Basics
It mainly uses djangorestframework module and provides api. Drf Chinese document http://drf.jiuyou.info/#/drf/requests
The basic environment configuration can be seen in the first article above.
The basic configuration information of mvvc backend is similar to that of mvc backend. The following is a list of different parts.
