Question

我正在使用LUIS模板创建聊天机器人，并且我有一个名为StartTest的意图，其含义如下：

Begin [TestNameEntity] on [GearEntity] and [RPMEntity]
Begin [TestNameEntity] on [GearEntity]
Begin [TestNameEntity]

如果用户输入的内容与第一句话相符，则我拥有所需的所有实体。但是，如果它的输入与第二个发音匹配，我必须问他RPM。第三点，我必须询问齿轮和RPM。

但是对于第二和第三种话语，我需要知道用户对[TestNameEntity]所说的话，像这样：

User: Begin test 1 on second gear
Bot: What RPM?
User: 2500

我该如何实现？

Answer 1

一旦调用了Intent方法，就可以使用此逻辑

result.Entities[0].Type to get entity name

因此您可以迭代result.Entities来获取用户输入的所有实体。如果缺少三个实体中的任何一个，您可以要求提示。这是如何实现的示例代码。

//global variables
public string CurrentGear { get; set; }
public string CurrentRpm { get; set; }



[LuisIntent("StartTest")]
public async Task StartTestIntent(IDialogContext context, LuisResult result)
{
     if (result.Entities != null && result.Entities.Count >0)
    {
        //sample you will get selected entity type 
         //var ent1=result.Entities[0].Type;

        var userValues=GetUserEntities(result);
        if(userValues["GearEntity"]==null)
            showGearPrompt(context);
        if(userValues["RPMEntity"]==null)
            showRpmPrompt(context);
    }
}

private string[] GetUserEntities(LuisResult result)
{
    //your logic here
    //return list of entities;
}

private async Task showGearPrompt(IDialogContext context)
{
     PromptDialog.Text(  
        context: context,  
        resume: OnGearOptionReceivedAsync,  
        prompt: "please enter Gear Value",  
        retry: "Sorry, I didn't understand that. Please try again."  
    );  

}

 public virtual async Task OnGearOptionReceivedAsync(IDialogContext context, IAwaitable<string> gear)
{
    string response = await gear;  
    CurrentGear = response; 
}

private async Task showRpmPrompt(IDialogContext context)
{
    PromptDialog.Text(  
        context: context,  
        resume: OnRpmOptionReceivedAsync,  
        prompt: "please enter RPM Value",  
        retry: "Sorry, I didn't understand that. Please try again."  
    );  
}

 public virtual async Task OnRpmOptionReceivedAsync(IDialogContext context, IAwaitable<string> rpm)
{
    string response = await rpm;  
    CurrentRpm  = response; 
}
