referer的反爬和爬虫下载视频

一、缘由

　　在梨视频等一些网站中会使用防盗链作为反爬的基础方法，这个反爬并不严重，只是平时的时候需要多加留意。此次实现对应链接中梨视频的下载。

二、代码实现

　　

#1、拿到contid
#2、拿到videoStatus返回的json.->  srcURL
#3、srcURL里面的内容进行修整  成为src
#4、下载视频

import requests

url="https://www.pearvideo.com/video_1731253"
contID=url.split("_")[1]

videoStatus=f"https://www.pearvideo.com/videoStatus.jsp?contId={contID}&mrd=0.1439190374449233"
headers={

    "Referer": url
}
resp=requests.get(videoStatus,headers=headers)
dic=resp.json()
srcURL=dic["videoInfo"]["videos"]["srcUrl"]
systemTime=dic["systemTime"]
url_=srcURL.replace(systemTime,"cont-"+contID)

with open(r'C:\Users\sunshine\Desktop\i'+contID+".mp4","ab+") as f:
    f.write(requests.get(url_).content)
print('over')
