React native firebase - Facebook登录

Question

我按照 官方代码样本 由RNFB提供......代码如下

问题是，你没有得到过去的线。const facebookCredential = firebase.FacebookAuthProvider.credential(data.accessToken);......看来 firebase.FacebookAuthProvider 方法显示为未定义，所以你没有得到 facebookCredential 变背

import { firebase } from '@react-native-firebase/auth';

async function onFacebookButtonPress() {
  // Attempt login with permissions
  const result = await LoginManager.logInWithPermissions(['public_profile', 'email']);

  if (result.isCancelled) {
    throw 'User cancelled the login process';
  }

  // Once signed in, get the users AccesToken
  const data = await AccessToken.getCurrentAccessToken();

  if (!data) {
    throw 'Something went wrong obtaining access token';
  }

  // Create a Firebase credential with the AccessToken
  const facebookCredential = auth.FacebookAuthProvider.credential(data.accessToken);

  // Sign-in the user with the credential
  return auth().signInWithCredential(facebookCredential);
}

Answer 1

链接到的例子似乎缺少了声明一个 auth 变量。我们需要从导入的 firebase 调制。

而不是。

auth.FacebookAuthProvider

我们应该使用：

firebase.auth.FacebookAuthProvider
