当我在瀑布对话框中使用自适应卡的输入形式时，ContinueDialogAsync不起作用 [英] ContinueDialogAsync does not work when I use the input form of adaptive-cards in the waterfall dialog

问题描述

我一直在使用EchoBot模板，最近使用了VirtualAssistant模板.在上一个模板中，提交输入表单数据没有问题，但是此模板仅通过提交输入表单数据不能与ContinueDialogAsync一起使用.我们该如何解决呢?请帮助我.

I have been using the EchoBot Template and have recently used the VirtualAssistant Template. In the previous template, there was no problem in submitting the input form data, but this template does not work with ContinueDialogAsync just by submitting the input form data. How can we solve this? Please help me.

DilaogBot，

DilaogBot,

调试时，从输入表单提交时，var result = await dc.ContinueDialogAsync ();中什么都没有发生.

When debugging, nothing happens in var result = await dc.ContinueDialogAsync (); when submitting from input form.

var dc = await _dialogs.CreateContextAsync(turnContext);

                if (turnContext.Activity.Type == ActivityTypes.Message)
                {
                    // Ensure that message is a postBack (like a submission from Adaptive Cards)
                    var channelData = JObject.Parse(dc.Context.Activity.ChannelData.ToString());
                    if (channelData.ContainsKey("postback"))
                    {
                        var postbackActivity = dc.Context.Activity;
                        // Convert the user's Adaptive Card input into the input of a Text Prompt
                        // Must be sent as a string
                        postbackActivity.Text = postbackActivity.Value.ToString();
                        await dc.Context.SendActivityAsync(postbackActivity);
                    }
                }

                if (dc.ActiveDialog != null)
                {
                    var result = await dc.ContinueDialogAsync();
                }
                else
                {
                    await dc.BeginDialogAsync(typeof(T).Name);
                }

推荐答案

您需要删除:

await dc.Context.SendActivityAsync(postbackActivity);

自动程序发送消息时，会将对话框标记为已响应，并且无法正确继续.

When the bot sends a message, it marks the dialog as having been responded to and doesn't continue appropriately.

此外，您的"//确保消息是回发邮件"代码应更像这样:

Additionally, your "//Ensure message is a PostBack" code should be more like this:

var activity = turnContext.Activity;

if (activity.Type == ActivityTypes.Message)
{
    if (string.IsNullOrWhiteSpace(activity.Text) && activity.Value != null)
    {
        activity.Text = JsonConvert.SerializeObject(activity.Value);
    }
}

我相信您是从我的旧答案中得到的代码，此后我对其进行了改进.

I believe you got that code from an old answer of mine, which I have since improved.
