如何强制执行＆＃34;是＆＃34;或＆＃34;不＆＃34;在定义/anything？
例如。有了这本剧本：
res.redirect('/'+theSubject); // or req.param.subject, whatever may be your requirement
// as I'm not aware of your application requirements.最后一项任务将失败，因为vars_promp是一个值为＃34;是＆＃34;的字符串。当指定＆＃34; true＆＃34;时，它不会被转换为布尔值。 （ANSWER2）。
使用---
- name: variable tests
hosts: local
gather_facts: false
vars:
answer1: yes
vars_prompt:
- name: "answer2"
prompt: "Reply true"
private: no
- name: "answer3"
prompt: "Reply yes"
private: no
tasks:
- debug: msg="answer1 is true"
when: answer1
- debug: msg="answer2 is true"
when: answer2
- debug: msg="answer3 is true"
when: answer3
时，转换为true或false布尔值已经是行为（如在answer1中）。
