爬取步骤

第一步：获取视频所在的网页

第二步：F12中找到视频真正所在的链接

第三步：获取链接并转换成二进制

第四部：保存

保存步骤代码

import requests
response =  requests.get('https://vd4.bdstatic.com/mda-jcrx64vi5vct2d2u/sc/mda-jcrx64vi5vct2d2u.mp4?auth_key=1557734214-0-0-d6a29a90222c6caf233e8a2a34c2e37a&bcevod_channel=searchbox_feed&pd=bjh&abtest=all')
video = response.content         #把文件保存成二进制
with open(r'D:\图片\绿色.mp4','wb') as fw:
    fw.write(video)           #将文件内容写入该文件
    fw.flush()               #刷新
