ID Generator

Overview

By default Janssen Auth Server uses an internal method to generate unique identifiers for new person/client, etc. entries. In most cases the format of the ID is:

'!' + idType.getInum() + '!' + four_random_HEX_characters + '.' + four_random_HEX_characters.

The ID generation script enables an admin to implement custom ID generation rules.

Interface

The ID Generator script implements the IdGeneratorType interface. This extends methods from the base script type in addition to adding new methods:

Inherited Methods

Method header	Method description
def init(self, customScript, configurationAttributes)	This method is only called once during the script initialization. It can be used for global script initialization, initiate objects etc
def destroy(self, configurationAttributes)	This method is called once to destroy events. It can be used to free resource and objects created in the init() method
def getApiVersion(self, configurationAttributes, customScript)	The getApiVersion method allows API changes in order to do transparent migration from an old script to a new API. Only include the customScript variable if the value for getApiVersion is greater than 10

New Methods

Method header	Method description
def generateId(self, appId, idType, idPrefix, configurationAttributes)	appId is application ID, idType is ID Type, idPrefix is ID Prefix

Objects

Object name	Object description
customScript	The custom script object. Reference
configurationAttributes	configurationProperties passed in when adding custom script. Map<String, SimpleCustomProperty> configurationAttributes

Use case: Sample ID generator

This script has been adapted from the Gluu Server sample ID generator script.

Script Type: Python

from io.jans.model.custom.script.type.id import IdGeneratorType

import java

class IdGenerator(IdGeneratorType):
    def __init__(self, currentTimeMillis):
        self.currentTimeMillis = currentTimeMillis

    def init(self, configurationAttributes):
        print "Id generator. Initialization"
        print "Id generator. Initialized successfully"

        return True   

    def destroy(self, configurationAttributes):
        print "Id generator. Destroy"
        print "Id generator. Destroyed successfully"
        return True   

    def getApiVersion(self):
        return 1

    # Id generator init method
    # appId is application Id
    # idType is Id Type
    # idPrefix is Id Prefix
    def generateId(self, appId, idType, idPrefix, configurationAttributes):
        print "Id generator. Generate Id"
        print "Id generator. Generate Id. AppId: '", appId, "', IdType: '", idType, "', IdPrefix: '", idPrefix, "'"

        # Return None or empty string to trigger default Id generation method
        return None

Script Type: Java

import java.util.Map;

import io.jans.model.SimpleCustomProperty;
import io.jans.model.custom.script.model.CustomScript;
import io.jans.model.custom.script.type.id.IdGeneratorType;
import io.jans.service.custom.script.CustomScriptManager;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class EndSession implements EndSessionType {

    private static final Logger log = LoggerFactory.getLogger(CustomScriptManager.class);

    @Override
    public boolean init(Map<String, SimpleCustomProperty> configurationAttributes) {
        log.info("ID Generator. Initializing...");
        log.info("ID Generator. Initialized");
        return true;
    }

    @Override
    public boolean init(CustomScript customScript, Map<String, SimpleCustomProperty> configurationAttributes) {
        log.info("ID Generator. Initializing...");
        log.info("ID Generator. Initialized");
        return true;
    }

    @Override
    public boolean destroy(Map<String, SimpleCustomProperty> configurationAttributes) {
        log.info("ID Generator. Destroying...");
        log.info("ID Generator. Destroyed.");
        return true;
    }

    @Override
    public int getApiVersion() {
        return 11;
    }

    @Override
    public String generateId(String appId, String idType, String idPrefix, Map<String SimpleCustomProperty> configurationAttributes) {
        log.info("ID Generator. Generate Id");
        // Return None or empty string to trigger default Id generation method
        return "";
    }
}
