title: Authorization header in Requests package in python
body: <p>I am trying write a python script using requests package to use an online mongodb query service API hosted within the organization. The API expects the authorization header in the format 'websitename/username:Password' and using the basic authentication base64 encoding. I tried to create the GET request using the  requests package which has the authorization header in the following format:</p>
  
  <pre><code>import requests
  
  headers = {'Authorization': 'Basic %s' % 'Base64encoded 
  websitename/username:Password string here'}
  
  content_res = requests.get(get_url, headers = headers).json()
  </code></pre>
  
  <blockquote>
    <p>But I am getting a parse error here for the string as I think the expected string for header in requests package is in form of 'username:password' here and not the desired format i.e. 'websitename/username:password'.</p>
  </blockquote>
  
  <p>Is there a way in which I could use the base64 encoded sting in the format which the service is expecting i.e. 'websitename/username:password' in requests package?</p>
  
  <p>Any help is highly appreciated.</p>
  
  <p>Thanks.</p>
