Using headers with the Python requests library’s get method

So I recently stumbled upon this great library for handling HTTP requests in Python; found here http://docs.python-requests.org/en/latest/index.html.

I love working with it, but I can’t figure out how to add headers to my get requests. Help?

Method 1

According to the API, the headers can all be passed in with requests.get():

import requests
r=requests.get("http://www.example.com/", headers={"Content-Type":"text"})

Method 2

Seems pretty straightforward, according to the docs on the page you linked (emphasis mine).

requests.get(url, params=None, headers=None, cookies=None, auth=None,
timeout=None)

Sends a GET request.
Returns Response object.

Parameters:

• url – URL for the new
  Request object.
• params – (optional)
  Dictionary of GET Parameters to send
  with the Request.
• headers – (optional)
  Dictionary of HTTP Headers to send
  with the Request.
• cookies – (optional)
  CookieJar object to send with the
  Request.
• auth – (optional) AuthObject
  to enable Basic HTTP Auth.
• timeout –
  (optional) Float describing the
  timeout of the request.

Method 3

This answer taught me that you can set headers for an entire session:

s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})

# both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})

Bonus: Sessions also handle cookies.

Method 4

1. Go to http://myhttpheader.com
2. copy attributes – typically ‘Accept-Language’ and ‘User-Agent’.
3. Wrap them in the dictionary:

   headers = { 'Accept-Language' : content-copied-from-myhttpheader,
               'User-Agent':content-copied-from-myhttpheader}
   

4. pass headers in your request

   requests.get(url=your_url,headers=headers)
