如果你需要在局域网分享文件,可以使用QQ微信等办公软件挺方便的,但是如果是大文件,比如说好几G的,先不说速度慢,由于限制,还不一定能发给别人
但如果你的电脑上安装了python(没有的话也可以自己安装一个,占用资源很小),我们可以使用它自带的http模块运行一个http服务,这样局域网内的设备都能通过浏览器去访问和下载文件了
由于走的是局域网路线,所以传输速度基本上取决于你的路由器或交换机的速度
打开cmd或者powershell,使用python命令启动http.server模块
python -m http.server 端口 # 端口可以不写,默认是8000
它提示成功之后我们就可以在浏览器根据你的ip端口进行访问了,此处ip是局域网ip,可以通过在cmd输入ipconfig查看你本机局域网ip
上面的步骤是先进入你要分享的文件夹然后再运行http服务,而且还需要手动查看本机ip,我们完全可以写一个代码,把这些步骤全部整合在一起,把py文件的默认打开方式改为python,即把封装好的脚本复制到你要分享的文件夹,然后双击运行即可
