如何仅对网址的最后一部分进行正则表达式？

Question

I want to do a regex that target the end of a url:

www.company.com/orders/ thanks

If you return from email or account page order ID is populated in the end:

www.company.com/orders/thanks/ 1sfasd523425

So I only want to target the URL that ends with /thanks

This thread bring is similiar: How do I get the last segment of URL using regular expressions

Had something similair .*\\/thanks\\/.+ but target incorrectly.

EDIT: Only target URLs ending with /thanks or /thanks/

Answer 1

Try with lookahead like this.

Regex: .+(?=\\/thanks$).+

Explanation: This will match the URL only if thanks is at end of string by positive lookahead .

Use URL object dont parse it yourself 

URL url = new URL("http://stackoverflow.com/questions/36616915/how-to-regex-last-part-of-url-only");
URLDecoder.decode(url.getPath(), "utf-8");
url.getPath();
url.getContent();
url.getPort();
url.getContent();
