我想为某个时隙创建一个dialogHook,最好说是一个验证类型的东西。如果时隙返回true,那么只有我会启动我的elicit时隙,否则它会照常运行。请帮助我的方法。我对lex比较陌生。
我曾试着在智囊团中进行对话,但这不起作用。
def lambda_handler(event,context):
os.environ['TZ']='America/New_York'
time.tzset();
logger.debug('event.bot.name={}'.format(event['bot']['name']))
return dispatch(event);
def dispatch(intent_request):
intent_name=intent_request['currentIntent']['name']
if intent_name=='HotelReservation':
return book_hotel(intent_request)
def book_hotel(intent_request):
slots=intent_request['currentIntent']['slots']
welcome=intent_request['currentIntent']['slots']['welcome']
location=intent_request['currentIntent']['slots']['Location']
fromDate=intent_request['currentIntent']['slots']['FromDate']
adultCount=intent_request['currentIntent']['slots']['adultCount']
nights=intent_request['currentIntent']['slots']['nights']
childExists=intent_request['currentIntent']['slots']['childExists']
source=intent_request['invocationSource']
session_attributes={}
if source=='DialogCodeHook'and childExists.lower()=='yes':
session_attributes={}
return elicit_slot (
session_attributes,
'HotelReservation',
'childCount',
'AMAZON.NUMBER',
{
'contentType':'PlainText',
'content':'Please enter number of Children'
}
)
elif source=='DialogCodeHook':
output_session_attributes = intent_request['sessionAttributes'] if intent_request['sessionAttributes'] is not None else {}
return delegate(output_session_attributes, intent_request['currentIntent']['slots'])
else:
return close (
session_attributes,
'Fulfilled',{
'contentType':'PlainText',
'content':'Here is the temparature in'
}
)
#for fullfillment function
def close(session_attributes,fulfillment_state,message):
response={
'sessionAttributes':session_attributes,
'dialogAction':{
'type':'Close',
'fulfillmentState':fulfillment_state,
'message':message
}
}
return response
#for elicit slot return
def elicit_slot(session_attributes, intent_name,slots,slot_to_elicit,message):
response= {
'sessionAttributes': session_attributes,
'dialogAction': {
'type': 'ElicitSlot',
'intentName': intent_name,
'slots': slots,
'slotToElicit': slot_to_elicit,
'message': message
}
}
return response;
def delegate(session_attributes, slots):
return {
'sessionAttributes': session_attributes,
'dialogAction': {
'type': 'Delegate',
'slots': slots
}
}
事实上,我的插槽应该像往常一样运行,但在智囊师插槽之后,我想发送一个引出的响应。
This is the image of the slots available
最佳答案
根据我的理解,您正在询问用户Do you have any children
并将响应存储在childExists
槽中,如果答案是yes,则您希望询问孩子的数量。
所以根据我的说法,你需要有一个额外的槽来存储孩子的数量。由于此插槽并不总是必需的,所以不要在amazon lex控制台中将其标记为必需。
现在,您将在childCount
中检查此项,并且仅当DialogCodeHook
中没有值时才相应地询问用户我们使用这些条件的组合是为了确保它不会无限期地运行。
def book_hotel(intent_request):
slots = intent_request['currentIntent']['slots']
welcome = slots['welcome']
location = slots['Location']
fromDate = slots['FromDate']
adultCount = slots['adultCount']
nights = slots['nights']
childExists = slots['childExists']
childCount = slots['childCount']
source = intent_request['invocationSource']
if source == 'DialogCodeHook':
output_session_attributes = intent_request['sessionAttributes'] if intent_request['sessionAttributes'] is not None else {}
if childExists.lower() == 'yes':
if not childCount:
return elicit_slot (
output_session_attributes,
'HotelReservation',
slots,
'childCount',
{
'contentType':'PlainText',
'content':'Please enter number of Children'
}
)
return delegate(output_session_attributes, intent_request['currentIntent']['slots'])
if source == 'FulfillmentCodeHook':
return close (
output_session_attributes,
'Fulfilled',{
'contentType':'PlainText',
'content':'Here is the temparature in'
}
)
希望有帮助。
