PluginComponent, java.lang.Comparable<AuthenticationHandler>

public class AuthKeyAuthenticationHandler
extends AuthenticationHandler

Authenticates users using an "authentication key" parameter valid only for the request for which it is processed.

The Authentication key parameter name can be configured by changing property "auth-mgr.authkey-name", see getAuthKeyName().
Default duration of AuthenticationKey can be configured by changing property "auth-mgr.authkey-duration", see getDefaultAuthKeyDuration().

Method Detail

getInstance

public static final AuthKeyAuthenticationHandler getInstance()

loadProperties

public void loadProperties()

Description copied from class: AuthenticationHandler

This method will be called by the AuthenticationManager each time the Channel properties are loaded/reloaded.
You can use it to reload properties that might have been changed.
This method is called during initialization of the AuthenticationManager

Overrides:

loadProperties in class AuthenticationHandler

login

public void login(AuthenticationContext ctxt)
           throws java.io.IOException

Description copied from class: AuthenticationHandler

Authenticate a member.
This method is invoked by the authentication chain on each request.
A typical implementation of this method would follow the following pattern :

1. Examine informations required to perform the authentication through the AuthenticationContext object (request, response, login.. etc)
2. Perform your authentication before chain invokation and set the logged Member AuthenticationContext.setLoggedMember(com.jalios.jcms.Member)
3. a) Either invoke the next entity in the chain using AuthenticationContext.doChain(),
4. b) or else skip the chain invokation and block other authentication handler of the chain (do this with caution...)
5. Perform redirection, set information/warning/error message or any other process, after chain invokation, using AuthenticationContext.

Default implementation is to invoke the next handler in the chain.

Overrides:

login in class AuthenticationHandler

Parameters:

ctxt - the AuthenticationContext used for this login

Throws:

java.io.IOException

checkAuthenticationFromAuthKey

public static final Member checkAuthenticationFromAuthKey(javax.servlet.http.HttpServletRequest request)
