Adding header with value django cores

Question

According to the django-cors-header documentation in order to add custom headers you add:

  CORS_ALLOW_HEADERS = default_headers + ('my-custom-header',)

To your settings.py , question is how do you add my-custom-header along with it's value to settings.py.

Answer 1

CORS_ALLOW_HEADERS is a list of headers that can be used while making actual request

Following setting does not set header values that can be used, just headers that can be used in requests

Also content-type is already in default_headers so it doesn't need to be set as extra

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