title: OAuth 1.0 - how to pass token in headers?
body: <p>There's a website require OAuth 1.0 and is requiring using a token. I tried the code:</p>
  
  <pre><code>def request(path=None):
      token = access_token()
      headers = { 'Authorization' : 'oauth_token %s' %  token }
      res = requests.get('https://somewebsite.com/v1'+path, headers=headers)
      print res.text
  </code></pre>
  
  <p>or replace <code>oauth_token</code> with, <code>access_token</code> or <code>TOK:</code>. They just didn't work, which returns error <code>Access_token is empty</code>. Is authentication method all different with various sites?</p>
