我正在努力建立一个alexa技能,其中要求是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}
最终方法应从先前的广告位(主题和日期)中获取值并创建约会。 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。
*实施例
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?如果可以的话我该怎么做?
谢谢和问候

我相信您应该可以使用此处提到的session.setAttribute()
和session.getAttribute()

session.setAttribute
,但是,如果由于某种原因你想要保留session.setAttribute
可能无法接受的内容,你总是可以拥有字段变量始终可用,直到会话结束为止,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;
}
我所做的就是在更高的范围内(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。

我使用会话来实现我的查询......
Map<String, Slot> slots = intent.getSlots();
Slot example = slots.get(SampleSlot);
session.setAttributes(Sample_String);
session.getAttributes(SampleSessionString);
