Auth | Authorization for Humans¶
RESTful, Simple Authorization system with ZERO configuration.
What is Auth?¶
Auth is a module that makes authorization simple and also scalable and powerful. It also has a beautiful RESTful API for use in micro-service architectures and platforms. It is originally desinged to use in Appido, a scalable media market in Iran.
It supports Python2.6+ and if you have a mongodb backbone, you need ZERO configurations steps. Just type
auth-server and press enter!
I use Travis and Codecov to keep myself honest.
You need to access to mongodb. If you are using a remote mongodb, provide these environment variables:
pip install auth
Show me an example¶
ok, lets image you have two users, Jack and Sara. Sara can cook and Jack can dance. Both can laugh.
You also need to choose a secret key for your application. Because you may want to use Auth in various tools and each must have a secret key for seperating their scope.
my_secret_key = "pleaSeDoN0tKillMyC_at" from auth import Authorization cas = Authorization(my_secret_key)
Now, Lets add 3 groups, Cookers, Dancers and Laughers. Remember that groups are Roles. So when we create a group, indeed we create a role:
cas.add_role('cookers') cas.add_role('dancers') cas.add_role('laughers')
Ok, great. You have 3 groups and you need to authorize them to do special things.
cas.add_permission('cookers', 'cook') cas.add_permission('dancers', 'dance') cas.add_permission('laughers', 'laugh')
Good. You let cookers to cook and dancers to dance etc… The final part is to set memberships for Sara and Jack:
cas.add_membership('sara', 'cookers') cas.add_membership('sara', 'laughers') cas.add_membership('jack', 'dancers') cas.add_membership('jack', 'laughers')
That’s all we need. Now lets ensure that jack can dance:
if cas.user_has_permission('jack', 'dance'): print('YES!!! Jack can dance.')
use pydoc to see all methods:
Lets run the server on port 4000:
from auth import api, serve serve('localhost', 4000, api)
Or, from version 0.1.2+ you can use this command:
Simple! Authorization server is ready to use.
You can use it via simple curl or using mighty Requests module. So in you remote application, you can do something like this:
import requests secret_key = "pleaSeDoN0tKillMyC_at" auth_api = "http://127.0.0.1:4000/api"
Lets create admin group:
And lets make Jack an admin:
And finally let’s check if Sara still can cook:
RESTful API helpers¶
auth comes with a helper class that makes your life easy.
from auth.client import Client service = Client('srv201', 'http://192.168.99.100:4000') print(service) service.get_roles() service.add_role(role='admin')
Ping API, useful for your monitoring tools
Adding, removing and getting membership information.
Adding, removing and getting permissions
Getting user permission info
Adding, removing and getting roles
For example: Which roles can send_mail?
For example: Which users can send_mail?
Get all permissions that a user has
Get all permissions that a role has
Get roles that user assinged to
Get all available roles
Deploying Auth module in production environment is easy:
docker build -t python/auth-server https://raw.githubusercontent.com/ourway/auth/master/Dockerfile docker run --name=auth -e MONGO_HOST='192.168.99.100' -p 4000:4000 -d --restart=always --link=mongodb-server python/auth-server
Feel free to dig into source code. If you think you can improve the documentation, please do so and send me a pull request.
Unit Tests and Coverage¶
I am trying to add tests as much as I can, but still there are areas that need improvement.
- Add Authentication features
- Improve Code Coverage
