python脚本实现scp上传下载功能

方法一：

python使用paramiko实现远程拷贝文件的方法

首先是安装paramiko库(其实现了SSH2安全协议)，ubuntu下可直接通过源安装:

pip instal paramiko

方法二：

python使用pexpect实现远程拷贝文件的方法使用

import osimport sysimport pexpect

remoteFile = "test.jpg"localPath = "/home/"remote_password = "123456"try:    # 要执行的命令或者脚本   child = pexpect.spawn("scp root@192.168.1.100:/home/"+remoteFile+" "+localPath)        # 将日志指向标准输出   child.logfile = sys.stdout     # 执行命令后需要匹配的结果   child.expect("root@192.168.1.100's password:")    # 匹配成功后，发送命令   child.sendline(remote_password)        # 执行上条命令，需要等待很久才会得到结果的，需要使用while否则报pexpect.TIMEOUT异常   while 1:      index = child.expect(['.* result file generated.*',pexpect.EOF, pexpect.TIMEOUT])      if index == 0:            # 匹配到项后，跳出循环         break        elif index == 1:            # continue to wait          pass         elif index == 2:            # continue to wait          pass      child.sendline('exit')   child.sendcontrol('c')   child.interact()except OSError:   sys.exit(0)
