How to get the absolute URL from the relative URL using Jsoup?

Many of the websites load various resources like images and CSS using relative URLs. If you want to download these resources as well using Jsoup, you need to convert these relative URLs to the absolute URLs.

Jsoup element class provides absUrl method which converts relative URLs to absolute URLs using base URI.

1	public String absURL(String attributeName)

If the URL is already an absolute URL, it is returned as-is. If it is a relative URL, it is converted to an absolute URL using the base URI and returned.

Example

package com.javacodeexamples.libraries.jsoup;

import java.io.IOException;

import org.jsoup.Jsoup;

import org.jsoup.nodes.Document;

import org.jsoup.nodes.Element;

import org.jsoup.select.Elements;

public class JsoupGetAbsoluteURLExample {

public static void main(String[] args) {

try{

Document document =

Jsoup

.connect("http://www.google.com")

.userAgent("Mozilla/5.0")

.timeout(10 * 1000)

.get();

Elements elements = document.select("img[src]");

for(Element e : elements){

System.out.println("Relative URL: " + e.attr("src"));

System.out.println("Absolute URL: " + e.absUrl("src"));

}

}catch(IOException ioe){

System.out.println("Exception: " + ioe);

}

Output

1 2	Relative URL: /images/icons/product/chrome-48.png Absolute URL: http://www.google.co.in/images/icons/product/chrome-48.png

You can also use the attr method with the “abs:” prefix with attribute name to get the absolute URL instead of the absUrl method as given below.

1	System.out.println("Absolute URL: " + e.attr("abs:src"));

As a standard practice you should always use the HTTP user agent and referer values while making the Jsoup request.
