I have written a scraper that fetches images from my clients feed. I have noticed that if the url is not absolute, I get 400 error (Bad Request) from the client. Does anyone know how to convert relative url to absolute url in Java?

This is my input url https://www.sevilleclassics.com/../uploads/products/Bin-Rack.jpg and my output url (absolute one) should look like https://www.sevilleclassics.com/uploads/products/Bin-Rack.jpg (difference is /../uploads vs /uploads)

`URI.normalize` is your friend – Jochen Bedersdorfer Nov 03 '17 at 17:24
@JochenBedersdorfer That won't remove the first `../` in this example. – Michael Nov 03 '17 at 17:30

Refer this https://stackoverflow.com/questions/3665484/how-to-get-url-using-relative-path – arjunsv3691 Nov 03 '17 at 17:31
it won't because there's nowhere to go, i.e. the URI is not valid for the server (there are no more path segments that .. could be reduced for). You need to get the correct base URL first. – Jochen Bedersdorfer Nov 03 '17 at 17:34
btw, if you are scraping, there's a little known `` tag that determines how relative URLs are resolved. – Jochen Bedersdorfer Nov 03 '17 at 17:35
You need to solve it when you scrape see https://stackoverflow.com/questions/4144529/how-to-extract-absolute-url-from-relative-html-links-using-jsoup and https://stackoverflow.com/questions/12041676/how-to-resolve-relative-url-with-jsoup – Oleg Nov 03 '17 at 18:03
