Python completes the file transfer between 2 linux through the program.

The application scenario is to transfer files on one server to another server through a program.
Manually type the linux command
scp: remote copy (local --> remote server)
scp file name username@IP address: absolute path

# -- coding: utf-8 --
import paramiko

def remote_scp(host_ip,remote_path,local_path,username,password):
    t = paramiko.Transport((host_ip,22))
    t.connect(username=username, password=password) # 登录远程服务器
    sftp = paramiko.SFTPClient.from_transport(t)# sftp传输协议
    src = remote_path
    des = local_path
    sftp.get(src,des)
    t.close()

host_ip='xxx.xx.xx.xx' #不需要带端口
username='xxx'
password='xxx'
remote_path=r'/root/xxx/xx.html'#远程文件名的路径
local_path=r'./xx.html'#必须要带文件名，不带会出错。
remote_scp(host_ip,remote_path,local_path,username,password)
