Angularjs UI的路由器。如何重定向到登录页面 [英] Angularjs ui-router. How to redirect to login page
问题描述
我有4种状态:仪表 dahboard.main dashboard.minor 登录即可。
仪表盘是抽象的,它是.minor和。主要状态的父状态。
下面是我的code:
I have 4 states: dashboard, dahboard.main, dashboard.minor, login. dashboard is abstract and it is a parent state for .minor and .main states. Below is my code:
.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 $q.reject({ authenticated: false });
}
}
},
controller: "DashboardCtrl",
data: { pageTitle: 'Example view' }
})
.state('dashboard.main', {
url: "",
templateUrl: "views/main.html",
controller: "DashboardCtrl",
data: { pageTitle: 'Main view' }
})
正如你在仪表盘状态看,我有决心选项。这个我想重定向用户,如果他没有被授权到登录页面。为此,我使用特殊的 authenticationSvc 服务:
.factory("authenticationSvc", ["$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
};
$window.sessionStorage["userInfo"] = JSON.stringify(userInfo);
deferred.resolve(userInfo);
}
else {
deferred.reject(error);
}
}, function (error) {
deferred.reject(error);
});
return deferred.promise;
}
function getUserInfo() {
return userInfo;
}
return {
login: login,
logout: logout,
getUserInfo: getUserInfo
};
}]);
我检查AUTH值配置
.run(function($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) {
$state.go('login');
}
});
});
但不幸的是,当我去我的网站的根或仪表盘状态我得到一个空白页。有什么不对这个code?谢谢!
But unfortunately when I go to my website root or dashboard state I get an empty page. What is wrong with this code? Thanks!
推荐答案
的一点是,不要重定向。有有类似的解决方案工作plunker
The point is, do not redirect if not needed === if already redirected to intended state. There is a working plunker with similar solution
.run(function($rootScope, $location, $state, authenticationSvc) {
$rootScope.$on( '$stateChangeStart', function(e, toState , toParams
, fromState, fromParams) {
var isLogin = toState.name === "login";
if(isLogin){
return; // no need to redirect
}
// now, redirect only not authenticated
var userInfo = authenticationSvc.getUserInfo();
if(userInfo.authenticated === false) {
e.preventDefault(); // stop current execution
$state.go('login'); // go to login
}
});
});
