我正在尝试用C#创建一个WebSocketServer。一般来说它工作正常,但我在解码过程中遇到问题。
这是我的解码功能:
public static byte[] EncodeMessageToSend(string message)
{
byte[] response;
byte[] bytesRaw = Encoding.UTF8.GetBytes(message);
byte[] frame = new byte[10];
Int32 indexStartRawData = -1;
Int32 length = bytesRaw.Length;
frame[0] = (byte)129;
if (length <= 125)
{
frame[1] = (byte)length;
indexStartRawData = 2;
}
else if (length >= 126 && length <= 65535)
{
frame[1] = (byte)126;
frame[2] = (byte)((length >> 8) & 255);
frame[3] = (byte)(length & 255);
indexStartRawData = 4;
}
else
{
frame[1] = (byte)127;
frame[2] = (byte)((length >> 56) & 255);
frame[3] = (byte)((length >> 48) & 255);
frame[4] = (byte)((length >> 40) & 255);
frame[5] = (byte)((length >> 32) & 255);
frame[6] = (byte)((length >> 24) & 255);
frame[7] = (byte)((length >> 16) & 255);
frame[8] = (byte)((length >> 8) & 255);
frame[9] = (byte)(length & 255);
indexStartRawData = 10;
}
response = new byte[indexStartRawData + length];
Int32 i, reponseIdx = 0;
//Add the frame bytes to the reponse
for (i = 0; i < indexStartRawData; i++)
{
response[reponseIdx] = frame[i];
reponseIdx++;
}
//Add the data bytes to the response
for (i = 0; i < length; i++)
{
response[reponseIdx] = bytesRaw[i];
reponseIdx++;
}
return response;
}
我从thread
那里得到了有时候它会正确解码,但之后就会开始做一些奇怪的事情。它会附加一些问号或未定义的字符。我也尝试过其他一些解码功能,但是它们也没用。
我希望有人可以帮助我。
