如何使用 ansible 'expect' 模块进行多个不同的响应？

Question

我在这里尝试测试我的 bash 脚本，它提示了四次。

#!/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，我编写了下面的代码，它运行良好

- 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

- 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

我也试过空白 '' 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 文档，但它们只显示了非常简单的示例和解释。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。

Answer 1

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

因此：

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

应该改为：

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

祝你好运！
