(代码都是放在oschina的git kingsaslib)

private function readResponse():void
{
while (sockets.bytesAvailable >= 4)
{
if (_headLen <= 0)
{
_headLen=sockets.readInt();
}

//包不够,返回继续等待
if (sockets.bytesAvailable < _headLen)
{
return;
}
var data:ByteArray=new ByteArray();
//         data.clear();
sockets.readBytes(data, 0, _headLen);
_headLen=0;
parse(data);
}

}
