在admin app | firestore SDK NODEJS中以注册用户身份登录

const admin = require('firebase-admin');

// 初始化Firebase应用程序
admin.initializeApp({
  credential: admin.credential.applicationDefault(),
  databaseURL: 'https://your-project-id.firebaseio.com'
});

// 获取Firestore实例
const db = admin.firestore();

// 注册用户
function registerUser(email, password) {
  return admin.auth().createUser({
    email: email,
    password: password
  })
  .then((userRecord) => {
    // 将用户信息保存到Firestore数据库中
    return db.collection('users').doc(userRecord.uid).set({
      email: email,
      role: 'user'
    });
  })
  .catch((error) => {
    console.error('Error creating user:', error);
    throw error;
  });
}

// 用户登录
function loginUser(email, password) {
  return admin.auth().signInWithEmailAndPassword(email, password)
  .then((userCredential) => {
    // 获取用户信息
    return db.collection('users').doc(userCredential.user.uid).get();
  })
  .then((doc) => {
    if (doc.exists) {
      const user = doc.data();
      console.log('Logged in as:', user.email);
      console.log('Role:', user.role);
    } else {
      console.log('User not found');
    }
  })
  .catch((error) => {
    console.error('Error signing in:', error);
    throw error;
  });
}
