我有一个机器人,它将在数据库中寻找人。如果该人的名字未知,我想让Bot再次询问:“名字不明,请再次输入名字”
这是我现在完成的步骤:
public class MessagesController : ApiController
{
/// <summary>
/// POST: api/Messages
/// Receive a message from a user and reply to it
/// </summary>
public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
{
await Conversation.SendAsync(activity, () => new RootDialog());
}
.... (more code here)
在RootDialog中:
public async Task StartAsync(IDialogContext context)
{
context.Wait(this.MessageReceivedAsync);
}
public virtual async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
{
var message = await result;
if (message.Text.ToLower().Contains("help")
|| message.Text.ToLower().Contains("support")
|| message.Text.ToLower().Contains("problem"))
{
await context.Forward(new SupportDialog(), this.ResumeAfterSupportDialog, message, CancellationToken.None);
}
else
{
context.Call(new SearchDialog(), this.ResumeAfterOptionDialog);
}
}
并在SearchDialog中:
public async Task StartAsync(IDialogContext context)
{
await context.PostAsync($"Hi {context.Activity.From.Name}, Looking for someone?.");
var SearchFormDialog = FormDialog.FromForm(this.BuildSearchForm, FormOptions.PromptInStart);
context.Call(SearchFormDialog, this.ResumeAfterSearchFormDialog);
}
private IForm<SearchQuery> BuildSearchForm()
{
OnCompletionAsyncDelegate<SearchQuery> processSearch = async (context, persoon) =>
{
await context.PostAsync($"There we go...");
};
return new FormBuilder<SearchQuery>()
.Field(nameof(SearchQuery.Name))
.Message($"Just a second...")
.AddRemainingFields()
.OnCompletion(processSearch)
.Build();
}
private async Task ResumeAfterSearchFormDialog(IDialogContext context, IAwaitable<SearchQuery> result)
{
try
{
var searchQuery = await result;
var found = await new BotDatabaseEntities().GetAllWithText(searchQuery.Name);
var resultMessage = context.MakeMessage();
var listOfPersons = foundPersons as IList<Person> ?? foundPersons.ToList();
if (!listOfPersons.Any())
{
await context.PostASync($"No one found");
}
else if (listOfPersons.Count > 1)
{
resultMessage.AttachmentLayout = AttachmentLayoutTypes.List;
resultMessage.Attachments = new List<Attachment>();
this.ShowNames(context, listOfPersons.Select(foundPerson => foundPerson.FullName.ToString()).ToArray());
}
else
{
await OnePersonFound(context, listOfPersons.First(), resultMessage);
}
}
catch (FormCanceledException ex)
{
string reply;
reply = ex.InnerException == null ? "You have canceled the operation";
await context.PostAsync(reply);
}
}
这是SearchQuery:
[Serializable]
public class SearchQuery
{
[Prompt("Please give the {&} of the person your looking for.")]
public string Name { get; set; }
}
现在。当我提供一个不存在的名称时,我不想重新开始对话,而只是想让Bot在此之后再次询问该问题。
if (!listOfPersons.Any())
{
await context.PostASync($"No one found");
}
真的不知道如何解决该问题。
最佳答案
嗯,我现在这样修复它:
if (!listOfPersons.Any())
{
await context.PostAsync($"Sorry, no one was found with this text");
var SearchFormDialog = FormDialog.FromForm(this.BuildSearchForm, FormOptions.PromptInStart);
context.Call(SearchFormDialog, this.ResumeAfterSearchFormDialog);
}
关于c# - Microsoft Bot Framework:在不重新启动对话框的情况下再次询问,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/41957149/
