在OSX上使用python将文件复制到网络路径或驱动器 [英] Copy files to network path or drive using python on OSX

问题描述

我有一个类似的问题，例如这里的问题，但我需要在OSX上使用它.

I have a similar question like the one asked here but I need it to work on OSX.

如何使用Python将文件复制到网络路径或驱动器

所以我想将文件保存在SMB网络共享上.能做到吗?

So i want to save a file on a SMB network share. Can this be done?

谢谢！

推荐答案

是的，可以做到.首先，通过从Python调用以下命令，将SMB网络共享安装到本地文件系统:

Yes, it can be done. First, mount your SMB network share to the local filesystem by calling a command like this from Python:

mount -t smbfs //user@server/sharename share

(您可以使用subprocess模块执行此操作). share是将SMB网络共享安装到的目录的名称，我想它必须是用户可写的.之后，您可以使用shutil.copyfile复制文件.最后，您必须卸载SMB网络共享:

(You can do it using the subprocess module). share is the name of the directory where the SMB network share will be mounted to, and I guess it has to be writable by the user. After that, you can copy the file using shutil.copyfile. Finally, you have to un-mount the SMB network share:

umount share

最好用Python创建一个上下文管理器，该上下文管理器负责挂载和卸载:

Probably it's the best to create a context manager in Python that takes care of mounting and unmounting:

from contextlib import contextmanager
import os
import shutil
import subprocess

@contextmanager
def mounted(remote_dir, local_dir):
    local_dir = os.path.abspath(local_dir)
    retcode = subprocess.call(["/sbin/mount", "-t", "smbfs", remote_dir, local_dir])
    if retcode != 0:
        raise OSError("mount operation failed")
    try:
        yield
    finally:
        retcode = subprocess.call(["/sbin/umount", local_dir])
        if retcode != 0:
            raise OSError("umount operation failed")

with mounted(remote_dir, local_dir):
    shutil.copy(file_to_be_copied, local_dir)

上面的代码段未经测试，但应该可以正常使用(除了我没有注意到的语法错误).还要注意，mounted与我在其他答案中发布的network_share_auth上下文管理器非常相似，因此您也可以通过使用platform模块检查所使用的平台，然后调用适当的命令来将两者结合

The above code snippet is not tested, but it should work in general (apart from syntax errors that I did not notice). Also note that mounted is very similar to the network_share_auth context manager I posted in my other answer, so you might as well combine the two by checking what platform you are on using the platform module and then calling the appropriate commands.
