Question

我无法从机器人向Skype中的用户发送文件附件。我正在使用bot builder版本3.5.0。

以下是我的代码。

ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));
Activity reply = activity.CreateReply("blah");
reply.Attachments = new List();
Attachment attach = new Attachment();

attach.ContentType = "application/pdf";
// I can browse the below URL in browser and access the PDF
attach.ContentUrl = "https://test.azurewebsites.net/Image/Test.pdf";
attach.Name = "Test.pdf";
attach.Content = "Test";
attach.ThumbnailUrl = attach.ContentUrl;
reply.Attachments.Add(attach);
await connector.Conversations.ReplyToActivityAsync(reply);

除了迫切需要升级您的botbuilder版本之外，还有一个sample。请参阅它以获得进一步的指导。它位于botbuilder-samples仓库。在样本中，他们构建的附件非常类似于你：

private static Attachment GetInternetAttachment()
{
    return new Attachment
    {
        Name = "BotFrameworkOverview.png",
        ContentType = "image/png",
        ContentUrl = "https://docs.microsoft.com/en-us/bot-framework/media/how-it-works/architecture-resize.png"
    };
}

所以这很可能是由您正在使用的非常过时的botbuilder版本引起的
