Django REST framework 是一个强大且灵活的工具包，用以构建Web APIs。
- 在线可视的API，对于赢得你的开发者们十分有用
- 验证策略涵盖了OAuth1a和OAuth2
- 同时支持ORM和非ORM数据源的序列化
- 可以配置各个环节，若无需更多强大的特性，使用一般基于类（function-based）的视图（views）即可
- 大量的文档，强力的社区支持
- 大公司如同Mozilla和Eventbrite，也是忠实的使用者
REST framework 有以下的要求：
下面是可选的包：
pip install djangorestframework pip install markdown # 可选依赖包 pip install django-filter # 可选依赖包
INSTALLED_APPS = (
...
‘rest_framework‘,
)
REST_FRAMEWORK = {
# 编码格式
‘UNICODE_JSON‘: False,
}
