This is a quick tutorial on how to use R4J's web services using python scripts. The following examples will allow a faster start for users to use the R4J web services.

Requirements

Python 2.7.x https://www.python.org/downloads/
Requests http://docs.python-requests.org/en/master/user/install/

Imports

The import code block used in the examples

# Import the request HTTP library for python 
# Documentation http://docs.python-requests.org/en/master/user/quickstart/ 
import requests 


# Import HTTPBasicAuth to handle the required authentication for the web services 
from requests.auth import HTTPBasicAuth 


# Import json library to process encoding and decoding of JSON responses 
import json

Constant variables

The constant variables used in all the examples. Refer to the comments for the contents and use of this variables.

# the host URL of the JIRA instance, e.g. 'http://localhost:8080' or 'http://example.com' HOST_URL = 'http://example.com' 
HOST_URL = 'http://example.com'

# valid username and password with rights to configure Requirements USERNAME = 'myUsername' PASSWORD = 'myPassword'
USERNAME = 'myUsername'
PASSWORD = 'myPassword'

Requirements endpoint library

The python script file with the collection of all methods used in the examples.

Endpoint library

# Import the request HTTP library for python
# Documentation http://docs.python-requests.org/en/master/user/quickstart/
import requests

# Import HTTPBasicAuth to handle the required authentication for the web services
from requests.auth import HTTPBasicAuth

# Import json library to process encoding and decoding of JSON
import json
