Custom Logout event

Camunda 7 Topics Discussion & Questions

Hi to all,

I would like to customize the logout function for the task list.
After logout, I’d like to go to the SSO page.

I need to change redirect URL to URL my SSO.

For the moment, I’m using a custom camunda-webapp package.

To solve the problem, I tried to use the custom script (https://docs.camunda.org/manual/7.8/webapps/tasklist/configuration/#custom-cripts)
but failed.

I ask for help in solving this task.

Thanks,
Petr

I managed to connect a custom script.
When i use the custom button, the script runs successfully.
But unfortunately it is not called when logout when I use the default button (from component camunda-commons-ui)

'use strict';
define('custom-ng-module', [
    'angular'
], function (angular) {
    var customModule = angular.module('my.custom.module', []);

    customModule.controller('camHeaderViewsCtrl', ['scope', function ($scope) {
        $rootScope.logout = function (){
            console.log('Test');
        };
    }]);

    return customModule;
});

Could you help me to override the default script for my custom script?

Hi @petrovtsev, you can achieve that by doing the following:

  customModule.controller('camHeaderViewsCtrl', ['$window', '$scope', function($window, $scope) {
    // isLoggedIn: flag set to true initially, since user is logged in
    var isLoggedIn = true;
    
    // register listener to 'authentication.changed' event
    var listener = $scope.$root.$on('authentication.changed', function(ev, auth) {
      if(!auth && isLoggedIn) {
        console.log('logout');
        isLoggedIn = false;
      }
    });

    // remove listener to 'authentication.changed' event
    $scope.$on('$destroy', function() {
      listener();
    });

  }]);

  return customModule;
});

Does this help you? Please let me know if you have any questions regarding this.

Hi @siffogh,

is that script supposed to run without any custom buttons (i.e. using the default logout button in the web app)? I tried adding it and registering it as in the doc and it doesn’t seem to be called at all

Thanks,
Luca

Hi there,
I’ve got the same problem. Is there anyone with a solution? I know nothing about Angular… It feel that it can’t be that hard to change such a simple behaviour. But I just don’t know how…

Got it. A bit hacky but it works.

'use strict';
define('custom-logout', ['angular'], function (angular) {
    var customLogoutModule = angular.module('custom-logout', []).run(
        ['$rootScope', function ($rootScope) {

            $rootScope.$on('$viewContentLoaded', function (event) {
                // Get the HTML element of the header widget.
                var div = document.querySelector("[cam-widget-header]");

                // Get the only property on it, its key is jQuery<many numbers> and its value
                // contains the controller ($camWidgetHeaderController) and the isolated
                // Scope ($isolateScope). The logout function is defined in this scope.
                var jQueryKey = Object.getOwnPropertyNames(div)[0];
                var $isolateScope = div[jQueryKey]['$isolateScope'];
                $isolateScope.logout = function () {
                    // Do whatever you want to do on logout.
                    window.location.href = "/logout"
                }

            })
        }]);
});
