get和post体现在HttpOpenRequest和HttpSendRequest上的区别
服务端用http\https编程，客户端用socket

HINTERNET WINAPI HttpOpenRequest(
HINTERNET hConnect,
LPCTSTR lpszVerb,
LPCTSTR lpszObjectName,
LPCTSTR lpszVersion,
LPCTSTR lpszReferrer,
LPCTSTR *lplpszAcceptTypes,
DWORD dwFlags,
DWORD dwContext );

BOOL WINAPI HttpSendRequest(
HINTERNET hRequest,
LPCTSTR lpszHeaders,
DWORD dwHeadersLength,
LPVOID lpOptional,
DWORD dwOptionalLength);

[解决办法]
HttpOpenRequest 第二个参数用"GET", "PUT",还可以用服务器支持的命令
[解决办法]
API参数传递的时候指定GET还是POST操作
