控制字符的Socket.IO问题

Question

我正在实现一个使用websockets和通过Telnet访问的控制台的应用程序.通过websockets建立的连接与控制台之间存在通信.我遇到了一个奇怪的问题:

• 如果我在控制台中输入某些内容时将字符串常量发送到已建立的套接字,则它可以正常工作.
• 如果我发送一个从控制台范围收到的字符串似乎打开一个新的套接字(不确定),因为在调试日志中我看到它,并在浏览器端(websockets)它提醒我一个新的连接.
• 如果我发送一个本地字符串(而不是从另一个范围收到的字符串),它将被正确发送.(注释行:client.send(message))

我在这里分享nodeJS代码,考虑到这现在是一个测试应用程序所以它假设只有一个套接字和websockets连接:

// Sample based on: http://elegantcode.com/2011/05/04/taking-baby-steps-with-node-js-websockets/
// Changed for sockets.io 6.x => 7.x


var events = require('events');
var eventEmitter = new events.EventEmitter();

var http = require('http');
var socketIO = require('socket.io');
var static = require('node-static');

var port = 2000;

var clientFiles = new static.Server('./client');

var httpServer = http.createServer(
    function(request, response) {
        request.addListener('end', function() { 
            clientFiles.serve(request, response);
       });
    })

httpServer.listen(port);
console.log("Server running at port: " + port);

var io = require('socket.io').listen(httpServer);

var webSocket = io.sockets;

webSocket.on('connection', function(client) {
    client.send('Please enter a user name ...');
    var userName;

    eventEmitter.on('someOccurence', function(message) {
        console.log("Received: " + message);
        client.send('Line Received');
        var s = 'popo';
        client.send(s);
        //client.send(message);
    });


    client.on('message', function(message) {
        console.log(message);

        if(!userName) {
            userName = message;
            client.broadcast.send(message + ' has entered the zone.');
            return;
        }

        var broadcastMessage = userName + ': ' + message;
        client.broadcast.send(broadcastMessage);
        client.send("Repeated here: " + message);
    });

    client.on('disconnect', function() {
        var broadcastMessage = userName + ' has left the zone.';
        client.broadcast.send(broadcastMessage);
    });
});


var lines = require('lines-adapter');
var net = require('net');

var server = net.createServer(function (socket) {
    socket.write("Welcome to the Server\r\n");

    lines(socket, 'utf8')
    .on("data",
        function(line) {
            console.log("Line received: " + line);
            eventEmitter.emit('someOccurence', line);
        }
    )
    .end("end",
        function() {
            console.log("End of Stream");
        }
    );
});

server.listen(1337, "127.0.0.1");

更新:我刚刚测试了socket.io 0.8.6和nodeJS 0.4.12没有这个问题.我会在这里提出这个问题,以备将来参考.

用socket.io v0.8.6修复.应该回答/关闭此q.
