How to get multiple values at once from JSON file.?

[#1]

Hi , i have a JSON file like below. currently i am using EvaluateJSONPath to get the filename and unique-id and updateattribute to concatenate those 2 into one filename using ${filename:append('_'):append(${unique-id})}

can i do that in EvaluateJSONPath only.? basically i want to avoid 2nd processor if it can be done.

Try the following as your JSONPath expression in EvaluateJSONPath:

concat($.name,"_",$.unique-id)

Expression Language is not supported in the JSONPath expressions, so if you need to use flow file attributes you'll need the additional processor to join the two attributes together as you described.

is this what you are referring to.? this is giving filename2 as empty string.

Jeez I would hope not, I'm not aware of any platform differences for Jayway (the underlying library used to do JSONPath stuff in NiFi)
