使用WinInet进行文件上传时，需要用到的参数较为分散，导致传参的时候，只能定义几个接口来实现。但是，通过使用InternetCrackUrl 分解URL后，就可以一次性把需要的参数都拿到了！

#include "stdafx.h"
    #include <Windows.h>
    #include <wininet.h>
    #pragma  warning(disable:4189)
    #pragma comment( lib, "WinInet.lib" )
    
    void CrackUrl()

    	TCHAR ExtraInfo[1000];
    
    	URL_COMPONENTS uc;
    	uc.dwStructSize = sizeof(uc);
    	uc.lpszScheme = Scheme;
    	uc.lpszHostName = HostName;
    	uc.lpszUserName = UserName;
    	uc.lpszPassword = Password;
    	uc.lpszUrlPath = UrlPath;
