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,

      },
      authTypeOption: {
        Google: 0,
        Facebook: 2,
        Twitter: 1
      },
      FirebaseTypeKey: 'FirebaseType'
    }
  },
  created() {
    this.FirebaseInte()
    this.getFirebaseRedirectResult()
  },
  mounted() {
    // this.getFirebaseRedirectResult()
  },
  methods: {
    FirebaseInte() { // 初始化
