1、中间件代码

[[email protected] mysite]# tree middlewares
middlewares
├── base.py
├── base.pyc
├── cors.py
├── cors.pyc
├── __init__.py
└── __init__.pyc

0 directories, 6 files
[[email protected]-node01 mysite]# 

2. 代码

middlewares/base.py

[[email protected] mysite]# cat middlewares/base.py
#!/bin/env python
# -*- coding: utf-8 -*-
class MiddlewareMixin(object):
    def __init__(self, get_response=None):
        self.get_response = get_response
        super(MiddlewareMixin, self).__init__()

    def __call__(self, request):
        response = None
        if hasattr(self, ‘process_request‘):
            response = self.process_request(request)
        if not response:
            response = self.get_response(request)
        if hasattr(self, ‘process_response‘):
            response = self.process_response(request, response)
        return response
[[email protected]-node01 mysite]# 

核心文件middlewares/cors.py

[[email protected] mysite]# cat middlewares/cors.py
#!/bin/env python
# -*- coding: utf-8 -*-
from .base import MiddlewareMixin


class CORSMiddleware(MiddlewareMixin):
    """CORS中间件"""

    def process_response(self, request, response):
        if request.method == "OPTIONS":
            response[‘Access-Control-Allow-Origin‘] = ‘*‘
            response[‘Access-Control-Allow-Headers‘] = ‘*‘
            response[‘Access-Control-Allow-Methods‘] = ‘*‘
        else:
            response[‘Access-Control-Allow-Origin‘] = ‘*‘
        return response
[[email protected]-node01 mysite]# 

3. settings.py文件配置

MIDDLEWARE = [
    ‘django.middleware.security.SecurityMiddleware‘,
    ‘django.contrib.sessions.middleware.SessionMiddleware‘,
    ‘django.middleware.common.CommonMiddleware‘,
    ‘django.middleware.csrf.CsrfViewMiddleware‘,
    ‘django.contrib.auth.middleware.AuthenticationMiddleware‘,
    ‘django.contrib.messages.middleware.MessageMiddleware‘,
    ‘django.middleware.clickjacking.XFrameOptionsMiddleware‘,
    ‘mysite.middlewares.cors.CORSMiddleware‘
]
