C# HttpListener 接受untiy 上传的视频，俩端显示进度

要实现C# HttpListener接收Unity上传的视频，并且在两端显示进度，你可以按照以下步骤进行操作：

1. 在Unity中使用UnityWebRequest类来上传视频，同时在上传时通过POST方式发送进度信息。

IEnumerator UploadVideo()
{
    UnityWebRequest request = UnityWebRequest.Post(uploadURL, form);
    request.SendWebRequest();
    while (!request.isDone)
    {
        float progress = request.uploadProgress;
        // 通过POST方式发送进度信息
        UnityWebRequest progressRequest = UnityWebRequest.Post(progressURL, progressForm);
        progressRequest.SendWebRequest();
        yield return null;
    }
}

2. 在C#中使用HttpListener接收视频和进度信息。

public async Task StartListener()
{
    HttpListener listener = new HttpListener();
    listener.Prefixes.Add("http://localhost:8080/");
    listener.Start();
    while (true)
    {
        HttpListenerContext context = await listener.GetContextAsync();
        HttpListenerRequest request = context.Request;
        HttpListenerResponse response = context.Response;
        if (request.HttpMethod == "POST" && request.Url.LocalPath == "/video")
        {
            // 接收视频
            using (var stream = File.Create("video.mp4"))
            {
                await request.InputStream.CopyToAsync(stream);
            }
        }
        else if (request.HttpMethod == "POST" && request.Url.LocalPath == "/progress")
        {
            // 接收进度信息
            string progress = new StreamReader(request.InputStream).ReadToEnd();
            Console.WriteLine("Progress: " + progress);
        }
    }
}

3. 在接收进度信息的同时，可以使用WebSocket来将进度信息发送到另一个客户端。

public async Task StartWebSocket()
{
    HttpListener listener = new HttpListener();
    listener.Prefixes.Add("http://localhost:8081/");
    listener.Start();
    while (true)
    {
        HttpListenerContext context = await listener.GetContextAsync();
        HttpListenerWebSocketContext webSocketContext = await context.AcceptWebSocketAsync(subProtocol: null);
        WebSocket webSocket = webSocketContext.WebSocket;
        while (webSocket.State == WebSocketState.Open)
        {
            HttpListenerRequest request = await webSocketContext.WebSocket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);
            HttpListenerResponse response = context.Response;
            // 发送进度信息
            string progress = GetProgress();
            byte[] bytes = Encoding.UTF8.GetBytes(progress);
            await webSocket.SendAsync(new ArraySegment<byte>(bytes), WebSocketMessageType.Text, true, CancellationToken.None);
        }
    }
}

4. 在另一个客户端中使用WebSocket来接收进度信息，并且在界面上显示出来。

public async Task StartWebSocket()
{
    using (ClientWebSocket webSocket = new ClientWebSocket())
    {
        Uri serverUri = new Uri("ws://localhost:8081/");
        await webSocket.ConnectAsync(serverUri, CancellationToken.None);
        while (webSocket.State == WebSocketState.Open)
        {
            byte[] buffer = new byte[1024];
            WebSocketReceiveResult result = await webSocket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);
            if (result.MessageType == WebSocketMessageType.Text)
            {
                string progress = Encoding.UTF8.GetString(buffer, 0, result.Count);
                // 在界面上显示进度信息
                Console.WriteLine("Progress: " + progress);
            }
        }
    }
}

通过以上步骤，你就可以实现C# HttpListener接收Unity上传的视频，并且在两端显示进度了。
