比如我要解析下面這個url：

myscheme://admin@blog.nihao001.com:8080/index.jsp?username=asdf&password=123456&msg=%e4%bd%a0%e5%a5%bd#editor

只要使用URI這個類就可以解析了。

上代碼：

import java.net.URI;

import java.net.URISyntaxException;

public class Main {

public static void main(String[] args) {

String SCHEMA ="myscheme://admin@blog.nihao001.com:8080/index.jsp?username=asdf&password=123456&msg=%e4%bd%a0%e5%a5%bd#editor";

try {

URI uri = new URI(SCHEMA);

System.out.println("getScheme:" + uri.getScheme());

System.out.println("getHost:" + uri.getHost());

System.out.println("getPort:" + uri.getPort());

System.out.println("getAuthority:" + uri.getAuthority());

System.out.println("getPath:" + uri.getPath());

System.out.println("getRawQuery:" + uri.getRawQuery());

System.out.println("getQuery:" + uri.getQuery());

System.out.println("getFragment:" + uri.getFragment());

System.out.println("getRawUserInfo:" + uri.getRawUserInfo());

System.out.println("getUserInfo:" + uri.getUserInfo());

} catch (URISyntaxException e) {

e.printStackTrace();

}

}

}

看結果：

getScheme:myscheme

getHost:blog.nihao001.com

getPort:8080

getAuthority:admin@blog.nihao001.com:8080

getPath:/index.jsp

getRawQueryusername=asdf&password=123456&msg=%e4%bd%a0%e5%a5%bd

getQuery:username=asdf&password=123456&msg=你好

getFragment:editor

getRawUserInfo:admin

getUserInfo:admin
