paramiko上的目录传输

Question

你如何使用paramiko传输完整的目录？我正在尝试使用:

sftp.put("/Folder1","/Folder2")

这给了我这个错误 -

Error : [Errno 21] Is a directory

Answer 1

您可以继承paramiko.SFTPClient并向其添加以下方法:

import paramiko
import os

class MySFTPClient(paramiko.SFTPClient):
    def put_dir(self, source, target):
        ''' Uploads the contents of the source directory to the target path. The
            target directory needs to exists. All subdirectories in source are 
            created under target.
        '''
        for item in os.listdir(source):
            if os.path.isfile(os.path.join(source, item)):
                self.put(os.path.join(source, item), '%s/%s' % (target, item))
            else:
                self.mkdir('%s/%s' % (target, item), ignore_existing=True)
                self.put_dir(os.path.join(source, item), '%s/%s' % (target, item))

    def mkdir(self, path, mode=511, ignore_existing=False):
        ''' Augments mkdir by adding an option to not fail if the folder exists  '''
        try:
            super(MySFTPClient, self).mkdir(path, mode)
        except IOError:
            if ignore_existing:
                pass
            else:
                raise

要使用它:

transport = paramiko.Transport((HOST, PORT))
transport.connect(username=USERNAME, password=PASSWORD)
sftp = MySFTPClient.from_transport(transport)
sftp.mkdir(target_path, ignore_existing=True)
sftp.put_dir(source_path, target_path)
sftp.close()

适合我做这样的事情，所有文件夹和文件都复制到远程服务器。

parent = os.path.expanduser("~")
for dirpath, dirnames, filenames in os.walk(parent):
    remote_path = os.path.join(remote_location, dirpath[len(parent)+1:])
        try:
            ftp.listdir(remote_path)
        except IOError:
            ftp.mkdir(remote_path)

        for filename in filenames:
            ftp.put(os.path.join(dirpath, filename), os.path.join(remote_path, filename))

这是我的代码：

import errno
import os
import stat

def download_files(sftp_client, remote_dir, local_dir):
    if not exists_remote(sftp_client, remote_dir):
        return

    if not os.path.exists(local_dir):
        os.mkdir(local_dir)

    for filename in sftp_client.listdir(remote_dir):
        if stat.S_ISDIR(sftp_client.stat(remote_dir + filename).st_mode):
            # uses '/' path delimiter for remote server
            download_files(sftp_client, remote_dir + filename + '/', os.path.join(local_dir, filename))
        else:
            if not os.path.isfile(os.path.join(local_dir, filename)):
                sftp_client.get(remote_dir + filename, os.path.join(local_dir, filename))


def exists_remote(sftp_client, path):
    try:
        sftp_client.stat(path)
    except IOError, e:
        if e.errno == errno.ENOENT:
            return False
        raise
    else:
        return True

Answer 4

你需要像在python本地一样(如果你没有使用shutils).

结合os.walk(),与sftp.mkdir()和sftp.put().您可能还想检查每个文件和目录,os.path.islink()具体取决于您是否要解析符号链接.

这一切都可以使用 paramiko 轻松完成。

以下代码的高级摘要是：
- 连接到 SFTP（步骤 1 到 3）
- 指定您的源文件夹和目标文件夹。（第 4 步）
- 将它们一一复制到您喜欢的任何位置（我已将它们发送到 /tmp/）。（第 5 步）

import paramiko

# 1 - Open a transport
host="your-host-name"
port = port_number
transport = paramiko.Transport((host, port))

# 2 - Auth
password="sftp_password"
username="sftp_username"
transport.connect(username = username, password = password)

# 3 - Go!

sftp = paramiko.SFTPClient.from_transport(transport)

# 4 - Specify your source and target folders.
source_folder="some/folder/path/on/sftp"
inbound_files=sftp.listdir(source_folder)

# 5 - Download all files from that path
for file in inbound_files :
    filepath = source_folder+file
    localpath = "/tmp/"+file
    sftp.get(filepath, localpath)
