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());
});

希望本文所述对大家node.js程序设计有所帮助。
