获取网站视频真实链接

直接上工具类

直接调用即可，这个工具类会返回加载的网页中所有的链接，至于对链接怎么处理就是你们自己的事了，亲测至今我所遇到的所有视频，它都可以捕获到其链接

调用

//初始化
this.parseWebUrlHelper=ParseWebUrlHelper.getInstance().init(this.mAct,"");
//解析网页中视频
parseWebUrlHelper.setOnParseListener(new ParseWebUrlHelper.OnParseWebUrlListener() {@Overridepublic void onFindUrl(String url) {Log.d("webUrl",url);//*****处理代码}@Overridepublic void onError(String errorMsg) {//****出错监听}

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

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
