Excerpt

If you are writing a script that interacts with Jira through a REST API, you should authenticate using an OAuth token, rather than an embedded username/password. Here we describe one way to do the 'oauth dance' to generate a trusted token using Python 3 - specifically the jirashell  utility from the jira Python package.  jirashell  then forms a useful basis for a Python script. Our example script uses OAuth to call an undocumented REST API for querying license data.


Warning

These instructions no longer work for me on tested combinations {Ubuntu 18.04 + Python 3.6.9}, { Ubuntu 20.04 + Python 3.8.5}. The jirashell command should print a URL, but instead returns:

Code Block
'oauth_token'

titleGetting 'oauth_token' instead of a URL?

If, instead of printing a URL, the jirashell command just prints:

Code Block
'oauth_token'

That means your consumer-key does not exist in Jira (perhaps you copy & pasted the example without substituting yours?). This is an error reporting bug in jirashell.

titleWhy BROWSER='echo %s'..

Jirashell would normally try to launch your preferred web browser, using the webbrowser library. By setting the BROWSER env variable, we tell Python not to bother, and just print the URL for us to manually cut & paste. This is required for server environments, where lynx isn't able to deal with Jira's Javascript.
