Bot Framework .Net Core从IFrame获取字符串变量

Question

问题是使用.Net Core通过Bot Framework创建Bot应用程序。在.Net Framework中，我使用API​​来创建Bot App。在初始方法我传递字符串参数并从IFrame Url获取此值，但在.Net Core中我使用的是OnTurnAsync方法，并且无法覆盖此方法以将字符串参数作为“userName”传递。我在下面的.Net核心和.Net框架初始方法之间进行共享。

我通过IFrame调用bot应用程序，如; https://webchat.botframework.com/...&userName=test'style =“width：600px; height：600px;”>

那么如何将参数传递给OnTurnAsync方法呢？

.Net框架

   public async Task<HttpResponseMessage> Post([FromBody]Activity activity, string userName)
    {
        if (activity.Type == ActivityTypes.Message)
        {                
            var keyword = activity.Text.ToLower().ToEnglish();
            var responseAttachment = KeywordHelper.GetAttachmentResult(keyword);
            if (responseAttachment != null)
            {
                var answer = ((HeroCard)responseAttachment.Content).Title.ToString();
                conversation.Response = answer;
                this.conversationService.InsertToConversation(conversation);
                var connector = new ConnectorClient(new Uri(activity.ServiceUrl));
                var reply = activity.CreateReply();
                reply.Attachments.Add(responseAttachment);
                await connector.Conversations.ReplyToActivityAsync(reply);

                activity.Type = ActivityTypes.Message;
            }
        }
    }

.Net核心

        public async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))
    {
            if (turnContext.Activity.Type == ActivityTypes.Message)
            {
                var userName = "userName";

                var keyword = turnContext.Activity.Text.ToLower().ToEnglish();
                var responseAttachment = KeywordHelper.GetAttachmentResult(keyword);

                if (responseAttachment != null)
                {
                    var answer = ((HeroCard)responseAttachment.Content).Title.ToString();
                    conversation.Response = answer;
                    this.conversationService.InsertToConversation(conversation);
                    var connector = new ConnectorClient(new Uri(turnContext.Activity.ServiceUrl));


                    var reply = turnContext.Activity.CreateReply();
                }

            }
    }

你仍然可以使用带有BotBuilder V4的Web Api控制器，如下例所示：https://github.com/Microsoft/BotBuilder-Samples/blob/samples-work-in-progress/samples/csharp_dotnetcore/13.core-bot/Controllers/BotController.cs

[Route("api/messages")]
[ApiController]
public class BotController : ControllerBase
{
    private readonly IBotFrameworkHttpAdapter Adapter;
    private readonly IBot Bot;

    public BotController(IBotFrameworkHttpAdapter adapter, IBot bot)
    {
        Adapter = adapter;
        Bot = bot;
    }

    [HttpPost]
    public async Task PostAsync()
    {
        // Delegate the processing of the HTTP POST to the adapter.
        // The adapter will invoke the bot.
        await Adapter.ProcessAsync(Request, Response, Bot);
    }
}

但是，如果您将用户标识和用户名作为查询字符串参数传递给WebChat iframe，那么您可以从activity.From.Name检索用户名
