WebSocket读取字符串

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来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，但是当服务器回复这两个函数都不起作用时，即使recv在断开连接时返回-1，因为它它应该不返回消息的大小。

提前致谢。

编辑：这是连接过程的样子：

 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; }
