一、環境

JDK 1.8+

二、 步驟

1. 開啟網易雲音樂中的其中一首歌頁面，然後開啟開發者工具，檢視mv連結地址

3. 開啟mv連結地址後，檢視網頁框架原始碼

4. 發現視訊的地址就是這裡<meta content='">中，用Jsoup進行解析，這裡的url可以用URLDecode 進行解碼，我們可以複製url到線上解碼網站去進行解碼， 線上加/解碼 地址： http://www.convertstring.com/zh_CN/EncodeDecode/UrlDecode

解碼後的url是這樣的：

複製解碼後的網址進行訪問：

視訊的源播放地址就出來了，這時候就可以進行下載

下面給出原始碼（Java）

三、 原始碼
