爬虫 python的第一天
1、安装pycharm及python相关的安装
2、新建python项目
3、引包 import requests
pip install requests
4、打开网页，找打你想要爬的数据URL
5、写代码获取到对应的数据，保存到本地。
import requests url = "https://sns-video-al.xhscdn.com/stream/110/259/01e640315b0ef9f2010371038f6acf0431_259.mp4" req = requests.get(url) # 请求地址 print(req.content) # 打印请求地址的返回的内容 name = "小三" # 下载到本地，参数1为保存到本地的文件名（任意名字），参数2为操作，读写w(write),r(read),wb(写二进制文件，如视频、音频)，rb(读二进制文件) open("测试.txt", "w").write(name) open("测试1.mp4", "wb").write(req.content)
6、最后看到一个免费看各大会议视频的代码，也给大家分享一下

把上面代码保存成一个html，如
然后直接打开，输入你看不了的VIP视频链接确认即可免费收看
