各位小夥伴，之前一段時間迷上了抖音小姐姐視訊，但是下載的視訊都有水印，於是自己用Python 寫了個爬取小姐姐視訊的工具，大家可以直接拷貝到自己編譯器上執行。此外，我還利用pyqt5寫了個操作介面，這樣可以方便不懂程式碼的人使用。後面程式碼我都會一一貼上來。備註：這個只是個人興趣，參考程式碼的小夥伴切莫用於非法商業途徑；

環境：python3.0    pychram/eric  

url 獲取方式：頁面右邊的【分享】按鈕-》 複製連結。  提取出裡面的Url就好了。

雜七雜八：Python開發者可以加我一下，多交流交流，我的微信：stefan1240。 

另外這段時間閒著沒事，自己弄了個淘客網站。領取天貓淘寶優惠券的，和一般的找券網不同，採集下來的天貓淘寶產品都是經過我的大資料模型篩選的，希望大家幫忙測試下，網頁右上角有安卓app下載。

直接上正文程式碼：

遇到下載不通的話，自己看看程式碼哈。

我自己做的客戶端是用Pyqt5寫的，程式碼的話是好幾個資料夾，我就不貼出來了，原始碼可以找我索要。上個介面圖吧：
