更改Microsoft Bot Framework中的消息stream

你好我是微软Bot Framework的新手，我有一个问题，我找不到答案。 我有一个FormFlow询问用户的一些问题，在一个特定的问题后，我想让机器人做一些逻辑，并相应地显示消息（例如，如果用户select选项1，然后显示消息X，如果用户select选项2显示消息Y）。

这是我的代码：

using Microsoft.Bot.Builder.FormFlow; using Microsoft.Bot.Builder.Dialogs; using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace Bot_CRM.FormFlow { public enum RequestOptions { Unknown, CheckStatus, CreateCase }; [Serializable] public class CaseFormFlow { public RequestOptions RequestType; [Prompt("What is your first name?")] public string FirstName; public string LastName; public string ContactNumber; [Prompt("Please enter your id")] public string Id; public static IForm<CaseFormFlow> BuildForm() { OnCompletionAsyncDelegate<CaseFormFlow> processRequest = async (context, state) => { await context.PostAsync($@"Thanks for your request"); }; return new FormBuilder<CaseFormFlow>() .Message("Hello and welcom to my service desk bot") .Field(nameof(FirstName)) .Message("hello {FirstName}") .Field(nameof(Id)) .Field(nameof(RequestType)) => //here if user select 1 start flow of check status and if user select 2 start flow of create case .AddRemainingFields() .Message("Thank you request. Our help desk team will get back to you shortly.") .OnCompletion(processRequest) .Build(); } } } 

Ezequielbuild议后更新的代码：

  return new FormBuilder<CaseFormFlow>() .Message("Hello and welcom to my service desk bot") .Field(nameof(FirstName)) .Message("hello {FirstName}") .Field(new FieldReflector<CaseFormFlow>(nameof(RequestType)) .SetActive(state => state.AskUserForRequestType) .SetNext((value, state) => { var selection = (RequestOptions)value; if (selection == RequestOptions.CheckStatus) { return new NextStep(new[] { nameof(Id) }); } else { return new NextStep(); } })) 

先谢谢您的帮助

这是一个很好的问题。关键是使用Field<T>类的SetActive和SetNext方法。 你应该考虑使用FieldReflector类; 尽pipe你可以实现你自己的IField。

在FormFlow文档的dynamic字段部分描述了SetActive。 基本上它提供了一个代表，使基于条件的字段。

SetNext将允许您根据您的自定义逻辑决定下一步表单的哪一步。

您可以看看ContosoFlowers示例。 在订单表格中; 类似的事情正在完成。

  public static IForm<Order> BuildOrderForm() { return new FormBuilder<Order>() .Field(nameof(RecipientFirstName)) .Field(nameof(RecipientLastName)) .Field(nameof(RecipientPhoneNumber)) .Field(nameof(Note)) .Field(new FieldReflector<Order>(nameof(UseSavedSenderInfo)) .SetActive(state => state.AskToUseSavedSenderInfo) .SetNext((value, state) => { var selection = (UseSaveInfoResponse)value; if (selection == UseSaveInfoResponse.Edit) { state.SenderEmail = null; state.SenderPhoneNumber = null; return new NextStep(new[] { nameof(SenderEmail) }); } else { return new NextStep(); } })) .Field(new FieldReflector<Order>(nameof(SenderEmail)) .SetActive(state => !state.UseSavedSenderInfo.HasValue || state.UseSavedSenderInfo.Value == UseSaveInfoResponse.Edit) .SetNext( (value, state) => (state.UseSavedSenderInfo == UseSaveInfoResponse.Edit) ? new NextStep(new[] { nameof(SenderPhoneNumber) }) : new NextStep())) .Field(nameof(SenderPhoneNumber), state => !state.UseSavedSenderInfo.HasValue || state.UseSavedSenderInfo.Value == UseSaveInfoResponse.Edit) .Field(nameof(SaveSenderInfo), state => !state.UseSavedSenderInfo.HasValue || state.UseSavedSenderInfo.Value == UseSaveInfoResponse.Edit) .Build(); } } }
