如何获取uri的最后一个路径段 [英] How to obtain the last path segment of an uri

问题描述

我输入的字符串是 URI 。怎么可能得到最后一个路径段？
，在我的情况下是一个id？

I have in input a string that is an URI. how is possible to get the last path segment? that in my case is an id?

这是我的输入网址

String uri = "http://base_path/some_segment/id"

我必须获得我尝试过的ID

And I have to obtain the id I have tried with this

String strId = "http://base_path/some_segment/id";
strId=strId.replace(path);
strId=strId.replaceAll("/", "");
Integer id =  new Integer(strId);
return id.intValue();

但它不起作用，肯定有更好的方法。

but it doesn't work and for sure there is a better way to do it.

推荐答案

是您要找的：

URI uri = new URI("http://example.com/foo/bar/42?param=true");
String path = uri.getPath();
String idStr = path.substring(path.lastIndexOf('/') + 1);
int id = Integer.parseInt(idStr);

或者

URI uri = new URI("http://example.com/foo/bar/42?param=true");
String[] segments = uri.getPath().split("/");
String idStr = segments[segments.length-1];
int id = Integer.parseInt(idStr);
