How to test Rest API which require authentication using Rest assured

Question

I want to test a Rest API which require authentication, before getting the Json response. FOr exa. If i want to visit rest API: http://192.168.xx.xx:9000/dashboards/all/list/m1/p1/sch1

then

if I am not already logged in , then this will redirect me to Login HTML page, and after login, this will show me the Json output.

Now I want to write a Rest assured code in java for same: I dont know , whether this is possible to do login using this or not.

SO I written a simple code for same::

public class TestNGSimpleTest1 {

    @Test
    public void testAdd() {
            //expect().
            //statusCode(400).
            //body("Status", equalTo("Success")).
            //when().
            //get("http://localhost:9000/dashboards/all/list/m1/p1/sch1");
            //System.out.println("Response received is ::" +res);   
            Response res = get("http://localhost:9000/dashboards/all/list/m1/p1/sch1");
            assertEquals(200,res.getStatusCode());
            String json = res.asString();
            System.out.println("Response received is :: " +json);
    }

So here instead of getting the Json response, I am getting the HTML source page response.

So, my question is if possible, how to do login and get the Json response.

Thanks in advance.

If you are using default authentication from JIRA, then preemptive authentication is what you need. Below are the sample code.

RestAssured.baseURI = System.getProperty("baseurl");
PreemptiveBasicAuthScheme authScheme = new PreemptiveBasicAuthScheme();
authScheme.setUserName("admin");
authScheme.setPassword("admin");
RestAssured.authentication = authScheme;

The sample code will help you do the authentication before every request you send.
