我遇到了一个大问题。 我正在尝试在c#套接字和HTML5 WebSocket
之间建立连接服务器代码

SocketType.Stream, ProtocolType.IP);

static void Main(string[] args)
{
serverSocket.Bind(new IPEndPoint(IPAddress.Any, 8080));
serverSocket.Listen(128);
serverSocket.BeginAccept(null, 0, OnAccept, null);
Console.Read();
}
private static void OnAccept(IAsyncResult result)
{
byte[] buffer = new byte[1024];
try
{
Socket client = null;
string headerResponse = "";
string testMessage = "Hello World!";
if (serverSocket != null && serverSocket.IsBound)
{
client = serverSocket.EndAccept(result);
var i = client.Receive(buffer);
headerResponse = (System.Text.Encoding.UTF8.GetString(buffer)).Substring(0,i);
// write received data to the console
Console.WriteLine(headerResponse);
}
if (client != null)
{
/* Handshaking and managing ClientSocket */
var key = headerResponse.Replace("ey:", "`")
.Split('`')[1]
.Replace("\r", "").Split('\n')[0]
.Trim();
var test1 = AcceptKey(ref key);
var newLine = "\r\n";
var response = "HTTP/1.1 101 Switching Protocols" + newLine
+ "Upgrade: websocket" + newLine
+ "Connection: Upgrade" + newLine
+ "Sec-WebSocket-Accept: " + test1 + newLine + newLine
//+ "Sec-WebSocket-Protocol: chat, superchat" + newLine

;
client.Send(System.Text.Encoding.UTF8.GetBytes(response));
var i = client.Receive(buffer); // wait for client to send a message
Console.WriteLine(Convert.ToBase64String(buffer).Substring(0, i));
Console.WriteLine(Convert.ToString(Convert.ToBase64String(buffer).Substring(0, i)));
Console.WriteLine(i.ToString());
Send(client, Encoding.UTF8.GetBytes(testMessage), 0, (testMessage).Length , 10000);
}
}
catch (SocketException exception)
{
throw exception;

byte[] hashBytes = ComputeHash(longKey);
return Convert.ToBase64String(hashBytes);
}
static SHA1 sha1 = SHA1CryptoServiceProvider.Create();
private static byte[] ComputeHash(string str)
{
return sha1.ComputeHash(System.Text.Encoding.ASCII.GetBytes(str));
}
public static void Send(Socket socket, byte[] buffer, int offset, int size, int timeout)
{
int startTickCount = Environment.TickCount;
int sent = 0; // how many bytes is already sent
do
{
if (Environment.TickCount > startTickCount + timeout)
throw new Exception("Timeout.");
try
{
sent += socket.Send(buffer, offset + sent, size - sent, SocketFlags.None);
}
catch (SocketException ex)
{
if (ex.SocketErrorCode == SocketError.WouldBlock ||
ex.SocketErrorCode == SocketError.IOPending ||
ex.SocketErrorCode == SocketError.NoBufferSpaceAvailable)
{
// socket buffer is probably full, wait and try again
Thread.Sleep(30);
}
else
throw ex; // any serious error occurr
}
} while (sent < size);
}
}
}
当我尝试发送消息时string testMessage = "Hello World!";
客户端给我错误,给出的错误代码是1006。
我搜索了StackOverFlow和一些论坛,但我找不到我需要的东西。
希望有人可以帮助我。
问候,50特别
