How to validate the nested api objects in Playwright spi testing

Question

I want to validate the nested api objects. I want to check if the value of 'id' inside the 'data' object is "1"

{
  page: 1,
  per_page: 6,
  total: 12,
  total_pages: 2,
  data: [
    {
      id: 1,
      email: '[email protected]',
      first_name: 'George',
      last_name: 'Bluth',
      avatar: 'https://reqres.in/img/faces/1-image.jpg'
    }
  ]
}

How can I achieve this?

First you need to convert your json to a valid one.
And after in java you can do something like this.

public class Validation {
    public static void main(String[] args) throws IOException {
      String jsonAnswer = "{'page': 1,'per_page': 6,'total': 12,'total_pages': 2,'data':" +
              " [{'id': 1,'email': '[email protected]','first_name': 'George','last_name':" +
              " 'Bluth','avatar': 'https://reqres.in/img/faces/1-image.jpg'}]}";
        JsonObject json = JsonParser.parseString(jsonAnswer).getAsJsonObject();
        int id = json.get("data")
                .getAsJsonArray().get(0)
                .getAsJsonObject().get("id").getAsInt();
        if(1 == id){
            System.out.println("Validation passed!");
        }else{
            System.out.println("Validation failed!");
        }
    }
}
