Python编程：Django中间件实现登陆验证

Django请求处理图 当然可以使用装饰器，不过不利于维护，还是妥妥的使用中间件

设置 setting.py

MIDDLEWARE = [
    'mymiddlewares.AccessAuthMiddleWare',
]

# 放行url，不进行登录验证
EXCLUDE_URL = [
    "/login"
]

# 用户名密码
USERS = [
    ("username", "password")
]

自定义 mymiddleware.py

import re
from django.shortcuts import redirect
from django.utils.deprecation import MiddlewareMixin
from settings import EXCLUDE_URL, USERS


exclued_path = [re.compile(item) for item in EXCLUDE_URL]


class AccessAuthMiddleWare(MiddlewareMixin):
    """
    访问控制
    """

    def process_request(self, request):
        # 放行
        url_path = request.path
        for each in exclued_path:
            if re.match(each, url_path):
                return None

        # 验证
        user = request.COOKIES.get('user')
        password = request.COOKIES.get('password')
        if (user, password) in USERS:
            return None
        else:
            return redirect('/login')
