解析浏览器信息_nl.basjes.parse.useragent-优快云博客

本文介绍了一个Java程序，该程序使用UASparser库来解析User-Agent字符串，并获取URL的相关信息。通过这个示例，我们可以了解到如何识别客户端的操作系统、浏览器等详细信息。

import java.io.IOException;
import java.net.MalformedURLException;
import java.util.List;

import cz.mallat.uasparser.OnlineUpdater;
import cz.mallat.uasparser.UASparser;
import cz.mallat.uasparser.UserAgentInfo;
import nl.basjes.parse.useragent.UserAgentAnalyzer;

public class UserAgent  {
     static UASparser uasParser = null;  

        static {  
            try {  
                uasParser = new UASparser(OnlineUpdater.getVendoredInputStream());  
            } catch (IOException e) {  
                e.printStackTrace();  
            }  
        }  

        public static void main(String[] args) throws MalformedURLException {  
            java.net.URL  url = new  java.net.URL("https://www.baidu.com/s?wd=java%E5%8F%AA%E8%8E%B7%E5%8F%96url&rsv_spt=1&rsv_iqid=0xa0093f7f00027442&issp=1&f=8&rsv_bp=1&rsv_idx=2&ie=utf-8&rqlang=cn&tn=baiduhome_pg&rsv_enter=1&rsv_t=563bRpAGQB0h5NQMpURJOzLGknk4lukbsP0z0TR1yydr9OFtVYkKAd0V5L7ddDteAjO6&oq=%25E5%258F%25AA%25E8%258E%25B7%25E5%258F%2596url&inputT=2390&rsv_pq=efa6878c0001696b&rsv_sug3=77&rsv_sug1=51&rsv_sug7=100&rsv_sug2=0&rsv_sug4=2393&rsv_sug=1");

            String host = url.getHost();// 获取主机名 

            System.out.println("host:"+host);// 结果 blog.youkuaiyun.com
