Question

我有一个Firebase AngularJS应用程序，我使用FirebaseSimpleLogin来执行身份验证，但我在理解如何将登录用户保留在我的身上时遇到了一些麻烦应用。每次登录并刷新页面时，我都会看到我不再进行身份验证。我知道登录后会生成一个令牌，用于对用户进行身份验证，但我是否需要在每个页面上使用此令牌对它们进行身份验证，如果是这样，我会在应用程序和firebase之间产生任何类型的开销？

执行登录/验证的应用程序部分

var ref = new Firebase("https://xxx.firebaseio.com/");
angularFireAuth.initialize(ref, {scope: $scope, name: "user", path:"/login"});

    // Used to authenticate user at a later time
$scope.auth = function(token, callback)
{

    ref.auth(token, function(error, data) {

        if(error) 
        {
            console.log("Login Failed!", error);
        } 
        else 
        {
            $scope.$apply(function()
            {
                $scope.user = data.auth;
            }); 
        }

        if (typeof callback === 'function')
        {
            callback(error,data);
        }

    });
};


    // Login to fetch authentication token to be used by $scope.auth()
$scope.login = function()
{   
    angularFireAuth.login("password", { 
        email: $scope.credentials.email,
        password: $scope.credentials.password
    });
};


    // On login stores user within $scope
$scope.$on("angularFireAuth:login", function(evt, user) {
    $scope.$apply(function()
    {
                 // Is it possible to save this user accross my application not just in this $scope
             $scope.user = user; 

    });
});

以下是捕获电子邮件/密码组合的标记

<div class="container-single" center>
               <h3>Sign in</h3>
               <input type="text" ng-model="credentials.email" placeholder="Username" />
               <input type="password" ng-model="credentials.password" placeholder="Password" />
               <input type="checkbox" id="checkbox-1" name="checkbox-1" /> <label>Remember my password</label>
               <button ng-click="login()">Sign in</button>
           </div>

如果您使用angularFireAuth，则无需自行进行任何身份验证。只需检查$scope.user值，查看用户是否在每个视图中都已登录。

var ref = new Firebase("https://xxx.firebaseio.com/");
angularFireAuth.initialize(ref, {scope: $scope, name: "user", path:"/login"});

$scope.login = function() {   
  angularFireAuth.login("password", { 
    email: $scope.credentials.email,
    password: $scope.credentials.password
  });
};

成功登录后，$scope.user会自动设置为用户详细信息。
