What is the error in getting the token?

Question

Java

I tried to get a token and just withdraw it, but for some reason it does not work. What could be wrong?

public class Token {
    private final String response_type;
    private String access_token;
    private final String client_id;

    public Token() {
        this.response_type = "token";
        this.client_id = "a42b1aed99284cb3a62f4d57f2392385";
    }
public void setConnection() throws IOException, URISyntaxException {
        //код получения token'a
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost post = new HttpPost("https://oauth.yandex.ru/authorize?" +
    "response_type="+response_type+
    "&client_id="+client_id);
    HttpResponse response;
    response = httpClient.execute(post);
    post.abort();
    String HeaderLocation = response.getFirstHeader("location").getValue();
    URI RedirectUri = new URI(HeaderLocation);
    HeaderLocation = response.getFirstHeader("location").getValue();
    // Проходим по нему
    post = new HttpPost(HeaderLocation);
    response = httpClient.execute(post);
    post.abort();
    HeaderLocation = response.getFirstHeader("location").getValue();
    access_token = HeaderLocation.split("#")[1].split("&")[0].split("=")[1];
    System.out.println(access_token);
    }
    public static void main(String[] args) throws IOException, URISyntaxException, AWTException, InterruptedException, NoSuchAlgorithmException {
    Token yandexAPI = new Token();
    yandexAPI.setConnection();
    
    }
}

Answer 1

httpClient.execute(post);
post.abortion();

There is something I don't understand about this...
