【问题描述】:
现在我正在研究 Websockets,我是新手,我终于可以发送 126 字节的消息,但我需要发送更长的消息,但是当我尝试自动关闭连接时,我的代码是:
public void sendMessage(Stream stream, string message)
{
try
{
List<byte> lb = new List<byte>();
string aux = message;
bool flagStart = false;
int size;
while (message.Length > _maxLengthMessage)
{
lb = new List<byte>();
// I cut the mesasge in smaller pieces to send
message = aux.Substring(0, _maxLengthMessage);
aux = aux.Substring(_maxLengthMessage);
if (!flagStart)
{
// In doc of Websockets i sign this piece: not the end, text
lb.Add(0x01);
flagStart = !flagStart;
}
else
{
// In doc of Websockets i sign this piece: not the end, continuation
lb.Add(0x00);
}
size = message.Length;
lb.Add((byte)size);
lb.AddRange(Encoding.UTF8.GetBytes(message));
stream.Write(lb.ToArray(), 0, size + 2);
}
lb = new List<byte>();
if (!flagStart)
{
// If is this the only message we mark with: end of message, text
lb.Add(0x81);
flagStart = !flagStart;
}
else
{
//else Is the end of the message but is the continuation frame
lb.Add(0x80);
}
size = aux.Length;
lb.Add((byte)size);
lb.AddRange(Encoding.UTF8.GetBytes(aux));
//lb.AddRange(Encoding.UTF8.GetBytes(i.ToString()));
stream.Write(lb.ToArray(), 0, size+2);
}
catch (Exception ex)
{
throw ex;
}
}
有些答案说“转到 WebSocket 协议”,但它对我不起作用。
