他人总结
1.http://www.cnblogs.com/lee0oo0/p/4026774.html
获取webview完整源码[包括iframe源码]
主要问题
动态加载
iframe嵌套
0.window也算一个frame 1.得到frame 2.判断frame的url是否已被查找 3.判断frame是否是同域名 4.同域名直接正常查找 5.不同域名直接单独加载frame的url当成一个新的页面处理 6.一直查找直到发现一个video标签
iframe链接单独打开被检测到问题
次要问题
去除Chrome反调试
无限断点反调试
参考https://blog.csdn.net/zzgzzg00/article/details/79504827
完结
编程这种事真是太容易跑偏了我明明最根本的目的就是为了获取网站视频链接的然后发现有些网站的源码获取不全然后目的就悄然变成了去获取源码然后折腾了几天依然没解决这个获取源码的问题然后猛然记起以前研究过相同的问题并且还写了一篇获取视频链接的文章这才是真正的造轮子吧明明已经研究过一次了相同的问题明明已经遇到过一次了为何这次又掉坑里了而且掉坑里几天了居然没意识过来唉笨啊真实不长记性啊到了最后才发现我获取源码的目的就是为了获取视频链接说来还是我以前写的这篇文章发挥了作用Web逆向之通过Android中WebView获取网站视频真实链接
