node.js 模拟tcp-log-server
const net = require('net');
const {inspect} = require("util");
// Create a server instance
const server = net.createServer((socket) => {
socket.on('data', (data) => {
// 将数据转换为字符串，并以JSON格式输出
const dataString = data.toString('utf8');
console.log("Received data:", inspect(JSON.parse(dataString), false, null, true));
});
socket.on('end', () => {
});
});
// Error callback
server.on('error', (err) => {
console.error('Server error:', err);
});
// Listening callback
server.listen(9999, '127.0.0.1', () => {
console.log('Server is listening on 127.0.0.1:9999');
