引言：剛開始我想要爬取微博的照片，但是發現網上大多數的blog都是需要一個cookie的東西，當時我很難得到，偶然翻到一個個人的技術博客：
http://www.omegaxyz.com/2018/02/13/python_weibo/
(順便推薦一下他的博客吧，裏面有很多幹貨）））
試了一下，效果還是很好的：

這裏唯一需要的一個user的id，id = '2374240301’這一行，可以自己修改，關於怎麼獲取user的id，也很簡單：
從微博中打開一個博主的微博：
看一下右上角的地址欄：
上面的這個圖片就是：
https://weibo.com/u/1658996247?refer_flag=1087030701_2975_2003_0&is_hot=1
其中1658996247就是usr的id了，把這個粘貼過去就好，運行代碼，可以看到我們的路徑裏爬取的圖片:
