第一次接触VC++模拟HTTP协议的POST方式提交表单。POST提交部分的代码是在网上找的现成的函数，里面使用的是MFC的CHttpConnection类。随便找了个没有验证码的注册页面（考试吧网站的注册页面），提交表单，抓到数据包后分析，模拟提交，测试成功！于是便写出了这个批量注册的程序。为以后写更强大的模拟提交表单程序打基础。利用这种模拟提交和获取数据的方法，完全可以把一个别人写好的现成的B/S架构客户端网页写成一个C/S架构的客户端软件。十分强大！还可以进行各种代替人工操作的模拟网页操作。

本程序中用到了多线程，界面主线程和注册账号的工作者线程分开处理，但工作者线程只有一个，同时只能发起一个网络连接，注册速度较慢，待改进。

-First contact VC++ simulate HTTP POST protocol submission form. POST submission part of the code is readily available on the Internet to find a function, which uses the MFC CHttpConnection classes. Just looking for a no verification code registration page (bar exam registration page website), submit the form, caught after packet analysis, simulation submit, the test is successful! So they wrote the bulk registration process. Laying the foundation for the subsequent procedures to submit the form to write more powerful simulations. Using this simulation method to submit and retrieve data, can someone put a ready-written B/S architecture client pages written in a C/S structure of the client software. Very powerful! You can also perform a variety of operations simulation instead of doing web operations. The program uses a multi-threaded, the main thread and the worker thread interface registered account separately, but only one worker thread, but can only initiate a network connection, a r
