How to extract a complex value in JsonPathExtractor-CodePudding

I have below Json expression in Json Path Extractor in JMeter

$.data[0].materials[?(@.id)].reports[*].metadata['materialName','materialType']

The above expression returned as below for every 'id' in a json array

materialName1, materialType1

materialName2, materialType2

but I want to extract the value of 'id' along with 'materialName' and 'materialType' as mentioned below

id1, materialName1, materialType1

id1, materialName2, materialType2

id2, materialName3, materialType3

id2, materialName4, materialType4

etc.

please help me on this.

Thanks, Jatin

CodePudding user response：

Add JSR223 sampler and log it directly with:

log.info(variable)

Variables can be resolved in any sampler comment section with ${variable} for testing purposes.

CodePudding user response：

JMeter provides __logn() function allowing printing whatever you want to jmeter.log file

Also in case of > 1 matches returned by JSON Extractor JMeter generates the following variables

var_1=foo
var_2=bar
...
var_matchNr=2

so you will be able to print them to jmeter.log file as:

1.upto(vars.get('var_matchNr') as int, { index ->
    log.info(vars.get('var_'   index))
})

if you want to print to STDOUT instead - replace log.info with println
