Python paramiko SFTP protocol upload and download files

.description _

The business has a delivery process, and the manual operation is too cumbersome, so I want to implement it through code. The first problem is to interact with the linux server on Windows, upload and download files using the SFTP protocol (SSL-encrypted FTP protocol, similar to HTTPS. PS: Personal understanding!)

Install

pip install paramiko

import paramiko

host = "123.123.123.123"
port = 54321
user = "XXX"
password = "XXXX"


# 第一种登录服务器的方法
def login_sftp1():
    try:
        # 建立连接管道
        t = paramiko.Transport((host,port))# 注意是双层括号，之前搞了好久。
        # 建立连接
        t.connect(username=user,password=password)
        # 实例化一个clint对象，并通过ssh transport操作文件
        sftp = paramiko.SFTPClient.from_transport(t)
    except Exception as e:
        print (e)
    # 查看目标服务器的当前文件夹的目录文件,默认参数path='.'。
    print sftp.listdir()
    t.close()
    sftp.close()

# 第二种登录方法
def login_sftp2()
    try:
        sc= paramiko.SSHClient()
        sc.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        sc.connect(host,port,user,password)
        # 获取操作文件的实例也有两种方式 
        sftp = paramiko.SFTPClient.from_transport(sc.get_transport())#①
        -------------------------------------------------------------------
        sftp = ssh.open_sftp()#②
    except Exception as e:
        print (e)
    print sftp.listdir()
    sc.close()
    sftp.close()

# 文件上传
sftp.put(localpath,remotepath)

#文件下载
sftp.get(remotepath,localpath)
