中间件middleware里：
import time from django.utils.deprecation import MiddlewareMixin MAX_REQUEST_PER_SECOND=2 #每秒访问次数
class RequestBlockingMiddleware(MiddlewareMixin): def process_request(self,request): now=time.time() request_queue = request.session.get('request_queue',[]) if len(request_queue) < MAX_REQUEST_PER_SECOND: request_queue.append(now) request.session['request_queue']=request_queue else: time0=request_queue[0] if (now-time0)<1: time.sleep(5) request_queue.append(time.time()) request.session['request_queue']=request_queue[1:]
#启用RequestBlocking中间件 IDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'app.middleware.RequestBlockingMiddleware', #在sessions之后，auth之前 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ]
