Java - HttpURLConnection getPermission() Method

The Java HttpURLConnection getPermission() method returns a SocketPermission object representing the permission necessary to connect to the destination host and port. It overrides getPermission() method of URLConnection class.

Following is the declaration for java.net.HttpURLConnection.getPermission() method

public Permission getPermission() throws IOException

Parameters

NA

Return Value

a SocketPermission object representing the permission necessary to connect to the destination host and port.

Exception

IOException − if an error occurs while computing the permission.

Example 1

The following example shows the usage of Java HttpURLConnection getPermission() method for a valid url with https protocol. In this example, we're creating an instance of URL class. Using url.openConnection() method, we're getting the HttpURLConnection instance. Using getPermission(), we're getting the value of an Permossion object and printing the same −

package com.tutorialspoint;

import java.io.IOException;
import java.net.URL;
import java.net.HttpURLConnection;
import java.security.Permission;

public class HttpURLConnectionDemo {
   public static void main(String [] args) {
      try {
         URL url = new URL("https://www.tutorialspoint.com");
         HttpURLConnection httpURLConnection = (HttpURLConnection)url.openConnection();
         Permission permission = httpURLConnection.getPermission();
         System.out.println("Permission: " + permission);
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

Let us compile and run the above program, this will produce the following result −

Output

Permission: ("java.net.SocketPermission" "www.tutorialspoint.com:80" "connect,resolve")
