REST_FRAMEWORK 配置
对使用 rest_framework 框架的项目来说,可以使用框架的设置来对api的访问频率进行限制
REST_FRAMEWORK = {
'DEFAULT_PARSER_CLASSES': (
'rest_framework.parsers.JSONParser',
'rest_framework.parsers.FormParser',
'rest_framework.parsers.MultiPartParser',
),

}
使用middleware中间件来限制IP频率
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',
'common.middleware.RequestBlockingMiddleware', #在sessions之后,auth之前
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
以上这篇Django 对IP访问频率进行限制的例子就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持脚本之家。
