Extract multiple values with JSON extractor

I'm getting following data in response of a request:

{
  "items": [
    {
      "id": 54925,
      "currCode": "USD",
      "lastUpdated": 1531233169000
    },
    {
      "id": 54926,
      "currCode": "USD",
      "lastUpdated": 1531233169000
    },
    {
      "id": 54927,
      "currCode": "USD",
      "lastUpdated": 1531233169000
    }
  ],
  "totalCount": 3
}

As we can see there are three different ids in the data(54925,54926,54927) I want to perform iterate over all these ids and perform some operation( basically I want to use like foreach(String id: ids) { request(id);}

I added a JSON extractor as follows:

enter image description here As per my research(research link) it's supposed to store all the ids in the id_list

After this added a foreach loop to iterate over these values:

But somehow the it's not going inside this for loop. What I'm doing wrong here? is there any other way to fetch all these ids and loop through them?

Solution

  • You forgot to mention in JSON Extractor you expect it to return all values by setting Match No. as -1

    -1 means extract all results, they will be named as _N
