Remove json key from response in jmeter and feed processed response as request to next sampler

Question

I have a sampler 1 which generates response like

{ ....... updatedAt: dateAndtime, createdAt: datetime}

Now this response i have to process by removing updatedAt , createdAt key, values and then feed same as request body to next sampler. Could any one help , how to do this?

Answer 1

1. Add JSR223 PostProcessor as a child of the request which returns the above JSON

2. Put the following code into "Script" area:

   def response = new groovy.json.JsonSlurper().parse(prev.getResponseData())
   
   response.remove('updatedAt')
   response.remove('createdAt')
   
   vars.put('request', new groovy.json.JsonBuilder(response).toPrettyString())
   

3. Refer the amended request value as ${request} later on where required
