进入到某网站，查看页面源代码
查看请求
对比一下，突破点
处理防盗链
# 1.拿到contId
# 2.拿到videoStatus返回的json. -> srcUrl
# 3. srcUrl 里面的内容进行修整
# 4. 下载视频
import requests
# 拉取视频的网址 -> 进入到指定某个视频页面源码
url = "https://www.pearvideo.com/video_1514115"
contId = url.split("_")[1]
videoStatusUrl = f"https://www.pearvideo.com/videoStatus.jsp?contId={contId}&mrd=0.543370355350492"
headers = {

# 防盗链：溯源，当前本次请求的上一级是谁
"Referer": url
}
resp = requests.get(videoStatusUrl,headers=headers)
dic = resp.json()
# print(dic)
srcUrl = dic['videoInfo']['videos']['srcUrl']
systemTime = dic['systemTime']
srcUrl = srcUrl.replace(systemTime,f"cont-{contId}")
# print(srcUrl)

# 下载视频
with open("PearFilm.mp4",mode="wb") as f:
