我有4个状态:仪表板,dahboard.main,dashboard.minor,登录。
仪表板是抽象的,它是.minor和.main状态的父状态。
下面是我的代码:
仪表板是抽象的,它是.minor和.main状态的父状态。
下面是我的代码:
.state('dashboard',{ url: "/dashboard",abstract: true,templateUrl: "views/dashboard.html",resolve: { auth: function ($q,authenticationSvc) { var userInfo = authenticationSvc.getUserInfo(); if (userInfo) { return $q.when(userInfo); } else { return $q.reject({ authenticated: false }); } } },controller: "DashboardCtrl",data: { pageTitle: 'Example view' } }) .state('dashboard.main',{ url: "",templateUrl: "views/main.html",data: { pageTitle: 'Main view' } })
正如你在仪表板状态我看到解决选项。通过这个,我想重定向用户到登录页面,如果他没有授权。为此,我使用特殊的authenticationSvc服务:
.factory("authenticationSvc",["$http","$q","$window",function ($http,$q,$window) { var userInfo; function login(email,password) { var deferred = $q.defer(); $http.post("/api/login",{ email: email,password: password }) .then(function (result) { if(result.data.error == 0) { userInfo = { accessToken: result.data.accessToken }; $window.sessionStorage["userInfo"] = JSON.stringify(userInfo); deferred.resolve(userInfo); } else { deferred.reject(error); } },function (error) { deferred.reject(error); }); return deferred.promise; } function getUserInfo() { return userInfo; } return { login: login,logout: logout,getUserInfo: getUserInfo }; }]);
我检查auth值在config:
.run(function($rootScope,$location,$state) { $rootScope.$state = $state; $rootScope.$on("routeChangeSuccess",function(userInfo) { consol.log(userInfo); }); $rootScope.$on("routeChangeError",function(event,current,prevIoUs,eventObj) { if(eventObj.authenticated === false) { $state.go('login'); } }); });
关键是,如果不需要,不重定向===如果已经重定向到预期的状态。有
