博主分享了一篇教程，利用MicroPython实现了一个简单的FTP服务器，仅需一个Python文件。教程详细介绍了代码实现过程，包括连接WiFi、处理FTP命令如LIST、RETR、STOR等。注意，最新版的EDGE和Chrome浏览器已不支持FTP。

好久没出教程了，因为我秉承只上干货的原则，只发有用的干货（偶尔也夹带一些自己的碎碎念），然后就是能上代码直接粘贴出来，让大家来了就不白来，不要随便浪费别人的时间。
不废话了，这次用micropython做了一个ftp的服务端，github上面找来的，很精简，就一个py文件，需要的拿走，直接贴代码。

else:

        pass
    print('WIFI connected first')
print(wlan.ifconfig()[0])    #建立WIFI连接的方法自己随便弄，这里给个参考，ftp的地址就是打印出来的，ifconfig()的第一项
