json - Calling Rest API in java from Hackerrank IDE

Question

I was trying to call an api like below. It works in my IDE(Intellij), where as it fails in hackerrank IDE while getting input stream.

import java.io.*;
import java.util.*;
import java.net.*;
    
URL url = new URL("https://jsonmock.hackerrank.com/api/article_users?page=1");  
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("GET");  
connection.addRequestProperty("Content-Type", "application/json"); 
InputStream is = connection.getInputStream();    
       

Getting an error:

error while calling: java.net.UnknownHostException: jsonmock.hackerrank.com  

inside hacker rank IDE.

Please let me know your suggestions

Answer 1

Are you sure Hackerrank IDE has api call feature?

Perhaps for security or some other reason, this feature may be blocked or not supported.
