使用Firebase进行Flutter用户注册:添加额外的用户信息(年龄，用户名) [英] Flutter user registration with Firebase: Add extra user information (age, username)

问题描述

在phpMySQL背景下，我有点迷路了.

With a phpMySQL background, I'm a little bit lost.

按照教程，我已经成功地使用Flutter和Firebase Auth(简单的电子邮件/密码方法)创建了注册过程.

I've successfully created a registration process with Flutter and Firebase Auth (simple email/password method) following a tutorial.

我想在注册表格中添加一个用户名"和年龄"字段.

I would like add a "username" and "age" field to the registration form.

在Firebase中，我创建了一个名为用户"的数据库，其中有一个字符串键入"userid"，该字符串为空.但这是否有必要?我下一步该怎么办?它如何映射到身份验证表中的用户UID?如何推动它并使用Flutter进行检索?

In Firebase I've created a database called "users", and in it a String typed "userid" that's blank. But is it even necessary? What do I do next? How is it mapped to the User UID in the authentication table? How do I push it and retrieve it with Flutter?

我对这篇文章的浏览无济于事使用firebase添加额外的用户信息

I've explored this post to no avail Add extra User Information with firebase

如果有帮助，我的身份验证文件将包含以下内容:

If that helps, my authentication file contains this:

class Auth implements BaseAuth {
  final FirebaseAuth _firebaseAuth = FirebaseAuth.instance;

  Future<String> signIn(String email, String password) async {
    FirebaseUser user = await _firebaseAuth.signInWithEmailAndPassword(
        email: email, password: password);
    return user.uid;
  }

  Future<String> signUp(String email, String password) async {
    FirebaseUser user = await _firebaseAuth.createUserWithEmailAndPassword(
        email: email, password: password);
    return user.uid;
  }

尝试过:

Future<String> signUp(String email, String password) async {
    FirebaseUser user = await _firebaseAuth.createUserWithEmailAndPassword(
        email: email, password: password);

    Firestore.instance.collection('users').document().setData({ 'userid': user.uid, 'displayName': 'bobby' });

    return user.uid;
  }

但是它会引发错误:

5.17.0 - [Firebase/Firestore][I-FST000001] Write at users/-L_6e1CFkU1YchxsSPay failed: Missing or insufficient permissions.

推荐答案

好的，以上似乎都很好. 只需按照以下内容将数据库规则从false更改为true:

Ok seems the above is all good. Just had to change the Database rules from false to true as per the below post:
