爬虫爬答案_爬虫0基础?

有的网站会有referer,就是找到你从那个链接访问的当前页面

import requests
url = 'https://www.pearvideo.com/video_1756291'
headser = {
    "User-Agent":"Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36",
    # 防盗链:溯源 当前请求的上一级
    "Referer":url
}

contId = url.split("_")[1]
vidoStaut = 'https://www.pearvideo.com/videoStatus.jsp?contId=1756291&mrd=0.5111732520670023'

resp = requests.get(vidoStaut,headers = headser)
dic = resp.json()
srcurl = dic['videoInfo']['videos']['srcUrl']
systemTime = dic['systemTime']
srcurl = srcurl.replace(systemTime,f"cont-{contId}")  #拼接替换replace

#下载视频

with open("a.mp4",mode="wb") as f:
    f.write(requests.get(srcurl).content)
f.close()
print("OVER")

这样就能获取到视频的链接下载了
