Question

我正在尝试为我的UWP Windows 10应用程序开发一个Web插槽服务器应用程序。

这是我的代码：

class Server
{
    public  async void Start()
    {
        MessageWebSocket webSock = new MessageWebSocket();

        //In this case we will be sending/receiving a string so we need to set the MessageType to Utf8.
        webSock.Control.MessageType = SocketMessageType.Utf8;

        //Add the MessageReceived event handler.
        webSock.MessageReceived += WebSock_MessageReceived;

        //Add the Closed event handler.
        webSock.Closed += WebSock_Closed;

        Uri serverUri = new Uri("ws://127.0.0.1/motion");

        try
        {
            //Connect to the server.
            await webSock.ConnectAsync(serverUri);

            //Send a message to the server.
            await WebSock_SendMessage(webSock, "Hello, world!");
        }
        catch (Exception ex)
        {
            //Add code here to handle any exceptions
        }

    }

    //The MessageReceived event handler.
    private void WebSock_MessageReceived(MessageWebSocket sender, MessageWebSocketMessageReceivedEventArgs args)
    {
        DataReader messageReader = args.GetDataReader();
        messageReader.UnicodeEncoding = Windows.Storage.Streams.UnicodeEncoding.Utf8;
        string messageString = messageReader.ReadString(messageReader.UnconsumedBufferLength);

        //Add code here to do something with the string that is received.
    }


    //The Closed event handler
    private void WebSock_Closed(IWebSocket sender, WebSocketClosedEventArgs args)
    {
        //Add code here to do something when the connection is closed locally or by the server
    }

    //Send a message to the server.
    private async Task WebSock_SendMessage(MessageWebSocket webSock, string message)
    {
        DataWriter messageWriter = new DataWriter(webSock.OutputStream);
        messageWriter.WriteString(message);
        await messageWriter.StoreAsync();
    }
}

这里错误： 等待webSock.ConnectAsync（serverUri）;

出现此错误：

未找到（404）。（HRESULT的例外情况：0x80190194）

Answer 1

我没有任何个人经验，但您可能想尝试IotWeb HTTP Server。它似乎是一个便携式嵌入式HTTP和Web套接字服务器，也支持UWP，可以在Windows应用商店和Windows 10 IoT核心应用程序中运行。

从其repository来看，它相当新颖，并不完全成熟，也没有大量的文件或样本。但是可以使用NuGet package。

不幸的是，我还没有找到任何其他选择。

代码

await webSock.ConnectAsync(serverUri);

尝试连接到ws：//127.0.0.1/motion的现有服务器，不要在此地址上部署服务器。

您可以在以下链接中查找构建c＃WebSocket服务器的方法：
