试图用 C++ 包装这个简短的例子。(自从我这样做以来已经有一段时间了)。
int main(int argc, char* argv[])
{
//Objects
CFtpConnection* pConnect = NULL; //A pointer to a CFtpConnection object
ftpClient UploadExe; //ftpClient object
pConnect = UploadExe.Connect();
UploadExe.GetFiles(pConnect);
system("PAUSE");
return 0;
}
。H -
class ftpClient
{
public:
ftpClient();
CFtpConnection* Connect();
void GetFiles(CFtpConnection* pConnect);
};
.cpp -
//constructor
ftpClient::ftpClient()
{
}
CFtpConnection* ftpClient::Connect()
{
// create a session object to initialize WININET library
// Default parameters mean the access method in the registry
// (that is, set by the "Internet" icon in the Control Panel)
// will be used.
CInternetSession sess(_T("FTP"));
CFtpConnection* pConnect = NULL;
try
{
// Request a connection to ftp.microsoft.com. Default
// parameters mean that we'll try with username = ANONYMOUS
// and password set to the machine name @ domain name
pConnect = sess.GetFtpConnection("localhost", "sysadmin", "ftp", 21, FALSE );
}
catch (CInternetException* pEx)
{
TCHAR sz[1024];
pEx->GetErrorMessage(sz, 1024);
printf("ERROR! %s\n", sz);
pEx->Delete();
}
// if the connection is open, close it MOVE INTO CLOSE FUNCTION
// if (pConnect != NULL)
// {
// pConnect->Close();
// delete pConnect;
// }
return pConnect;
}
void ftpClient::GetFiles(CFtpConnection* pConnect)
{
// use a file find object to enumerate files
CFtpFileFind finder(pConnect);
if (pConnect != NULL)
{
printf("ftpClient::GetFiles - pConnect NOT NULL");
}
// start looping
BOOL bWorking = finder.FindFile("*"); //<---ASSERT ERROR
// while (bWorking)
// {
// bWorking = finder.FindNextFile();
// printf("%s\n", (LPCTSTR) finder.GetFileURL());
// }
}
所以基本上将连接和文件操作分为两个功能。findFile() 函数正在抛出断言。(进入 findFile() 并且它具体位于 inet.cpp 中的第一个 ASSERT_VALID(m_pConnection)。)
我通过 arround CFtpConnection* pConnect 的方式如何?
编辑- 看起来 CObject vfptr 在 GetFiles() 函数中被覆盖(0X00000000)。
任何帮助表示赞赏。谢谢。
