ios - NodeJs：从模块向房间发送数据

Question

在 Patrick Robert 的回答之后，我试图在我的模块的特定房间中发出一条消息如何将 socket.io 导出到 nodejs 中的其他模块中？.

io.js

var sio = require('socket.io');
var io = null;

exports.io = function () {
  return io;
};

exports.initialize = function(server) {
  return io = sio(server);
};

服务器.js

const server = https.createServer(SSLoptions, app).listen(8080);
const options = {};

var io = require("./io").initialize(server, options);

io.sockets.on('connection', function(socket) {
    socket.on('create', function(room) {
      socket.join(room);
    });
});

var check_offer = require('./check_offer.js');

function sendDataIo(data) {
    io.to(data.room_name).emit("message",data);
    //everything is good
}

模块.js

ioreq = require('./io')

ioreq.io().on('connection', function(socket) {
    var room_name = 2;
    socket.join(room_name);
    socket.to(room_name).emit("test",'This is a Test'); //This is working but I need to do it inside a function.
});

function sendDataFromModule(data) { // This function don't do anything at all !
     
ioreq.io().on('connection', function(socket) {
    var room_name = 2;
    socket.join(room_name);
    socket.to(room_name).emit("test",'This is a Test');
});

}
