由于变量格式问题，无法获取 ansible 中现有目录的统计信息

问题描述 投票：0回答：1

我正在尝试将第一个目录的所有者传递给ansible变量

source_files

我们无法控制 Ansible 变量 

source_files
，因为它是通过某些 OLAM api 构造的。我已经为此示例对其进行了硬编码。

source_files
变量的两个文件都存在，如下所示：

[wluser@mylocalhost ~]$ ls -ltr '/tmp/my  private.txt' /tmp/files.sh

-rw-r--r-- 1 wluser mygrp 0 Nov 12 21:52 /tmp/files.sh

-rw-r--r-- 1 wluser mygrp 0 Nov 12 21:52 /tmp/my  private.txt

剧本：

[wluser@mylocalhost ~]$ cat formatstring.yml

---

  hosts: localhost
  any_errors_fatal: True
  gather_facts: no

   - name: Print source_files

     debug:
       msg: "source_files: {{ source_files }}"
     

   - name: Loop Print source_files

     debug:
       msg: "{{ item }}"
     loop: "{{ source_files.split(',') }}"

 

   - name: Single Print source_files

     debug:
       msg: "{{ source_files.split(',')[0] }}"
   
 

   - name: Get directory owner

     ansible.builtin.stat:
       path: "{{ tomcat_home_item }}"
     register: dir_stat
     vars:
       tomcat_home_item: "{{ source_files.split(',')[0] | trim }}"

 
   - name: Store directory owner's UID in a variable

     set_fact:

       owner_uid: "{{ dir_stat.stat.pw_name | default('baduser') }}"


   - debug:
       msg: "Detected user is: {{ owner_uid }}"

 

   - name: Get directory owner

     ansible.builtin.stat:
       path: "{{ tomcat_home_item | regex_replace('^\\s*'|'\\s*$', '') }}"
     register: dir_stat
     vars:
       tomcat_home_item: "{{ source_files.split(',')[0] | trim }}"

 

   - name: Store directory owner's UID in a variable

     set_fact:
       owner_uid: "{{ dir_stat.stat.pw_name | default('baduser') }}"
 

   - debug:

       msg: "Detected user is: {{ owner_uid }}"

输出：

[wluser@mylocalhost ~]$ ansible-playbook formatstring.yml -vvv

ansible-playbook 2.8.4

  config file = /etc/ansible/ansible.cfg

如您所见，由于变量 

baduser
的引用/格式问题，我得到的是 
wluser
而不是正确的用户 
source_files
。

然后我尝试删除引号，但这导致了运行时错误。

考虑到剧本中最初提到的 source_files 的格式无法更改，您能否建议我如何获取文件的统计信息。

考虑到

source_files

的格式，如何获取文件的统计信息

假设

ls -ltr
命令的输出是正确的，以及
source_files
的内容，对于

~/test$ ls -ltr 'test file' 'test path' 'test path/test file'
-rw-r--r--. 1 ansible_user users    0 Nov 13 08:00 test file
-rw-r--r--. 1 ansible_user users    0 Nov 13 08:00 test path/test file

test path:
total 0
-rw-r--r--. 1 ansible_user users 0 Nov 13 08:00 test file

一个最小的示例手册


```---
- hosts: localhost
  become: false
  gather_facts: false

  vars:

    FILE: 'test file'
    PATH: 'test path'

  tasks:

  - set_fact:
      SOURCE_FILES: "'test file','test path/test file'"

  - stat:
      path: 'test file'
    register: result

  - debug:
      msg: "{{ result.stat.path }}"

  - stat:
      path: "{{ FILE }}"
    register: result

  - debug:
      msg: "{{ result.stat.path }}"

  - stat:
      path: "{{ PATH }}/{{ FILE }}"
    register: result

  - debug:
      msg: "{{ result.stat.path }}"

  - debug:
      msg:
        - "Content: {{ SOURCE_FILES }}"
        - "List of file: {{ SOURCE_FILES | split(',') }}"

  - stat:
      path: "{{ SOURCE_FILES | split(',') | first | replace(\"'\",'') }}"
    register: result

  - debug:
      msg: "{{ result.stat.path }}"

  - stat:
      path: "{{ SOURCE_FILES | split(',') | last | replace(\"'\",'') }}"
    register: result

  - debug:
      msg: "{{ result.stat.path }}"

将产生
