Python scp复制文件，文件名中有空格

Question

我正在尝试用SCP复制本地网络中的文件。它在没有空格的文件名中工作得很好，但在使用时会崩溃。我试着把“”替换成“\”作为这个例子，但它不起作用。下面是我的代码：

def connection(locals):
         a = (int(re.search(br'(\d+)%$', locals['child'].after).group(1)))
         print a
         perc = (Decimal(a)/100)
         print (type(perc)), perc
         while gtk.events_pending():
             gtk.main_iteration()
         FileCopy.pbar.set_text("Copy of the file in the Pi...   " + str(a) + "%")
         while gtk.events_pending():
             gtk.main_iteration()
         FileCopy.pbar.set_fraction(perc)

file_pc = "/home/guillaume/folder/a very large name of file with space .smthg"
file_pi = "pi@192.168.X.X:/home/pi/folder/a very large name of file with space .smthg"

if " " in file_pc:
   file_pc = fichier_pc.replace(" ", '\\\ ')   # tried '\\ ' or '\ '
   file_pi = fichier_pi.replace(" ", '\\\ ')   # but no way
else:
   pass
command = "scp %s %s" % tuple(map(pipes.quote, [file_pc, file_pi]))
pexpect.run(command, events={r'\d+%': connection}) # this command is using to get the %

如何修复此问题？谢谢

您可以保持本地文件file_pc原样(pipes.quote将转义空格）。应更改远程文件：

import pipes

file_pi = 'pi@192.168.X.X:/home/pi/folder/file with space.smth'
host, colon, path = file_pi.partition(':')
assert colon
file_pi = host + colon + pipes.quote(path)

例如，user@host:/path/with space应更改为user@host:'/path/with space'
