我这里使用的是环境如下仅供参考:
开发工具: pycharm
python环境:python-3.8.0
依赖的包: shutil,os,re,json,choice,requests,lxml
我在这里就拿前段时间非常火的马老师的视频来举例子吧。
视频链接: https://www.bilibili.com/video/BV1Ef4y1i78b?from=search&seid=12072538764197074893
video后面? 号前面
</script><script>
中的内容返回一个json串解析获取我们想要的数据即可。. 返回给我们的们如下,真正对我们有用的信息在data中
在data 下面我们就可以清晰的看到我们想要的内容了,如视频的画质,以及视频的地址等,注意:如果你拿到地址直接进行访问的话是访问不到了,哔哩哔哩中添加了Referer
如果你直接在浏览器访问是没有Referer的是找不到页面的。
我们需要解析的内容如下:
依赖的包
import jsonimport osimport reimport shutilimport sslimport timeimport requestsfrom concurrent.futures import ThreadPoolExecutorfrom random import choicefrom lxml import etree
添加请求头和随机用户代理
#设置请求头等参数,防止被反爬headers = { 'Accept': '*/*', 'Accept-Language': 'en-US,en;q=0.5', 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.116 Safari/537.36'}def get_user_agent(): '''获取随机用户代理''' user_agents = [ "Mozilla/4.0 (compatible;
