ftp>四 代码
from __future__ import unicode_literals # 使用unicode编码
import pexpect
import sys
child = pexpect.spawnu('ftp ftp.scene.org') # 运行ftp命令
child.expect('(?i)name .*: ') #（？i）表示后面的字符串正则匹配忽略大小写
#child.expect('(ftp.scene.org:root): ')
child.sendline('anonymous') # 输入ftp账号信息
child.expect('(?i)password') # 匹配密码输入提示
child.sendline('[email protected]') # 输入ftp密码，输入一个邮箱地址
child.expect('ftp> ')
child.sendline('bin') # 启用二进制传输模式
child.expect('ftp> ')
child.sendline('get welcome.msg') # 下载welcome.msg文件
child.expect('ftp> ')
sys.stdout.write (child.before) # 输出匹配“ftp> ”之前的输入与输出
print("Escape character is '^]'.\n")
sys.stdout.write (child.after)
sys.stdout.flush()
# 调用 interact（）让出控制权，用户可以继续当前的会话手工控制子程序，默认输入“^]”字符跳出
child.interact() # Escape character defaults to ^]
child.sendline('bye')
child.close()五 结果
