CAS Interrupt

[Matthew Gordon]

Built CAS 6.5.3 with:

support-interrupt-webflow

Added this line to the config:

cas.interrupt.groovy.location=/etc/cas/scripts/INTERRUPT.groovy

It does not appear to be calling the groovy script at all. I even added an intentional coding error expecting to break CAS, and nothing. Any ideas?

LOG:

2022-05-14 19:53:37,426 DEBUG [org.apereo.cas.interrupt.webflow.actions.InquireInterruptAction] - <Invoking interrupt inquirer using [GroovyScriptInterruptInquirer]>

2022-05-14 19:53:37,429 DEBUG [org.apereo.cas.interrupt.webflow.actions.InquireInterruptAction] - <Webflow interrupt is skipped since no inquirer produced a response>

SCRIPT:

import org.apereo.cas.interrupt.InterruptResponse

def run(final Object... args) {
    def principal = args[0]
    def attributes = args[1]
    def service = args[2]
    def registeredService = args[3]
    def requestContext = args[4]
    def logger = args[5]

    logger.info("**principal - Attributes:")
    principal.properties.each {  logger.info("KEY: $it.key -> VALUE: $it.value") }

    logger.info("**attributes - Attributes:")
    attributes.properties.each {  logger.info("KEY: $it.key -> VALUE: $it.value") }

    logger.info("**service - Attributes:")
    service.properties.each {  logger.info("KEY: $it.key -> VALUE: $it.value") }

    logger.info("**registeredService - Attributes:")
    registeredService.properties.each {  logger.info("KEY: $it.key -> VALUE: $it.value") }

    logger.info("**requestContext - Attributes:")
    requestContext.properties.each {  logger.info("KEY: $it.key -> VALUE: $it.value") }

    def block = false
    def ssoEnabled = false

    return new InterruptResponse("Message", [link1:"google.com", link2:"yahoo.com"], block, ssoEnabled)
   
    /*return new InterruptResponse(message: message, redirectTo: redirectTo, block: block, ssoEnabled: ssoEnabled, autoRedirect: true, autoRedirectAfterSeconds: 1)*/
}

Can you use println instead of logger ? like this :

println "==========================="

println principal

println service

println "==========================="

Hello Mathieu,

Thank you for your reply!

It's not even getting that far. It's like it's not attempting to process the groovy script for the interrupt. I did attempt to add those lines, in several places, and did not see any output in the tomcat or CAS logs.

2022-05-18 16:41:51,370 DEBUG [org.apereo.cas.interrupt.webflow.actions.InquireInterruptAction] - <Invoking interrupt inquirer using [GroovyScriptInterruptInquirer]>
2022-05-18 16:41:51,373 DEBUG [org.apereo.cas.interrupt.webflow.actions.InquireInterruptAction] - <Webflow interrupt is skipped since no inquirer produced a response>

I am using the example code here: https://apereo.github.io/cas/6.5.x/webflow/Webflow-Customization-Interrupt-Groovy.html

Thank you,

Matt

We're seeing the same thing on our end moving from 6.4.x to 6.6.x

2023-02-16 18:52:47,362 DEBUG [org.apereo.cas.interrupt.webflow.actions.InquireInterruptAction] - <Invoking interrupt inquirer using [GroovyScriptInterruptInquirer]>

2023-02-16 18:52:47,362 DEBUG [org.apereo.cas.interrupt.webflow.actions.InquireInterruptAction] - <Webflow interrupt is skipped since no inquirer produced a response>

Is anyone else experiencing this issue and have a fix?

Works fine for us on 6.6.4, using something below

    message = "Test message";
    redirect_to = [link1: ""];
    block = false;
    sso_enabled = true;
    interrupt_flow = false;
   
    if (interrupt_enabled) {
        if (registeredService) {
            svc_id = 0;
            if (registeredService.containsKey('id')) {
                svc_id = registeredService.id.intValue();
            }
            svc_list = [106, 108];
            url1 = "https://url......";
            url2 =  "https://url......";
            url3 =  "https://url......";
           
            if (authentication.principal.attributes.containsKey('eduPersonAffiliation')) {
                edu_affiliation = principal.attributes.eduPersonAffiliation.join(", ");
                profile_list = ["faculty", "staff", "student"];
                if (profile_list.contains(edu_affiliation)) {
                    if (svc_list.contains(svc_id)) {
                        interrupt_flow = true;
                        if (svc_id == 106) {
                            redirect_to = [link1: url1];
                        }
                        if (svc_id == 108) {
                            redirect_to = [link1: url2];
                        }
                    }
                }
            }
        }
    }
    return new InterruptResponse(message: message, links: redirect_to, block: block, ssoEnabled: sso_enabled, interrupt: interrupt_flow, autoRedirect: true)

Thanks for the reply John.

Are you using "def run(final Object... args) { }" as your function definition?

Like the original poster, I have reverted back to using the out of the box example in the documentation for interrupts, however it's just not finding it according to the DEBUG logs.

[John]

Yes, full groovy below, and all we have set in config,

cas.interrupt.core.trigger-mode=AFTER_SSO
cas.interrupt.groovy.location=file:/etc/cas/scripts/interrupt.groovy

import org.apereo.cas.interrupt.InterruptResponse

def run(final Object... args) {
    def principal = args[0]
    def attributes = args[1]
    def service = args[2]
    def registeredService = args[3]
    def requestContext = args[4]
    def logger = args[5]
