How to save json response from API call into json files?

Question

Running through lots of files and response is also in thousands. How do I save the json response with names similar to the name of files I sent as request? Is there any way? For example if I read a file with name"arnold.json" I want to take the response and write it to a file with name: "arnold_response.json"(something like this) The response I am getting looks like this:

{
  "resourceType": "Bundle",
  "id": "235-253-235-235-235",
  "type": "transaction-response",
  "link": [
    {
      "relation": "self",
      "url": "https://someurl.com"
    }
  ],
  "entry": [
   {
      "response": {
        "status": "201 Created",
        "location": "Player/aerear",
        "etag": "1",
        "lastModified": "2020"
      }
    }
  ]
}

Answer 1

You can add a JSR223 Listener and use the following code there:

new File(vars.get('file')).bytes = prev.getResponseData()

where:

• vars stands for JMeterVariables
• prev stands for the previous SampleResult
