UDP/数据报套接字

\UDP/datagram sockets

源代码: lib/dgram.js

node:dgram 模块提供了 UDP 数据报套接字的实现。

\The node:dgram module provides an implementation of UDP datagram sockets.

import dgram from 'node:dgram';
const server = dgram.createSocket('udp4');
server.on('error', (err) => {
 console.error(`server error:\n${err.stack}`);
 server.close();
});
server.on('message', (msg, rinfo) => {
 console.log(`server got: ${msg} from ${rinfo.address}:${rinfo.port}`);
});
server.on('listening', () => {
 const address = server.address();
 console.log(`server listening ${address.address}:${address.port}`);
});
server.bind(41234);
// Prints: server listening 0.0.0.0:41234const dgram = require('node:dgram');
const server = dgram.createSocket('udp4');
server.on('error', (err) => {
 console.error(`server error:\n${err.stack}`);
 server.close();
});
server.on('message', (msg, rinfo) => {
 console.log(`server got: ${msg} from ${rinfo.address}:${rinfo.port}`);
});
server.on('listening', () => {
 const address = server.address();
 console.log(`server listening ${address.address}:${address.port}`);
});
server.bind(41234);
// Prints: server listening 0.0.0.0:41234拷贝
