如何解决skype bot中的图像附件显示问题?

我在我的机器人skype中使用bot框架(C#SDK)。它在模拟器中工作正常,但是当我在Skype上运行它时,它不会显示图像attachemnts。 我检查了文档,但我找不到任何解决方案。我不确定这是我的问题还是在Skype上。 注意:我在我的手机上使用skype for windows 10和skype for android(不适用于其中任何一种)

以下是模拟器中附件的http响应

这是skype中的图片

以下是生成附件的方法

public Attachment ChartCard(StandardInfoData[] data)
{
    if (data != null && data.Length != 0)
    {
        string chartUrl = data[0]?.report?.url;

        Attachment attachment = new Attachment();
        attachment.ContentUrl = chartUrl;
        attachment.ContentType = "image/png";
        attachment.Name = "Chart Report";

        return attachment;
    }
    else
    {
        Attachment attachment = new Attachment();
        attachment.Content = "No Chart Report Found";
        return attachment;
    }      
}

以下是调用此方法的代码。我从我们的服务器“Human Collaborator”获取此图像并使用套接字与其进行通信。 对于套接字我正在使用“websocket-sharp”库

private async Task StandardInfoFormComplete(IDialogContext context, IAwaitable<StandardInfoForm> result)
    {
        try
        {
            var form = await result;
            eventOccured = false;
            SocketStream.ws.OnMessage += (sender, e) =>
            {
                try
                {
                    var json = e.Data;
                    StandardInfoJson response = JsonConvert.DeserializeObject<StandardInfoJson>(json);
                    var data = response.data;
                    if (data[0].result.ToLower() == "ok")
                    {
                        // For chart reports                            
                        var chartAttachment = card.ChartCard(data);
                        replyToConversation.Attachments.Add(chartAttachment);

                        context.PostAsync(replyToConversation);
                    }
                    if (data[0].result.ToLower() == "error")
                    {
                        var replyToConversation = context.MakeMessage();
                        var message = data[0]?.message;
                        replyToConversation.Text = message;
                        context.PostAsync(replyToConversation);
                    }
                }
                catch (NullReferenceException ex)
                {
                    Debug.WriteLine(ex.StackTrace);
                }

                eventOccured = true;
            };

            //builds the botRequest part of json string
            Utilities.StringBuilder.JsonStringBuilder(context, result);
            // Instantiate JSONDataObjects class
            JSONDataObjects jdo = new JSONDataObjects();
            //Create JSON string
            string output = JsonConvert.SerializeObject(jdo, Formatting.Indented);
            Debug.WriteLine("USER: \n" + output);
            //Sending the Json object to Human-Collaborator
            SocketStream.ws.Send(output);
            await context.PostAsync("Generating response.....Please Be Patient.....");
            Thread.Sleep(8000);
            if (!eventOccured)
                await context.PostAsync("Server is busy ... Please try again later");

            context.Done(true);
        }
        catch (Exception e)
        {
            string reply;
            if (e.InnerException == null)
            {
                reply = $"You quit --maybe you can finish next time!";
            }
            else
            {
                reply = "Sorry, I've had a short circuit.  Please try again.";
            }
            await context.PostAsync(reply);
        }
    }

请帮助我,我做错了什么。感谢

答案 0 :(得分:2)

我没有重播你的案例的所有代码,但我看到一件重要的事情:

else
{
    Attachment attachment = new Attachment();
    attachment.Content = "No Chart Report Found";
    return attachment;
}

在此您不应创建附件,因为您无需附加任何内容。这将导致错误,因为ContentType缺失。

您是否可以修改调用ChartCard的代码:当其参数(您的StandardInfoData[])为空时,不应调用该代码。

我无法使用您提供的代码进行更多测试,但您还应检查从Skype呼叫时Socket呼叫中的数据是否正常(例如通过输出值或任何其他方式),这将有助于你的调查

编辑:在对此答案进行了大量评论之后,看起来问题来自于无法从Skype(位于用户网络内的服务器上)访问该图像的事实
