需要帮助人员,目前正在使用exponent并访问Exponent.Facebook.logInWithReadPermissionsAsync进行身份验证。任何人都有设置项目的指南。我找不到iOS文件夹,因为在facebook sdk的说明中,我需要在项目中添加几个库。这是我的main.js:
import Expo from 'expo';
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { Button } from 'react-native-elements';
class App extends React.Component {
authenticate = (token) => {
const provider = firebase.auth.FacebookAuthProvider;
const credential = provider.credential(token);
return firebase.auth().signInWithCredential(credential);
}
login = async () => {
const ADD_ID = 273131576444313
const options = {
permissions: ['public_profile', 'email'],
}
const {type, token} = await Expo.Facebook.logInWithReadPermissionsAsync(ADD_ID, options)
if (type === 'success') {
const response = await fetch(`https://graph.facebook.com/me?access_token=${token}`)
console.log(await response.json());
this.authenticate(token);
}
}
render() {
return (
<View style={styles.container}>
<Text>Open up main.js to start working on your app!</Text>
<Button
raised
onPress={this.login}
icon={{name: 'cached'}}
title='RAISED WITH ICON' />
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
});
Expo.registerRootComponent(App);
`

尝试在APP_ID周围添加单引号
