python试用rest_framework写接口文件

rest_framework官方网站：http://www.django-rest-framework.org
1、安装
        

pip install djangorestframework

2、在settings.py里添加配置
    INSTALLED_APPS += ['rest_framework']

    INSTALLED_APPS += ['rest_framework.authtoken'] //authtoken验证身份是否合法
    INSTALLED_APPS += ['corsheaders']  //解决接口跨域问题
MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',

]

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.AllowAny',
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.TokenAuthentication',
    )
}

#跨域增加忽略
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_ALLOW_ALL = True
CORS_ORIGIN_WHITELIST = (
    '*'
)

CORS_ALLOW_METHODS = (
    'GET',
    'OPTIONS'
    'POST',
)

CORS_ALLOW_HEADERS = (
     '*'

)

3、在views.py例子
from rest_framework.decorators import api_view, authentication_classes, permission_classes
from rest_framework.response import Response
from rest_framework.authentication import SessionAuthentication, TokenAuthentication

from rest_framework.permissions import IsAuthenticated
@api_view(['GET'])
@authentication_classes((TokenAuthentication,SessionAuthentication))
@permission_classes((IsAuthenticated,))
def index(request):
    result = [request.GET.get('name')]

    return Response(result)
