我想模仿著名的linux rsync命令的行为,如果未在目录末尾指定"/"并复制所有内容,则它将从" test"复制整个目录在"/"存在时"测试/"内部。我本地的"测试"文件夹是这样的结构:
test
.
├── fileA.txt
├── fileB.txt
├── test1
│ └── test3
│ └── file3.txt
└── test2
└── file2.txt
将整个本地测试文件夹复制到rsync中的远程服务器:
rsync -avzP test username@remotehost:/home/
在遥控主机的主目录内将是
home
.
|__ test
├── fileA.txt
├── fileB.txt
├── test1
│ └── test3
│ └── file3.txt
└── test2
└── file2.txt
示例
复制本地"测试"文件夹中的所有内容不包括本身:
rsync -avzP test/ username@remotehost:/home/
主目录的结构是:
home/
.
├── fileA.txt
├── fileB.txt
├── test1
│ └── test3
│ └── file3.txt
└── test2
└── file2.txt
示例B
我没有工作的代码例如B。我考虑过分开路径并摆脱"测试",然后复制其中的所有内容,但它只会使我进入无尽的嵌套,以获取循环。另一个想法是使用os.listdir。如果是目录,请再次列出目录并复制该目录中的内容。这仍然是循环的另一个无尽的。上面的树结构是一个过度简化的例子,但是在现实生活中,我们都知道目录可能是5个级别。如何实现示例B?
def put (self, localpath, remotepath):
sftp = self.ssh.open_sftp ()
# Create remote directory if it doesn't exist
try:
sftp.stat (remotepath)
except FileNotFoundError:
sftp.mkdir (remotepath)
if os.path.isfile (localpath):
# Obtain file name from local path & append to remote path
path = os.path.split (localpath) # Returns a tuple (directory, filename)
remote_filename = os.path.join (remotepath, path [1])
print (' Copying %s' % remote_filename)
sftp.put (localpath, remote_filename)
elif os.path.isdir (localpath):
p = os.path.join (remotepath, localpath)
try:
sftp.stat (p)
except FileNotFoundError:
sftp.mkdir (p)
for dirpath, dirnames, filenames in os.walk (localpath):
# Traverse into each child directory and create sub directory if it doesn't exist
if dirnames:
for dirname in dirnames:
subdir = os.path.join (dirpath, dirname)
try:
sftp.stat (subdir)
except FileNotFoundError:
sftp.mkdir (subdir)
for filename in filenames:
local_filename = os.path.join (dirpath, filename)
remote_filename = os.path.join (remotepath, local_filename)
sftp.put (local_filename, remote_filename)
我弄清楚了。这不是最漂亮的,而是功能。如果有人有更好,更清洁和更多的Pythonic方法,请分享。
