I’m working in some automation and one of the things I needed to solve was a script to download JIRA attachments with Python, here’s how I did it.
Using the REST API of JIRA and some python modules:
We start defining the she-bang, author, modules and variables that we’ll need before:
#!/usr/bin/python # miguel ortiz # Requests module: http://docs.python-requests.org/en/latest/ # Documentation: <url> # ----------------------------------- modules import sys import csv, json import requests # ---------------------------------- variables myTicket = sys.argv # Your ticket: ABC-123 user = 'miguel' # JIRA user pasw = 'mypassword' # JIRA password jiraURL = 'https://yourinstance.jira.com/rest/api/latest/issue/' fileName = 'my_attached_file' # In this case we'll be looking for a specific file in the attachments attachment_final_url="" # To validate if there are or not attachments
Using ‘requests’ to perform the connection to JIRA:
def main() : print '\n\n [ You are checking ticket: ' + myTicket + ' ]\n' # Request Json from JIRA API r = requests.get('jiraURL+myTicket, auth=(user, pasw),timeout=5) # status of the request rstatus = r.status_code # If the status isn't 200 we leave if not rstatus == 200 : print 'Error accesing JIRA:' + str(rstatus) exit() else: rlinkdata = rlink.json() data = r.json()
Now we validate if there are attachments and if our desired attachment is present and then form the URL of the attachment to be downloaded:
if not data['fields']['attachment'] : status_attachment_name = 'ERROR: Nothing attached, attach a file named: ' + fileName attachment_final_url="" else: for i in data['fields']['attachment'] : if i['filename'] == fileName : attachment_final_url = i['content'] status_attachment_name = 'OK: The desired attachment exists: ' + fileName attachment_name = False attachment_amount = False attachment_files = False break else : attachment_files = False status_attachment_name = 'ERROR: None of the files has the desired name ' attachment_final_url="" attachment_name = True attachment_amount = True continue
Once we validated the file is present we download it (I’ve added UTF8 support because of my specific needs):
if attachment_final_url != "" : r = requests.get(attachment_final_url, auth=(user, pasw), stream=True) with open(fileName, "wb") as f: f.write(r.content.decode('iso-8859-1').encode('utf8')) f.close() if __name__ == "__main__" : main()
And that’s it.
