Services 3: How to retrieve the current logged in user ID I can get a list of all users by going to //endpoint/user/ but how do I return the current user?

My primary goal is to find out if the user is authenticated.
To do this you can use the system resource "connect".  Enable that resource:


to go admin/structure/services/list/serp/resources
expand "system"
check "connect" Hit save


Then, you post (posting nothing) to /system/connect and it returns the current user info and session id.
