How to Get All the Request Headers in Django

How can I get all the request headers in Django?

According to the documentation request.META is a "standard Python dictionary containing all available HTTP headers". If you want to get all the headers you can simply iterate through the dictionary.

Which part of your code to do this depends on your exact requirement. Anyplace that has access to request should do.

Update

I need to access it in a Middleware class but when i iterate over it, I get a lot of values apart from HTTP headers.

From the documentation:

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.

(Emphasis added)

To get the HTTP headers alone, just filter by keys prefixed with HTTP_.

Update 2

could you show me how I could build a dictionary of headers by filtering out all the keys from the request.META variable which begin with a HTTP_ and strip out the leading HTTP_ part.

Sure. Here is one way to do it.

import re
regex = re.compile('^HTTP_')
dict((regex.sub('', header), value) for (header, value) 
       in request.META.items() if header.startswith('HTTP_'))

How can I get data from Django Headers?

As per documentations say https://docs.djangoproject.com/en/2.0/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.

So you should be able to access your header like this

request.META['HTTP_ABCDATA']

Django / Python how to get the full request header?

All the headers are available in request.META. See the documentation.

accessing request headers on django/python

You can access them within a view using request.META, which is a dictionary.

If you wanted the Authorization header, you could do request.META['HTTP_AUTHORIZATION']

If you're creating a restful API from scratch, you might want to take a look at using tastypie.

How to access custom HTTP request headers on Django Rest Framework?

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

print request.META

If your header is called "My-Header", your header will be available as:

request.META['HTTP_MY_HEADER']

Or:

request.META.get('HTTP_MY_HEADER') # 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.

Request Headers within Python Django

request.META is a dict, so if that header is not found, your code will fail with a KeyError. You can either catch that, or use request.META.get('HTTP_X_AUTHTOKEN') instead.

You need to modify your settings.py to allow your frontend to access the service via CORS, make sure to add your correct frontend port:

# Add here your frontend URL
CORS_ALLOWED_ORIGINS = [
    "http://localhost:3000",
]
