5.3.通过drf的apiview实现api

drf的优势

• The Web browsable API is a huge usability win for your developers.

• Authentication policies including packages for OAuth1a and OAuth2.

• Serialization that supports both ORM and non-ORM data sources.

• Customizable all the way down - just use regular function-based views if you don't need the more powerful features.

• Extensive documentation, and great community support.

• Used and trusted by internationally recognised companies including Mozilla, Red Hat, Heroku, and Eventbrite.
