Python实现远程文件传输

Python实现远程文件传输(socket) (paramiko)

环境

Python 3.7.4
socket
paramiko==2.7.1
CentOS Linux release 8.1.1911 (Core)

实现代码

为远程计算机主机名（云服务器公网IP），为端口号，云服务器默认为22，使用其他端口需要到安全组配置放开端口，为登录用户名，阿里云默认为root，为登录云服务器的密钥文件路径

import os
import paramiko

class SCPTransmitter():
	```
		Description:
			upload local files to remote server or download remote file to local dirctory by Secure Copy and SSH File Transfer Protocol
		Attributes:
			None
	```
    def __init__(self):

        self.hostname = ''
        self.port = <port>
        self.username = <user name>

        self.public_key = paramiko.RSAKey.from_private_key_file('')
        self.scp = paramiko.Transport(self.hostname, self.port)
        self.scp.connect(username=self.username, pkey=self.public_key)
        self.sftp = paramiko.SFTPClient.from_transport(self.scp)

	```
		Description:
			download remote files from remote server
		Args:
			remote_path:
				remote dirctory of files wanna download
			local_path:
				local path to save files
		Returns:
			None
	```	

    def download(self, remote_path, local_path):
        try:
            remote_files = self.sftp.listdir(remote_path)
            for file in remote_files:
                local_file = local_path + file
                print(local_file)
                remote_file = remote_path + file
                print(remote_file)
                self.sftp.get(remote_file, local_file)
            print("Successfully")
        except IOError:
            return ("remote_path or local_path is not exist")

	```

    def upload(self, remote_path, local_path):

            print("Successfully")
        except IOError:
            return ("remote_path or local_path is not exist")



if __name__ == "__main__":

    remote_path = '/home/remote/'    
    local_path = './res/remote/'
    transmitter = SCPTransmitter()
    transmitter.upload(remote_path, local_path)
