这次问题很大！很严重！附代码！！上传文件不成功，why？

tool.h是我自己用来转换编码的文件 有需要的可以密我 此程序仅供 模拟浏览器 参考！！

问题在代码后和一楼给出

}

此次运行后 会出现文件上传一部分文件， 然后 GetLastError（）获得错误为12031 就是 网络链接重置
不知道这是为什么

我在HttpSendRequestExA 用的都不是宽字符 但是其他地方是宽字符，我在想是不是因为这个原因导致文件发送不成功，所以我在一楼的源码给出了，HttpSendRequestExW这个宽字符版本，但是现在更恶心的事情发生了， 就是HttpSendRequestExW竟然错误，错误代号87，就是参数不正确，看了无数遍，我的Buffin不可能有问题的，参数都符合条件。
现在我纠结了。。。。
