将服务用于View AngularJS

Question

我有angularJS服务的问题.

我有简单的服务:

angular.module('mainApp.services', []).factory('AuthService',
function ($http) {
    //var currentUser = null;
    //var authorized = false;

    //AutoLogin for testing
    var currentUser={email: "example@example.com", id: "15"};
    var authorized=true;

    // initial state says we haven't logged in or out yet...
    // this tells us we are in public browsing
    var initialState = false;

    return {
        initialState:function () {
            return initialState;
        },
        login:function (userData) {
            //Call API Login
            currentUser = userData;
            authorized = true;
            initialState = false;
        },
        logout:function () {
            currentUser = null;
            authorized = false;
        },
        isLoggedIn:function () {
            return authorized;
        },
        currentUser:function () {
            return currentUser;
        },
        authorized:function () {
            return authorized;
        }
    };
});

然后我有一个简单的控制器

.controller('NavbarTopCtrl', ['$scope','$modal','AuthService',function($scope,$modal,authService) {
    $scope.authService=authService;  //IS good practice?
    console.log($scope);
}])

我无法将我的服务用于View.我做了简单的技巧,工作正常.

$scope.authService=authService

但是如何在我的视图(HTML文件)中调用Service而不使用它？

在视图中使用服务通常是一种不好的做法.视图应仅包含表示逻辑.在您的示例中,您可以尝试仅传递用户对象,而不是将整个服务传递给视图.例如$scope.currentUser = authService.currentUser().
