Question

我在使用此代码将数据发送到php服务器时遇到了非常严重的问题。 c ++应用程序发送数据，但是它不是正确地发送数据，而是当我从数据库中查看时它只显示参数中的空字段，可能是什么错误？我的代码就像这样

#include <stdio.h>
#include <windows.h>
#include <string.h>
#include <Wininet.h>

#define PAGE_NAME "gate.php"

#pragma comment (lib, "wininet")

void compName()
    {
    LPCSTR compName = getenv("COMPUTERNAME");
    printf("Computer name is : %s\n",compName);

    }


void userName()
{
    LPCSTR userName = getenv("USERNAME");
    printf("UserName is : %s\n",userName);

}

void hWid()
{
    HW_PROFILE_INFO hwProfileInfo;
    if(GetCurrentHwProfile(&hwProfileInfo))
    {
    LPCSTR hWid = hwProfileInfo.szHwProfileGuid;
    printf("HWID: %s\n",hWid);
    }
}

void ip()
    {
      HINTERNET hInternet , hFile;
      DWORD rSize;
      char ip[50];
      hInternet = InternetOpen(NULL,INTERNET_OPEN_TYPE_PRECONFIG,NULL,NULL,0);
      hFile = InternetOpenUrlA(hInternet,"http://housenaija.com/ip/ip.php",NULL,0,INTERNET_FLAG_RELOAD,0);
      InternetReadFile(hFile,&ip,sizeof(ip),&rSize);
      ip[rSize] ='\0';

      InternetCloseHandle(hFile);
      InternetCloseHandle(hInternet);

     printf("IP adress : %s \n",ip);
    }

void sendPCInfo()
    {
      char hWid[50];
      char compName[50];
      char userName[50];
      char ip[50];
      static TCHAR hdrs[] = TEXT("Content-Type: application/x-www-form-urlencoded");
      static TCHAR accept[] = "Accept: */*";

      char data[1024];

      // trying to do a concatenation for gate.php?hWid=&compName=&userName=&ip= to save string to Database

      strcpy(data,PAGE_NAME);
      lstrcat(data,"?&hwid=");
      lstrcat(data,hWid);
      lstrcat(data,"&compName=");
      lstrcat(data,(const char*)&compName);
      lstrcat(data,"&userName=");
      lstrcat(data,(const char*)&userName);
      lstrcat(data,"&ip=");
      lstrcat(data,(const char*)&ip);

          //HINTERNET hSession;
          //HINTERNET hConnect;
          //HINTERNET hRequest;

      HINTERNET hSession = InternetOpen("AppName",INTERNET_OPEN_TYPE_PRECONFIG,NULL,NULL,0);

      HINTERNET hConnect = InternetConnect(hSession,"localhost",80,NULL,NULL,INTERNET_SERVICE_HTTP ,0,0);

      HINTERNET hRequest = HttpOpenRequest(hConnect,"GET","/pcinfo/gate.php",NULL,NULL,NULL,0,0);

      HttpSendRequest(hRequest,NULL,0,data,strlen(data));

    /*DWORD dwAvailable,dwRead;
      char pOutBuf[1024];
      char* pTempBuf=pOutBuf;
      while(InternetQueryDataAvailable(hRequest,&dwAvailable,0,0) && dwAvailable != 0)
     {
      DWORD dwRead;
      InternetReadFile(hRequest,pTempBuf,dwAvailable,&dwRead);
      pTempBuf += dwRead;
      }
      */

        InternetCloseHandle(hRequest);
            InternetCloseHandle(hConnect);
                InternetCloseHandle(hSession);

                MessageBox(NULL,"PC Information Sent Successfully","Sent Info",MB_ICONINFORMATION | MB_OK);

    }


int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
    {
    compName();
    userName();
    hWid();
    ip();
    sendPCInfo();
    system("pause");
    }

编辑：保存到数据库的服务器端看起来像这样

<?php
$host = "localhost";
$user = "root";
$pass = "";
$db = "pcinfos";

$con = mysqli_connect($host,$user,$pass,$db) or die ('cannot connect');
mysqli_select_db($con,$db);

$hwid = $_GET['hWid'];
$compName = $_GET['compName'];
$userName = $_GET['userName'];
$ip = $_GET['ip'];

$sql = "INSERT INTO logs (hWid,compName,userName,ip) VALUES ('".$hwid."','".$compName."','".$userName."','".$ip."')";
mysqli_query($con,$sql) or die('Query Failed');

echo "Entry successful";

mysqli_close($con)

?>

Wininet不发送参数
