Question

我创建了用户登录并注册Android应用程序。我使用Firebase Auth For User Register。我希望当用户注册A计数器值将添加到我的数据库时为该用户。它将为所有用户创建。计数器值将为“0”。

Answer 1

也许FirebaseAuth.AuthStateListener是您需要的。见https://firebase.google.com/docs/reference/android/com/google/firebase/auth/FirebaseAuth.AuthStateListener

FirebaseAuth fa = FirebaseAuth.getInstance();

fa.addAuthStateListener(new FirebaseAuth.AuthStateListener() { 

    @Override
    onAuthStateChanged(FirebaseAuth auth) {
        //not sure how to check for the login event. but this should work too
        FirebaseUser currentUser = auth.getCurrentUser()
        if(currentUser != null) {
            //add your data in your database.
        }
    }
});

我认为firebase云功能对此非常有用。你能看一下authentication triggers吗？

您的nodeJS代码是这样的，请查看入门部分here

exports.incrementUserount = functions.auth.user().onCreate(event => { // increment the counter in the database here });

自动为Firebase数据库中的每个用户创建一个值
