Description

REST (Representational State Transfer) is a web based software architectural style consisting of a set of constraints that focuses on a system's resources. The Redfish library performs the basic HTTPS operations GET, POST, PUT, PATCH and DELETE on resources using the HATEOAS (Hypermedia as the Engine of Application State) Redfish architecture. API clients allow you to manage and interact with the system through a fixed URL and several URIs. Go to the wiki for more details.

Installing

pip install redfish

Building from zip file source

python setup.py sdist --formats=zip (this will produce a .zip file)
cd dist
pip install python-redfish-library-x.x.x.zip

Requirements

Ensure the system does not have the OpenStack "python-redfish" module installed on the target system. This module is using a conflicting package name that this library already uses. The module in question can be found here: https://pypi.org/project/python-redfish/

Usage

A set of examples is provided under the examples directory of this project. In addition to the directives present in this paragraph, you will find valuable implementation tips and tricks in those examples.

Import the relevant python module

For a Redfish compliant application import the relevant python module.

For Redfish compliant application:

import redfish

Create a Redfish Object

The Redfish Objects contain 3 parameters: the target secured URL (i.e. "https://IP" or "https://X.Y.Z.T"), an user name and its password. To crete a Redfish Object, call the redfish_client method:
REDFISH_OBJ = redfish.redfish_client(base_url=login_host, username=login_account, \
                  password=login_password, default_prefix='/redfish/v1')

Login to the server

The login operation is performed when creating the REDFISH_OBJ. You can continue with a basic authentication, but it would less secure.
REDFISH_OBJ.login(auth="session")

Perform a GET operation

A simple GET operation can be performed to obtain the data present in any valid path. An example of rawget operation on the path "/redfish/v1/systems/1 is shown below:
response = REDFISH_OBJ.get("/redfish/v1/systems/1", None)

Logout the created session

Make sure you logout every session you create as it will remain alive until it times out.
       REDFISH_OBJ.logout()

A logout deletes the current sesssion from the system. The redfish_client object destructor includes a logout statement.
