我在每个 .state
中附加了数据属性来识别用户(经过身份验证的或公开的)如下(一个状态示例)
I have attached data attribute in each .state
to identify the user (authenticated or public) as following (one state example)
$stateProvider
.state('admin-panel.public.home', {
url: '/p',
templateUrl: 'app/public/home.tmpl.html',
controller: 'PublicHomeController',
controllerAs: 'ctrl',
data: {
requireLogin: false
}
});
我需要以用户(已验证和公开)的某些状态为例
I need to use the some state for both of user (authenticated and public) as an example
.state('403', {
url: '/403',
templateUrl: '403.tmpl.html',
controller: function($scope, $state, APP, Auth) {
$scope.app = APP;
$scope.goHome = function() {
if(Auth.isAuthenticated()){
$scope.requireLogin = true;
$state.go('admin-panel.default.home');
}
else{
$scope.requireLogin = false;
$state.go('admin-panel.public.home');
}
};
},
data: {
requireLogin: $scope.requireLogin
}
})
在这里,当经过身份验证的用户访问此状态时,我需要将 true 值传递给 requireLogin: true
以及当公共用户访问此状态时,我需要传递 false
值为 requireLogin: false
.如上所述,我在 controller
中检查了当前用户状态.如何将 $scope.requireLogin
绑定到数据属性?
Here when the authenticated user access this state I need to pass the true value to requireLogin: true
as well when public user access this state I need to pass the false
value as requireLogin: false
. I checked the current user status in the controller
as above. How can I bind the $scope.requireLogin
to data attribute?
ui-router
高手请指教解决办法???
Anyone in expert of ui-router
please tell a way to solve???
你可以用一种非常干净的方式解决你的问题.让我们从添加到 body
或 html
标签的全局控制器示例 GlobalCtrl
开始,例如 ng-controller="GlobalCtrl代码>.
You can solve your problem in a very cleaner way. Let's start with a global controller example GlobalCtrl
which is added to the body
or html
tag like ng-controller="GlobalCtrl
.
这样做将使我们能够在整个单页 Angular 应用程序中保持此 GlobalCtrl
的范围(当您使用 ui-router
时),我们可以避免使用$rootScope
的用法(实际上是在模仿 $rootScope
的用法).
Doing this will enable us to keep the scope of this GlobalCtrl
throughout your single page Angular app (as you are using ui-router
) and we can avoid the usage of $rootScope
(actually mimicking the usage of $rootScope
).
现在,在您的 GlobalCtrl
中定义如下内容:
Now, inside your GlobalCtrl
define something like this:
// Using an object to avoid the scope inheritance problem of Angular
// https://github.com/angular/angular.js/wiki/Understanding-Scopes
$scope.globalData = {};
// Will be called everytime before you start navigating to any state
$scope.$on('$stateChangeStart', function(event, toState, toParams) {
$scope.globalData.requireLogin = false;
var statesToLoginCheck = ['403', 'foo', 'bar']; // and other states on which you want to check if user is logged in or not
// If the current state on which we are navingating is allowed to check for login
if (statesToLoginCheck.indexOf(toState.name) > -1) {
if (Auth.isAuthenticated()) {
$scope.globalData.requireLogin = true;
$state.go('admin-panel.default.home');
} else {
$scope.globalData.requireLogin = false;
$state.go('admin-panel.public.home');
}
event.preventDefault();
return;
}
});
现在,由于 GlobalCtrl
的 $scope
在 body
或 html
中,那么每个状态或指令都会继承此 GlobalCtrl
的范围,然后您只需签入变量 $scope.globalData.requireLogin
的任何控制器.
Now, since $scope
of GlobalCtrl
is in body
or html
then every state or directive will inherit the scope of this GlobalCtrl
and then you simply have to check in your any controller of variable $scope.globalData.requireLogin
.
