小編給大家分享一下Python爬取嗶哩嗶哩視頻的示例，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！
我這里使用的是環境如下僅供參考：
開發工具： pycharm
python環境：python-3.8.0
依賴的包： shutil，os，re，json，choice，requests，lxml
我在這里就拿前段時間非常火的馬老師的視頻來舉例子吧。
視頻鏈接： https://www.bilibili.com/video/BV1Ef4y1i78b?from=search&seid=12072538764197074893
video后面？ 號前面</script><script>中的內容返回一個json串解析獲取我們想要的數據即可。. 
返回給我們的們如下,真正對我們有用的信息在data中
在data 下面我們就可以清晰的看到我們想要的內容了，如視頻的畫質，以及視頻的地址等，注意：如果你拿到地址直接進行訪問的話是訪問不到了，嗶哩嗶哩中添加了Referer如果你直接在瀏覽器訪問是沒有Referer的是找不到頁面的。
我們需要解析的內容如下：
依賴的包
import jsonimport osimport reimport shutilimport sslimport timeimport requestsfrom concurrent.futures import ThreadPoolExecutorfrom random import choicefrom lxml import etree
添加請求頭和隨機用戶代理
#設置請求頭等參數，防止被反爬headers = {
