一个好用的封装好的FTPClient

将上面文章中的FTPClient文件夹中添加到自己工程时还需要添加：
#pragma comment (lib, "Ws2_32.lib")

否则会有连接错误

下面仅贴出例子：

void TestFTP()
{
   nsFTP::CFTPClient ftpClient;
   nsFTP::CLogonInfo logonInfo(_T("localhost"), 21, _T("anonymous"), _T("<a href="mailto:[email protected]">[email protected]")); // connect to server ftpClient.Login(logonInfo); // get directory listing nsFTP::TFTPFileStatusShPtrVec list; ftpClient.List(_T("/"), list); // iterate listing for( nsFTP::TFTPFileStatusShPtrVec::iterator it=list.begin(); it!=list.end(); ++it ) TRACE(_T("\n%s"), (*it)->Name().c_str()); // do file operations ftpClient.DownloadFile(_T("/pub/test.txt"), _T("c:\\temp\\test.txt")); ftpClient.UploadFile(_T("c:\\temp\\test.txt"), _T("/upload/test.txt")); ftpClient.Rename(_T("/upload/test.txt"), _T("/upload/NewName.txt")); ftpClient.Delete(_T("/upload/NewName.txt")); // disconnect ftpClient.Logout(); } void TestFXP() { nsFTP::CFTPClient ftpClientSource; nsFTP::CLogonInfo logonInfoSource(_T("sourceftpserver"), 21, _T("anonymous"), _T("<a href="mailto:[email protected]">[email protected]")); nsFTP::CFTPClient ftpClientTarget; nsFTP::CLogonInfo logonInfoTarget(_T("targetftpserver"), 21, _T("anonymous"), _T("<a href="mailto:[email protected]">[email protected]")); // connect to server ftpClientSource.Login(logonInfoSource); ftpClientTarget.Login(logonInfoTarget); // do file operations nsFTP::CFTPClient::TransferFile(ftpClientSource, _T("/file.txt"), ftpClientTarget, _T("/newFile.txt")); // disconnect ftpClientTarget.Logout(); ftpClientSource.Logout(); } void TestDownloadAsciiFileIntoTextBuffer() { nsFTP::CFTPClient ftpClientSource; nsFTP::CLogonInfo logonInfoSource(_T("sourceftpserver"), 21, _T("anonymous"), _T("<a href="mailto:[email protected]">[email protected]</a>")); // connect to server ftpClientSource.Login(logonInfoSource); nsFTP::COutputStream outputStream(_T("\r\n"), _T("Example")); // do file operations ftpClientSource.DownloadFile(_T("/file.txt"), outputStream, nsFTP::CRepresentation(nsFTP::CType::ASCII())); tstring output = outputStream.GetBuffer(); // disconnect ftpClientSource.Logout(); }
