Auth0 - auth.isAuthenticated 不起作用答案

【问题标题】：Auth0 - auth.isAuthenticated not workingAuth0 - auth.isAuthenticated 不起作用
【发布时间】：2016-09-16 09:05:52
【问题描述】：

我试图隐藏导航栏中的按钮，具体取决于用户是否经过身份验证。 Auth0 已启动并正在运行，但我似乎无法在 ng-if 中使用它。

这是我的代码：

NavCtrl.js

/* global myApp*/
myApp.controller('navCtrl', function($scope, auth, store, $location){
    $scope.isActive = function(destination){
        return destination === $location.path();
    }

    $scope.login = function doAuth() {
    auth.signin({
      authParams: {
        scope: 'openid offline_access',
        device: 'Mobile device'
      }
    }, function(profile, token, accessToken, state, refreshToken) {
      // Success callback
      store.set('profile', profile);
      store.set('token', token);
      store.set('refreshToken', refreshToken);
      $location.path('/');
    }, function(error) {
      console.log("There was an error logging in", error);
    });
  };

    $scope.logout = function() {
        auth.signout();
        store.remove('token');
        store.remove('profile');
        store.remove('refreshToken');
        $location.path('/');
    };
});

app.js

var myApp = angular.module('myApp', 
                        [
                            'ngRoute',
                            'ngResource',
                            'auth0',
                            'angular-storage',
                            'angular-jwt'
                        ]);
myApp.run(function($rootScope, auth, store, jwtHelper, $location) {
    auth.hookEvents();  

  var refreshingToken = null;
  $rootScope.$on('$locationChangeStart', function() {
    var token = store.get('token');
    var refreshToken = store.get('refreshToken');
    if (token) {
      if (!jwtHelper.isTokenExpired(token)) {
        if (!auth.isAuthenticated) {
          auth.authenticate(store.get('profile'), token);
        }
      } else {
        if (refreshToken) {
          if (refreshingToken === null) {
            refreshingToken = auth.refreshIdToken(refreshToken).then(function(idToken) {
              store.set('token', idToken);
              auth.authenticate(store.get('profile'), idToken);
            }).finally(function() {
              refreshingToken = null;
            });
          }
          return refreshingToken;
        } else {
          $location.path('/login');
        }                       
      }
    }
  });    
});

myApp.config(function($routeProvider, authProvider, $httpProvider, $locationProvider,
  jwtInterceptorProvider){

  authProvider.init({
    domain: 'DOMAIN.eu.auth0.com',
    clientID: 'CLIENTID',
    loginUrl: '/'
  });  

  $routeProvider

    .when('/', {
        templateUrl: 'partials/home.html',
        controller: 'homeCtrl'
    })

    .when('/dashboard', {
        templateUrl: 'partials/dashboard.html',
        controller: 'dashCtrl',
        requiresLogin: true
    })

    .when('/capture', {
        templateUrl: 'partials/capture.html',
        controller: 'captureCtrl',
        requiresLogin: true
    })

    .when('/profile', {
        templateUrl: 'partials/profile.html',
        controller: 'profileCtrl',
        requiresLogin: true
    })

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

    $locationProvider.html5Mode({enabled:true, requireBase: false});

  jwtInterceptorProvider.tokenGetter = function(store, jwtHelper, auth) {
    var idToken = store.get('token');
    var refreshToken = store.get('refreshToken');
    // If no token return null
    if (!idToken || !refreshToken) {
      return null;
    }
    // If token is expired, get a new one
    if (jwtHelper.isTokenExpired(idToken)) {
      return auth.refreshIdToken(refreshToken).then(function(idToken) {
        store.set('token', idToken);
        return idToken;
      });
    } else {
      return idToken;
    }
  }   

  $httpProvider.interceptors.push('jwtInterceptor');
});

如您所见，在导航上我正在尝试执行ng-if="auth.isAuthenticated" and ng-if="!auth.isAuthenticated"，但它似乎什么也没做。

我还尝试了console.log(auth.isAuthenticated);，看看它是否有效，它总是给出“假”。

【问题讨论】：

尝试渲染值来查看，在<li> 标签中添加{{auth.isAuthenticated}} 看看那里是否可用？
@DanielDawes 我做了：$scope.authenticated = auth.isAuthenticated; &
注销 - {{authenticated}}

【解决方案1】：

您需要使用范围跟踪身份验证状态：

//NavCtrl.js
    $scope.login = function doAuth() {
      auth.signin({
        authParams: {
          scope: 'openid offline_access',
          device: 'Mobile device'
        }
      }, function(profile, token, accessToken, state, refreshToken) {
        // Success callback


        //Store the status in the scope 
        $scope.isAuthenticated = auth.isAuthenticated
        store.set('profile', profile);
        store.set('token', token);
        store.set('refreshToken', refreshToken);
        $location.path('/');
      }, function(error) {
        console.log("There was an error logging in", error);
      });
    };

在页面重新加载后处理重新验证：

//app.js
myApp.run(function($rootScope, auth, store, jwtHelper, $location) {
    auth.hookEvents();

  var refreshingToken = null;
  $rootScope.$on('$locationChangeStart', function() {
    var token = store.get('token');
    var refreshToken = store.get('refreshToken');
    if (token) {
      if (!jwtHelper.isTokenExpired(token)) {
        if (!auth.isAuthenticated) {
          auth.authenticate(store.get('profile'), token);


          //Store the status in the scope 
          $rootScope.isAuthenticated = auth.isAuthenticated
        }
      } else {
        if (refreshToken) {
          if (refreshingToken === null) {
            refreshingToken = auth.refreshIdToken(refreshToken).then(function(idToken) {
              store.set('token', idToken);
              auth.authenticate(store.get('profile'), idToken);
            }).finally(function() {
              refreshingToken = null;
            });
          }
          return refreshingToken;
        } else {
          $location.path('/login');
        }
      }
    }
  });
});

然后在html中：

<li ng-if="!isAuthenticated"><a href="" ng-click="login()">Login</a></li>

【讨论】：

是的，似乎可以做到。唯一还没有工作的是，当我按 l 注销时，它似乎没有刷新我的页面。因此注销按钮留在那里，直到我手动刷新它。有没有简单的解决方法？
它确实回到了主页；虽然导航栏没有更新（除非我刷新），只是为了清楚
您还需要更新范围。在logout() 函数中将isAuthenticated 设置为false。
