基本上我想做的是根据用户身份验证状态更改状态。
当我在没有 $rootScope 的情况下执行 $state.go(); 时，我可以重定向到页面而不会出现错误，但是当我使用
$rootScope.$on('$stateChangeStart', 函数 (事件) {
$state.go();
event.preventDefault()
})
下面是 Controller 代码:
DiaryDashboard.controller('AppController',
['$scope', '$rootScope', '$localStorage', '$http', '$state'
, function ($scope, $rootScope, $localStorage, $http, $state) {
$rootScope.$on('$stateChangeStart', function (event, toState) {
if ($localStorage.userdetails &&
$localStorage.userdetails.isAuthenticated == true) {
//Check for Authentication state
//If not redirect to the state in the else clause
//Populate the $rootScope with user details
$rootScope.userdetails = $localStorage.userdetails;
//Switch to the parent state
$state.go();
event.preventDefault();
} else {
//If User not authenticated
//GO to the Authentication State
$state.go('auth');
event.preventDefault();
}
})
}]);
最佳答案
这里最重要的是理解这一点:
Do not redirect if not needed. Other words, if user is already redirected to intended state - we should leave... There is a working plunker with similar solution.
查看此问答:
Angularjs ui-router. How to redirect to login page
调整后的代码:
$rootScope.$on('$stateChangeStart', function (event, toState) {
var isNavigatingToAuth = toState.name === "Auth";
if(isNavigatingToAuth){
return; // no need to redirect
}
if ($localStorage.userdetails &&
$localStorage.userdetails.isAuthenticated == true)
