etunexus

Etunexus is an GPL-licensed SDK encapsulating the API to interact with etunexus online service.

It supports API of Etu Management Center (EMC) v2, Etu Recommender (ER) v3, and Etu Insight (EI) v3.

Features

• Simplify the single-signon process with a simple login() call.
• Encapsulate the protocol detail into easy-of-use objects, but still keep the flexibility for adjustment.

Quick start

Etuneuxs online service provides a rich and full-featured API entries for every client supporting RESTful programming model to manipulate the data and settings. It also provides a single-sign-on (SSO) service that multiple applications can share the same user login authentication.

However, for a Python programmer, it is still complicated to code the SSO process with involving two stages communication between SSO server and application server from the ground. The SDK wraps it as a simple login() call as:

>>> from etunexus.cas import *
>>> from etunexus.emc import *
>>>
>>> cas = CAS([user_group], [user_name], [password])
>>> # It is optional to make SSO login first.
>>> cas.login()
'TGT-147-ZRV9j9fy2mv2wZujOKMyaFlOeKXJqvf9S6jBcWeJ39vb1TzKaY-cas.etu.im'
>>>
>>> # Login application
>>> emc2 = EMC2(cas)
>>> emc2.login()
'ST-232-wUwi0bNFhB66Xxr4wM7o-cas.etu.im'

The subsequent API call is also trivial with the methods of the application object. For example, it is easy to get the group list and the user list in a group (of course, for an authorized account only) with:

>>> # Get all groups, and then find a specific group.
>>> groups=emc2.get_groups()
>>> workshop_group = filter(lambda x: x['name']=='workshop', groups)[0]
>>> print workshop_group
{'id': 2, 'displayName': u'Workshop Sample', 'name': u'workshop', 'createTime': 1484113449499}
>>>
>>> # Get all users, and then find a specific user
>>> workshop_users = emc2.get_users(workshop_group)
>>> workshop_user = filter(lambda x: x['name']=='workshop_user', workshop_users)[0]
>>> print workshop_user
{'displayName': u'Workshop User', 'name': u'workshop_user', 'roles': [{'roleName': u'Operator', 'appId': u'ETU-INSIG
HT'}, {'roleName': u'Viewer', 'appId': u'ETU-RECOMMENDER'}], 'lastUpdateTime': 1487399443855, 'createTime': 14841296
56168, 'department': u'', 'mail': u'', 'password': None, 'id': 3}

It is worthy of noticing that the data returned are wrapped into objects/classes:

>>> type(workshop_group)
<class 'etunexus.emc.Group'>
>>> type(workshop_user)
<class 'etunexus.emc.User'>

To manipulate the data, for example, add a user to the group. First, create an object as the data with the constructor already properly designed:

>>> new_user=User('new_workshop_user', 'New workshop user', 'password')
>>> emc2.add_user(workshop_group, new_user)
{'createTime': 1487735435494, 'department': u'', 'displayName': u'New workshop user', 'id': 15, 'lastUpdateTime': 14
87735435494, 'mail': u'', 'name': u'new_workshop_user', 'password': None, 'roles': []}

And, it is easy to update the data with:

>>> update_user = filter(lambda x: x['name']=='new_workshop_user', workshop_users)[0]
>>>
>>> from etunexus.enum import *
>>> update_user['roles']=[UserRole(AppRoleName.VIEWER, AppId.ER), UserRole(AppRoleName.VIEWER, AppId.EI)]
>>>
>>> emc2.update_user(update_user)
{'createTime': 1487735435494, 'department': u'', 'displayName': u'New workshop user', 'id': 15, 'lastUpdateTime': 14
87736051534, 'mail': u'', 'name': u'new_workshop_user', 'password': None, 'roles': [{'appId': u'ETU-RECOMMENDER', 'r
oleName': u'Viewer'}, {'appId': u'ETU-INSIGHT', 'roleName': u'Viewer'}]}

Finally, delete a resource is also as simple as:

>>> emc2.del_user(update_user)
15

Similar programming model for other applications (ER and EI). Please refer to pydoc for detail. There are also samples in GitHub repository.

Installation

Etunexus is in PyPI. It can be installed easily directly with:

$ pip install etunexus

Or, from Github:

$ git clone https://github.com/etusolution/etunexus_api.git
$ cd etunexus_api/module
$ python setup.py install

Documents generation

After installed the SDK, the document of modules can be viewed with following:

$ pydoc etunexus.emc
$ pydoc etunexus.er
$ pydoc etunexus.ei
$ pydoc etunexus.enum

Or, you can generate the HTML edition with "pydoc -w". For example, following line generate an etunexus.emc.html.

$ pydoc -w etunexus.emc
