小番在这里
这里涉及了一些反爬手段与方法，老铁们赶紧拿起小板凳开始听了哦

爬取思路：

打开一个番剧，找到播放页面，开始F12 检查元素发现直接跳回首页了，这就没法用浏览器自带的抓包了。可以使用抓包工具fiddle进行抓包。先不急着抓包，先看看播放页的源代码
view-source:www.zzzfun.com/vod_play_id_2029_sid_1_nid_1.html

可以得到每一话的链接，那么还少了视频链接，网页源代码里面没有，只能抓包了。

可以发现debug调试时跳转的代码，在右下角窗口中继续找有用的信息，找到了m3u8链接

经过测试，这个链接时效性很短，使用requests库保存为.m3u8后缀，用txt文件类型打开后发现很多链接，如图，这就是我们需要下载的了，有老铁怀疑这里面的链接会不会变啊，抓包分析不断比对同一集m3u8里的这个链接，发现这个链接是不变的哦，只有那个m3u8会变的hahah~~

将它们提取出来，下载下来又该怎么合成呢，其实使用requests库以ab形式追加将二进制内容写入一个文件，就行了，这是其他的读写文件参数一篇搞懂python文件读写操作（r/r+/rb/w/w+/wb/a/a+/ab）

这样我们的基本思路就完成了，剩下只需要将这个链接请求获得m3u8地址，之后下载即可，而这个链接是有规律的（与刚开始打开的一部番剧主页面有关哦），大家可以自行抓包尝试一下哦~~

遇到的坑：

但是这个完整视频下载下来后，我用的爱奇艺播放器竟然打不开，就很纳闷用了potplayer,还是挺香的，可以正常播放，大家要是不能播放可以换换播放器哦

小结

• 使用{:0>2d}在数字前面补0满足两位数，如{:0>2d}.format(3),补0后结果为03
• 由于番名是由图片嵌上去的，就使用了百度AI的文字识别接口，很简单，先登录百度智能云，左侧选择文字识别，创建应用
  将API Key 和Secret Key 写入代码即可，代码里依旧保存我的AK和SK，大家有兴趣的话可以替换成自己的就可以运行啦，（详细的文档说明），如果由于某种原因失败，会默认创建‘番剧’的文件夹，要下载的番剧视频就在那里面哦
• 番名的那个图片Url需要用requests带headers下载，用request.urlretrieve会下载失败

注意

如果出现·
list index out of range报错，请检查网站页面是否变成了

点一下继续访问即可
