node.js基于dgram数据报模块创建UDP服务器和客户端(2)

const dgram = require('dgram'); const multicastAddr = '224.1.1.1'; let client = dgram.createSocket('udp4'); client.bind(6666, '0.0.0.0', function() { //将socket加入组播组中 client.addMembership(multicastAddr); }); client.on('message', function (msg, rinfo) { console.log(msg.toString()); });
