将图像上传到Skype BOT

我有一个使用Microsoft Bot Framework开发的bot，并在Debug中正确运行

在Skype上安装后，上传图像后我有这样的链接

https://df-apis.skype.com/v2/attachments/0-eus-d4-7e19a097c62f5fc21dd53eabfa19d85e/views/original 

代码很简单，没有skype运行

 if ((activity.Attachments != null) && (activity.Attachments.Count > 0)) { analysisResult = await AnalyzeUrl(activity.Attachments[0].ContentUrl); } ........ 

我如何找到我发送的图片？

根据此评论 ，要获取附件，GET请求应包含bot的JwtToken作为授权标头：

 var attachment = activity.Attachments?.FirstOrDefault(); if (attachment?.ContentUrl != null) { using (var connectorClient = new ConnectorClient(new Uri(activity.ServiceUrl))) { var token = await (connectorClient.Credentials as MicrosoftAppCredentials).GetTokenAsync(); var uri = new Uri(attachment.ContentUrl); using (var httpClient = new HttpClient()) { if (uri.Host.EndsWith("skype.com") && uri.Scheme == Uri.UriSchemeHttps) { httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token); httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/octet-stream")); } else { httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(attachment.ContentType)); } var attachmentData = await httpClient.GetByteArrayAsync(uri); analysisResult = await AnalyzeUrl(attachmentData); } } } 

这意味着您必须更改AnalyzeUrl以接受图像数据而不是URL。 我相信您正在使用的CognitiveServices能够接受图像数据。
