Jmeter: Request should be change as per previous response

Question

{
    {"status": 
    {"id":2,}
}

Next service should be

{
    "Data":"ABC"
}

similarly :

set Data = "DEF" if Id = 2 , Data = "GHI" if id = 3

Answer 1

1. Add JSR223 PostProcessor as a child of the request which produces this status JSON

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

   def id = com.jayway.jsonpath.JsonPath.read(prev.getResponseDataAsString(), '$..id').get(0).toString()
   switch (id) {
       case '2':
           vars.put('Data', 'DEF')
           break;
       case '3':
           vars.put('Data', 'GHI')
   }
   

3. Amend your HTTP Request sampler Body Data to look like:

   

4. If id will be 2 - Data value will become DEF, if id will be 3 - Data will become GHI
