基于http的接口越来越多，除了看接口文档，更多时候都需要着搭配不同的参数去实际请求一下，看看返回值，很多open api都有附带网页版的调试工具来做这个事情，例如淘宝api测试工具

开发的时候，往往都会在测试服务器上搭建接口服务供开发调试，为了避免互相影响，不同的开发小组也会有不同的接口测试服务器，这样一来，就需要在运行代码的机器上设置host，用同样的域名来请求不同的服务器

近来想用php做一个通用的、网页版的http接口测试工具，那上述的host设置就成了一个问题，假设有两个开发小组同时来使用这个工具，用同样的域名请求同样的接口，但http请求却需要发送到不同的服务器，改服务器的host肯定是不行了

接下来的思路比较极端，用php做socket编程，自己构造tcp请求和http请求自然为所欲为，http协议虽然简单，但此做肯定会遇到很多现在没考虑到的细节问题，再加上好好的curl摆着不用也觉得可惜，把curl的option翻了一遍，没有找到适合的选项，但想想也不奇怪，我这个需求比较另类，怨不得curl，再仔细想想，在协议层面，tcp在4层，http在7层，两层并不依赖，想办法避免tcp目标主机由url的host解析而来即可，于是试了试curl的http proxy相关选项，成功！PHP代码如下

刚群里黑哥丢出个乌云的链接：http://www.wooyun.org/bugs/wooyun-2012-06420

问谁上，我说我上吧，职业病，看到discuz dede啥的漏洞一下就精神了，哈哈……

过程简单说下，记的有点乱不贴太多代码了

diff一下看
