//退出FTP服务器 int CFTP::ftp_quit() { sprintf_s(m_cmd,"QUIT "); int err = ftp_sendcmd(m_cmd,m_resp,sizeof(m_resp)); if(err) return -1; //得到返回码 int code = get_state_code(m_resp); //221 Goodbye. if(code != 221) return -1; return 0; }
退出FTP服务器通过发送命令QUIT实现。
//进入指定的FTP目录 int CFTP::ftp_cd( const char* dir ) { sprintf_s(m_cmd,"CWD %s ",dir); int err = ftp_sendcmd(m_cmd,m_resp,sizeof(m_resp)); if(err) return -1; //得到返回码 int code = get_state_code(m_resp); //250 CWD command successful. /* 550-The system cannot find the file specified. Win32 error: The system cannot find the file specified. Error details: File system returned an error. 550 End */ if(code != 250) return -1; return 0; }
通过命令CWD可以进入指定的FTP目录。
//返回上级FTP目录 int CFTP::ftp_cdup() { sprintf_s(m_cmd,"CDUP "); int err = ftp_sendcmd(m_cmd,m_resp,sizeof(m_resp)); if(err) return -1; //得到返回码 int code = get_state_code(m_resp); //250 CDUP command successful. /* 550-The system cannot find the file specified. Win32 error: The system cannot find the file specified. Error details: File system returned an error. 550 End */ if(code != 250) return -1; return 0; }
返回上级目录通过命令CDUP实现。
