不得不说第三方包才是快速实现程序的关键

Maven

插件Maven-search

方便简单的利用Maven管理第三方包

参数解析

com.beust.jcommander.Parameter

利用注解＋反射机制还是很简洁的

package org.sec.config;
import com.beust.jcommander.Parameter;
public class Command {
    @Parameter(names = {"-h", "--help"}, description = "Help Info", help = true)
    public boolean help;
    @Parameter(names = {"-u"},description = "Target Url")
    public String url;
    @Parameter(names = {"-k"},description = "Target Key")
    public String targetKey;
}

import com.beust.jcommander.JCommander;
import org.sec.config.Command;
Command command = new Command();
JCommander jc = JCommander.newBuilder().addObject(command).build();
jc.parse(args);
if (command.help) {
    jc.usage();
    return;
}
if (command.url == null || command.url.equals("")) {
    return;
}
String url = command.url;

HTTP请求

com.github.kevinsawicki.http

感觉还是比较方便

package Main;
import com.github.kevinsawicki.http.HttpRequest;
import java.util.HashMap;
import java.util.Map;
public class Main {
    public static void setProxy(boolean proxy) {
        if (proxy){
            HttpRequest.proxyHost("127.0.0.1");
            HttpRequest.proxyPort(8080);
        }
    }
    public static void main(String[] args) {
        //代理
        setProxy(false);
        //设置header头
        Map<String,String> Headers=new HashMap<String,String>();
        Headers.put("Cookie","RK=429ojE4A1p; ptcz=0dab32db1b9284ca7c7709c011daf934450981ea40e0a9e833b30f9b25299efb; pgv_pvid=8801185994; fqm_pvqid=a1642ff7-6dc0-4415-871a-113eb5180925; fqm_sessionid=9b75fa82-b8eb-4bf4-850a-f26c4da641e9; pgv_info=ssid=s3168114344; ts_uid=8507159015; _qpsvr_localtk=0.8180174642746458; ts_last=y.qq.com/; ts_refer=cn.bing.com/");
        Headers.put("Content-Length","661");
        Headers.put("Pragma","no-cache");
        Headers.put("Cache-Control","no-cache");
        Headers.put("Sec-Ch-Ua","\" Not A;Brand\";v=\"99\", \"Chromium\";v=\"99\", \"Google Chrome\";v=\"99\"");
        Headers.put("Accept","application/json");
        Headers.put("Content-Type","application/x-www-form-urlencoded");

        Headers.put("Sec-Ch-Ua-Platform","\"Windows\"");
        Headers.put("Origin","https://y.qq.com");
        Headers.put("Sec-Fetch-Site","same-site");
        Headers.put("Sec-Fetch-Mode","cors");
        Headers.put("Sec-Fetch-Dest","empty");
        Headers.put("Referer","https://y.qq.com/");
        Headers.put("Accept-Encoding","gzip, deflate");
        Headers.put("Accept-Language","zh-CN,zh;q=0.9,en-US;q=0.8,en;q=0.7,zh-TW;q=0.6");
        Headers.put("Connection","close");
        String Url= "http://u.y.qq.com/cgi-bin/musics.fcg?_=1647737559657&sign=zzb4b5adf4emghrndbrslfbaaohgt85qd8c2607f";
        String Data = "{"comm":{"cv":4747474,"ct":24,"format":"json","inCharset":"utf-8","outCharset":"utf-8","notice":0,"platform":"yqq.json","needNewCode":1,"uin":0,"g_tk_new_20200303":5381,"g_tk":5381},"req_1":{"module":"music.musicHall.MusicHallPlatform","method":"GetFocus","param":{}},"req_2":{"module":"newalbum.NewAlbumServer","method":"get_new_album_area","param":{}},"req_3":{"module":"newalbum.NewAlbumServer","method":"get_new_album_info","param":{"area":1,"sin":0,"num":20}},"req_4":{"module":"musicToplist.ToplistInfoServer","method":"GetAll","param":{}},"req_5":{"module":"MvService.MvInfoProServer","method":"GetNewMv","param":{"style":0,"tag":0,"start":0,"size":40}}}";
        //发送数据包
        HttpRequest res = HttpRequest.post(Url).headers(Headers).send(Data).followRedirects(false).readTimeout(5000);
        System.out.println(String.format("StatCode:%s",res.code()));
        System.out.println(String.format("Response:%s",res.body()));
    }
}

swing美化

com.formdev.flatlaf

一句话美化

FlatLightLaf.setup();
//按照自己喜欢的样式去setup即可

Java爬虫类

Jsoup

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import java.io.IOException;
public class Main {
    public static void main(String[] args) {
        Document document = null;
        try {
            //从URL加载文档，使用Jsoup.connect()方法从URL加载HTML
            document = Jsoup.connect("https://www.baidu.com/").get();
        } catch (IOException e) {
            e.printStackTrace();
        }
        //调用document.title()方法获取HTML页面的标题
        System.out.println(document.title());
    }
}

还可以携带参数


Document doc = Jsoup.connect("http://example.com")   
.data("query", "Java")   
.userAgent("Mozilla")   
.cookie("auth", "token")   
.timeout(3000)   
.post();

获取favicon

import com.github.kevinsawicki.http.HttpRequest;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
public class Main {
    public static void main(String[] args) {
        Document document = null;
        String favImage = "Not Found";
        String url = "https://i.hacking8.com/";
        try {
            document = Jsoup.connect(url).get();
            Element element = document.head().select("link[href~=.*\\.(ico|png)]").first();
            if (element == null)
            {
                element = document.head().select("meta[itemprop=image]").first();
                if (element != null)
                {
                    favImage = element.attr("content");
                }
            }
            else
            {
                favImage = element.attr("href");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println(document.title());
        if (favImage.contains("Not")){
            System.out.println("在源代码中没有找到图标");
            Map<String,String> Headers=new HashMap<String,String>();
            Headers.put("User-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.74 Safari/537.36");
            HttpRequest res = HttpRequest.post(url+"/favicon.ico").headers(Headers).followRedirects(false).readTimeout(5000);
            System.out.println(res.code());
            System.out.println(url+"/favicon.ico");
            if (res.code()==200){
                System.out.println(url+"/favicon.ico");
            }
        }else {
            System.out.println(url+favImage);
        }
    }
}

获取所有链接

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import java.io.IOException;
public class Main{
    public static void main(String[] args) {
        Document document;
        try {
            document = Jsoup.connect("https://i.hacking8.com/").get();
            Elements links = document.select("a[href]");
            for (Element link : links)
            {
                System.out.println("link : " + link.attr("href"));
                System.out.println("text : " + link.text());
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

多注重学习select过滤器
