Python制作~局域网大文件分享传输工具~源码

xiaomingtt

由于单位不让用优盘、禁止用飞秋、也不准使共享，禁用FTP，也禁止搭建网站，且目前局域网内用的IM不支持1G以上文件传输，于是在找适合内网的大文件传输方法。开始搭建网盘，但上传一次、下载一次，效率还是有点低。后来用Everything的HTTP服务器，结果把整个硬盘都分享了，太不安全。于是就自己做了这个简单的文件分享工具。（GUI是Chat GPT写的，部分功能代码是网上Copy的。）

HTTP分享，利用Flask搭建了一个Web服务器，选择要分享的文件启动后，将生成的链接发给对方，对方就可以通过浏览器下载。
FTP分享用pyftpdlib搭建了一个FTP服务器，同样生成链接后，对方可以通过一些浏览器或FTP客户端下载，也可以通过程序提供的工具下载文件。

楼主，你可以了解下localsend，那个开源软件已经支持各大主流系统平台，接收还不需要客户端，使用浏览器下载就行

liuwei19870301

给你个建议，加入SFTP传输协议，有的地方ftp不稳定，而且还会被封锁！

笑太阳

单一功能，还不错，支持动手能力强的。但是，有 HFS  CHFS DUFS 这些比较通用。

最大有多大？10G支持吗

没问题啊！30多G我都传了

楼主python学的溜

minghan0313

支持开源。

上学的时候用过一款工具叫飞秋，也是不错。

和局域网的smb传输，速度比较如何

Kls673M

你这个下载要开软件下载？ 如果局域网路由器不限制用系统的共享不就可以了吗？
不过你说用Flask搭web可分享链接下载这个可以，不过生成的链接是什么样子？
