Added capability to change language in Dialogflow #10

Closed lomluca-zz closed 6 years ago

lomluca-zz commented 6 years ago

I added few lines to support multi-language in Dialogflow. I suppose that in the message object the field "language" could be present: if not undefined, the language field of the apiai instance is updated accordingly: app.language = message.language

In this way Dialogflow will answer in the same language of the user, if trained.

Take a look at the dev branch; I merged your changes, and made a few additions:

app.language must be set explicitly to en when no language is specified, otherwise a call made by specifying a language will change the default for future calls.
added debug logging to specify the language for the call
added docs
added tests

Please test and comment if possible.

Good additions. I've read everything, it seems ok. I tried to use dev branch module in my node app and it runs perfectly. Thanks!
