationChangeStart', function (event, next, current) {
        // redirect to login page if not logged in
        if ($location.path() !== '/login' && !$rootScope.globals.currentUser) {
            $location.path('/login');
        }
    });
}]);

用户成功登录后，您可以在localStorage中存储令牌。

  //Storing token in local Storage
    service.setToken(token){
    $window.localStorage.setItem('token', token);
}

在主控制器上，每次请求都可以检查令牌是否存在/过期。

//Getting token from local Storage
service.getToken(token){
return $window.localStorage.getItem(token);
}
if(service.getToken()){
  //Proceed in the application
}else{
 //logout & redirect to homepage/login page
}

这是它的主旨，你可以根据你的要求修改上面的代码。
