dolmen.authentication 0.3

概述

dolmen.authentication提供接口和组件：

>>> import dolmen.authentication
>>> from dolmen.authentication import IAuthenticationInterfaces
>>> from dolmen.authentication import IAuthenticationEvents
>>> from dolmen.authentication import IAuthenticationAPI

>>> IAuthenticationAPI.isOrExtends(IAuthenticationInterfaces)
True

>>> IAuthenticationAPI.isOrExtends(IAuthenticationEvents)
True

>>> from zope.interface.verify import verifyObject
>>> verifyObject(IAuthenticationAPI, dolmen.authentication)
True

描述性接口

dolmen.authentication提供了一组基本接口，可以是 用于规范化身份验证系统：

>>> print IAuthenticationInterfaces.__doc__
This interface describes and exposes the meaningful interfaces
of the authentication module.

>>> interfaceDescription(IAuthenticationInterfaces)
IPrincipalFolder: A container specialized in storing principal representations.
IAccountStatus: Abstraction component allowing to check the status of a principal.
IPrincipal: A principal representation, directly inheriting from zope.security IPrincipal, but redefining several fields for a user-friendly form display.
IGroup: A logical grouping of principals. This component is an IPrincipal itself.
IPasswordProtected: This interface defines any component protected by a password
IPasswordChecker: Abstraction component in charge of resolving a principal'scredentials.

>>> IAuthenticationInterfaces.providedBy(dolmen.authentication.interfaces)
True

>>> verifyObject(IAuthenticationInterfaces, dolmen.authentication.interfaces)
True

事件接口和实现

dolmen.authentication提供了一组基本事件，可以是 使用和拒绝，以便处理和跟踪主体的生命周期：

>>> print IAuthenticationEvents.__doc__
This interface describes and exposes the meaningful events
descriptions and components of the authentication module.

>>> interfaceDescription(IAuthenticationEvents)
IUserLoggedOutEvent: IObjectEvent extending event : a user has logged out.
IUserLoggedInEvent: IObjectEvent extending event : a user has logged in.
UserLogoutEvent: An IUserLoggedOutEvent implementation.
UserLoginEvent: An IUserLoggedInEvent implementation.

>>> IAuthenticationEvents.providedBy(dolmen.authentication.events)
True

>>> verifyObject(IAuthenticationEvents, dolmen.authentication.events)
True

主要相关成分

最后，dolmen.authentication提供可用于 与zope.pluggableauth交互。

>>> from zope.location import ILocation
>>> from dolmen.authentication import LocatablePrincipalInfo

>>> 'LocatablePrincipalInfo' in IAuthenticationAPI
True

>>> ILocation.implementedBy(LocatablePrincipalInfo)
True

>>> from zope.interface import implements

>>> class User(object):
...   implements(dolmen.authentication.IPrincipal)
...
...   def __init__(self, id, title):
...     self.id = id
...     self.title = title
...     self.description = u"A test user"
...     self.groups = []

>>> myuser = User('Manfred', u"A nice mammoth")

>>> verifyObject(dolmen.authentication.IPrincipal, myuser)
True

>>> from zope.pluggableauth.interfaces import IPrincipalInfo
>>> adapter = IPrincipalInfo(myuser)

>>> adapter
<dolmen.authentication.principal.LocatablePrincipalInfo ...>

>>> IPrincipalInfo.providedBy(adapter)
True

>>> print adapter.__name__
None
>>> print adapter.__parent__
None

>>> from zope.interface import alsoProvides

>>> class MyParent(object):
...   pass

>>> myuser.__name__ = u"Manfred the mammoth"
>>> myuser.__parent__ = MyParent()
>>> alsoProvides(myuser, ILocation)

>>> adapter = IPrincipalInfo(myuser)

>>> print adapter.__name__
Manfred the mammoth
>>> print adapter.__parent__
<dolmen.authentication.MyParent object at ...>
