How to get all users From Owners Group in SharePoint 2013 for a subsite

Question

I am trying to get all the Users from a SharePoint Owner's Group for a subsite. Below Script is Working fine . But it displays both Site and Subsite Users of Owner's Group.

For example If SITE A has SITEOWNERS GROUP and it has SUBSITE A1 . Now when i use this Script in sub site, It should Display the users from SUBSITEOWNERS GROUP. Howeever it Displays users from Both SITEOWNERS GROUP & SUBSITEOWNERS GROUP. Can any one Help me on this to correct my Code.

Answer 1

You are getting site collection groups earlier you are retrieving groups from the site collection, but when you execute your GetData() function, you are passing in a group name, but executing it at the root level.

http://site/_api/web/sitegroups/getbyname('Owners')/users

instead of

http://site/subsite/_api/web/sitegroups/getbyname('Owners')/users
