Python中paramiko模块的基础操作与排错问题

第Python中paramiko模块的基础操作与排错问题cmdList=["cd/home","ls"]

print(execMultiCmd("28","root","root",cmdList))

4.SFTPClient下载文件

方法封装：

defdown_file(host,user,psw,local_file,remote_file,port=22):

withparamiko.Transport((host,port))astransport:

#连接服务

transport.connect(username=user,password=psw)

#获取SFTP示例

sftp=paramiko.SFTPClient.from_transport(transport)

#下载

sftp.get(remote_file,local_file)

transport.close()

问题：（错误)

if__name__=='__main__':

down_file(my_linux.host,my_linux.user,my_linux.psw,"D:\\ssh_download","/home/test.txt")

Traceback(mostrecentcalllast):

File"D:\MyCode2\py-1\ssh\download.py",line17,inmodule

down_file("28","root","root","D:\\ssh_download","/home/test.txt")

File"D:\MyCode2\py-1\ssh\download.py",line11,indown_file

sftp.get(remote_file,local_file)

File"D:\MyCode2\py-1\venv\lib\site-packages\paramiko\sftp_client.py",line810,inget

withopen(localpath,"wb")asfl:

PermissionError:[Errno13]Permissiondenied:'D:\\ssh_download'

正确使用

要指定下载的文件名，不能只是一个目录

if__name__=='__main__':

down_file(my_linux.host,my_linux.user,my_linux.psw,"D:\\ssh_download\\test.txt","/home/test.txt")

5.上传文件

defupload_file(host,user,psw,local_file,remote_file,port=22):

withparamiko.Transport((host,port))astransport:

#连接服务

transport.connect(username=user,password=psw)

#获取SFTP示例

sftp=paramiko.SFTPClient.from_transport(transport)

sftp.put(local_file,remote_file)

transport.close()

测试同下载，特别要注意路径问题。如

if__name__=='__main__':

upload_file(my_linux.host,my_linux.user,my_linux.psw,"D:\\ssh_down
