WebSocket读取字符串

Question

我知道所有内容都在websocket中作为字符串传递，但我有这两个函数：

function read_string(id)
{
    if (recvpos[id][recvbufi[id]] >= recvsize[id][recvbufi[id]])
        recvbufi[id]++;
    if (recvbufi[id] >= recvbuf[id].length)
        return "";
    var str = new String("");
    while(1)
    {
        var buf = new Uint8Array(recvbuf[id][recvbufi[id]], recvpos[id][recvbufi[id]]+2, 1);
        recvpos[id][recvbufi[id]] += 1;
        if (buf[0] == 0)
            return str;
        str += String.fromCharCode(buf[0]);
    }
}

function recv(id)
{
    if (sockets[id].readyState == 2 || sockets[id].readyState == 3)
        return 0;
    if (recvoncesize[id].length == 0 || sockets[id].readyState == 0)
        return -1;
    return recvoncesize[id].pop();
}

我在C＃控制台应用程序上使用Fleck连接并且所有事件都能正常工作，连接，断开连接，甚至将数据发送到服务器，但服务器回复这些功能都不起作用，即使recv返回-1断开连接，因为它不会返回消息的大小。

提前致谢。

编辑：这是连接过程的外观：

function connect(serverip, serverport)
{
    if (getBrowser() == 2)
        sockets.push(new MozWebSocket("ws://"+serverip+":"+serverport));    
    else
        sockets.push(new WebSocket("ws://"+serverip+":"+serverport));
    var id = sockets.length - 1;
    recvbuf[id] = new Array();
    recvbufi[id] = 0;
    recvsize[id] = new Array();
    recvoncesize[id] = new Array();
    recvpos[id] = new Array();
    sendbuf[id] = new ArrayBuffer(65535);
    sendsize[id] = 0;
    if (getBrowser() == 1)
        sockets[id].binaryType = "arraybuffer";

    sockets[id].onmessage = function(event)
    {
        if (getBrowser() == 1)
            rbuf = event.data;
        if (getBrowser() == 2)
            rbuf = Base64ToArrayBuffer(event.data); 
        var buf = new Uint8Array(rbuf, 0, 2);
        var wb = new Uint8Array(buf).buffer;
        var word = new Uint16Array(wb);
        recvbuf[id].push(rbuf);
        recvsize[id].push(word[0]);
        recvoncesize[id].push(word[0]);
        recvpos[id].push(0);
    }
    return id;
}
