用戶回覆附件時收到錯誤的文件

我的機器人提示用戶在對話框中有附件，並且假設接收用戶的圖像並將該文件的內容名稱，URL和類型保存到變量中。但是，我收到的文件不是用戶發送的文件。相反，它的檢索命名從這個鏈接「斑點」（沒有擴展名）的文件：用戶回覆附件時收到錯誤的文件

https://webchat.botframework.com/attachments/GkLhiqJcvH019mP0iGBKvo/0000052/0/blob?t=X5ICiUrhFas.dAA.RwBrAEwAaABpAHEASgBjAHYASAAwADEAOQBtAFAAMABpAEcAQgBLAHYAbwAtADAAMAAwADAAMAA1ADIA.mcEiHxuH0gE.VMcp6Yduqgc.4xT1ZTOvCX-B7A0nLto6eZNFrFi-0xSzGk5AKmA-EPE

該文件包含：

{"type":"message","from":{"id":"9n0I1ZqSrLF","name":"You"},"locale":"en-US","timestamp":"2017-02-14T21:12:32.074Z","channelData":{"clientActivityId":"1487106689866.9060198022610071.8"}}

下面是安裝提示的代碼。此提示符在對話框中：

private async Task getAttach(IDialogContext context, IAwaitable<IEnumerable<Attachment>> result) 
    { 
     IEnumerable<Attachment> list = await result; 
     Attachment attachment = list.FirstOrDefault(); 

     string filename = attachment.Name; 
     string url = attachment.ContentUrl; 
     string contentType = attachment.ContentType; 


     //Set attachmentFileNames 
     if (attachmentFileNames == null) 
     { 
      attachmentFileNames = ""; 
     } 

     attachmentFileNames += contentType; 
     attachmentFileNames += ","; 
     numberOfFiles++; 

     //Set attachmentFileURLs 
     if (attachmentFileURLs == null) 
     { 
      attachmentFileURLs = ""; 
     } 

     attachmentFileURLs += url; 
     attachmentFileURLs += ","; 

     attachmentHasBeenAdded = true; 
     await FirstMessageReceivedAsync(context, result); 

    }

這是我如何處理消息控制器中的附件。這是郵政工作中：

ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl)); 

      if (activity.Attachments != null && activity.Attachments.Any()) 
      { 
       hasaAttachment = true; 
       var attachment = activity.Attachments.First(); 
       using (HttpClient httpClient = new HttpClient()) 
       { 
        // Skype & MS Teams attachment URLs are secured by a JwtToken, so we need to pass the token from our bot. 
        if ((activity.ChannelId.Equals("skype", StringComparison.InvariantCultureIgnoreCase) || activity.ChannelId.Equals("msteams", StringComparison.InvariantCultureIgnoreCase)) 
         && new Uri(attachment.ContentUrl).Host.EndsWith("skype.com")) 
        { 
         var token = await new MicrosoftAppCredentials().GetTokenAsync(); 
         httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token); 
        } 

        var responseMessage = await httpClient.GetAsync(attachment.ContentUrl); 

        var contentLenghtBytes = responseMessage.Content.Headers.ContentLength; 

        Activity reply = activity.CreateReply($"Attachment of {attachment.ContentType} type and size of {contentLenghtBytes} bytes received. URL: {attachment.ContentUrl}"); 

        await connector.Conversations.ReplyToActivityAsync(reply); 
       } 
      }

我下面這個例子： Receive Attachment Bot Sample

在模擬器中是否能夠正常工作，但在Azure上發佈的版本沒有。代碼與示例非常相似，所以我不明白爲什麼bot沒有檢測到用戶的文件。如何收到正確的文件（用戶回覆的文件）？

附件將在元素1之後。例如。

Attachment attachment = list.ElementAt(1);

的網上聊天（也許其他平臺）有一個奇怪的怪癖（二）在IEnumerable的「結果」開始提示，並從用戶獲取附件時增加了一個blob文件。

private async Task getAttach(IDialogContext context, IAwaitable<IEnumerable<Attachment>> result) 
{...}
