不知從何時開始我們手機音樂app里的歌單,好多歌曲不是變灰了就是變成vip歌曲,普通用戶只能試聽幾十秒,作為一名白嫖黨怎么能忍,干脆擼起袖子自己動手把喜歡的歌曲全部保存下來。
- 咕米音樂網頁版:https://music.migu.cn/v3
說句題外話我覺得咕米音樂這個網站真的挺良心的,個人很喜歡,幾乎所有的音樂都可以無損播放。簡直不要太友好。不像某些大廠吃相太難看了,試聽只能普通音質,想要無損必須辦會員,那渣音質還不如不聽。關鍵是咕米音樂還能免費聽周董的歌【笑】
打開咕米音樂首頁,搜索自己喜歡的歌手進入他的主頁,如下圖:
點擊播放一首音樂,頁面進行跳轉,右鍵F12打開開發者模式重新刷新頁面,如圖所示:
我們分析請求信息得出如下鏈接即為歌曲請求的api
在response里便是服務端返回的歌曲信息
分析請求的參數,搜索參數名稱有如下結果,很容易就定位到加密參數的生成位置
打個斷點進行單步調試,變量e即為被加密的數據,經多番測試,其中copyrightId即歌曲的版權id;
type為音樂的音質類型,無損SQ type == 3,高質量HQ type == 2,普通音質 type == 1
auditionsFlag默認為0;變量n為固定值;變量 r、a即為我們提交的加密參數。
好了基本上分析完了,此處省略摳js代碼過程。
三、具體實現
