问题
I am developing an api.ai bot that will search for the Vendor name in the database.
a ) if vendor exist -> provide username -> provide password
b) if vendor doesn't exist -> (add vendor -> yes ) or (add vendor -> No)
I have a webhook which is checking the vendor exist in database or not .
Bot Scenario: (Example )
Case1:
User: Do Alpha exist as a vendor?
Bot: yes, Alpha exist in Database. Please Provide User Name.
User: abc@gmail.com
Bot: Please Provide Password?
User: abcdef
Bot : Welcome
Case 2:
User: Do Beta exist as a vendor ?
Bot: No Beta is not a vendor. Do you want to Register?
Case 1:
User: Yes
Bot: Please fill this Form.
Case 2:
User: No
Bot: Is there any other way I can help
One thing I have figured out, I have to use output context to trigger the intent. But how can I do it in this complex case? and how can I call multiple to follow up intent using Output Context?
I might be using a bad approach, Is there any other way to solve this ?
I do have a follow-up question.
- when we pass the fulfillment response back to dialogue flow. The response print on bot console will be the default text response, how can I get "fulfillmentText" to be the Response.
Thank you Guys. This is the followup Intent scenario.
回答1:
This is not complex, you are doing it wrong by having two intents for collecting username/password.
Try the following way
When you detect that your vendor is present - set the context in webhook, as say, "vendor-present"
When the vendor is not present - set the context in webhook, as say, "vendor-new"
Use lifespan (the number at the left side of the context) to set the lifetime or validity of the context.
Create a separate intent for existing vendor - say "Vendor Data Collection" for collecting username and password. Set input context as "vendor-present" in the Dialogflow. Here you will collect these as parameters in the same intent (see image below). Mark these parameters as 'required' so that they must be collected by your bot. Use the Prompt section to put your response question for collecting information like "Please provide username".
If the vendor is not present, use existing intents and set input context as "vendor-new" in the Dialogflow.
Now, few things to note - the username parameter can be collected using the system entity @sys.given-name. But it is not very accurate with the Non-American/English names. I am not sure if this is improved or not. Secondly, there is no system entity to collect passwords, so you need to set the entity as @sys.any and in the webhook, you need to use regex to extract passwords on your own. BTW - you are not supposed to share passwords!
Hope this helped you!
