Django django-cors-headers实现防跨域

安装

pip install django-cors-headers

注册应用

INSTALLED_APPS = (
...
'corsheaders',
...
)

中间层设置

MIDDLEWARE = [
    ...
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    ...
]

添加白名单

# CORS 设置跨域域名
CORS_ORIGIN_WHITELIST = (
'127.0.0.1:8080',
'localhost:8080',
'www.xxxx.com:8080',
'api.xxxx.com:8000'
)

CORS_ALLOW_CREDENTIALS = True # 允许携带cookie

ALLOWED_HOSTS = ['www.xxxx.com:8080','api.xxxx.com:8000','127.0.0.1']

# 前端需要携带cookies访问后端时,需要设置
withCredentials: true

设置允许访问的方法( 已测，没用 )

CORS_ALLOW_METHODS = (
'GET',
'POST',
'PUT',
'PATCH',
'DELETE',
'OPTIONS'
)

设置允许的header：（未测）

CORS_ALLOW_HEADERS = (
'x-requested-with',
'content-type',
'accept',
'origin',
'authorization',
'x-csrftoken'
)

安装

pip install django-cors-headers

1 INSTALLED_APPS = (
2   'corsheaders',
3 )

添加中间件

 1 MIDDLEWARE = [
 2     'django.middleware.security.SecurityMiddleware',
 3     'django.contrib.sessions.middleware.SessionMiddleware',
 4     'django.middleware.csrf.CsrfViewMiddleware',
 5     'django.contrib.auth.middleware.AuthenticationMiddleware',
 6     'django.contrib.messages.middleware.MessageMiddleware',
 7     'django.middleware.clickjacking.XFrameOptionsMiddleware',
 8     'corsheaders.middleware.CorsMiddleware',  # 按顺序
 9     'django.middleware.common.CommonMiddleware',  # 按顺序
10 ]

CorsMiddleware应该放置得尽可能高，特别是在可以产生响应的任何中间件之前，如Django CommonMiddleware或Whitenoise WhiteNoiseMiddleware。如果以前没有，则无法将CORS头添加到这些响应中。

配置白名单

 1 CORS_ALLOW_CREDENTIALS = True#允许携带cookie
 2 CORS_ORIGIN_ALLOW_ALL = True
 3 CORS_ORIGIN_WHITELIST = ( '*')#跨域增加忽略
 4 CORS_ALLOW_METHODS = ( 'DELETE', 'GET', 'OPTIONS', 'PATCH', 'POST', 'PUT', 'VIEW', )
 5 #允许的请求头
 6 CORS_ALLOW_HEADERS = (
 7     'XMLHttpRequest',
 8     'X_FILENAME',
 9     'accept-encoding',
10     'authorization',
11     'content-type',
12     'dnt',
13     'origin',
14     'user-agent',
15     'x-csrftoken',
16     'x-requested-with',
17     'Pragma',
18 )

前端项目设置请求头记得添加到CORS_ALLOW_HEADERS
