django解决网站CORS前后端跨域问题

1.安装cors-headers⼯具

  pip install django-cors-headers

2.安装cors-headers应⽤

# 注册应用
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'corsheaders',  # 解决跨域CORS


]

3.配置中间件（cors放在所有中间件的最外层，这样可以第一时间被检测，避免无意义的操作）

# 中间件
MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware',  # 最外层的中间件

    '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',
]

4.添加⽩名单

# 允许哪些域名访问Django
ALLOWED_HOSTS = ['127.0.0.1', 'localhost']

# CORS 追加⽩名单
CORS_ORIGIN_WHITELIST = (
    'http://127.0.0.1:5500',
    'http://localhost:5500',
)
CORS_ALLOW_CREDENTIALS = True  # 跨域时允许携带cookie
