2、*parameters);//方法调用int_tmain(intargc,TCHAR*argv[],TCHAR*envp[]){  intnRetCode=0;  //initializeMFCandprintanderroronfailure  if(!AfxWinInit(::GetModuleHandle(NULL),NULL,::GetCommandLine(),0))  {    //TODO:changeerrorcodetosuityourneeds    _tprintf(_T("FatalError:MFCinitializationfailed

3、n"));    return1;  }     request("reg.163.com","http://reg.163.com/CheckUser.jsp","test");  returnnRetCode;}//函数实现intrequest(char*hostname,char*api,char*parameters){  WSADATAWsaData;  WSAStartup(0x0101,&WsaData);  //初始化socket  structhostent*host_addr=gethostbyname(hostname);  if(host_a
