本篇文章主要給大家講解下如實使用python 爬取嗶哩嗶哩中的視頻，首先我是一名大數據開發工程師，爬蟲只是我的一個業余愛好，喜歡爬蟲的小伙伴可以一起交流。好了多了就不多說了喜歡的朋有可以收藏，轉發請復原文鏈接謝謝

一、環境準備

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，lxmlBuY少兒編程網-Scratch_Python_教程_免費兒童編程學習平臺

二、頁面分析

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=12072538764197074893BuY少兒編程網-Scratch_Python_教程_免費兒童編程學習平臺

視頻鏈接解析 我們這里只需要 BV1Ef4y1i78b 也就是 video后面？ 號前面第二部分抓包，嗶哩嗶哩這里的視頻被分成多個小段了經過看源碼分析后我們可以解析</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。. 分析返回json中的具體內容

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：BuY少兒編程網-Scratch_Python_教程_免費兒童編程學習平臺

視頻的時長視頻的質量視頻的URL音頻的URL音頻和視頻合并
三、代碼實操3.1 準備工作

依賴的包BuY少兒編程網-Scratch_Python_教程_免費兒童編程學習平臺
