Getvar using JSON

Getvar using JSON

To do a
getvar
 in SGD you use the format:
! U1 getvar "sgd.name" 
! U1 getvar "ip.port" 
! U1 getvar "device.location"
To get a variable value using JSON:
{}{"sgd.name":null} 
returns
 {"sgd.name":"value"} 
{}{"ip.port":null} 
returns
 {"ip.port":"9100"} 
{}{"device.location":null} 
returns
 {"device.location":"my desk"}
You can get several values as follows:
{}{"device.friendly_name":null,  "device.company_name":null,  "device.company_contact":null, "device.location":null}
The response is:
{"device.friendly_name":"XXQLJ120900310", 
"device.company_name":"Zebra Technologies", 
"device.company_contact":"123-555-1212", 
"device.location":"My Desk"}
