作为Tcp客户端的React Native App

import React, { useEffect, useState } from 'react';
import { View, Text } from 'react-native';
import { WebSocket } from 'react-native-websocket';

const TcpClient = () => {
  const [message, setMessage] = useState('');

  useEffect(() => {
    const ws = new WebSocket('wss://your-tcp-server-address');

    ws.onopen = () => {
      console.log('WebSocket connected');
      ws.send('Hello Server!');
    };

    ws.onmessage = (event) => {
      setMessage(event.data);
    };

    ws.onerror = (error) => {
      console.error('WebSocket error:', error);
    };

    ws.onclose = () => {
      console.log('WebSocket closed');
    };

    return () => {
      ws.close();
    };
  }, []);

  return (
    <View>
      <Text>{message}</Text>
    </View>
  );
};

export default TcpClient;
