linkahead.connection.authentication.interface module

This module provides the interfaces for authenticating requests to the LinkAhead server.

Implementing modules muts provide a get_authentication_provider() method.

class linkahead.connection.authentication.interface.AbstractAuthenticator

Bases: ABC

AbstractAuthenticator.

Interface for different authentication mechanisms. e.g. username/password authentication or SSH key authentication.

logger

A logger which should be used for all logging which has to do with authentication.

Type:: Logger

auth_token

A string representation of a LinkAhead Auth Token.

Type:: str

login(abstract)

logout(abstract)

configure(abstract)

on_request()

on_response()

abstract configure(**config)

configure.

Configure this authenticator.

Parameters:: **config – Keyword arguments for the configuration.
Return type:: None

abstract login()

login.

To be implemented by the child classes.

Return type:: None

abstract logout()

logout.

To be implemented by the child classes.

Return type:: None

on_request(method, path, headers, **kwargs)

on_request.

A call-back which is to be called by the connection before each request. This method set the auth cookie for that request.

Parameters:

method (str) – The request method.
path (str) – The request path.
headers (dict) – A dictionary with headers which are to be set.
**kwargs – Ignored

on_response(response)

on_response.

A call-back with is to be called by the connection after each response. This method reads the latest auth cookie from the response.

Parameters:: response (CaosDBHTTPResponse) – The response of the server

class linkahead.connection.authentication.interface.CredentialsAuthenticator(credentials_provider)

Bases: AbstractAuthenticator

CredentialsAuthenticator.

Subclass of AbstractAuthenticator which provides authentication via credentials (username/password). This class always needs a credentials_provider which provides valid credentials_provider before each login.

Parameters:: credentials_provider (CredentialsProvider) – The source for the username and the password.

login()

logout()

configure()

configure(**config)

configure.

Configure this authenticator.

Parameters:: **config – Keyword arguments for the configuration.
Return type:: None

login()

login.

To be implemented by the child classes.

Return type:: None

logout()

logout.

To be implemented by the child classes.

Return type:: None

class linkahead.connection.authentication.interface.CredentialsProvider

Bases: ABC

CredentialsProvider.

An abstract class for username/password authentication.

password(abstract)

username(abstract)

logger

A logger which should be used for all logging which has to do with the provision of credentials. This is usually just the “authentication” logger.

Type:: Logger

configure(abstract)

abstract configure(**config)

configure.

Configure the credentials provider with a dict.

Parameters:: **config – Keyword arguments. The relevant arguments depend on the implementing subclass of this class.
Return type:: None

abstract property password: password.

abstract property username: username.
