Code: Select all

function onUserLogin(event) {
    var session = event.getParameter(SFSEventParam.SESSION);
    var username = event.getParameter(SFSEventParam.LOGIN_NAME);
    var password = event.getParameter(SFSEventParam.LOGIN_PASSWORD);
    var zone = getParentZone();
    var privilegeManager = zone.getPrivilegeManager();


    var privilegeProfile = privilegeManager.getPermissionProfile(2); // ID: Moderator

    trace("=== Starting Debugging ===");

I am attempting to assign permissions to a user through an extension using the custom login event, but I keep encountering an error. No matter what I try, it indicates that the type of data I'm sending to set the user's permissions is incorrect. I would appreciate your help, as I am feeling quite frustrated and can't understand what's going wrong.

Hi,
I recommend checking the documentation here:
https://docs2x.smartfoxserver.com/Advan ... ge-manager

As you can see permissions IDs are obtained from the DefaultPermissionProfile class
(see the example at the bottom of the article)

Thanks

Hi Lapo,
Thanks for the reply and the documentation link!
I realized that in a JavaScript extension, accessing `DefaultPermissionProfile` directly doesn't work because it’s not predefined by the system. However, this can be resolved by importing the class using Java integration. Here's how I managed to make it work:

Code: Select all

var DefaultPermissionProfile = Java.type('com.smartfoxserver.v2.security.DefaultPermissionProfile');

Once I imported the class this way, I was able to reference the profiles correctly, and the issue with casting the permission profile was resolved.
Hopefully, this clarification helps others encountering a similar issue when working with JavaScript extensions.
Thanks again for your assistance!
