推荐答案

我强烈建议您查看以下资源，以便在Django中创建REST API:

I would highly encourage you to look at these resources for creating a REST API in Django:

Django Rest Framework: http://www.django-rest-framework.org/

Django Rest Framework: http://www.django-rest-framework.org/

Tastypie API: http://tastypieapi.org/

我个人已经成功地使用了Deliciouspie来创建一个REST API，以从模型返回JSON数据.这是开始使用的Tastypie文档的链接: https://django-tastypie.readthedocs. org/en/latest/

I have personally used Tastypie successfully to create a REST API returning JSON data from models. Here is a link to the Tastypie documentation to get started: https://django-tastypie.readthedocs.org/en/latest/
