获取用于先前意图（方法）的插槽值并在当前方法中使用它？

Question

我正在开发一项 alexa 技能，要求获取前一个插槽的值..

User:  Alexa,create an appointment
Alexa: please state the subject for appointment
User : subject is {subject}
Alexa: on which day?
User : {Day}
Alexa : Appointment has been created with {subject} on {day}

最终方法应该从以前的槽中获取值（主题和日期）并创建约会。到目前为止，我能够获取当前意图的插槽值...但我想获取先前意图的插槽值并在当前方法中使用它。

*例子

protected SpeechletResponse method1(Intent intent,Session session)throws 
Exception{
    SpeechletResponse response=null;

Map<String, Slot> slots =  intent.getSlots();
Slot example = slots.get(SampleSlot);
String value=example.getValue().toString();
String output="something";

response = SpeechletResponseHelper.getSpeechletResponse(output, reprompt, 
true);
    return response;
}

protected SpeechletResponse method2(Intent intent,Session session)throws 
Exception{
SpeechletResponse response=null;

****How to fetch the slot value used for method1 and use it in method2? ****

response = SpeechletResponseHelper.getSpeechletResponse(xxxx, reprompt, 
true);
return response;
}

这可能吗？如果可以，我该怎么做？

感谢和问候

Answer 1

我相信您应该能够使用此处提到的 session.setAttribute() 和 session.getAttribute() - https://github.com/amzn/alexa-skills-kit-java/blob/master/src/com/amazon/speech/speechlet/Session.java

Answer 2

如 Amit 所说，您应该可以使用 session.setAttribute，但是，如果出于某种原因您想保留某些 session.setAttribute 可能不接受的内容，您可以随时使用 字段变量 始终可用，直到会话关闭当然，一旦会话关闭，它就没有数据库了。

String output;

    protected SpeechletResponse method1(Intent intent,Session session)throws 
    Exception{
        SpeechletResponse response=null;

    Map<String, Slot> slots =  intent.getSlots();
    Slot example = slots.get(SampleSlot);
    String value=example.getValue().toString();
    output="something";

    response = SpeechletResponseHelper.getSpeechletResponse(output, reprompt, 
    true);
        return response;
    }

    protected SpeechletResponse method2(Intent intent,Session session)throws 
    Exception{
    SpeechletResponse response=null;

    ****How to fetch the slot value used for method1 and use it in method2? ****

    response = SpeechletResponseHelper.getSpeechletResponse(output, reprompt, 
    true);
    return response;
    }

我所做的只是在更高的范围内（在方法之外）初始化字符串变量 output，这使得它可用于任何其他方法。

Answer 3

我使用会话来实现这样的查询....

Map<String, Slot> slots =  intent.getSlots();
Slot example = slots.get(SampleSlot);
session.setAttributes(Sample_String);
session.getAttributes(SampleSessionString);

获取用于先前意图（方法）的插槽值并在当前方法中使用它？

Fetch the slot value used for a previous intent(method) and use it in current method?
