推荐答案

您可以创建云函数触发器，在创建帐户时在用户集合"中创建用户文档.

You can create a cloud function trigger that creates a user document in a "users collection" when the account is created.

export const createUserDoc = functions.auth.user().onCreate(event => {
    const firebaseUser = event.data;
    const user = {
        name: firebaseUser.displayName || "No Name",
        email: firebaseUser.email
    };

    return firebase.firestore()
        .collection("users")
        .doc(firebaseUser.uid)
        .set(user);
});

之后，最简单的设置方法是使用 Firebase 扩展程序发送电子邮件:https://firebase.google.com/products/extensions/firestore-send-email
