https://github.com/ottoyiu/django-cors-headers

• Setup
  Install from pip:

pip install django-cors-headers
and then add it to your installed apps:

• settings

INSTALLED_APPS = (
    ...
    'corsheaders',
    ...
)
You will also need to add a middleware class to listen in on responses:

MIDDLEWARE = [  # Or MIDDLEWARE_CLASSES on Django < 1.10
    ...
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    ...
]

CORS_ORIGIN_WHITELIST = (
    'google.com',
    'hostname.example.com',
    'localhost:8000',
    '127.0.0.1:9000'
)
