问题描述
您好，我是 angularJS 的新手，一直在尝试根据用户标准阻止访问某些状态.
Hello I'm new to angularJS and have been trying to prevent access to certain states based on user critera.
这个，来自 ui-router 的常见问题 准确地描述了我想要做什么，但我无法让它正常工作.除了数据对象之外，我还需要什么才能完成此操作?
This, from ui-router's FAQ describes exactly what I want to do, but I cant get it to work properly. What do I need to but in the data object exactly to accomplish this?
(我看到有人在一些博客文章教程中输入true"并像我一样使用它，但这似乎不起作用，因为我收到一个错误，提示没有定义需要管理)
(I saw someone throwing in "true" on some blog post tutorial and using it like how I have, but that doesnt seem to work because I get an error that says needAdmin is not defined)
这是我的代码:
angular.module('courses').config(['$stateProvider',
function($stateProvider) {
// Courses state routing
$stateProvider.
state('listCourses', {
url: '/courses',
templateUrl: 'modules/courses/views/list-courses.client.view.html'
}).
state('createCourse', {
url: '/courses/create',
templateUrl: 'modules/courses/views/create-course.client.view.html',
data: {
needAdmin: true
}
}).
state('viewCourse', {
url: '/courses/:courseId',
templateUrl: 'modules/courses/views/view-course.client.view.html'
}).
state('editCourse', {
url: '/courses/:courseId/edit',
templateUrl: 'modules/courses/views/edit-course.client.view.html',
data: {
needAdmin: true
}
});
}
]);
angular.module('courses').run(['$rootScope', '$state', 'Authentication', function($rootScope, $state, Authentication) {
$rootScope.$on('$stateChangeStart', function(e, to) {
var auth = Authentication;
console.log(auth.user.roles[0]);
if (to.data.needAdmin && auth.user.roles[0] !== 'admin') {
e.preventDefault();
$state.go('/courses');
}
});
}]);
推荐答案
如果状态没有 data，则 to.data 是未定义的.试试这个:
If a state has no data, then to.data is undefined. Try this:
if (to.data && to.data.needAdmin && auth.user.roles[0] !== 'admin') {
