How to login to spring secured API ?

The developers have created the application with spring security and i need to login to that application.

These are the request mapping the application uses for further request :

@RestController
@RequestMapping("/service/billing")

Following is my code :

@Before
	public void init(){
		RestAssured.baseURI = "https://example.com";
		RestAssured.port = 8080;
		RestAssured.basePath = "/portal";
	}

@Test
	public void userAuthentication(){
given().
		auth().form(userName, password, FormAuthConfig.springSecurity().
				withLoggingEnabled(new LogConfig(captor,true))).
		expect().
		statusCode(200).body(equalTo("OK")).
		when().
		get("/service/billing");
	}

In response, i get the HTML Page as Login Page, means the application not logged in successfully with assertion error. I tried with each and everything to get out of this. Used fromAuthconfig as mentioned above, but didn’t get though.

Can anybody help me on this? I am newbie to this rest assured api.

Hello guys,

There is no news regarding this issue?

I’m also having difficulties to fill the login form for this website -> https://www.themoviedb.org/login.

This is my code:

 public String  login() {
        StringBuilder cookiesBuilder = new StringBuilder();
        RestAssured.given().log().all()

                        .auth().form("<username>", "<password>", new FormAuthConfig("/login", "username", "password").withLoggingEnabled())
                        .filter(new ResponseLoggingFilter())
                        .filter(new RequestLoggingFilter())
                        .baseUri("https://www.themoviedb.org")
                        .relaxedHTTPSValidation()
                        .when()
                        .post("/login")
                        .then()
                        .assertThat().log().all()

        .extract().cookies().forEach((s, s2) -> {
            cookiesBuilder.append(s)
                    .append("=")
                    .append(s2)
                    .append("; ");
        });
        return cookiesBuilder.toString().trim();

Also, I tried this one :

public String  login() {
        StringBuilder cookiesBuilder = new StringBuilder();
        RestAssured.given().log().all()
               .contentType(ContentType.URLENC)
               .queryParam("username", "<username>")
               .queryParam("password", "<password>")
               .header("Content-Type", "application/x-www-form-urlencoded")
                .post("https://www.themoviedb.org.login)

        .extract().cookies().forEach((s, s2) -> {
            cookiesBuilder.append(s)
                    .append("=")
                    .append(s2)
                    .append("; ");
        });
        return cookiesBuilder.toString().trim();

After numerous attempts applied these calls and worked:

RestAssured.given() // other set up methods
    .contentType(ContentType.URLENC)
    .formParam("username", "admin")
    .formParam("password", "admin")
    .post("/login")
    .then()
    .statusCode(FOUND.value());

Next steps I’ve checked location header and it was the one I expected
