我正在尝试从远程路径获取文件到我的本地目录.当我执行代码时，出现错误.如下所述.

I am trying to get files from remote path to my local dir. When i am executing the code i am getting an error. as described below.

import paramiko import SSHLibrary from stat import S_ISDIR server, username, password = ('Remote ID', 'root', 'root') ssh = paramiko.SSHClient() paramiko.util.log_to_file("ssh.log") ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(server, username=username, password=password) ssh_stdin, ssh_stdout, ssh_stderr = ssh.exec_command('ls') print "output", ssh_stdout.read() #Reading output of the executed command error = ssh_stderr.read() #Transfering files to and from the remote machine sftp = ssh.open_sftp() print sftp.getcwd() print sftp.get_channel() print sftp.listdir("/home") sftp.get("/home","C:\\Users\\ShareM\\Desktop") #---> facing problem here sftp.close() ssh.close()

错误:-

Traceback (most recent call last): File "C:\Users\ShareM\Desktop\Automotive\devlopment\sshtesting\src\sshtest.py", line 36, in <module> sftp.get("/home","C:\\Users\\ShareM\\Desktop") File "build\bdist.win32\egg\paramiko\sftp_client.py", line 637, in get IOError: [Errno 13] Permission denied: 'C:\\Users\\ShareM\\Desktop'

需要帮助.

推荐答案

问题在于 sftp.get() 旨在传输单个文件而不是目录.因此，要下载整个目录，您应该获取其中的文件列表并单独下载:

The problem is that sftp.get() is intended to transfer a single file not a directory. So to download entire directory you should get list of files in it and download them separately:

def download_dir(remote_dir, local_dir): import os os.path.exists(local_dir) or os.makedirs(local_dir) dir_items = sftp.listdir_attr(remote_dir) for item in dir_items: # assuming the local system is Windows and the remote system is Linux # os.path.join won't help here, so construct remote_path manually remote_path = remote_dir + '/' + item.filename local_path = os.path.join(local_dir, item.filename) if S_ISDIR(item.st_mode): download_dir(remote_path, local_path) else: sftp.get(remote_path, local_path) download_dir("/home","C:\\Users\\ShareM\\Desktop")
