Handle overwrite output response #34

Closed deiong closed 7 years ago

deiong commented 7 years ago

hi, i am trying to figure out how to overwrite the output in middleware.after = function(message, conversationResponse, callback)

i tried to modify the last line to

conversationResponse.output.text = 'This is my custom output line';

however I'm guessing its read only as this causes it to crash. in previous lines i use conversationResponse.output.text to obtain what the bot will say so i know its valid. it just won't let me overwrite it.

we plan on using a database to get custom responses. however I'm stuck trying to figure out how to overwrite the default output.

any help is appreciated.

thanks Dion

Hi,

The output must adhere to the format of Conversation Service's output, which is a list of Strings. Also, unless you change the middleware.interpret's callback function, you don't have to change the output yourself. You just have to call the callback function given as a parameter in the after function with the Conversation response object (callback(null,response)).

Let me know if you have more questions, Steven
