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

问题描述

我输入的是URI字符串.

这是我的输入网址:

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

并且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();

但是它不起作用，并且肯定必须有一种更好的方法来实现它.

but it doesn't work, and surely there must be a better way to do it.

推荐答案

就是您要寻找的东西:

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);
