Python爬取斗罗大陆全集

打开网址http://www.luoxu.cc/dmplay/C888H-1-265.html 

F12打开Fetch/XHR，看到m3u8，ts，一眼顶真，打开index.m3u8

由第一个包含第二个index.m3u8的地址，ctrl+f在源代码中一查index，果然有，不过/前总有个\，这个用replace替换为空

 查到第一个index.m3u8，就可以依次找到.ts地址

①爬取原网页，利用re找到第一个index地址

②再利用re找到第二个，然后爬取ts网页内容，添加到mp4文件中

③正则查找要用非贪婪模式，还有记得加上time.sleep()和timeout,以及user-agent要随机取（参考源码），要不然会有connection aborted，被反爬。。

④查看每一集的url的不同点，最后利用线程池一次性爬好几集（这里爬了1-10集），只要你内存够（
