无法从Microsoft网络聊天机器人框架在浏览器的新选项卡中导航pdf

问题描述

我无法通过在Web聊天机器人框架中使用Attachment传递URL来在浏览器的新标签页中打开pdf。我的代码段如下。

Attachment attachment = new Attachment();
attachment.ContentType = "application/pdf";
attachment.ContentUrl = DocUrl;
attachment.Name = "Name";
var response = helper.CreateResponseWithSuggestions(valueDataState.suggessionReply,attachment);
await turnContext.SendActivityAsync(response).ConfigureAwait(false);

-----在助手中------

public Activity CreateResponseWithSuggestions(Activity SuggestionsActivity,Attachment attachment)
{
     var response = SuggestionsActivity;
     response.Attachments = new List<Attachment>() { attachment };
     return response;
}
