Python爬取酷狗音乐TOP500 !

2019年5月18日 158次阅读来源: 不谈风月_0eb8

发这个主要是因为我本地没有歌，有的歌还是VIP下载不了，平时听歌还得用流量。所以就想着看能直接把所有的歌曲直接拿下来。就去看了酷狗的主页面。想直接拿到TOP500.因为没找到怎么去下载，然后就在网上找了一下，找到了一个根据hash拼接url，下载歌曲。，只要找到hash值就啥都解决了。

看了之后发现还不是特别难弄，所以就直接趴下来了。

上面是网址，

<tt-image data-tteditor-tag=”tteditorTag” contenteditable=”false” class=”syl1556264619770 ql-align-center” data-render-status=”finished” data-syl-blot=”image” style=”box-sizing: border-box; cursor: text; text-align: left; color: rgb(34, 34, 34); font-family: “PingFang SC”, “Hiragino Sans GB”, “Microsoft YaHei”, “WenQuanYi Micro Hei”, “Helvetica Neue”, Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;”>

改变数字就可以实现翻页，所以这个不能翻页的问题解决了。然后就是老套路按F12查看找network.

<tt-image data-tteditor-tag=”tteditorTag” contenteditable=”false” class=”syl1556264619772 ql-align-center” data-render-status=”finished” data-syl-blot=”image” style=”box-sizing: border-box; cursor: text; text-align: left; color: rgb(34, 34, 34); font-family: “PingFang SC”, “Hiragino Sans GB”, “Microsoft YaHei”, “WenQuanYi Micro Hei”, “Helvetica Neue”, Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;”>

完整项目地址可以添加QQ源码群1004391443，有飞机大战、颜值打分器、打砖块小游戏、红包提醒神器、小姐姐表白神器等具体的实训项目，有清晰源码，有相应的文件

往下翻，发现这些都有注释，那就更好办了。

解析这个数据，拿出来hash值和filename，歌词lyric。

也没什么要说的了，直接贴代码
