var firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_PROJECT_ID.firebaseapp.com",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_PROJECT_ID.appspot.com",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
  appId: "YOUR_APP_ID"
};

firebase.initializeApp(firebaseConfig);

// 获取Google登录提供者
var provider = new firebase.auth.GoogleAuthProvider();

// 弹出Google登录窗口
firebase.auth().signInWithPopup(provider).then(function(result) {
  // 登录成功，获取用户信息
  var user = result.user;
  console.log(user);
}).catch(function(error) {
  // 登录失败，处理错误信息
  var errorCode = error.code;
  var errorMessage = error.message;
  console.log(errorCode, errorMessage);
});
