twisted.web.guard.HTTPAuthSessionWrapper : API documentation

Wrap a portal, enforcing supported header-based authentication schemes.

Instance Variables	_portal	The `Portal` which will be used to retrieve `IResource` avatars.
	_credentialFactories	A list of `ICredentialFactory` providers which will be used to decode Authorization headers into `ICredentials` providers.

Method	__init__	Initialize a session wrapper
Method	render	Find the `IResource` avatar suitable for the given request, if possible, and render it. Otherwise, perhaps render an error page requiring authorization or describing an internal server failure.
Method	getChildWithDefault	No summary
Method	_authorizedResource	No summary
Method	_login	Get the `IResource` avatar for the given credentials.
Method	_loginSucceeded	Handle login success by wrapping the resulting `IResource` avatar so that the `logout` callback will be invoked when rendering is complete.
Method	_loginFailed	Handle login failure by presenting either another challenge (for expected authentication/authorization-related failures) or a server error page (for anything else).
Method	_selectParseHeader	Choose an `ICredentialFactory` from `_credentialFactories` suitable to use to decode the given Authenticate header.

def __init__(self, portal, credentialFactories): (source)

Initialize a session wrapper

Parameters	portal	The portal that will authenticate the remote client (type: `Portal` )
	credentialFactories	The portal that will authenticate the remote client based on one submitted `ICredentialFactory` (type: `Iterable` )

def _authorizedResource(self, request): (source)

Get the IResource which the given request is authorized to receive. If the proper authorization headers are present, the resource will be requested from the portal. If not, an anonymous login attempt will be made.

def render(self, request): (source)

from twisted.web.resource.IResource

Find the IResource avatar suitable for the given request, if possible, and render it. Otherwise, perhaps render an error page requiring authorization or describing an internal server failure.

def getChildWithDefault(self, path, request): (source)

from twisted.web.resource.IResource

Inspect the Authorization HTTP header, and return a deferred which, when fired after successful authentication, will return an authorized Avatar. On authentication failure, an UnauthorizedResource will be returned, essentially halting further dispatch on the wrapped resource and all children

def _login(self, credentials): (source)

Get the IResource avatar for the given credentials.

Returns A Deferred which will be called back with an IResource avatar or which will errback if authentication fails.

def _loginSucceeded(self, (interface, avatar, logout)): (source)

Handle login success by wrapping the resulting IResource avatar so that the logout callback will be invoked when rendering is complete.

def _selectParseHeader(self, header): (source)

Choose an ICredentialFactory from _credentialFactories suitable to use to decode the given Authenticate header.

Returns A two-tuple of a factory and the remaining portion of the header value to be decoded or a two-tuple of None if no factory can decode the header value.
