如何通过单击bot框架c＃中的按钮来调用formflow

Question

我是编程facebook机器人的新手。我在c＃中使用了microsoft bot框架。

当用户从快速回复中选择一个选项时，我想启动对话框或表单流。

当我尝试使用此代码时，我没有得到任何响应...或我得到错误

在我的Rootdialog.cs中使用此代码：

 private async Task OnOptionSelected(IDialogContext context, IAwaitable<IMessageActivity> result)
    {
        var message = await result;

        //if you choose start parking
        if (message.Text == Resources.RootDialog_Welcome_Start)
        {
            this.order = new Models.Order();

            var promptOptions = new PromptOptions<string>(
                "Please select the city where you want to park:",
                options: new[] { "a", "b", "c" },
                promptStyler: new ());

            PromptDialog.Choice(context, this.ResumeAfterSelection, promptOptions);

        }




private async Task ResumeAfterSelection(IDialogContext context, IAwaitable<string> result)
    {
        try
        {
            var cityRange = await result;
            if (cityRange == "Brussels")
            {




context.Call(FormDialog.FromForm<Enquiry>(Enquiry.BuildEnquiryForm, FormOptions.PromptInStart), async (ctx, formResult) => ctx.Wait(this.MessageReceivedAsync));
                //var myform = new FormDialog<Enquiry>(new Enquiry(), Enquiry.BuildEnquiryForm, FormOptions.PromptInStart, null);

Enquiry.cs是

[Serializable]
public class Enquiry : LuisDialog<StartParking>
{
    private Func<IForm<Enquiry>> buildEnquiryForm;



    public Enquiry(Func<IForm<Enquiry>> buildEnquiryForm)
    {
        this.buildEnquiryForm = buildEnquiryForm;
    }

    public Enquiry()
    {
    }

    [Prompt("What time")]
    public DateTime Time { get; set; }
    [Prompt("Placenumber?")]
    public string PlaceNumber { get; set; }
    [Prompt("Platenumber?")]
    public string Platenumber { get; set; }



    public IEnumerable<EntityRecommendation> Entities { get; internal set; }



    public static IForm<Enquiry> BuildEnquiryForm()
    {
        return new FormBuilder<Enquiry>()

            .AddRemainingFields()
            .Build();
    }
}

}

Answer 1

我认为context.Call需要IDialog，因此请尝试使用Chain.From从FormDialog.FromForm构建一个：

internal static IDialog<Enquiry> MakeRoot()
{
    return Chain.From(() => FormDialog.FromForm<Enquiry>(Enquiry.BuildEnquiryForm, FormOptions.PromptInStart)); 
}

然后使用：

调用它

context.Call(MakeRoot, async (ctx, formResult) => ctx.Wait(this.MessageReceivedAsync));
