Django 拦截器

创建拦截器后，所有通信都会先走拦截器，然后再去访问urls

django中拦截器的创建

#### setting 中配置
MIDDLEWARE_CLASSES = [
    ‘django.middleware.security.SecurityMiddleware‘,
    ‘django.contrib.sessions.middleware.SessionMiddleware‘,
    ‘django.middleware.common.CommonMiddleware‘,
    ‘django.middleware.csrf.CsrfViewMiddleware‘,
    ‘django.contrib.auth.middleware.AuthenticationMiddleware‘,
    ‘django.contrib.auth.middleware.SessionAuthenticationMiddleware‘,
    ‘django.contrib.messages.middleware.MessageMiddleware‘,
    ‘django.middleware.clickjacking.XFrameOptionsMiddleware‘,
    ‘documents.myMiddleware.FilterMiddleware‘,     # 配置拦截器路径
]

#### myMiddleware 拦截器文件
# -*- coding: utf-8 -*-

from django.http import HttpResponseRedirect,HttpResponse

from django.shortcuts import render
try:
    from django.utils.deprecation import MiddlewareMixin  # Django 1.10.x
except ImportError:
    MiddlewareMixin = object  # Django 1.4.x - Django 1.9.x



class FilterMiddleware(MiddlewareMixin):
    def process_request(self, request):
        print request.path
        # 填上所有不拦截的一级路由
        if request.path.startswith("/xxx") == True or request.path.startswith("/xxx") == True or request.path.startswith("/xxx") == True or request.path.startswith("/xxx") == True or request.path.startswith("/xxx") == True or request.path.startswith("/xxx") == True or request.path.startswith("/xxx") == True:
            pass
        else:
            # return HttpResponse("404")
            return render(request, "xxx/xxx/404.html")
