Is there any other elegant way to add header to requests :

import requests

requests.get(url,headers={'Authorization', 'GoogleLogin auth=%s' % authorization_token})

doesn't work, while urllib2 worked :

import urllib2

request = urllib2.Request('http://maps.google.com/maps/feeds/maps/default/full')
request.add_header('Authorization', 'GoogleLogin auth=%s' % authorization_token)
urllib2.urlopen(request).read()

  • that's not dictionary syntax at all... – nthall Jun 14 '15 at 17:44

You can add headers by passing a dictionary as an argument.

This should work:

requests.get(url,headers={'Authorization': 'GoogleLogin auth=%s' % authorization_token})

Why your code not worked?

You were not passing a dictionary to the headers argument. You were passing values according to the format defined in add_header() function.

According to docs,

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

headers – (optional) Dictionary of HTTP Headers to send with the Request.

Why request.add_header() worked?

Your way of adding headers using request.add_header()worked because the function is defined as such in the urllib2 module.

Request.add_header(key, val)

It accepts two arguments -

  1. Header name (key of dict defined earlier)
  2. Header value(value of the corresponding key in the dict defined earlier)

You can pass dictionary through headers keyword. This is very elegant in Python :-)

 headers = {
     "header_name": "header_value",
 }

 requests.get(url, headers=headers)

You can add custom headers to a requests request using the following format which uses a Python dictionary having a colon, :, in its syntax.

r = requests.get(url, headers={'Authorization': 'GoogleLogin auth=%s' % authorization_token})

This is presented in the Requests documentation for custom headers as follows:

>>> url = 'https://api.github.com/some/endpoint'
>>> headers = {'user-agent': 'my-app/0.0.1'}

>>> r = requests.get(url, headers=headers)

Headers should be a dict, thus this should work

headers= {}
headers['Authorization']= 'GoogleLogin auth=%s' % authorization_token

requests.get(url, headers=headers)
