WIN32中给服务器post数据的问题---WinHttpOpen

[mfcwtl]

想给网页端post数据，用的msdn上的例子，

int APIENTRY _tWinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPTSTR lpCmdLine, int nCmdShow)
{
	TCHAR *p=L"http://1.2.3.4:9090/mysoft/azAction.action?ip=127.0.1.3&name=1";
	TCHAR *h=L"Content-Type: application/x-www-form-urlencoded";
   DWORD dwSize = 0;
    DWORD dwDownloaded = 0;
    LPSTR pszOutBuffer;
    BOOL  bResults = FALSE;
    HINTERNET  hSession = NULL, 
               hConnect = NULL,
               hRequest = NULL;

    // Use WinHttpOpen to obtain a session handle.
    hSession = WinHttpOpen( L"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322",  
                            WINHTTP_ACCESS_TYPE_DEFAULT_PROXY,
                            WINHTTP_NO_PROXY_NAME, 
                            WINHTTP_NO_PROXY_BYPASS, 0);

    // Specify an HTTP server.
    if (hSession)
        hConnect = WinHttpConnect( hSession, L"1.2.3.4",
                                   /*INTERNET_DEFAULT_HTTPS_PORT*/9090, 0);

    // Create an HTTP request handle.
    if (hConnect)
        hRequest = WinHttpOpenRequest( hConnect, L"POST", L"/mysoft/azAction.action?",
                                       NULL,  L"Content-Type: application/x-www-form-urlencoded", 
                                       WINHTTP_DEFAULT_ACCEPT_TYPES, 
                                       WINHTTP_FLAG_SECURE);
//听说要加http头自己加的
	WinHttpAddRequestHeaders(hRequest,h,lstrlen(h),0);

    // Send a request.
    if (hRequest)
        bResults = WinHttpSendRequest( hRequest,
                                       WINHTTP_NO_ADDITIONAL_HEADERS,
                                       0, p, lstrlen(p), 
                                      lstrlen(p), 0);

	DWORD n=GetLastError();
    // End the request.

    // Close any open handles.
    if (hRequest) WinHttpCloseHandle(hRequest);
    if (hConnect) WinHttpCloseHandle(hConnect);
    if (hSession) WinHttpCloseHandle(hSession);

DWORD n=GetLastError();n=12175
请问大家我该如何修改呢，谢谢各位。

引用 3 楼 fishion 的回复:

1.2.3.4，这IP能连吗。。

故意修改的，不关这里的事呢

Debug一下，哪个函数调用失败了？
