有没有办法接受文件作为机器人框架中的附件？

我在微软团队上发布了我的机器人。 现在我想要包含一个function，用户可以将文件作为附件上传，bot会将其上传到blob存储，如何在bot框架中处理？

Answer 1

用户发送的附件将最终出现在IMessageActivity的Attachments集合中。 在那里，您将找到用户发送的附件的URL。

然后，您必须下载附件并添加逻辑以将其上载到Blob存储或您要使用的任何其他存储。

这是一个C＃示例，显示如何访问和下载用户发送的附件。 添加了以下代码供您参考：

 public virtual async Task MessageReceivedAsync(IDialogContext context, IAwaitable argument) { var message = await argument; if (message.Attachments != null && message.Attachments.Any()) { var attachment = message.Attachments.First(); using (HttpClient httpClient = new HttpClient()) { // Skype attachment URLs are secured by a JwtToken, so we need to pass the token from our bot. if (message.ChannelId.Equals("skype", 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; await context.PostAsync($"Attachment of {attachment.ContentType} type and size of {contentLenghtBytes} bytes received."); } } else { await context.PostAsync("Hi there! I'm a bot created to show you how I can receive message attachments, but no attachment was sent to me. Please, try again sending a new message including an attachment."); } context.Wait(this.MessageReceivedAsync); }
