laovel 5.2에서 socket.io를 사용하여 연결하는 동안 io.on이 작동하지 않습니다. io.on 함수를 연결하는 동안 문제가 발생했습니다 (실제로 좌절했습니다).

Question

나는 express, ioredis 및 socket.io를 사용하고 있습니다. redis 제대로 작동하지만 socket.io 작동하지 않습니다. it'nt working.please 도움을.

var app = require('express')(); 
var server = require('http').Server(app); 
var io = require('socket.io')(server); 
var Redis = require('ioredis'); 
var redis = new Redis(); 

//port connection 
server.listen(3000); 
console.log('server listening 3000'); 

//redis sub (working fine) 
redis.subscribe('test-channel', function() { 
    console.log('Redis: test-channel subscribed'); 
}); 

//this code is not working (stop execution) 
io.on('connection', function(socket){ 
    console.log("new client connected"); 
}); 


io.on('connection', function (socket) { 
    console.log("new client connected"); 

    redis.subscribe('message'); 
    console.log("redis start"); 

    //send message to frontend 
    redis.on("message", function(channel, message) { 
     console.log("mew message in queue "+ message + "channel"); 
     socket.emit(channel, message); 
    }); 
    //close socket 
    socket.on('disconnect', function() { 
     redis.quit(); 
     console.log('redis disconnected!'); 
    }); 

});

서버 측

var express = require('express'); 
var app = express(); 
var server = require('http').createServer(app); 
var io = require('socket.io').listen(server); // it was require('socket.io')(server); 

server.listen(3000); 

클라이언트 측

io.sockets.on('connection', function(socket){ 
    console.log("new client connected"); 
});
