...
]

# 添加中间件

MIDDLEWARE = [

'django.middleware.security.SecurityMiddleware',

'django.contrib.sessions.middleware.SessionMiddleware',

'corsheaders.middleware.CorsMiddleware',# 新增

'django.middleware.common.CommonMiddleware',

'django.middleware.csrf.CsrfViewMiddleware',

'django.contrib.auth.middleware.AuthenticationMiddleware',

'django.middleware.clickjacking.XFrameOptionsMiddleware',

]

# 跨域增加忽略
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_ALLOW_ALL = True
CORS_ORIGIN_WHITELIST = ('*'）  #可加可不加

 

 

CORS_ALLOW_METHODS = (
'DELETE',
