我正在尝试在node.js中通过IPv6接收多播数据报.我在IPv4(udp4)上完全相同的方式没有问题,但尝试为udp6做同样的事情让我在socket.addMembership调用时出现EINVAL错误.这是我的代码:

var dgram = require('dgram');
var server = dgram.createSocket('udp6');

var PORT = 12345;
var MULTICAST_ADDRESS = 'ff7e:230::1234';

server.on('message', function (message, remote) {
    console.log('Message from: ' + remote.address + ':' + remote.port +' - ' + message);
});

server.on('listening', function () {
  var address = server.address();
  console.log('UDP listening on ' + address.address + ":" + address.port);
  server.addMembership(MULTICAST_ADDRESS);
});

server.bind(PORT);

这导致:

    Error: addMembership EINVAL
