如何将 ansible 'expect' 模块用于多个不同的响应? [英] How to use ansible 'expect' module for multiple different responses?

问题描述

在这里，我试图测试我的 bash 脚本，它提示了四次.

Here I am trying to test my bash script where it is prompting four times.

#!/bin/bash
date >/opt/prompt.txt
read -p "enter one: " one
echo $one
echo $one >>/opt/prompt.txt
read -p "enter two: " two
echo $two
echo $two >>/opt/prompt.txt
read -p "enter three: " three
echo $three
echo $three >>/opt/prompt.txt
read -p "enter password: " password
echo $password
echo $password >>/opt/prompt.txt

对于这个脚本，我写了下面的代码，它运行良好

for this script I wrote the code below, and it is working fine

- hosts: "{{ hosts }}"
  tasks:
  - name: Test Script
    expect:
      command: sc.sh
      responses:
        enter one: 'one'
        enter two: 'two'
        enter three: 'three'
        enter password: 'pass'
      echo: yes

但是如果我对 mysql_secure_installation 命令做同样的事情，它就不起作用

But if I am doing the same for mysql_secure_installation command it not working

- hosts: "{{ hosts }}"
  tasks:
  - name: mysql_secure_installation Command Test
    expect:
      command: mysql_secure_installation
      responses:
        'Enter current password for root (enter for none):': "\n"
        'Set root password? [Y/n]:': 'y'
        'New password:': '123456'
        'Re-enter new password:': '123456'
        'Remove anonymous users? [Y/n]:': 'y'
        'Disallow root login remotely? [Y/n]:': 'y'
        'Remove test database and access to it? [Y/n]:': 'y'
        'Reload privilege tables now? [Y/n]:': 'y'

      echo: yes

我也尝试了空白 '' 而不是 "\n" 作为第一个答案，但它也不起作用.我还访问了 Ansible expect doc 但它们只显示非常简单例子和解释.我也在尝试对多个不同的响应进行正则表达式匹配，但它也不起作用.
请不要推荐我使用Ansible的mysql模块，因为我在这里的目的是学习这个模块以备将来使用.

I have also tried blank '' instead of "\n" for the first answer but it is not working either. I also visited Ansible expect doc but they show only very simple example and explanation. I am also trying regex match for multiple different responses but it is also not working.
Please do not recommend me to use mysql module of Ansible, because here my purpose is to learn this module for future use.

推荐答案

原因是问题被解释为正则表达式.因此，您必须对正则表达式中具有特殊含义的字符进行转义，例如 -()[]\?*.等等.

The reason is that the questions are interpreted as regexps. Hence you must escape characters with a special meaning in regular expressions, such as -()[]\?*. et cetara.

因此:

'Enter current password for root (enter for none):'

应该是:

'Enter current password for root \(enter for none\):'

祝你好运！
