Question

我正在使用来自vtortola的WebSocketListener，我遇到了一些套接字抛出错误然后自行关闭的问题。如果我一次在套接字上请求太多数据，我认为它正在发生。我正在通过1个插槽传输多个jpeg图像。所以我每秒可以获得50多个图像请求。有时它发生得比其他人快，有时根本不会。

错误： aex.message =“不能在websocket上写” aex.innerException =“写入超时。”

我在vb.net API项目中实现了这个功能，该项目通过1个单一套接字返回所有图像。对于大多数过去它的工作正常，除了这个随机错误然后关闭套接字。

错误会在try / catch中被捕获，然后自行关闭。如果我注释掉ws.close（）和ws.Dispose（），套接字仍会自行关闭。

Private Shared Async Function HandleConnectionAsync(ws As vtortola.WebSockets.WebSocket, cancellation As CancellationToken) As Task(Of Task)
    ' A request is made
    Console.WriteLine("Connection " + ws.RemoteEndpoint.Port.ToString() + " opened. " + DateTime.Now.ToString("MM/dd/yyyy HH:mm:ss"))

    Try
        While ws.IsConnected AndAlso Not cancellation.IsCancellationRequested
            msg = Await ws.ReadStringAsync(cancellation).ConfigureAwait(False)
            If msg IsNot Nothing Then
                Using messageWriterStream As WebSocketMessageWriteStream = ws.CreateMessageWriter(WebSocketMessageType.Binary)
                    image = Await GetImage()
                    If image IsNot Nothing Then
                        Await messageWriterStream.WriteAsync(image, 0, Int(image.Length), cancellation).ConfigureAwait(False)
                    End If
                End Using
            End If
        End While
    Catch aex As Exception
        ws.Close()
    Finally
        ws.Dispose()
        Console.WriteLine("Connection " + ws.RemoteEndpoint.Port.ToString() + " closed. " + DateTime.Now.ToString("MM/dd/yyyy HH:mm:ss"))
    End Try
End Function
