下载酷狗音乐的PYTHON代码 java酷狗音乐
| 与你一起成长 作者：后山悟道人 下文方法及代码仅供学习使用，不做他用。示例用到了一些库，包括：jsoup、HttpClient、net.sf.json大家可以自行去下载jar包。 1.分析是否能获得TOP500歌单首先，打开酷狗首页查看酷狗TOP500，说好的500首，怎么就只有22首呢？
是真的只让看这些还是能找到其余的呢，于是我就看了下这TOP500的链接 https://www.kugou.com/yy/rank/home/1-8888.html?from=rank 可以看的出home后边有个1，难道这是代表第一页的意思？于是我就把1改成2，进入，果然进入了第二页， 至此可以知道我们可以在网页里获取这500首的歌单。 2.分析找到真正的mp3下载地址(这个有点绕)点一个歌曲进入播放页面，使用谷歌浏览器的控制台的Elements，搜一下mp3，很轻松就定位到了MP3的位置
但是使用java访问的时候爬取的html里却没有该mp3的文件地址，那么这肯定是在该页面的位置使用了js来加载mp3，那么刷新下网页，看网页加载了哪些东西，加载的东西有点多，着重看一下js、php的请求，主要是看里面有没有mp3的地址，分析细节就不用说了
最终我在列表的 https://wwwapi.kugou.com/yy/index.php?r=play/getdata&callback=jQuery191027067069941080546_1546235744250&hash=667939C6E784265D541DEEE65AE4F2F8&album_id=0&_=1546235744251这个请求里发现了mp3的完整地址， "play_url": "http:\/\/fs.w.kugou.com\/201812311325\/dcf5b6449160903c6ee48035e11434bb\/G128\/M08\/02\/09\/IIcBAFrZqf2ANOadADn94ubOmaU995.mp3",那这个js是怎么判断是哪首歌的呢，那么只可能是hash这个参数来决定歌曲的，然后到播放页面里找到这个hash的位置，是在下面的js里 var dataFromSmarty = [{"hash":"667939C6E784265D541DEEE65AE4F2F8","timelength":"237051","audio_name":"\u767d\u5c0f\u767d - \u6700\u7f8e\u5a5a\u793c","author_name":"\u767d\u5c0f\u767d","song_name":"\u6700\u7f8e\u5a5a\u793c","album_id":0}],//当前页面歌曲信息 playType = "search_single";//当前播放在去java爬取该网页，查看能否爬到这个hash，果然，爬取的html里有这段js，到现在mp3的地址也找到了，歌单也找到了，那么下一步就用程序实现就可以了。 3.java实现爬取酷狗mp3先看一下爬取结果
找到了资源，程序实现就好说了，其中使用到了自己写的几个工具类，自己整理点自己的工具类还是有好处的，以后遇到什么问题就没必要重新写了，直接拿来用就可以了。没什么好说的了，下面直接贴出源码 SpiderKugou.java package com.bing.spider; import java.io.IOException; import java.util.regex.Matcher; import java.util.regex.Pattern;
