How to get user info (email, name, etc.) from the react-native-fbsdk?

Question

I'm trying to access the user's email and name to setup and account when a user authenticates with Facebook. I've ready the documentations for react-native-fbsdk but I'm not seeing it anywhere.

Answer 1

The accepted answer uses fetch but the SDK is capable of doing this request as well... So in case anyone is wondering, this is how it can be done with the SDK.

let req = new GraphRequest('/me', {
    httpMethod: 'GET',
    version: 'v2.5',
    parameters: {
        'fields': {
            'string' : 'email,name,friends'
        }
    }
}, (err, res) => {
    console.log(err, res);
});

You could do something like this (which is a boiled down version of what I'm doing in my app):

<LoginButton
  publishPermissions={['publish_actions']}
  readPermissions={['public_profile']}
  onLoginFinished={
    (error, result) => {
      if (error) {
        console.log('login has error: ', result.error)
      } else if (result.isCancelled) {
        console.log('login is cancelled.')
      } else {
        AccessToken.getCurrentAccessToken().then((data) => {
          const { accessToken } = data
          initUser(accessToken)
        })
      }
    }
  }
  onLogoutFinished={logout} />

// initUser function

initUser(token) {
  fetch('https://graph.facebook.com/v2.5/me?fields=email,name,friends&access_token=' + token)
  .then((response) => response.json())
  .then((json) => {
    // Some user object has been set up somewhere, build that user here
    user.name = json.name
    user.id = json.id
    user.user_friends = json.friends
    user.email = json.email
    user.username = json.name
    user.loading = false
    user.loggedIn = true
    user.avatar = setAvatar(json.id)      
  })
  .catch(() => {
    reject('ERROR GETTING DATA FROM FACEBOOK')
  })
}

That will help you, this is worked for me

import React, { Component } from 'react';
import { View } from 'react-native';
import { LoginManager,LoginButton,AccessToken,GraphRequest,GraphRequestManager} from 'react-native-fbsdk';

export default class App extends Component<{}> {

  render() {
    return (
      <View style={styles.container}>

        <LoginButton
          publishPermissions={["publish_actions"]}
          onLoginFinished={
            (error, result) => {
              if (error) {
                alert("login has error: " + result.error);
              } else if (result.isCancelled) {
                alert("login is cancelled.");
              } else {
                AccessToken.getCurrentAccessToken().then(
                  (data) => {
                    const infoRequest = new GraphRequest(
                      '/me?fields=name,picture',
                      null,
                      this._responseInfoCallback
                    );
                    // Start the graph request.
                    new GraphRequestManager().addRequest(infoRequest).start();
                  }
                )
              }
            }
          }
          onLogoutFinished={() => alert("logout.")}/>
      </View>
    );
  }

  //Create response callback.
  _responseInfoCallback = (error, result) => {
    if (error) {
      alert('Error fetching data: ' + error.toString());
    } else {
      alert('Result Name: ' + result.name);
    }
  }
}
