所以我尝试使用 C# 套接字连接到服务器,但我遇到了这个错误:

System.Net.Internals.SocketExceptionFactory+ExtendedSocketException: Une tentative d'accès à un socket de manière interdite par ses autorisations d'accès a été tentée 192.168.1.17:9999

(!!抱歉不知道怎么用英文写visual studio)

这是我的代码

    Socket sock;

    public MainPage()
    {
        this.InitializeComponent();
        // Initialize MyRecognizer and Load Grammar

        connectToYanaForAll("192.168.1.17", 9999);
        sendInfoToYanaSocket(sock);
        //createGrammarFromYana(sock);
        disconnectFromYana(sock);
    }

    public void sleep(long millis) { Stopwatch stopwatch = Stopwatch.StartNew();  while (true)  { if (stopwatch.ElapsedMilliseconds >= millis) { break; } }  }

    public void connectToYanaForAll(String ip, int port)
    {
        IPAddress ipAddress = IPAddress.Parse(ip); //ipHostInfo.AddressList[0];
        IPEndPoint remoteEP = new IPEndPoint(ipAddress, port);
        // Create a TCP/IP  socket.  
        sock = new Socket(ipAddress.AddressFamily, SocketType.Stream, ProtocolType.Tcp); <-- Fail at this line
        sock.Connect(remoteEP);
    }


    public void disconnectFromYana(Socket sock)
    {
        sock.Shutdown(SocketShutdown.Both);
        sock = null;
    }

    public void sendInfoToYanaSocket(Socket sock)
    {
        String infos = "{\"action\":\"client_infos\",\"type\":\"listen\",\"version\":\"2\",\"location\":\"bureau\",\"token\":\"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\"}<EOF>";
        byte[] msg = Encoding.ASCII.GetBytes(infos);
        int bytesSent = sock.Send(msg);
        Debug.WriteLine(String.Join(bytesSent.ToString()," bytes sent!"));
    }

    public void createGrammarFromYana(Socket sock)
    {
        String infos = "{\"action\":\"GET_SPEECH_COMMANDS\"}<EOF>";
        byte[] msg = Encoding.ASCII.GetBytes(infos);
        int bytesSent = sock.Send(msg);
        Debug.WriteLine(String.Join(bytesSent.ToString(), " bytes sent!"));

        sleep(200);

        byte[] bytes = new byte[4096];
        int bytesRec = sock.Receive(bytes);
        Debug.WriteLine(String.Join("Received: ", bytesRec.ToString(), " bytes!"));
        Debug.WriteLine("Text = {0}",Encoding.ASCII.GetString(bytes, 0, bytesRec));
    }

我知道您需要管理员权限才能使用原始套接字,但我正在使用stream socket,所以我有点卡住了。(顺便说一句,我正在使用 Visual Studio 2017)我尝试过的内容:

  • 完全禁用防火墙:不工作
  • 完全禁用防病​​毒:不工作
  • 使用TcpClient client = new TcpClient();课程:不工作

所以解决方案是将该行放入 Package.appxmanifest

<Capability Name="privateNetworkClientServer" />

<Capabilities>标签中

根据谷歌翻译,错误消息说:“试图访问被其访问权限禁止的套接字的尝试是 192.168.1.17:9999”

所以看起来仍然存在权限问题。也许您的系统上运行了防火墙,只允许一些已知的传出连接?

尝试将您的套接字绑定到端点而不是连接,然后调用 Listen。希望能帮助到你
