ftp客户端，Qt5，mac OS
自己基于Tcp实现的ftp协议

登录：账户/匿名登录

功能：目录浏览、下载、上传、删除
截图：

后面修改了下，增加了tcp协议的简单交互模型，支持应用层协议简单的指令交互，已尝试SMTP、POP、imap可用

复制代码

/*以下是SMTP连接qq邮箱发邮件的过程*/
// SMTP.qq.com port:21
/* write(socket,"HELO SMTP.qq.com\r\n",return2textEdit); //消息确认
write(socket,"AUTH LOGIN\r\n",return2textEdit); //消息确认
write(socket,"xxxxxx==\r\n",return2textEdit); //消息确认
write(socket,"xxxxxx==\r\n",return2textEdit); //消息确认账户密码都使用了base64转换
