They are used for processing API requests from users. If you want to add some new actions in the 0Mind API, you should implement a new request handler. 0Mind based on tornado web server functionality and implements it's handler system. All of the request handlers in 0Mind are stored in request_handlers directory grouped by their speciality.
Your custom request handler should be inherited from one of these classes:
- components/base_handler.BaseHandler
- components/model_handler.ModelHandler
- tornado.web.RequestHandler (if it's so specific)
After implementation of the request handler you should attach it to your server's application. For 0Mind see file model_pool.py:_init_service() method.
Attention! For best back compatibility don't change existing request handlers's HTTP/JSON interface. For example: you can add optionaly params but don't change the names and amount of obligatory. Just the same can be said about HTTP headers.
