Getting custom header on post request with django rest framework

The name of the meta data attribute of request is in upper case:

print request.META

Your header will be available as:

request.META['HTTP_X_MYHEADER']

Or:

request.META.get('HTTP_X_MYHEADER') # return `None` if no such header

Quote from the documentation:

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.

If you provide a valid header information and get that information from backend then follow those

client-name='ABCKD'

then you have get that client information in post or get function following this-

request.META['HTTP_CLIENT_NAME']

it will give you output 'ABCKD'.

remember that, whatever the valid variable name you provide in your header information in request, django convert it uppercase and prefix with 'HTTP_' in here it will client-name converted to CLIENT_NAME and prefix with HTTP_. so final output is HTTP_CLIENT_NAME
