在自动化过程中无法在Expect Shell脚本中建立主机的真实性时如何忽略或通过“是" [英] How to ignore or Pass 'Yes' when The authenticity of host can't be established in Expect Shell script during Automation

问题描述

当在我的Expect Shell脚本的执行过程中出现以下语句时，我想自动提供是"还是忽略它并以安全的方式继续?

I want to Provide 'Yes' automatically or Ignore it and proceed in a SECURE way, when the below statement comes during execution of my Expect Shell script?.

#!/usr/bin/expect
spawn ssh $user@$host

无法确定主机"abcdef(10.566.1.98)"的真实性. RSA密钥指纹为jk:94:ba:93:0b:eb​​:ff:df:ea:gh:hj:23:3c:hj:9c:be. 您确定要继续连接(是/否)吗?

The authenticity of host 'abcdef (10.566.1.98)' can't be established. RSA key fingerprint is jk:94:ba:93:0b:eb:ff:df:ea:gh:hj:23:3c:hj:9c:be. Are you sure you want to continue connecting (yes/no)?

推荐答案

在这种情况下使用exp_continue.

#!/usr/bin/expect 
set prompt "#|>|\\\$"
spawn ssh dinesh@myhost
expect {
        #If 'expect' sees '(yes/no )', then it will send 'yes'
        #and continue the 'expect' loop
        "(yes/no)" { send "yes\r";exp_continue}
        #If 'password' seen first, then proceed as such.
        "password"
}
send "root\r"
expect -re $prompt
