02 DRF项目-纯净版

django restframework框架 是在django的基础上又给我们提供了很多方便的功能，让我们可以更便捷基于django开发restful API，来一个简单的实例

注意：drf支持cbv和fbv，只不过基于drf在进行api开发时，一般都是使用cbv的形式。

pip install django==3.2
pip install djangorestframework

1 核心配置

INSTALLED_APPS = [
    # 'django.contrib.admin',
    # 'django.contrib.auth',
    # 'django.contrib.contenttypes',
    # 'django.contrib.sessions',
    # 'django.contrib.messages',
    'django.contrib.staticfiles',
    'api.apps.ApiConfig',
    'rest_framework'
]

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    # 'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    # 'django.middleware.csrf.CsrfViewMiddleware',
    # 'django.contrib.auth.middleware.AuthenticationMiddleware',
    # 'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                # 'django.contrib.auth.context_processors.auth',
                # 'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

REST_FRAMEWORK = {
    "UNAUTHENTICATED_USER": None
}

2 路由

from django.contrib import admin
from django.urls import path
from api import views

urlpatterns = [
    # path('admin/', admin.site.urls),
    path('users/', views.UserView.as_view()),
]

3 视图

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


class UserView(APIView):
    def get(self, request):
        return Response("...")

报错

解决：在settings中配置

# 匿名用户配置
REST_FRAMEWORK = {
    "UNAUTHENTICATED_USER": None
}
