此问题通常是由于在管理AWS Lex V2预定义的Intents和Slots时,没有正确配置DialogCodeHook和FulfillmentCodeHook所致。为了解决此问题,您可以尝试以下步骤:
1.在AWS控制台中,找到您的Bot并打开“Build”页面。
2.在Intents和Slots列表中找到名为“DialogCodeHook”和“FulfillmentCodeHook”的Intent,并确保这两个Intents都包含在您的Bot中。
3.在每个Intent中,找到名为“Code Hook”的选项,并确保您已正确配置了DialogCodeHook和FulfillmentCodeHook。
4.确保您在DialogCodeHook Intent中正确处理所有必需的Slot值,并将该Intent中的Invocation Source设置为“DialogCodeHook”。
5.在FulfillmentCodeHook Intent中,确保您已正确处理所有必需的信息和操作,并将该Intent中的Invocation Source设置为“FulfillmentCodeHook”。
以下是一个示例代码片段,这将按顺序设置所有的slots,并将Invocation Source从DialogCodeHook更改为FulfillmentCodeHook:
def lambda_handler(event, context):
intent_name = event['request']['intent']['name']
if intent_name == 'MyIntent':
slots = event['request']['intent']['slots']
# Set all required slots
for slot in slots:
if slots[slot].get('value'):
setattr(myObj, slot, slots[slot]['value'])
# Check all the required slots are filled
all_slots_filled_all_values = True
for slot_name, slot_details in dialog_state['slot_details'].items():
if slot_details['type'] != 'Amazon.IntentSlotType':
if slot_details.get('value') is None:
all_slots_filled_all_values = False
# If all slots are filled, performing fulfillment
if all_slots_filled_all_values:
response = {
"sessionState": {
"dialogAction": {
"type": "Close",
"fulfillmentState": "Fulfilled",
"message": {
"contentType": "PlainText",
"content": "This is your fulfillment response."
}
},
"intent": {
"state": "Fulfilled",
"name": intent_name,
"slots": slots
}
},
"requestAttributes": {
"someKey": "someValue"
},
"sessionId": event['sessionId'],
"requestId": event['requestId']
