5 Credentials

Users can generate a user-access token which is a temporary username and password to logon via RESTAPI or XNAT Upload Assistant

The Chapter 4 mentioned a way to use JSESSION ID to logon to XNAT. But if we are to use software such as XNAT Upload Assistant, we might still need to put in the username and password. Below outlines how we can get a temporary username and password from XNAT. 

1 use command line to get the XNAT temporary username and password

mbp:$ curl -u username "https://test.xnat.sydney.edu.au/data/services/tokens/issue"

Enter host password for user 'username':

{"secret":"gPlzgvaPip6oDGAlJXLypLHBKW3HVbriBSCIZVJcZPic90KDrFkaeMdfefsasef","estimatedExpirationTime":1526514625443,"alias":"451a00c9-441d-4674-84b3-baafb5ab1122","xdatUserId":"username","singleUse":false,"id":3,"disabled":0,"created":1526341825056,"enabled":true,"timestamp":1526341825056}

"alias" follows the temporary username

"secret" follows the temporary password

mbp:$ curl -u 451a00c9-441d-4674-84b3-baafb5ab1122  "https://test.xnat.sydney.edu.au/data/archive/projects"

Enter host password for user 451a00c9-441d-4674-84b3-baafb5ab1122:

{"ResultSet":{"Result":[{"pi_firstname":"","secondary_ID":"ForeFront","pi_lastname":"","name":"ForeFront Ageing and Neurodegeneration","description":"","ID":"FF","URI":"/data/projects/FF"}], "totalRecords": "1"}}


2 use Web Browser to get the XNAT temporary username and password

Logon to https://URL/data/services/tokens/issue

alias: is the temporary username. (temporary username will be reset for every 6 hours)

secret: is the password

mbp:$ curl -u 451a00c9-441d-4674-84b3-baafb5ab1122  "https://URL/data/archive/projects"

Enter host password for user 451a00c9-441d-4674-84b3-baafb5ab1122:

{"ResultSet":{"Result":[{"pi_firstname":"","secondary_ID":"ForeFront","pi_lastname":"","name":"ForeFront Ageing and Neurodegeneration","description":"","ID":"FF","URI":"/data/projects/FF"}], "totalRecords": "1"}}
