我是AngularJS的新手,我尝试处理用户身份验证。
我确保非连接用户无法访问受限制的路由:
app.js
.config(function ($routeProvider) {
$routeProvider
.when('/myroute', {
templateUrl: 'views/myroute.html',
controller: 'MyrouteCtrl',
access: {
isFreeAccess: false
}
})
...
.run( function ($rootScope, $location, Auth) {
$rootScope.$on('$routeChangeStart', function(currRoute, prevRoute){
if (prevRoute.access != undefined) {
// if route requires auth and user is not logged in
if (!prevRoute.access.isFreeAccess && !Auth.isLogged) {
// redirects to index
$location.path('/');
}
}
AuthService.js
.factory('Auth', function () {
var user;
return{
setUser : function(aUser){
user = aUser;
},
isLoggedIn : function(){
return(user)? user : false;
}
}
});
login.js
$scope.login = function(user) {
$http({
url: ***,
method: "POST",
data: user,
headers: {'Content-Type': 'application/json'}
}).success(function (data, status, headers, config) {
$scope.persons = data;
Auth.setUser(data); //Update the state of the user in the app
$location.path("/");
}).error(function (data, status, headers, config) {
$scope.status = status;
});
用户状态在他连接时存储。现在我想在导航栏中显示新项目。
的index.html
<div ng-include src="'views/navbar.html'"></div>
navbar.js
.controller('NavbarCtrl', function ($scope) {
$scope.items = [
{'name': 'Home', "needAuthentication": false},
{'name': 'About', "needAuthentication": false},
{'name': 'Settings', "needAuthentication": true},
{'name': 'Logout', "needAuthentication": true}
];
});
navbar.html
<div ng-controller="NavbarCtrl" class="collapse navbar-collapse navbar-ex1-collapse" role="navigation">
<ul class="nav navbar-nav navbar-right">
<li ng-repeat="item in items ">
<a ng-if="item.needAuthentication == false || (item.needAuthentication == true && Auth.isLoggedIn())" href="#{{item.name}}">{{item.name}}</a>
</li>
</ul>
</div>
当用户启动应用时:
1)他尚未连接
ng-if="item.needAuthentication == false || (item.needAuthentication == true && Auth.isLoggedIn ())"
&#39;首页&#39;和&#39;关于&#39;项目显示。
2)然后他连接到应用程序,但导航栏不会被其他项目重新渲染(&#39;设置&#39;&#39;退出&#39;)。
实现这一目标的正确方法是什么?使用指令/将其绑定到模型/或其他东西?
事先提前答案 0 :(得分:1)
我认为isLoogged
函数应该在定义user
时返回true
尝试更改
return(user)? user : false;
到
return(user)? true : false;
