c# - 从Form Flow获取数据并将其输入到api调用中

我一直坚持从使用Form Flow创建的表单获取变量值。我需要用户提供这四个过滤器，以便可以将它们插入我的API调用中并返回JSON对象。

在此代码中，仅在澄清时在URL中手动指定了过滤器。

当我运行此代码时，首先执行API调用，然后该表单出现在Bot-framework模拟器上。

[LuisIntent("ProductSearch")]
public async Task ProductSearch(IDialogContext context, LuisResult result)
{
    if (result.TryFindEntity("SearchKeyword", out EntityRecommendation SearchKeywordEntity))
    {
        await context.PostAsync($"Searching for '{SearchKeywordEntity.Entity}'...");

        Enquiry enqform = new Enquiry();
        FormDialog<Enquiry> Enquiryform = new FormDialog<Enquiry>(enqform, Enquiry.BuildEnquiryForm, FormOptions.PromptInStart);
        context.Call(Enquiryform, EnquiryFormSubmitted);

        ApiCall api = new ApiCall();
        string json = ApiCall.GET($"http://127.0.0.1:5000/search?search_keyword=water&av_filter=Asia&in_filter=Chemicals&aa_filter=Home Care&pg_filter=Polymers");
        await context.PostAsync(json);
    }
}

这是Enquiry.cs

using Microsoft.Bot.Builder.FormFlow;
using System;

namespace BASF_Bot_Application2.Dialogs
{
    [Serializable]
    public class Enquiry
    {
        [Prompt("Would you like to apply some filters to get more specific results? {||}")]
        public bool ApplyFilters { get; set; }

        [Prompt("Where do yo want the product? {||}")]
        public Availability AvailabilityRequired { get; set; }
        public enum Availability
        {
            Global, Africa, Asia, Australia, Europe, North_America, South_America
        }

        [Prompt("What industry would you prefer? {||}")]
        public Industries IndustriesRequired { get; set; }
        public enum Industries
        {
            Agriculture, Automotive & Transportation, Chemicals, Construction, Electronics & Electrics, Energy & Resources, Furniture & Wood, Home Care and I&I Cleaning, Nutrition, Packaging & Print, Paint & Coatings Industry, Personal Care & Hygiene, Plastics & Rubber, Pulp & Paper, Textile, Leather & Footwear
        }

        [Prompt("Where is the Area of Application? {||}")]
        public Areas_of_Application Areas_of_ApplicationRequired { get; set; }
        public enum Areas_of_Application
        {
            Ag Chem Additives, Cleaning and caring, Construction, Electronics, Food and Beverage, Formulation Technologies, Health, Home and Garden, Home Care, Industrial and Institutional Cleaning, Information technology, Manufacturing, Measuring and control technol., Packaging, Paper and Printing
        }

        public static IForm<Enquiry> BuildEnquiryForm()
        {
            return new FormBuilder<Enquiry>()
                .Field("ApplyFilters")
                .Field("AvailabilityRequired")
                .Field("Industries")
                .Field("Areas_of_Application")
                .Build();
        }
    }
}

最佳答案

用户填写/填写表单后，将触发EnquiryFormSubmitted，因此您将在其中获取用户输入的值，并在此进行API调用。

private async Task EnquiryFormSubmitted(IDialogContext context, IAwaitable<Enquiry> result)
    {
        var enquiry = await result;
        //All the user entered details are available in the enquiry object.
        ApiCall api = new ApiCall();
        string parameters = $"search_keyword=water&av_filter={enquiry.Availability}&in_filter={enquiry.Industries}&aa_filter={enquiry.Areas_of_Application}&pg_filter=Polymers";
        string json = ApiCall.GET($"http://127.0.0.1:5000/search?" + parameters);
        await context.PostAsync(json);
        //Whatever more logic is required
    }
