Need help with Atlassian Jira Python library on Data Centre

Stephen Ellwood

I have been using the Atlassian Python api library now for a couple of years on our Cloud instance and have managed to make it work quite well.  

We are going to migrate to the Datacentre version so I have just tried the same code on there and it does not work.

I created a token and it seems to authorize me ok but whenever I use any class methods of the jira object it comes back with:

HTTPError: Unauthorized (401)

I can see the project and do the same search from my browser window.  Does anyone else have experience of using this Library on a data centre Jira instance?

With the help of my IT department I was able to work out how to make it work.  The confusion came because the Jira instantiation call did not throw an error even though the authentication failed.

It turns out that the authentication is quite different between cloud and data center. The cloud uses a username + password (which is actually a token) and the Data Centre uses only a token passed using the keyword token.

I wrote a general function to open the instance based on the login information contained in a file.

def open_jira(wiki_id):
"""Open Jira instance with the credentials given

Args:
----
wiki_id: textfile containing URL and login information for the needed Jira
first line is "url <url of jira instance> <DC|Cloud>"
second line is:
for DC: "token <valid token for instance>"
for Cloud: "pass email.address@company.com:token"
"""
try:
    with open(wiki_id, 'r') as f:
        url_txt = f.readline().replace("\n", "")
        id_txt = f.readline()
except FileNotFoundError:
    raise LookupError(f'check {wiki_id} is present')

try:
    tag, instance, instance_type = url_txt.split(' ')
    assert tag == "url", "keyword url is missing"
    assert instance_type in ['DC', 'Cloud'], f'{instance_type}: only DC and Cloud allowed'
except:
    raise LookupError(f'check url line in {wiki_id}')

try:
    if instance_type == 'DC':
        tag, pat = id_txt.split(' ')
        assert tag == 'token'
        handle = Jira(url=instance, token=pat)
    else:
        assert ' ' in id_txt and ':' in id_txt, 'password file has wrong format'
        name, token = id_txt.split(' ')[-1].strip().split(':')
        handle = Jira(url=instance, username=name, password=token)
except:
    raise LookupError(f'check credentials in {wiki_id}')

return instance, handle

Hope this helps anyone else having the same issue.
