[Django]-Custom HTTP Header in Django

Finally I found just get it through

request.META('HTTP_{your uppercased header name}')

You can add your own custom headers to a response like so:
https://docs.djangoproject.com/en/dev/ref/request-response/#setting-headers

>>> response = HttpResponse()
>>> response['Cache-Control'] = 'no-cache'
>>> del response['Cache-Control']

Or use a decorator to add them to a view:
http://djangosnippets.org/snippets/275/

I was trying to access the header with the above answers, using this code:

request.META.get('HTTP_{your uppercased header name}')

But It didn’t work for me, and then I realized that the custom header should not contain underscore so I changed the underscore with dash and boom, everything started working. Hope this will help people like me. 🙂

As of Django 2.2 you can use the HttpRequest.headers dictionary which provides case-insensitive dictionary of request headers, like such:

my_header = request.headers.get('x-my-custom-header')

See django.http.HttpRequest.headers

From the Django documentation:

https://docs.djangoproject.com/en/2.1/ref/request-response/#django.http.HttpRequest.META

With the exception of CONTENT_LENGTH and CONTENT_TYPE, as given above,
any HTTP headers in the request are converted to META keys by
converting all characters to uppercase, replacing any hyphens with
underscores and adding an HTTP_ prefix to the name. So, for example,
a header called X-Bender would be mapped to the META key
HTTP_X_BENDER.
