core_group_get_course_user_groups

Note: Version number is bumped because a new web service is added into the Mobile app service and also in a component.

1. Create a course with a teacher and a couple of students and two groups.
2. Enroll one student in two groups and the other one just in one group
3. Enable "Mobile services": Plugins ► Web Services ► External services
4. Create a Token for the teacher and the student enrolled in two groups:
   • Click on Site administration ► Plugins ► Web services ► Manage tokens
5. Next, you can do a couple of CURL REST call simulating a WS client with the teacher and the student user .
   • First call as a teacher replace the token with the teacher one, replace the courseid value and userid should be the user enrolled in two groups
   • Second call as a student (for retrieving your own groups), replace the token with the student one, and userid should be the student userid
   • You also need to replace the wstoken and the URL of your moodle instance

     curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' -H 'Pragma: no-cache' -H 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' -H 'Accept: application/json, text/javascript, */*; q=0.01' -H 'Cache-Control: no-cache' -H 'Connection: keep-alive' --data 'courseid=3&userid=4&wsfunction=core_group_get_course_user_groups&wstoken=8fb46895ca29a0f0bdac2395e562fe1d' --compressed

6. Confirm that (you should use jsonlint.com for formatting the output):
   • As a teacher you can see all the student groups
   • As a student, you can see only your own groups
7. Do additional requests for testing permissions. Like as a student requesting the other user groups (you should get permission exceptions) or the teacher requesting groups for a student in a different course
