基于Firebase身份验证在Firestore中创建相同的用户

要实现在Firestore中创建相同用户，需要使用Firebase Authentication模块。以下是创建用户的代码示例：

//引入Firebase模块
import * as firebase from "firebase/app";
import "firebase/auth";
import "firebase/firestore";

//初始化Firebase
const config = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_AUTH_DOMAIN",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_STORAGE_BUCKET",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
  appId: "YOUR_APP_ID"
};

firebase.initializeApp(config);

//使用Firebase Authentication模块创建用户
firebase.auth().createUserWithEmailAndPassword(email, password)
  .then((userCredential) => {
    //用户创建成功后，将用户信息存入Firestore
    const db = firebase.firestore();
    db.collection("users").doc(userCredential.user.uid).set({
      email: email,
      username: username
    })
    .then(() => {
      console.log("User successfully added to Firestore!");
    })
    .catch((error) => {
      console.error("Error adding user to Firestore: ", error);
    });
  })
  .catch((error) => {
    console.error("Error creating user: ", error);
  });

此代码将创建一个新用户并将用户信息存储到Firestore中。请确保使用正确的项目配置、集合和字段名称。
