Create A New User Session
This call allows for manual management of HTTP sessions within XNAT. This is particularly useful when you want to re-use the same session across multiple curl or XNATDataClient calls.
POST - /data/JSESSION
Parameters: Enter user credentials via calling mechanism, i.e:
$ curl -u username:password -X POST https://yourxnatdomain/data/JSESSION
Response: A new JSESSION ID string, for example:
You can then use this JSESSION ID in a cookie in lieu of user credentials to authenticate subsequent calls, e.g.:
curl --cookie JSESSIONID=3940FAAC4CB8DD368A9A1575372ECBBA -X GET http://10.1.1.17/xnat/data/projects
The JSESSION ID can expire, or can be manually forced to expire by site administrators. Session expiration will invalidate any future operations attempting to use this cookie.
Get ID Of Current User Session
Returns the JSESSION ID for the currently logged in user.
GET - /data/JSESSION
Response: A JSESSION ID string
Invalidate The Current User Session
This is a way of manually logging off and preventing your cookie from being used once you have completed your operation. If you run this in the browser, all your current login sessions will immediately expire.
DELETE - /data/JSESSION/
