我已在 Microsoft 团队中发布了我的机器人。现在我想包含一个功能,用户可以将文件作为附件上传,机器人会将其上传到 blob 存储中,如何在机器人框架中处理此问题?
用户发送的附件将最终出现在Attachments
IMessageActivity 的集合。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传到 Blob 存储或您想要使用的任何其他存储。
Here https://github.com/Microsoft/BotBuilder-Samples/tree/master/CSharp/core-ReceiveAttachment是一个 C# 示例,显示如何访问和下载用户发送的附件。添加以下代码供您参考:
public virtual async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> 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);
}
