以下代码中firebaseConfig 参数从如下获取

import firebase from 'firebase/app'
import * as firebaseui from "firebaseui"
import "firebase/auth";
import "firebase/firestore";

export default {
  data() {
    return {
      ui: null,
      language: {
        zh_CN: 'zh_CN',
        en_US: 'en_US',
        hi_IN: 'hi_IN'
      },
      authTypeOption: {
        Google: 0,
        Facebook: 2,
        Twitter: 1
      },
      FirebaseTypeKey: 'goaWin-FirebaseType'
    }
  },
  created() {
    this.FirebaseInte()
    this.getFirebaseRedirectResult()
  },
  mounted() {
    // this.getFirebaseRedirectResult()
  },
  methods: {
    FirebaseInte() { // 初始化
      if (!firebase.apps.length) {
        var firebaseConfig = {
          apiKey: "xxxxxxxxxxx",

      // signInWithRedirect 为重定向
      firebase.auth().signInWithRedirect(provider)

      // signInWithPopup 为弹框形式登录

      //   // This gives you a Google Access Token. You can use it to access the Google API.

      });
    },
    getUUID(uid) { // 获取UUID并获取用户信息
