#鸿蒙通关秘籍#如何实现鸿蒙HarmonyOS中的TCP客户端通信？

import socket from '@ohos.net.socket';

// 创建TCP Socket实例
let tcpSocket = socket.constructTCPSocketInstance();

// 绑定本地IP和端口
let localAddress = { address: "0.0.0.0", port: 9990, family: 1 };
tcpSocket.bind(localAddress).then(() => {
  console.log('绑定成功');
}).catch((e) => {
  console.log('绑定失败: ' + e.message);
});

// 连接到服务端
let serverAddress = { address: "服务端IP", port: 服务端端口, family: 1 };
tcpSocket.connect({ address: serverAddress }).then(() => {
  console.log('连接成功');
}).catch((e) => {
  console.log('连接失败: ' + e.message);
});
