基于MS Bot Framework中的响应的分支对话框/表单

我们正在尝试使用MS Bot框架，但尚未完全弄清楚如何实现此方案:

We're experimenting with the MS Bot Framework and haven't quite worked out how to do this scenario:

我们有一个LUIS对话框(类型为<object>)，该对话框工作正常并且经过了适当的培训.为了使用常见的三明治示例，LUIS意图要寻找的基本知识是用户询问订单的状态.如果问题中提供了订单号("1234号订单的状态是什么?")，则LUIS对话框将进行查找并直接报告状态(当前所有状态).

We have a LUIS Dialog (type <object>), which is working correctly and is trained properly. To use the common sandwich example, the basics of what LUIS intent is looking for is the user asking for the status of an order. If the order number was provided in the question ("What is the status of order 1234?"), then the LUIS dialog does the lookup and reports the status directly (which is all currently working).

但是，如果用户只是在不提供订单号的情况下触发了意图(我想查询订单的状态.")，我想启动另一个对话框/表单来询问用户是否他们想按地址或订单号查找订单，然后根据他们的回答方式进行适当的数据库查找.

However, if the user just triggers the intent without providing the order number ("I'd like to look up the status of an order."), I'd like to launch another dialog/form to ask the user if they'd like to look up the order by address or order number, and then do the appropriate DB lookup based on how they answer.

我只是不确定如何配置表单/对话框(或者在这种情况下最好)，以便根据他们选择地址还是数字查找来进行不同的查找.

I'm just not sure how to configure the Form/Dialog (or even which is best in this case) to do a different lookup based on if they choose address or number lookup.

到目前为止，这是意图:

Here's the intent so far:

private readonly BuildFormDelegate<OrderStatusDialog> OrderStatusDelegate;

[LuisIntent(nameof(LuisIntents.OrderStatus))]
public async Task OrderStatus(IDialogContext context, LuisResult result)
{
    // Order number(s) were provided
    if (result.Entities.Any(Entity => Entity.Type == nameof(LuisEntityTypes.OrderNumber)))
    {
        // Loop in case they asked about multiple orders
        foreach (var entity in result.Entities.Where(Entity => Entity.Type == nameof(LuisEntityTypes.OrderNumber)))
        {
            var orderNum = entity.Entity;

            // Call webservice to check status
            var request = new RestRequest(Properties.Settings.Default.GetOrderByNum, Method.GET);
            request.AddUrlSegment("num", orderNum);
            var response = await RestHelper.SendRestRequestAsync(request);

            var parsedResponse = JObject.Parse(response);

            if ((bool)parsedResponse["errored"])
            {
                await context.PostAsync((string)parsedResponse["errMsg"]);
                continue;
            }

            // Grab status from returned JSON
            var status = parsedResponse["orderStatus"].ToString();

            await context.PostAsync($"The status of order {orderNum} is {status}");
        }

        context.Wait(MessageReceived);
    }
    // Order number was not provided
    else
    {
        var orderStatusForm = new FormDialog<OrderStatusDialog>(new OrderStatusDialog(), OrderStatusDelegate,
            FormOptions.PromptInStart);
        context.Call<OrderStatusDialog>(orderStatusForm, CallBack);
    }
}

private async Task CallBack(IDialogContext context, IAwaitable<object> result)
{
    context.Wait(MessageReceived);
}

和表格:

public enum OrderStatusLookupOptions
{
    Address,
    OrderNumber
}

[Serializable]
public class OrderStatusDialog
{
    public OrderStatusLookupOptions? LookupOption;

    public static IForm<OrderStatusDialog> BuildForm()
    {
        return new FormBuilder<OrderStatusDialog>()
            .Message("In order to look up the status of a order, we will first need either the order number or your delivery address.")
            .Build();
    }
}
