尝试使用 firebase 对用户进行身份验证.使用 firebase 2.xx 启动我的应用程序，但即使在升级到 Firebase 3.xx 后，抛出错误onAuthStateChanged 不是函数".

这就是我的登录功能的样子-

.controller('HomeCtrl', ['$scope','$location','CommonProp','$firebaseAuth', '$firebaseObject',function($scope,$location,CommonProp,$firebaseAuth,$firebaseObject) {var firebaseObj = $firebaseObject(rootRef);var loginObj = $firebaseAuth(firebaseObj);$scope.SignIn = 函数($scope，用户){event.preventDefault();//防止表单刷新var 用户名 = user.email;var 密码 = 用户名.密码;loginObj.$signInWithEmailAndPassword({电子邮件:用户名，密码:密码}).then(功能(用户){//成功回调console.log('认证成功');$location.path("/欢迎");CommonProp.setUser(user.password.email);}, 函数(错误){//失败回调控制台日志(错误)；});}}]);

解决方案

您的问题是您正在将 $firebaseObject 传递给 $firebaseAuth().

因此，请确保您正在初始化您的 [$firebaseAuth][1] 对象，如下所示，然后您的代码应该可以正常工作.

var loginObj = $firebaseAuth();

正在使用 jsFiddle 进行演示.

您可以在此处查看 AngularFire2 的文档>

Trying to authenticate an user using firebase. Started my app using firebase 2.xx but even after upgrading to Firebase 3.xx, throwing error "onAuthStateChanged is not a function".

This is how my login function looks like-

.controller('HomeCtrl', ['$scope','$location','CommonProp','$firebaseAuth', '$firebaseObject',function($scope,$location,CommonProp,$firebaseAuth,$firebaseObject) {

    var firebaseObj = $firebaseObject(rootRef);
    var loginObj = $firebaseAuth(firebaseObj); 

    $scope.SignIn = function($scope, user) {
    event.preventDefault(); // To prevent form refresh
    var username = user.email;
    var password = user.password;


    loginObj.$signInWithEmailAndPassword({
            email: username,
            password: password
        })
        .then(function(user) {
            // Success callback
            console.log('Authentication successful');
            $location.path("/welcome");
            CommonProp.setUser(user.password.email);
        }, function(error) {
            // Failure callback
            console.log(error);
        });
}
}]);

解决方案

Your problem is that you are passing a $firebaseObject to $firebaseAuth().

So make sure you are initializing your [$firebaseAuth][1] object like the following and then your code should work properly.

var loginObj = $firebaseAuth();

Working jsFiddle for demonstrating.
