Question

我的服务器上有以下代码

var socket  = require( 'socket.io' );
var express = require('express');
var app     = express();
var server  = require('http').createServer(app);
var io      = socket.listen( server );
var port    = process.env.PORT || 3000;

server.listen(port, function () {
  console.log('Server listening at port %d', port);
});


io.on('connection', function (socket) {

  socket.on( 'new_count_message', function( data ) {
    io.sockets.emit( 'new_count_message', { 
    	new_count_message: data.new_count_message

    });
  });

  socket.on( 'update_count_message', function( data ) {
    io.sockets.emit( 'update_count_message', {
    	update_count_message: data.update_count_message 
    });
  });

  socket.on( 'new_message', function( data ) {
    io.sockets.emit( 'new_message', {
    	name: data.name,
    	email: data.email,
    	subject: data.subject,
    	created_at: data.created_at,
    	id: data.id
    });
  });

  
});

但是，控制台不是在控制台中显示“update_count_message”，而是记录连续的民意调查。

我该如何解决这个问题？我不想在浏览器中收到循环。

浏览器/套接字未连接到NodeJS。 NodeJS要么没有运行，要么你正在尝试连接到错误的端口 - 在你看来它似乎正在尝试连接到端口80.如果你已经在端口80上运行Apache，你就不能同时运行NodeJS和Apache在同一个端口上，除非你在httpd.conf中设置反向代理。

您可以按照此处的调试说明查看SocketIO可能对您有哪些更具描述性的错误：

您也可以在浏览器中访问此网址，并查看其尝试连接的网页：

http://localhost/socket.io/

客户端在socket.io
