一旦用户登录到我们的应用程序,用户凭据就会存储到本地存储中。如果用户路由到登录状态,因为他已经登录,则会在控制台中显示以下错误:
Uncaught Error: [$rootScope:infdig] http://errors.angularjs.org/1.3.10/$rootScope/infdig?p0=10&p1=%5B%5D
用于检查本地存储并重定向用户的代码
$rootScope.$on('$stateChangeStart', function(event, toState, toParams, fromState, fromParams) {
// Grab the user from local storage and parse it to an object
var user = JSON.parse(localStorage.getItem('user'));
// If there is any user data in local storage then the user is quite
// likely authenticated.
if(!user) {
if(toState.name !== 'login.signin'){
//go to application "login" state
$state.go('login.signin');
event.preventDefault();
}
}
else{
// The user's authenticated state gets flipped to
// true so we can now show parts of the UI that rely
// on the user being logged in
$rootScope.authenticated = true;
// Putting the user's data on $rootScope allows
// us to access it anywhere across the app.
// Here we are grabbing what is in local storage
$rootScope.currentUser = user;
if(toState.name === "login.signin") {
// go to the application "dashboard" state
$state.go('app.dashboard');
// Preventing the default behavior allows us to use $state.go
// to change states
event.preventDefault();
}
}
});
我的解决方案是
Changing $stateChangeStart with $stateChangeSuccess
当你的摘要圈运行时,你不能改变任何范围变量,我认为你使用$timeout。 在你定义它的地方注入$timeout
$rootScope.$on('$stateChangeSuccess', function(event, toState, toParams, fromState, fromParams) {
$timeout(function(){
var user = JSON.parse(localStorage.getItem('user'));
// If there is any user data in local storage then the user is quite
// likely authenticated.
if(!user) {
if(toState.name !== 'login.signin'){
//go to application "login" state
$state.go('login.signin');
event.preventDefault();
}
}
else{
// The user's authenticated state gets flipped to
// true so we can now show parts of the UI that rely
// on the user being logged in
$rootScope.authenticated = true;
// Putting the user's data on $rootScope allows
// us to access it anywhere across the app.
// Here we are grabbing what is in local storage
$rootScope.currentUser = user;
if(toState.name === "login.signin") {
// go to the application "dashboard" state
$state.go('app.dashboard');
// Preventing the default behavior allows us to use $state.go
// to change states
event.preventDefault();
}
}
});
