Django RestFulAPI 实现

    emmm，继续刚毕设呀：

    由于Client端是微信小程序，所以得提供接口：

    先修改模板：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')]
        ,
        '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',
                "django.template.context_processors.i18n",
                "django.template.context_processors.media",
            ],
        },
    },
]

 这里有个坑就是 后面那个行因为版本不一样可能也会不一样！

 引入rest_framework ：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # USE OWN PART
    'tools',
    # USE RestFUL API
    'rest_framework',
    'dj_pagination'
]

对了，最后那行是分页用的，顺便配置log：

# USE LOG :
LOGGING = {
    'version': 1,
    'disable_existing_loggers': True,
    'formatters': {
       'standard': {
            'format': '%(asctime)s [%(threadName)s:%(thread)d] [%(name)s:%(lineno)d] [%(module)s:%(funcName)s] [%(levelname)s]- %(message)s'}  # Log Format
    },
    'filters': {
    },
    'handlers': {
        'mail_admins': {
            'level': 'ERROR',
            'class': 'django.utils.log.AdminEmailHandler',
            'include_html': True,
        },
        'default': {
            'level':'DEBUG',
            'class':'logging.handlers.RotatingFileHandler',
            'filename': 'log/all.log',              # log Output file
            'maxBytes': 1024*1024*5,                # file MAX size
            'backupCount': 5,                       # The file MAX saved
            'formatter':'standard',                 # USE format ways?
        },
        'error': {
            'level':'ERROR',
            'class':'logging.handlers.RotatingFileHandler',
            'filename': 'log/error.log',
            'maxBytes':1024*1024*5,
            'backupCount': 5,
            'formatter':'standard',
        },
        'console':{
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
            'formatter': 'standard'
        },
        'request_handler': {
            'level':'DEBUG',
            'class':'logging.handlers.RotatingFileHandler',
            'filename': 'log/script.log',
            'maxBytes': 1024*1024*5,
            'backupCount': 5,
            'formatter':'standard',
        },
        'scprits_handler': {
            'level':'DEBUG',
            'class':'logging.handlers.RotatingFileHandler',
            'filename':'log/script.log',
            'maxBytes': 1024*1024*5,
            'backupCount': 5,
            'formatter':'standard',
        }
    },
    'loggers': {
        'django': {
            'handlers': ['default', 'console'],
            'level': 'DEBUG',
            'propagate': False
        },
        'django.request': {
            'handlers': ['request_handler'],
            'level': 'DEBUG',
            'propagate': False,
        },
        'scripts': {
            'handlers': ['scprits_handler'],
            'level': 'INFO',
            'propagate': False
        },
        'py_code.tools.views': {
            'handlers': ['default', 'error'],
            'level': 'DEBUG',
            'propagate': True
        }
    }
}


# Django 's Default passWord is pbkdf_sha256
# It is simple to use

#REST SETTING JUST use by ADMIN
REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': ('rest_framework.permissions.IsAdminUser',),
    'PAGE_SIZE': 10
}

#118N-China
# I don't want use the CN
# LANGUAGE_CODE = 'zh-hans'
TIME_ZONE = 'Asia/Shanghai'

 最后还加入了管理台的国际化，对了：分页配置

# QuerFix Page
# PAGINATION_DEFAULT_PAGINATION = 10      #The num of every page
# PAGINATION_DEFAULT_WINDOW = 2
# PAGINATION_DEFAULT_ORPHANS = 0
PAGINATION_INVALID_PAGE_RAISES_404 = True

     创建序列化文件：

from django.contrib.auth.models import User, Group
from rest_framework import serializers
from tools.models import product


class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ('url', 'username', 'email', 'groups')


class GroupSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Group
        fields = ('url', 'name')

# Product Serializer -->
class ProductSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = product
        fields = ('id','no','name','comment','creatTime','updateTime')

    其中 fields是返回的外露字段，而权限暂时做成这样

    在View里面写：

# RESTFUL API -ALL
# used to Mobile
# And Only in Product
#---------------------------
class ProuctsList(APIView):
    """
        USE Products List Get
    """
    def get(self,request):
        products = product.objects.all()
        serializer = ProductSerializer(products, many=True)
        return Response(serializer.data)

# User In
class UserViewSet(viewsets.ModelViewSet):
    """
    Check And Edit User's page
    """
    queryset = User.objects.all().order_by('-date_joined')
    serializer_class = UserSerializer
class GroupViewSet(viewsets.ModelViewSet):
    """
    Check and Edit Gruop's View page
    """
    queryset = Group.objects.all()
    serializer_class = GroupSerializer

配置url：

router = routers.DefaultRouter()
router.register(r'users', views.UserViewSet)
router.register(r'groups', views.GroupViewSet)

urlpatterns = [
    #RESTFUL API - System
    url(r'^', include(router.urls)),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
    #ADMIN
    url(r'^admin/', admin.site.urls),
    #QR_CODE --index
    url(r'^product/qrcode/(.+)$', views.generate_qrcode, name='qrcode'),
    url(r'^product/index.html', views.index, name='index'),
    #RESTFUL API- USER PART
    url(r'^api-taozi/wechat/products-all',views.ProuctsList.as_view()),
]

这样就得到了带权限验证登入的api。暂时到这
