无法将属性与数字进行比较。错误：“‘AnsibleUnsafeText’和‘int’实例之间不支持”

- getent:
    database: passwd
- debug: 
    var: getent_passwd | dict2items | selectattr('value.1', '>=', 1000) | map(attribute='key') | list

输出是

TASK [debug] ******************************************************************************************************
fatal: [localhost]: FAILED! => {"msg": "Unexpected templating type error occurred on 
({{getent_passwd | dict2items | selectattr('value.1', '>=', 1000) | map(attribute='key') | list}}): 
'>=' not supported between instances of 'AnsibleUnsafeText' and 'int'"}

如何将“value.1”更改为整数？

Q: "我该如何改变value.1为整数？"

A: Use json_query https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#json-query-filter功能收件人号码 https://jmespath.org/specification.html#to-number。例如

    - debug:
        var: getent_passwd|
             dict2items|
             json_query('[?to_number(value[1]) >= `1000`].key')

Q: "我该如何改变1000到一个变量？"

A：替换也应该转换为数字。声明是一个好主意query分别地。例如

    - set_fact:
        myusers: "{{ getent_passwd|dict2items|json_query(query) }}"
      vars:
        myuid: 1000
        query: "[?to_number(value[1]) >= to_number('{{ myuid }}')].key"

Q: "如何在 json_query 函数中添加更多条件？喜欢selectattr('value.5', 'ne', '/sbin/nologin')."

A: Use pipe https://jmespath.org/specification.html#pipe-expressions or 与表达式 https://jmespath.org/specification.html#grammar。例如

    - getent:
        database: passwd
    - set_fact:
        myusers: "{{ getent_passwd|dict2items|json_query(query) }}"
      vars:
        myuid: 1000
        myshell: /usr/sbin/nologin
        query: "[?to_number(value[1]) >= to_number('{{ myuid }}')] |
                [?value[5] == '{{ myshell }}'].{user: key, uid: value[1], shell: value[5]}"
    - debug:
        var: myusers

give

    "myusers": [
        {
            "user": "libvirt-qemu", 
            "shell": "/usr/sbin/nologin", 
            "uid": "64055"
        }, 
        {
            "user": "nobody", 
            "shell": "/usr/sbin/nologin", 
            "uid": "65534"
        }
    ]

拟合变量和比较运算符 https://jmespath.org/specification.html#comparison-operators满足您的需求。

json_query 中的管道可能被视为反模式。所以与表达式 https://jmespath.org/specification.html#grammar应使用而不是管道。例如

  query: "[?(to_number(value[1]) >= to_number('{{ myuid }}')) &&
            (value[5] == '{{ myshell }}')].{user: key, uid: value[1], shell: value[5]}"
