Question

In Rest Assured Framework POST response is not showing ID created and Time that I am getting through POSTMAN.

@Test
public void newuser() {

    service = new services();

    // response = service.addProduct("444", "OIL","Natural Tea Tree", "210.0");

    response = service.AddUser("Gagan", "leeee");

    if (response.statusCode() == 201) {

        Gson gson = new Gson();

        System.out.println(response.asString());

    PostUser[] userlist = gson.fromJson(response.asString(), PostUser[].class);

    System.out.println(userlist[0].getCreatedAt());


        System.out.println(response.statusCode());

    }
}

}

Eclipse Console Output-----

[{"name":"Gagan","job":"leeee"}]
null
201

Postman Output

    "name": "Gagan",
    "job": "leee",
    "id": "327",
