如何抓取登录用户?
我这样做: console.log('登录...'); this.afAuth.auth.signInWithEmailAndPassword(this.email,this.password);
但是文档并不清楚如何让用户使用代码。它们在模板中显示了一种方式,但我需要存储当前用户。

获取当前用户:
let user = AngularFireAuth.auth.currentUser;
// returns user object
出于某种原因,每次页面刷新都会导致currentUser消失,我将用户ID(UID)存储在本地存储中,因此我能够记住用户并在以后引用Firestore:
localStorage.setItem('userUID', user.uid);
// ...
let userID = localStorage.getItem('userUID');
AngularFirestore.firestore.collection('users')
.doc(userID)
// ...
注销时,您只需注销用户并删除本地存储值:
logout() {
AngularFireAuth.auth.signOut().then(() => {
localStorage.removeItem('userUID');
};
}

我明白了!
console.log('Logging in...');
this.afAuth.auth.signInWithEmailAndPassword(this.email, this.password).then((user) => {
this.user = this.afAuth.authState;
});

AngularFireAuth.authState是一个Observable,因此您可以对其进行订阅,然后获取用户实例:
private user: firebase.User;
constructor(public afAuth: AngularFireAuth) {
afAuth.authState.subscribe(user => {
this.user = user;
});
}

我在网上创建的解决方案,无论页面刷新都有效:
AngularFireAuth.authState.pipe(first()).toPromise();
