javascript - AngularFire:恢复匿名 session

Question

来自Simple Web Login文档，它声称您可以通过执行以下操作恢复 session :

var auth = new FirebaseSimpleLogin(chatRef, function(error, user) {
  ...
});

是否有 AngularFire 的等效项？

$firebaseSimpleLogin 构造函数将 firebase 引用作为其唯一参数..

具体来说，我想要做的是匿名登录一次并在刷新整个页面时恢复登录。这可以实现吗？

是否保留您的身份验证 session 取决于您传递给登录方法的参数。无论您使用 FirebaseSimpleLogin 还是 $firebaseSimpleLogin 在这里都无关紧要。

var auth = $firebaseSimpleLogin(ref);
$rootScope.$on('$firebaseSimpleLogin:login', function(user) {
   console.log('logged in', user.uid);
});

// automagically logs in the next time you call $firebaseSimpleLogin() after page refresh
auth.$login('anonymous', { rememberMe: true });

// does not automagically log in
auth.$login('anonymous');

更新从 Angular 1.x 和 Firebase 2.x 开始，此语法和行为已更改。

来自 Firebase 文档中的 remember 属性:

If not specified - or set to default - sessions are persisted for as long as you have configured in the Login & Auth tab of your App Dashboard. To limit persistence to the lifetime of the current window, set this to sessionOnly. A value of none will not persist authentication data at all and will end authentication as soon as the page is closed.

var auth = $firebaseAuth(ref);
$firebaseAuth.$onAuth(function(user) {
   console.log('logged ' + (user? 'in' : 'out'), user && user.uid);
});

// stays logged in for length specified in the app dashboard
auth.$authAnonymously();

// stays logged in until the browser closes
auth.$authAnonymously({ remember: 'sessionOnly' });

// does not stay logged in on page refresh
auth.$authAnonymously({ remember: 'none' });
