How to Get Header from Request in Django?
Hi Guys,
In this tutorial, you'll learn how to get HTTP headers from a request in Django using simple and effective methods. If you're wondering how to fetch all request headers in Django or specifically retrieve headers like Authorization or User-Agent, this guide provides clear examples for Django 3 and above.
This article also answers the common question — "How can I read headers in a Django view or template?" You'll also learn how Django handles headers case-insensitively, which makes it easier to work with any header format.
Let’s dive into the code example below:
Example:In this step, we will get all header parameters from the request. This includes User-Agent, Authorization, and any custom headers sent with the request.
>>> request.headers
{'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36', ...}
>>> 'User-Agent' in request.headers
True
>>> 'user-agent' in request.headers
True
>>> request.headers['User-Agent']
'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36'
>>> request.headers['user-agent']
'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36'
>>> request.headers.get('User-Agent')
'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36'
>>> request.headers.get('user-agent')
'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36'
Get Django Templates
You can also access request headers inside Django templates using dot notation with underscores instead of hyphens. Here's how to get the User-Agent header:
{{ request.headers.user_agent }}
This is especially useful when you want to conditionally render content based on the user's device or browser.
