我正在尝试实现一个简单的Web套接字服务器和客户端。这是我第一次查看它们,很抱歉,如果这个问题很明显。

我使用的是Chrome v15,我相信它使用的是09(版本8)协议?

我只是似乎无法使他们连接。我从浏览器收到的请求是:

GET /chat HTTP/1.1
Upgrade: websocket
Connection: Upgrade
Host: localhost:8181
Sec-WebSocket-Origin: http://localhost:51990
Sec-WebSocket-Key: JFAw5PLk45TodN2ERD1ePA==
Sec-WebSocket-Version: 8
Cookie: size=4; CP.mode=B; ASP.NET_SessionId=zzx3d3ajepwwycqjaj1nyex4; .ASPXAUTH=781D3791DC2483756B3DA9FA8E031A9BACD357EBD8FA23B7BCB8BDA6526F28F77FC798A0D4BEC4E2B166700B5C08FA60CBF588D292BFC1D050C9B034522C93ACBEF28BC6D51FDC5B40F6050F03758DA1A3E4D3F7484BC4F7DA3602A5FAFD3023C8D4D5929B69F88DB417CA6F366A83F334807818E2C07E23C0D0993F25B3C9BDE02A; name=Test


我注意到Sec-WebSocket-Protocol标头丢失了。

我发送的响应如下所示:

HTTP/1.1 101 Switching Protocols
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Accept: VAuGgaNDB/reVQpGfDF8KXeZx5o=
Sec-WebSocket-Protocol: chat


谁能告诉我我在做什么错?

编辑:我用来生成接受密钥的代码是:

public static String ComputeWebSocketHandshakeSecurityHash09(String secWebSocketKey)
        {
            const String MagicKEY = "258EAFA5-E914-47DA-95CA-C5AB0DC85B11";
            String secWebSocketAccept = String.Empty;

            // 1. Combine the request Sec-WebSocket-Key with magic key.
            String ret = secWebSocketKey + MagicKEY;

            // 2. Compute the SHA1 hash
            SHA1 sha = new SHA1CryptoServiceProvider();
            byte[] sha1Hash = sha.ComputeHash(Encoding.UTF8.GetBytes(ret));

            // 3. Base64 encode the hash
            secWebSocketAccept = Convert.ToBase64String(sha1Hash);

            return secWebSocketAccept;
        }


编辑:这是响应代码:

        StringBuilder mResponse = new StringBuilder();
        mResponse.Append("HTTP/1.1 101 Switching Protocols" + Environment.NewLine);
        mResponse.Append("Upgrade: WebSocket" + Environment.NewLine);
        mResponse.Append("Connection: Upgrade" + Environment.NewLine);
        mResponse.Append(String.Format("Sec-WebSocket-Accept: {0}", ComputeWebSocketHandshakeSecurityHash09(secKey)) + Environment.NewLine);


        // Build the response for the client
        byte[] HandshakeText = Encoding.UTF8.GetBytes(mResponse.ToString());

        logger.Log("");
        logger.Log("Sending handshake ...");

        ConnectionSocket.BeginSend(HandshakeText, 0, HandshakeText.Length, 0, HandshakeFinished, null);

最佳答案

我设法建立连接,但发送邮件时无法解码。看看this question.
