Python：Telnet 密码未通过使用 pexpect 的脚本获取

Question

我在使用 pexpect 运行我的 telnet 脚本时遇到问题。问题是它只从脚本中获取用户名而不是密码。它获取密码的值但输入的值不一样。在我的脚本下面提到，

import pexpect
import sys,time
ipaddr = "192.168.100.85"
username = "usr"
password = "Pass@123"
telconn = pexpect.spawn("telnet " + ipaddr)
telconn.expect(":")
telconn.logfile=sys.stdout
time.sleep(15)
telconn.sendline(username + "\r")
telconn.expect(":")
telconn.sendline(password + "\r")
time.sleep(30)
telconn.expect(">")
print "Authentication Sucesss"

这个的输出，

Trying 192.168.100.85...
Connected to 192.168.100.85.
Escape character is '^]'.
Welcome to Microsoft Telnet Service 


login: usr

password: Pass@123

The operation completed successfully.

Login Failed

我找到了解决方案，

import pexpect
import time,sys
telconn = pexpect.spawn('telnet 192.168.100.85')
time.sleep(20)
telconn.logfile = sys.stdout
telconn.expect(":")
time.sleep(20)
telconn.send("usr" + "\r")
telconn.expect(":")
telconn.send("Pass@123" + "\r")
telconn.send("\r\n")
time.sleep(20)
telconn.expect(">")

这对我有用
