dnago前后端分离如何解决跨域请求问题

1.pip install django-cors-headers

2.添加应用

INSTALLED_APPS = ( 
…

'corsheaders', ... 
1
2

) 

3.中间层设置

MIDDLEWARE = [

'corsheaders.middleware.CorsMiddleware', ... 
1
2

] 

4.添加白名单

 （在这里添加后端的ip）

CORS_ORIGIN_WHITELIST = (
‘127.0.0.1:8080’,
‘localhost:8080’,
‘www.meiduo.site:8080’

)
CORS_ALLOW_CREDENTIALS = True # 允许携带cookie
5.设置allowed_hosts
允许所有主机访问 ‘*’
ALLOWED_HOSTS = [‘*’]
