Django中的csrf认证实现的原理
调用 process_view 方法
检查视图是否被 @csrf_exempt （免除csrf认证）
- 去请求体或cookie中获取token
情况一（全站使用csrf认证，局部不想使用csrf认证）
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware', # 全站使用csrf认证
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
如果我想让某个请求不通过csrf认证可以这样做
from django.views.decorators.csrf import csrf_exempt @csrf_exempt # 该函数无需认证 def users(request): user_list = ['alex','oldboy'] return HttpResponse(json.dumps((user_list)))
情况二（全站不使用csrf认证，局部想使用csrf认证）
MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', #'django.middleware.csrf.CsrfViewMiddleware', # 全站不使用csrf认证 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ]
如果我想让某个请求使用csrf认证可以这样做
from django.views.decorators.csrf import csrf_exempt,csrf_protect @csrf_protect # 该函数需认证 def users(request): user_list = ['alex','oldboy'] return HttpResponse(json.dumps((user_list)))
CBV小知识,csrf时需要使用
- @method_decorator(csrf_exempt)
- 在dispatch方法中（单独方法无效）
方式一
from django.views.decorators.csrf import csrf_exempt,csrf_protect
from django.utils.decorators import method_decorator
class StudentsView(View):
@method_decorator(csrf_exempt)
def dispatch(self, request, *args, **kwargs):
return super(StudentsView,self).dispatch(request, *args, **kwargs)
def get(self,request,*args,**kwargs):
print('get方法')
return HttpResponse('GET')
def post(self, request, *args, **kwargs):
return HttpResponse('POST')
def put(self, request, *args, **kwargs):
return HttpResponse('PUT')
def delete(self, request, *args, **kwargs):
return HttpResponse('DELETE')
方式二
from django.views.decorators.csrf import csrf_exempt,csrf_protect
from django.utils.decorators import method_decorator
@method_decorator(csrf_exempt,name='dispatch')
class StudentsView(View):
def get(self,request,*args,**kwargs):
print('get方法')
return HttpResponse('GET')
def post(self, request, *args, **kwargs):
return HttpResponse('POST')
def put(self, request, *args, **kwargs):
return HttpResponse('PUT')
def delete(self, request, *args, **kwargs):
return HttpResponse('DELETE')
