创建drf纯净项目

1)创建项目

django-admin startproject api

2）创建app

django-admin startproject api_app

3)修改settings.py注释掉一些没用的配置

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

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',
]

ROOT_URLCONF = 'api.urls'

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',
            ],
        },
    },
]

4)安装drf

pip3 install djangorestframework

5)注册drf

setttings.py

INSTALLED_APPS = [
    # 'django.contrib.admin',
    # 'django.contrib.auth',
    # 'django.contrib.contenttypes',
    # 'django.contrib.sessions',
    # 'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',        #注册drf
]

3.3创建url路由和CBV

urlpatterns = [
    # path('admin/', admin.site.urls),
    path('home/', views.home),
    path('user/', views.UserView.as_view()),     #CBV路由
]

class UserView(APIView):
    def get(self,request):
        return Response('返回成功')

这时候访问user/会报错，因为没有用户信息

Model class django.contrib.contenttypes.models.ContentType doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

需要在settings.py加入以下代码：

#将未认证用户置空
REST_FRAMEWORK = {
    "UNAUTHENTICATED_USER":None,
}
