从node.js打开和关闭连接的无限循环

const net = require('net');

const server = net.createServer((socket) => {
  console.log('Client connected');

  socket.on('data', (data) => {
    console.log(`Received data: ${data}`);
  });

  socket.on('end', () => {
    console.log('Client disconnected');
  });
});

server.listen(3000, () => {
  console.log('Server started');
});

const net = require('net');

const server = net.createServer();

server.on('connection', (socket) => {
  console.log('Client connected');

  socket.on('data', (data) => {
    console.log(`Received data: ${data}`);
  });

  socket.on('end', () => {
    console.log('Client disconnected');
  });
});

server.listen(3000, () => {
  console.log('Server started');
});

setInterval(() => {
  const client = net.connect(3000, () => {
    console.log('Connected to server');

    client.write('Hello server!');
    client.end();
  });
}, 1000);
