如何将对话从Formflow转发到QnaDialog

问题描述

您好，我是机器人开发的新手，我试图弄清楚如何在Formflow之后将对话转发到QnaDialog.我的表单流仅在识别出用户名之后询问用户他/她的名字，之后只想打个招呼(用户名)，因为我已经确定了用户，所以我希望以后的任何消息都已经转发到QnaDialog.我尝试一次添加一个检查器来标记问候语已经完成，但是由于只允许您进行一次对话.SendAsync现在我迷失了如何正确解决此问题的想法.

Hi Guys im new to bot development, and im trying to figure out how can i forward the conversation to a QnaDialog after formflow. My formflow simply asks the user his/her name after he/she was identified, it would simply say hi (username) afterwards what I want is that any message afterwards would be forwarded to a QnaDialog already since the user was already identified. I tried adding a checker once to flag that a greeting was done already, however since you are only allowed one Conversation.SendAsync I am now lost for ideas on how to correct this properly.

FORMFLOW

  public class ProfileForm
{
    // these are the fields that will hold the data
    // we will gather with the form
    [Prompt("What is your name? {||}")]
    public string Name;

    // This method 'builds' the form
    // This method will be called by code we will place
    // in the MakeRootDialog method of the MessagesControlller.cs file
    public static IForm<ProfileForm> BuildForm()
    {
        return new FormBuilder<ProfileForm>()
                .Message("Welcome to the profile bot!")
                .OnCompletion(async (context, profileForm) =>
                {
                    // Set BotUserData
                    context.PrivateConversationData.SetValue<bool>("ProfileComplete", true);
                    context.PrivateConversationData.SetValue<string>("Name", profileForm.Name);
                    // Tell the user that the form is complete
                    await context.PostAsync("Your profile is complete.");
                })
                .Build();
    }


}

MessageController

public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
    {
        if (activity.Type == ActivityTypes.Message)
        {
            //ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));
            //await Conversation.SendAsync(activity, () => new QnADialog());

            #region Formflow

            // Get any saved values
            StateClient sc = activity.GetStateClient();
            BotData userData = sc.BotState.GetPrivateConversationData(
                activity.ChannelId, activity.Conversation.Id, activity.From.Id);
            var boolProfileComplete = userData.GetProperty<bool>("ProfileComplete");
            if (!boolProfileComplete)
            {
                // Call our FormFlow by calling MakeRootDialog
                await Conversation.SendAsync(activity, MakeRootDialog);
            }
            else
            {
                //Check if Personalized Greeting is done
                if (userData.GetProperty<bool>("Greet"))
                {
                    //this doesnt work since their should be only one Conversation.SendAsync.

                    //ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));
                    //await Conversation.SendAsync(activity, () => new QnADialog());
                }
                else
                {
                    // Get the saved profile values
                    var Name = userData.GetProperty<string>("Name");
                    userData.SetProperty<bool>("Greet", true);
                    sc.BotState.SetPrivateConversationData(activity.ChannelId, activity.Conversation.Id,activity.From.Id, userData);
                    ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));
                    Activity replyMessage = activity.CreateReply(string.Format("Hi {0}!", Name));
                    await connector.Conversations.ReplyToActivityAsync(replyMessage);
                }
            }
            #endregion
        }
        else
        {
            HandleSystemMessage(activity);
        }
        var response = Request.CreateResponse(HttpStatusCode.OK);
        return response;
    }

推荐答案

以下是使用您的示例的示例.我做了一些小改动，但没有发现您无法找到的所有内容.一点解释:

Here is an example using your example. I made a few small changes but nothing you wouldn't be able to spot. A bit of explanation:

控制器:我清理了它.它实际上应该只调用根对话框.这要干净得多.

Controller: I cleaned it up. It should really only be calling the root dialog. This is much cleaner.

RootDialog :将首先调用该表单.如果表单成功，它将继续进入"QnA"对话框.

RootDialog: Will first call the form. If the form was successful it will continue to the QnA dialog.

ProfileForm :仅删除FormCompleted布尔值.没必要.

ProfileForm: only deleted the FormCompleted boolean. Was not necessary.

QnADialog :将使用填写的名称启动对话框并提出问题.我保留了默认代码以获取一些反馈.

QnADialog: Will start the dialog and ask a question, using the name filled in. I kept the default code to get some feedback.
