UsernamePasswordWrapper
I bring a twisted.cred
Portal to the web. Use me to
provide different Resources (usually entire pages) based on a user's
authentication details.
A UsernamePasswordWrapper
is a Resource
, and is usually wrapped in a SessionWrapper
before being inserted into
the site tree.
The Realm
associated with your Portal
should be prepared to accept a
request for an avatar that implements the twisted.web.resource.IResource
interface.
This avatar should probably be something like a Woven Page
. That is, it should represent a whole
web page. Once you return this avatar, requests for it's children do not
go through guard.
Portal
has a checker associated that allows
anonymous access. (See twisted.cred.checkers.AllowAnonymousAccess
)

getChild(self, path, request)Retrieve a 'child' resource from me. Implement this to create dynamic resource generation -- resources which are always available may be registered with self.putChild(). This will not be called if the class-level variable 'isLeaf' is set in your subclass; instead, the 'postpath' attribute of the request will be left as a list of the remaining path elements. For example, the URL /foo/bar/baz will normally be:| site.resource.getChild('foo').getChild('bar').getChild('baz').However, if the resource returned by 'bar' has isLeaf set to true, then the getChild call will never be made on it.
