我希望我的Google Assistant应用程序先与我的网络服务器对话，然后再与dialogflow对话

Question

I want my Google Assistant application to talk to my webserver first and then Dialogflow. The way DialogFlow is documented, the Assistant talks to it first, and then it is passed to my webhook. I want to do it the other way.

Answer 1

To have the Google Assistant talk directly to your server (without Dialogflow in between) you need to use the Actions SDK . You'll create an actions.json file which defines triggering information and the URL for a webhook. (You can't get rid of the webhook - just change how it is called.) Your webhook will be called with JSON that has a different format from Dialogflow's JSON format, or you can use the node.js library which has a similar interface to the Dialogflow version.

Your webhook can, then, call Dialogflow using the /query endpoint (for Dialogflow V1 API) or the detectIntent message (for the Dialogflow V2 API). You can send it the text from the user or an event indicating the user's action (or, really, anything you want) along with parameters and Contexts that you wish. Dialogflow will send a reply, either from it's reply section or by sending it to another fulfilment webhook - whatever you choose.

Your server will get this reply, along with any Contexts and parameters that are set. It sounds like you'll send the reply to the user, probably without further processing, although you can do whatever you want. You may want to store the context information in the conversation token , the user storage object , or in some other data store your server wishes to use.

There are some samples for using the Actions SDK although none of them illustrate calling Dialogflow from the webhook. (It is not a very common pattern - most use cases work better the other way.) The samples for Dialogflow are mostly for webhooks, although the "Agent to human handoff" does illustrate sending to Dialogflow from your code.
