在 firebase 3.0 中似乎不可能使用 session 持久性。
这在以前的版本中是可能的:
https://www.firebase.com/docs/web/guide/login/password.html
authWithPassword() takes an optional third parameter which is an object containing any of the following settings:
remember - String
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.
在 3.0 版本中没有提到可选的第三个参数:
https://firebase.google.com/docs/reference/js/firebase.auth.Auth#signInWithEmailAndPassword
signInWithEmailAndPassword(email, password)
returns firebase.Promise containing non-null firebase.User
此外，在新控制台 ( https://console.firebase.google.com/ ) 中，我找不到更改默认持久性的选项。
最佳答案
可能还值得一提的是，您需要等待 auth 状态解析。根据文档:
The recommended way to get the current user is by setting an observer on the Auth object:
firebase.auth().onAuthStateChanged(function(user) {
if (user) {
// User is signed in.
} else {
// No user is signed in.
}
});
