Jmeter - How to remove id from given json - json

Question

I'm comparing 2 jsons with JSR223 Assertion and I'm willing to remove the ids from all levels from the response json:
{
"id" : 52906,
"name1" : "559812 Company name1",
"name2" : "559812 Company name2",
"country" : "DE",
"interests" : {
"id" : 848675,
"description" : false
},
"emails" : [ {
"id" : 904881,
"address" : "559812#gmail.com"
} ],
...
I'm using the following Groovy code:
def slurper2 = new JsonSlurper();
def jsonResponse = slurper2.parseText(prev.getResponseDataAsString());
jsonResponse.rows.findAll { it.remove("id") };
But it doesn't work - Please advise.

Answer 1

I don't really understand where you got this rows bit as I don't see any JSON Array named "rows" in your response.
If you want to remove all "id" attributes you can use the following approach:
def response = prev.getResponseDataAsString()
def responseWithoutIds = response.replaceAll("\"id\"[ ]*:[^,}\\]]*[,]?", "")
// do what you need with the modified response, i.e. store it into a JMeter Variable
vars.put("responseWithoutIds", responseWithoutIds)

import groovy.json.*;
def s='''{
"id" : 52906,
"name1" : "559812 Company name1",
"name2" : "559812 Company name2",
"country" : "DE",
"interests" : {
"id" : 848675,
"description" : false
},
"emails" : [ {
"id" : 904881,
"address" : "559812#gmail.com"
} ]
}
