1、drf初步使用

  • 安装：pip install djangorestframework

  • 注册：在settings.py中

    • INSTALLED_APPS = [
    "django.contrib.staticfiles",
    "app01.apps.App01Config",
    "rest_framework"
]

      ## 1、路由显示

      #### 1-方法一：函数方式

      ```python
      # urls.py
      from django.urls import path
      from app01 import views

      urlpatterns = [
          # path("admin/", admin.site.urls),
          path("auth/", views.auth),
          path("login/", views.login),
      ]

from rest_framework.decorators import api_view
from rest_framework.response import Response

@api_view(['GET'])	# 需要使用装饰器
def login(request):
    return Response({"status": True, "message": "Hello World!"})

2-方法二：类方式 (后续主要使用)

# urls.py
urlpatterns = [
    path("info/", views.InfoView.as_view()),
]

from rest_framework.response import Response
from rest_framework.views import APIView

class InfoView(APIView):
    def get(self, request):
        return Response({"status": True, "message": "Hello view"})

2、FBV（函数视图）和CBV（类视图）

    path("info/", views.InfoView.as_view()),	# CBV
]

# views.py
from django.http import JsonResponse
from django.views import View

class InfoView(View):
    
    def get(self, request,*args, **kwargs):
        pass
    def post(self, request,*args, **kwargs):
        pass
    def put(self, request,*args, **kwargs):
        pass
    def delete(self, request,*args, **kwargs):
        pass

在使用drf时，会遇见ContenType错误，解决方法：

# 在settings.py加入下面语句
REST_FRAMEWORK={
    "UNAUTHENTICATED_USER": None,
}
