如何使用expo-firebase-reacaptcha？

npm install expo-firebase-recaptcha firebase

import firebase from 'firebase/app';
import 'firebase/auth';
import 'firebase/firestore';

const firebaseConfig = {
  // 在此处添加您的Firebase配置信息
};

if (!firebase.apps.length) {
  firebase.initializeApp(firebaseConfig);
}

export default firebase;

import React, { useState } from 'react';
import { View, Button } from 'react-native';
import { ReCaptcha } from 'expo-firebase-recaptcha';
import firebase from './firebase';

export default function LoginScreen() {
  const [token, setToken] = useState('');

  const handleVerify = async () => {
    const token = await this.recaptchaRef.verify();
    setToken(token);
  };

  const handleLogin = () => {
    // 使用token进行登录验证
    // 您可以将token发送到服务器进行验证，或者使用Firebase的身份验证服务进行验证
  };

  return (
    <View>
      <ReCaptcha
        ref={(ref) => (this.recaptchaRef = ref)}
        firebaseConfig={firebase.app().options}
        onVerify={handleVerify}
      />
      <Button title="登录" onPress={handleLogin} />
    </View>
  );
}
