django限制访问频率，对用户访问频次进行限流（非DRF的throttle）

首先，网上看了很多访问频率限制的教程，都是针对Django REST Framework（DRF）的使用的throttle，对于普通的Django项目做访问频率限制的很少，所以有了这篇文章。

使用前请先安装 django-throttle-requests模块

pip install -i https://pypi.douban.com/simple django-throttle-requests

一、先在Django项目的settings.py文件中定义访问频率限制的规则

THROTTLE_ZONES = {
    # 限制请求频率 10次/分
    'default': {
        'VARY':'throttle.zones.RemoteIP',
        'NUM_BUCKETS':2,  # Number of buckets worth of history to keep. Must be at least 2
        'BUCKET_INTERVAL':1 * 60,  # Period of time to enforce limits.
        'BUCKET_CAPACITY':10,  # Maximum number of requests allowed within BUCKET_INTERVAL
    },
    # 限制请求频率 50次/小时
    'order': {
            'VARY':'throttle.zones.RemoteIP',
            'NUM_BUCKETS':2,  # Number of buckets worth of history to keep. Must be at least 2
            'BUCKET_INTERVAL':60 * 60,  # Period of time to enforce limits.
            'BUCKET_CAPACITY':50,  # Maximum number of requests allowed within BUCKET_INTERVAL
        },
}

THROTTLE_BACKEND = 'throttle.backends.cache.CacheBackend'

# Force throttling when DEBUG=True
THROTTLE_ENABLED = True

二、在视图views.py文件中使用，既可以对FBV（函数视图）使用也可以用在CBV（类视图）上

views.py

from django.views import View
from django.http import JsonResponse
from django.utils.decorators import method_decorator
from throttle.decorators import throttle

from .models import Blog

# 在普通FBV上使用，指定default
@throttle(zone='default')
def bloginfo(request):
    blog = Blog.objects.get(pk=1)
    return JsonResponse({"name": blog.name}, )


class BlogView(View):
    # 装饰在CBV内部的get方法上
    @method_decorator(throttle(zone='default'))
    def get(self, request):
        blog = Blog.objects.get(pk=1)
        return JsonResponse({"name": blog.name})

# 装饰在CBV的类上，用name指定对哪个方法使用throttle
@method_decorator(throttle(zone='default'), name='get')
class BlogView2(View):
    def get(self, request):
        blog = Blog.objects.get(pk=1)
        return JsonResponse({"name": blog.name})

    def post(self, request):
        return JsonResponse({"name": 'name'})

urls.py

from django.urls import path, include

from . import views

urlpatterns = [
    path('bloginfo/', views.bloginfo),
    path('blogview/', views.BlogView.as_view()),
    path('blogview2/', views.BlogView2.as_view()),
]

正常访问

当超过限制访问的频率时就会返回403

pycharm输出
