Here, however, instead of sending the response from the access token request directly to a browser for redirection, we pull, in our code, the "Location" header off of the HTTP response from the access token request (this is the redirect). This "Location" header contains a URL with a query string containing the access token. Once we have this, we can turn around and make the request for an authorization code using the access token. 11 | 12 | So instead of the browser propagating the access token from OAuth to our third-party app for us, we simply examine the HTTP response ourselves in code. 13 | -------------------------------------------------------------------------------- /oauth_example.py: -------------------------------------------------------------------------------- 1 | import urllib, urllib2, urlparse 2 | 3 | # This sample shows how to obtain a Bullhorn OAuth access token 4 | # without the user/browser flow.
