c# - 在 .net c# 中使用 ssl Stream 从 Tcp.Client.Socket 发送数据

Question

我尝试读取一个 xml 文件并使用 sslStream 发送到服务器。 在发送到服务器之前，我必须登录并在成功授权后我必须发送文件数据。到fileSize大约是300kb。 我可以让 sycessfull 登录，但问题是服务器似乎没有收到我发送的数据。这是代码 method1:我成功登录(我收到 ok 但似乎我无法发送 xml 文件的内容)

TcpClient sendClient = new TcpClient(serverName, port);
        SslStream sendStream = new SslStream(sendClient.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
        sendStream.AuthenticateAsClient(serverName, null, SslProtocols.Ssl2, true);

        sendStream.Write(Encoding.UTF8.GetBytes("Login\r\n" + username + "\r\n" + password + "\r\n"));
        sendStream.Flush();
        int bytes = -1;
        byte[] buffer = new byte[2048];

        bytes = sendStream.Read(buffer, 0, buffer.Length);

        string response = Encoding.UTF8.GetString(buffer, 0, bytes);

        if (response.Trim() == "OK")
        {
            MessageBox.Show("Connected");
            byte[] b1 = File.ReadAllBytes(filePath);
            sendStream.Write(Encoding.UTF8.GetBytes("Send\r\n"));
            sendStream.Write(Encoding.UTF8.GetBytes(fileName+"\r\n"));
            sendStream.Write(b1, 0, b1.Length);
            sendStream.Flush();
            sendStream.Write(Encoding.UTF8.GetBytes("Quit\r\n"));
            sendStream.Flush();
            sendClient.Close();
        }

这是使用 streamWriter 的第二种方法

TcpClient sendClient = new TcpClient(serverName, port);
        SslStream sendStream = new SslStream(sendClient.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
        sendStream.AuthenticateAsClient(serverName, null, SslProtocols.Ssl2, true);

        StreamWriter writer = new StreamWriter(sendStream);
        writer.WriteLine("Login");
        writer.WriteLine(username);
        writer.WriteLine(password);
        writer.Flush();
        StreamReader reader = new StreamReader(sendStream);
        string response = reader.ReadLine();
        if (response.Trim() == "OK")
        {
            MessageBox.Show("succesfull connect");

            string allText = File.ReadAllText(filePath,Encoding.Default);
            writer.WriteLine("Send");
            writer.WriteLine(fileName);
            writer.WriteLine(allText);
            sendClient.Close();
        }

好的，一种解决方案是将所有命令写成一个字节数组，然后将它们复制到一个更大的数组中。诀窍是将 dataSize 添加为双字节序数
