直接搜索就能夠定位到。

????????之前突然無意間發現斗魚舞蹈區，女主播熱舞真的灰常多，看的真的是熱血，年輕人就應該激情熱血些沒毛病吧，然后就想著把這些視頻都給用爬蟲下載下來，然后瘋狂抓包，一頓操作下來，發現需要驗證sign簽名，哎，沒辦法只能暫時放棄。最近放假的時間，閑著無聊沒事干就去斗魚找找舞蹈視頻看看，結果一發現！舞蹈區沒了！！！ （后來百度才得知，幾個月前舞蹈區就應為 “擦邊” 開始整改）結果整改整改，改著改著整個視頻區就不見了，這讓我們這些年輕人該怎么燃起激情！！

?1. 使用瀏覽器抓包分析

? ? ? ? 直接f12抓包分析，通常視頻采用的都是m3u8形式，一個片段一個片段的通過組合形成一個完整的視頻，有兩個文件返回了我們的m3u8，一個getStreamUrl? 一個playlist.m3u8，其實我們只用抓getStreamUrl這個就行，以為這個接口只要提交正確就會給我返回一個對應m3u8文件的url，視頻的每個片段內容都存在其中。

? ? ? ? ?我們看到，getStreamUrl提交了五個參數，其中tt，sign，vid分別對應我們的時間戳，簽名，視頻的編號id，v不確定是什么（但是是固定不變的），did為我們的設備號。vid我們可以在視頻的首頁拿到，我們只需要找出加密sign的函數，加載出sign就可以了，通常絕大部分的網站sign簽名都是對設備號，時間戳還有一些特定的參數（如getStreamUrl中的v）進行排序拼接，然后通過md5加密計算出來的值。

直接全局搜索.md5試試能不能直接定位到加密處。

2. 跟棧找出加密位置

?????????搜出來一堆，直接搜索這個方式不行，那我們就只能跟棧打斷點一步一步跟到加密處了，換到我們的initator這，然后點下面最后一次調用的地方跟進去，點進去不要動，會發現他自動跟到一個send發送的地方，在send處下一個斷點。

?看一下他發送的 r 是啥東西

? ? ? ? ?能夠發現啊，我們的sign就在其中，我們接著往上一個調用他的棧跟，跟到了一個return new Promise的地方，發現是傳過來的e里面帶有我們的sign，而且這個方法里也沒有重新定義我們的e，接著往上跟。

? ? ? ? ?跟到了(e.adapter || defaults_1.adapter)(e).then((function(t)所在的這個方法里頭，到這我們如果再繼續跟棧會發現，前面的棧都為異步加載的了，很難確定是先調用了哪個棧，并且這個還有一個then，看到then我們第一時間就應該想到異步，then會異步調用很多個方法，如果加密是在then里面，我們只能在此處下斷點，單步跟進去了，我們現在這個方法的頭部下斷，看看是不是在then處生成的e

? ? ? ? ????????刷新網頁，重新斷到我們下斷的位置

? ? ? ? 發現沒有經過then，我們的e中就已經有sign了，在data當中，我們再向上跟棧。

????????跟到了一個?n = n.then(t.shift(), t.shift()) ，我們在頭部繼續下斷點，發現傳進來的e還是有data，說明并不是在此處進行的加密。繼續跟棧，發現我們跟到了一個大方法里，向上翻并沒有e傳入，下斷分析

? ? ? ? ?刷新網頁，斷在此處，把return括起來看一下，發現并沒有data，說明data是在這個return處和上一個斷點之間生成的，到這里已經很接近了，仔細分析分析

? ? ? ? 直接在bind$1這個方法里，四行全部下斷點，一個一個斷點跟。

? ? ? ? 第一步，e為空

第二步，e為空?

?第三步，發現e還是為空

這就奇怪了，明明跟到了這個地方，卻沒有產生data？不要慌，我們仔細看看

e.apply里面傳遞了兩個參數，其中的n就有我們想要的data

????????這時候我們只需要網上看，n是在哪產生的，注意看上一行 n[r] = arguments[r] 所以我們n中的data是從arguments中來的，看看arguments是從哪來的，繼續跟到上一個?？纯?。

?????????最后是在上一個方法棧里頭的 var p = window[l](a, o, s);處，p中就包含了我們想要的sign，下面的t = "".concat(p, "&vid=").concat(r)不用管，只是在后面拼接了一個視頻的vid。不難看出p是由window[l]里面的三個參數 a，o，s加密產生的，這里大家自行去看看就好了，a是固定值，可以定死，o是設備號，s為時間戳，我們括住window[l]看看他是怎么加密的，把加密方法扣出來就行，最后是跟到了這里，大家自行格式化代碼就能拿到加密的方法啦。

?????????附上摳出來的js代碼

大家扣完放到node里運行可能會報出CryptoJS不存在的錯，兩種解決方法，一是去補jQuery，二是直接用nodejs里的CryptoJS

nodejs CryptoJS 安裝方法 === >? ? npm install?crypto-js

?

然后在js代碼頭部寫入const CryptoJS = require('crypto-js');

?完成。
