请耐心等待。它只是一个星期,我开始使用python。继承人问题:我想连接到FTP服务器。假定我的ftp和本地目录上的文件结构是相同的。我想让我的python程序执行以下操作:制作一个很好的ftp检查python程序的麻烦
1>在运行程序时,它应该上传所有不在服务器上但位于本地 上的文件(只上传缺失的文件 - 不能全部替换)。 说,我添加一个新的目录或一个新的文件,它应该照原样上载到服务器上。 2>然后它应该检查本地和服务器上这两个文件的修改时间,并通知哪些是最新的。
现在,我已经做了两个方案:
将从本地上传的所有文件服务器上,因为它是1>一个程序。我宁愿它检查丢失的文件,然后仅卸载丢失的文件文件夹。 NOt全部取代。 2>第二个程序将使用os.walk列出来自本地的所有文件,并且它将上传服务器上的所有文件而不创建正确的目录结构。 所有被复制到服务器的根目录。然后它还检查修改的时间。
我现在正在尝试将这两个模块加入到一个完美的模型中,以满足我的所有需求。任何能够真正查看这些代码并尝试将它们加入我想要做的事情的人都是完美的。对不起,这样的痛苦! PS:我可能没有做任何事情的简单方法!

谢谢你。我一定会看看它。此外,上面的代码是我自己的,你认为我可以真正使用它们同步程序。所有需要的功能都只是我无法将它们加入到其中。 – Jino 2013-02-20 07:31:56
