Firebase reauthenticateAndRetrieveDataWithCredential问题 [英] Firebase reauthenticateAndRetrieveDataWithCredential problems

问题描述

方法reauthenticateAndRetrieveDataWithCredential需要credential.

我尝试了此操作，但它给了我一个错误:

I tried this and it gives me an error:

const user = firebase.auth().currentUser;
const credential = firebase.auth.OAuthCredential;
await user.reauthenticateAndRetrieveDataWithCredential(credential);
await user.updateEmail(email);
return email;

错误消息

reauthenticateAndRetrieveDataWithCredential失败:第一个参数"credential"必须是有效的凭据.

reauthenticateAndRetrieveDataWithCredential failed: First argument "credential" must be a valid credential.

我只有宣誓身份验证(没有电子邮件和密码).因此，我无法弄清credential firebase的需求.有帮助吗?

I only have oath authentication (no email + password). So I can't figure out what credential firebase need. Any help?

修改: 由于某些原因，我的firebase.auth.OAuthCredential或(firebase.auth.AuthCredential)返回未定义.用户已登录/授权.

For some reason my firebase.auth.OAuthCredential or (firebase.auth.AuthCredential) return undefined. User is signedIn/authed.

推荐答案

在Vue.js项目中遇到此问题，我们在其中有一个firebase.js文件来处理模块导入和导出的const.

Ran into this issue in a Vue.js project where we have a firebase.js file that handles module imports and exports of const.

希望这可以帮助某人在使用类似设置时节省时间.

Hoping this will help someone save time when using a similar setup.

文件:firebase.js

import firebase from 'firebase/app'
import 'firebase/auth'
import 'firebase/database'


// Initialize Firebase
const app = firebase.initializeApp(options)
export const fb = firebase
export const auth = app.auth()
export const db = app.database()
export const functions = app.functions()

其他脚本文件中或*.vue

import { fb, auth } from './firebase.js'
...
changePassword() {
  if (yourFormValidation == true) {
    let user = auth.currentUser

    const credentials = fb.auth.EmailAuthProvider.credential(
      user.email,
      this.current_password
    )
    user.reauthenticateAndRetrieveDataWithCredential(credentials)
      .then(() => {
        user.updatePassword(this.new_password)
          .then(() => {
            console.log('your password was successfully changed.')
          })
          .catch(error => console.log(error))
      })
      .catch(error => console.log(error.message))
  }
}

我遇到Cannot read property 'credential' of undefined" ...

Where I was running into Cannot read property 'credential' of undefined"...

仅导入{ auth } from './firebase.js，然后调用auth.EmailAuthProvider().

如何访问在 firebase.auth()上找到的其他类 ...

How to access other classes found on firebase.auth()...

firebase.js

export const fb = firebase

import { fb, auth } from './firebase.js'编写函数的位置

调用fb.auth.EmailAuthProvider.credential()或其他需要的类
