#鸿蒙通关秘籍#如何在鸿蒙HarmonyOS TCP客户端应用中发送和接收消息？

// 发送消息到服务端
tcpSocket.send({ data: "Hello Server!" }).then(() => {
  console.log('消息发送成功');
}).catch((e) => {
  console.log('消息发送失败: ' + e.message);
});

// 监听接收的消息事件
tcpSocket.on("message", (value) => {
  let messageReceived = new TextDecoder("utf-8").decode(value.message);
  console.log("收到来自服务端的消息: " + messageReceived);
});
