Question

对于我的项目，我需要能够使用脚本将程序（HTML）的输出复制到我的服务器，因此只需启动脚本即可完成，无需进一步处理。只应对内容已更改的文件进行上传，因为在我的程序中新发布后，日期总是会更改。

我在网上发现了一个能够通过一些细微的改动做我想做的事情的脚本。现在，当我在计算机上的两个文件夹之间发布时，它可以工作，但我应该可以用sFTP或SSH连接替换我的目的地......

您可以使用fabrics put命令轻松sftp文件。

from fabric.api import *
env.hosts = [<hosts>]
with cd('/tmp'):
    put('/path/to/local/test.txt', 'files')

脚本将文件从本地计算机同步到外部主机（sftp或ssh）
