如果未通过异常进行身份验证,angularjs将重定向到登录页面

编辑：忘了提到我一直在和AngularJs一起工作一周,所以如果你看到一些你认为应该改变的东西并且与问题无关,请随时在评论部分告诉我.

好的,所以我有我的身份验证控制器和提供程序,我不会显示,因为它们与问题的范围无关.
然后我有一个拦截器来检查用户是否在进行呼叫时进行了身份验证.如果是这样的话,我在请求上设置Authentication头以包含用户的令牌,如果不是我将用户重定向到登录页面,甚至不向服务器发出请求(显然如果有人绕过这个,那么它也是API的授权) .

我想要的是添加一些例外,这意味着即使用户没有Auth Token,也有一些我想要允许的页面.如果它是一个特定的路径,我能够这样做,但是我想允许访问我的404页面并且它在我指定的路由中.另外去404页面,我怎样才能使我的拦截器如果不转到此页面,则仅重定向到登录.

拦截器

.factory('authInterceptorService',['$q','$location','localStorageService',function ($q,$location,localStorageService) {

    var authInterceptorServiceFactory = {};

    var authData = localStorageService.get('authorizationData');

    var _request = function (config) {

        config.headers = config.headers || {};

        if (authData) {
            config.headers.Authorization = 'Bearer ' + authData.token;
        } else if ($location.path != '/accounts/login' && $location.path != '/accounts/register') {
            $location.path('/accounts/login');
        }

        return config;
    }

    var _responseError = function (rejection) {
        if (rejection.status === 401) {
            $location.path('/accounts/login');
        }
        return $q.reject(rejection);
    }

    authInterceptorServiceFactory.request = _request;
    authInterceptorServiceFactory.responseError = _responseError;

    return authInterceptorServiceFactory;
}])

在我的路由

$urlRouterProvider.otherwise('/page-not-found');

 $stateProvider
     (...)//rest of the states

     .state('page-not-found',{
         url: '/page-not-found',templateUrl: '/Content/partials/error/404.html',data: {
             displayName: false
         }
     })

     (...)//rest of the states

我试图将’/ page-not-found’添加到我的if但是它不会按预期工作,因为当第一次检查位置时它仍未被重定向.

由charlietfl消化我现在正试图使用??决心,但它甚至没有通过我的功能.

我从拦截器中删除了这段代码：

else if ($location.path != '/accounts/login' && $location.path != '/accounts/register') {
    $location.path('/accounts/login');
}

并向身份验证模块添加新服务：

.service('authCheckService',['$http','$q',function ($http,$q,localStorageService) {
    var self = {
        'onlyLoggedIn': function ($state,$q) {
            var deferred = $q.defer();
            var authData = localStorageService.get('authorizationData');
            console.log(authData);
            if (authData) {
                deferred.resolve();
            } else {
                deferred.reject();
                $state.go('login');
            }
            return deferred.promise;
        }
    }

    return self;
}]);

我试着把它称为：

.state('smo-dashboard',{
        url: '/dashboard',templateUrl: '/Content/partials/dashboard.html',resolve: authCheckServiceProvider.onlyLoggedIn
})

请注意,我正在尝试记录authData var以检查它是否正常工作但它不是,并且控制台上也没有错误.

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

    // function to check the authentication //
    var Auth = ["$q","authService",authService) {
        authService.fillAuthData;
        if (authService.authentication.isAuth) {
            return $q.when(authService.authentication);
        } else {
            return $q.reject({ authenticated: false });
        }
    }];

    /* if the state does not exist */
    $urlRouterProvider
        .otherwise('/page-not-found'); 

    $stateProvider

        // state that allows non authenticated users //
        .state('home',{
            url: '/',templateUrl: '/Content/partials/home.html',})

        // state that needs authentication //
        .state('smo-dashboard',{
            url: '/dashboard',resolve: {
                auth: Auth
            }
        })

        // errors //
         .state('page-not-found',{
             url: '/page-not-found',templateUrl: '/Content/partials/error/404.html'
         })

        // accounts //
        .state('login',{
            url: '/accounts/login',templateUrl: '/Content/partials/account/login.html'
        })

        // OTHER STATES //
    }
);

$scope.$on("$stateChangeError",function (event,toState,toParams,fromState,fromParams,error) {
    $state.go("login");
});
