---

安装框架

#sudo pip3 install django
#sudo pip3 install markdown
#sudo pip3 install djangorestframework 

启动项目

#django-admin.py startproject MyRestSite
#cd MyRestSite
#python manage.py makemigrations
#python manage.py migrate
#python manage.py createsuperuser

配置文件settings.py

# Application definition

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
)

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'
    ]
}

编写模型

models.py

class TableName(models.Model):
    xxx = xxxx(xxx=xxx)
    class Meta:
        xxxxxxx

模型序列化

serializers.py

from rest_framework import serializers
class TableNameSerializer(serializers.ModelSerializer):
    class Meta:
        model = TableName
        fields = ('xxxx', 'xxxxx', 'xxxx', 'xxxxx')

视图路由

views.py

from rest_framework.renderers import JSONRenderer
from rest_framework import serializers
class JSONResponse(HttpResponse):
    """
    用于返回JSON数据.
    """

    def __init__(self, data, **kwargs):
        content = JSONRenderer().render(data)
        kwargs['content_type'] = 'application/json'
        content='{"xxxxx":'+content+'}'
        super(JSONResponse, self).__init__(content, **kwargs)

@csrf_exempt
def xxxxxxxxx(request,xxxxxxxxxx):

    if request.method == 'GET':
       ...
        return JSONResponse(serializer.data)

路由转发

urlpatterns = [
    ...
    url(r'^api/x/xxxxx/xxxxx$', xxxxxxxs),
]

测试运行

#python3 ./manage.py runserver
# curl -H 'Accept: application/json; indent=4' -u username:password http://127.0.0.1:8000/apiurls/
