Class AuthKeyAuthenticationHandler

  • All Implemented Interfaces:
    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().

      • 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
