1、酷狗音樂型md5加密給我上身體（這應該就是加密了吧，，要不然挺尷尬T_T），我這個不是爬取酷狗TOP500，而是搜索之后在下載歌曲
如下圖上，當你播放歌曲跳到另一個頁面（酷狗有一個專門播放歌曲的頁面），F12打開network，然后刷新頁面，就會發現歌曲下載地址在下圖所示類型數據包中
2、然后我們去分析它的請求頭
https://wwwapi.kugou.com/yy/index.php?r=play/getdata&callback=jQuery1910026577801017397817_1596164131720&hash=AC9B095DCF364F751BCED2E148638AFA&album_id=&dfid=0zPSYM1q2qH90xArIr1yOGtc&mid=5cd316b98602d9b29f31085c96e6c682&platid=4&_=1596164131721
他用的get請求將參數加到鏈接后面，我們只需要分析一下參數就可以了，這里我就直接說結果了
只需要它的hash值改變，那么這個請求鏈接就是那首歌的信息
也就可以說hash值相當於歌曲的唯一標識id
3、然后我們去找hash值，剛開始以為hash值是在js文件中生成的，搜索之后部分js代碼如下
找了半天都沒有找到是怎么來的，代碼里面好像option就是參數，其他地方直接傳過來的，，，那么估計hash值不是js中生成的了，那么就去其他文件里面找找有沒有這個hash值的來源
在這個文件中有歌曲的信息，你把列表信息打開，就會發現有一個FileHash，和哪個一對比，果然一樣
（我的不一樣，是因為這兩首歌都不一樣，我只是給你們說一下過程，不要在意細節）
然后我們就要去分析這個數據包的請求頭
https://complexsearch.kugou.com/v2/search/song?callback=callback123&keyword=%E7%A8%BB%E9%A6%99&page=1&pagesize=30&bitrate=0&isfuzzy=0&tag=em&inputtype=0&platform=WebFilter&userid=-1&clientver=2000&iscorrection=1&privilege_filter=0&srcappid=2919&clienttime=1596167570360&mid=1596167570360&uuid=1596167570360&dfid=-&signature=BA1355A64A559B7A779E96825A7631E8 callback: callback123 keyword: 稻香 page: 1 pagesize: 30 bitrate: 0 isfuzzy: 0 tag: em inputtype: 0 platform: WebFilter userid: -1 clientver: 2000 iscorrection: 1 privilege_filter: 0 srcappid: 2919 clienttime: 1596167570360 mid: 1596167570360 uuid: 1596167570360 dfid: - signature: BA1355A64A559B7A779E96825A7631E8
這個請求也是get請求，我們分析它的參數就可以了，你多分析幾個這樣的數據包，看一下參數就會看出來那些值在改變，這里我說結果
clienttime和mid和uuid和signature一直在改變，而且clienttime和mid和uuid的值都一樣
然后我們就就接着去找js代碼
大致一找就會發現clienttime和mid和uuid的值都是時間戳（我怎么說看着這么眼熟），但是沒有signature
o.join方法就是把o這個列表里面的信息變成一個字符串，例如：
<script type="text/javascript"> var arr = new Array(3) arr[0] = "George" arr[1] = "John" arr[2] = "Thomas" document.write(arr.join()) </script> 輸出： George,John,Thomas
我們斷點調試發現o里面的數據是
0: "NVPh5oo715z5DIWAeQlhMDsWXXQV4hwt" 1: "bitrate=0" 2: "callback=callback123" 3: "clienttime=1596179805676" 4: "clientver=2000" 5: "dfid=-" 6: "inputtype=0" 7: "iscorrection=1" 8: "isfuzzy=0" 9: "keyword=稻香" 10: "mid=1596179805676" 11: "page=1" 12: "pagesize=30" 13: "platform=WebFilter" 14: "privilege_filter=0" 15: "srcappid=2919" 16: "tag=em" 17: "userid=-1" 18: "uuid=1596179805676" 19: "NVPh5oo715z5DIWAeQlhMDsWXXQV4hwt" length: 20
然后我們去看faultylabs.MD5代碼
1 faultylabs.MD5 = function(a) { 2 function b(a) { 3 var b = (a >>> 0).toString(16); 4 return "00000000".substr(0, 8 - b.length) + b 5 } 6 function c(a) { 7 for (var b = [], c = 0; c < a.length; c++) 8 b = b.concat(k(a[c])); 9 return b 10 } 11 function d(a) { 12 for (var b = [], c = 0; 8 > c; c++) 13 b.push(255 & a), 14 a >>>= 8; 15 return b 16 } 17 function e(a, b) { 18 return a << b & 4294967295 | a >>> 32 - b 19 } 20 function f(a, b, c) { 21 return a & b | ~a & c 22 } 23 function g(a, b, c) { 24 return c & a | ~c & b 25 } 26 function h(a, b, c) { 27 return a ^ b ^ c 28 } 29 function i(a, b, c) { 30 return b ^ (a | ~c) 31 } 32 function j(a, b) { 33 return a[b + 3] << 24 | a[b + 2] << 16 | a[b + 1] << 8 | a[b] 34 } 35 function k(a) { 36 for (var b = [], c = 0; c < a.length; c++) 37 if (a.charCodeAt(c) <= 127) 38 b.push(a.charCodeAt(c)); 39 else 40 for (var d = encodeURIComponent(a.charAt(c)).substr(1).split("%"), e = 0; e < d.length; e++) 41 b.push(parseInt(d[e], 16)); 42 return b 43 } 44 function l() { 45 for (var a = "", c = 0, d = 0, e = 3; e >= 0; e--) 46 d = arguments[e], 47 c = 255 & d, 48 d >>>= 8, 49 c <<= 8, 50 c |= 255 & d, 51 d >>>= 8, 52 c <<= 8, 53 c |= 255 & d, 54 d >>>= 8, 55 c <<= 8, 56 c |= d, 57 a += b(c); 58 return a 59 } 60 function m(a) { 61 for (var b = new Array(a.length), c = 0; c < a.length; c++) 62 b[c] = a[c]; 63 return b 64 } 65 function n(a, b) { 66 return 4294967295 & a + b 67 } 68 function o() { 69 function a(a, b, c, d) { 70 var f = v;

我感覺我已經分析不出來了，兄弟們，誰要是弄出來了給我說一說可不^_^,我感覺太太太太太復雜了！！！！！
雖然我們不能從頭開始模擬，但是我們可以下載一首歌曲找到這首歌曲的hash值，然后再去模擬請求
這也是沒有辦法中的辦法了，唉，沒辦法，，，這加密我也看不懂呀(但是代碼還是可以爬取vip音樂)
注意：
請求到的數據包不是json格式，不能轉化成字典了，，，唉，，，，，可以用re模塊來弄
然后就是最后歌曲的鏈接也需要處理一下，因為原鏈接里面包含"\"
