django解决跨域请求的问题
方法：1
1、中间件代码
[root@linux-node01 mysite]# tree middlewares
middlewares
├── base.py
├── base.pyc
├── cors.py
├── cors.pyc
├── __init__.py
└── __init__.pyc 0 directories, 6 files
[root@linux-node01 mysite]#
2. 代码结构
middlewares/base.py
[root@linux-node01 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
[root@linux-node01 mysite]#
核心文件middlewares/cors.py
[root@linux-node01 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
[root@linux-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'
]
方法：2
1.安装django-cors-headers
pip install django-cors-headers
2.配置settings.py文件
INSTALLED_APPS = [
'corsheaders',
]
MIDDLEWARE = [
'corsheaders.middleware.CorsMiddleware', #这个放到第一位
]
复制代码
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_ALLOW_ALL = True
CORS_ALLOW_METHODS = (
'DELETE',
'GET',
'OPTIONS',
'PATCH',
'POST',
'PUT',
'VIEW',
)
CORS_ALLOW_HEADERS = (
'XMLHttpRequest',
'X_FILENAME',
'accept-encoding',
'authorization',
'content-type',
'dnt',
'origin',
'user-agent',
'x-csrftoken',
'x-requested-with',
'Pragma',
)
## 白名单，使用'*' 方式好像不能
CORS_ORIGIN_WHITELIST = [
'http://localhost:3000',
'http://localhost:8000',
'http://localhost:8080',
]
复制代码
OK！问题解决！
