Node.js服务器无法正常工作

Question

我正在尝试进行简单的文本聊天。服务器启动和工作。我的客户端连接正常，它显示在控制台的日志中：

C:\inetpub\wwwroot\3>node app.js 
    info - socket.io started 
Socket-Chat listening on port 9202.. Go to http://<this-host>:9202 
    debug - client authorized 
    info - handshake authorized 3088178251169496669 
    debug - setting request GET /socket.io/1/flashsocket/3088178251169496669 
    debug - set heartbeat interval for client 3088178251169496669 
    debug - client authorized for 
    debug - websocket writing 1:: 
    debug - websocket received data packet 3:::USERNAME:----------cvx 
    debug - websocket received data packet 3:::xcvcx 

但是不要为其他聊天客户端广播。

我试图插入server`s码输出到控制台进行测试不同的部分，但只显示在某些地方（以代码“DISPLAY”），在其他未显示（以代码“NO显示”）。 服务器代码app.js：这个问题的

var io = require('socket.io'), 
    http = require('http'); 

var fs = require('fs'), 
    util = require('util'); 

var url = require('url'), 
    path = require('path'), 
    mime = require('mime'); 

function findType(uri) { 
    var ext = uri.match(/\.\w+$/gi); 
    if (ext && ext.length > 0) { 
    ext = ext[0].split(".")[1].toLowerCase(); 
    return mime.lookup(ext); 
    } 
    return undefined; 
} 

function sendError(code, response) { 
    response.writeHead(code); 
    response.end(); 
    return; 
} 
console.log("DISPLAY"); 
var app = http.createServer(function(request, response) { 
    var uri = url.parse(request.url).pathname; 
    console.log("NO DISPLAY"); 
    if (uri === '/') { 
    uri = '/index.html'; 
    } else if (uri === '/app.js') { 
    sendError(404, response); 
    return; 
    } 
    var _file = path.join(process.cwd(), uri); 
console.log("NO DISPLAY"); 
    path.exists(_file, function(exists) { 
    if (!exists) { 
     sendError(404, response); 
    } else { 
     fs.stat(_file, function(err, stat) { 
     var file = __dirname + uri, 
      type = findType(uri), 
      size = stat.size; 
     if (!type) { 
      sendError(500, response); 
     } 
     response.writeHead(200, {'Content-Type':type, 'Content-Length':size}); 
     var rs = fs.createReadStream(file); 
     console.log("NO DISPLAY"); 
     util.pump(rs, response, function(err) { 
      if (err) { 
      console.log("ReadStream, WriteStream error for util.pump"); 
      response.end(); 
      } 
     }); 
     }); 
    } 
    }); 

}); 

// Only listen on $ node app.js 

if (!module.parent) { 
    app.listen(9202); 
    console.log("Socket-Chat listening on port 9202.. Go to http://<this-host>:9202"); 
} 

var socket = io.listen(app, {transports:['websocket', 'flashsocket', 'xhr-polling']}), 

    buffer = [], 
    MAXBUF = 1024, 
    json = JSON.stringify; 

var clients = []; 
clients.usernames = function(client) { 
    console.log("NO DISPLAY"); 
    return client.username; 
} 

socket.on('connection', function(client) { 
console.log("NO DISPLAY"); 

    client.on('message', function(data) { 
    if ((/^(USERNAME:).*$/ig).test(data)) { 
     var parts = data.split(":"); 
     var username = parts[1]; 

     if (!username || username == '') { 
     client.send({announcement:"You must specify a username. Please reload the app."}); 
     return; 
     } 

     var usernames = clients.map(clients.usernames); 
     if (usernames.indexOf(username) >= 0) { 
     client.send({announcement:"Username in use"}); 
     return; 
     } 

     client.username = username; 

     client.broadcast.json.send({announcement:client.username+' joined'}); 
     console.log(client.sessionId + " = " + client.username); 
     client.send({messages:buffer}); 
     client.send({userlist:usernames}); 
     client.send({announcement:"Connected! Hello, " + username + "!"}); 

     clients.push(client); 
     return; 
    } 

    if (!client.username) { 
     client.send({announcement:"You must specify a username. Please reload the app."}); 
     return; 
    } 

    var message = {'user':client.sessionId, 'username':client.username, 'message':data}; 
    buffer.push(message); 
    if (buffer.length > MAXBUF) { 
     buffer.shift(); 
    } 
    client.broadcast.json.send(message); 
    }); 

    client.on('disconnect', function() { 
    if (client.username) { 
     client.broadcast({announcement:(client.username)+' left chat'}); 
    } 
    var pos = clients.indexOf(client); 
    if (pos >= 0) { 
     clients.splice(pos, 1); 
    } 
    }); 
}); 

提示可能的原因，请。 服务器安装在Windows 7（IIS7）

我已经回答了有关socket.io一些类似的问题，尽量避免复制和粘贴相同的东西:) - CF info - unhandled socket.io url

本质上出现了微小的变化在API中，请尝试更改socket.on('connection'至socket.sockets.on('connection'

希望有所帮助。
