Ansible stdout - 打印不带任何附加字符的文件内容

Question

运行 Ansible playbook，是否有解决方案可以打印文件内容而无需任何额外字符？就像 Linux 上的一只简单的猫。

有简单的文本文件：

  cat /tmp/report-2023-10-19.html.txt
   server1 : The D:\ drive size is WRONG! Expected drive size: '1009'. Current size is: 100
   server2 : The D:\ drive size is WRONG! Expected drive size: '1009'. Current size is: 100
   server3 : The C:\ drive size is WRONG! Expected drive size: '12899'. Current size is: 126.51
   server4 : The C:\ drive size is WRONG! Expected drive size: '12899'. Current size is: 126.51

我想用 Ansible 显示文件内容：

- name: Display all findings
  debug:
   var: "file_content"
  vars:
   file_content: "{{ lookup('file', '/tmp/{{ reportfile }}.txt').splitlines() }}"
  delegate_to: localhost
  run_once: true
  when: num_lines.stdout | int > 0
  tags: always

结果：

  ok: [vmstfsh1 -> localhost] => {
      "file_content": [
          " server1 : The D:\\ drive size is WRONG! Expected drive size: '1009'. Current size is: 100 ",
          "",
          " server2 : The D:\\ drive size is WRONG! Expected drive size: '1009'. Current size is: 100 ",
          "",
          " server3 : The C:\\ drive size is WRONG! Expected drive size: '12899'. Current size is: 126.51 ",
          "",
          " server4 : The C:\\ drive size is WRONG! Expected drive size: '12899'. Current size is: 126.51"
      ]
  }

有没有办法打印文件内容而不带任何额外的字符（“，）？就像Linux上的一只简单的猫一样。 我找到了 ANSIBLE_STDOUT_CALLBACK 变量，但我只能使用此选项（yam 或 json）更改格式。

对于Linux PC，请使用shell命令cat。

对于 Windows PC，请使用 ansible.windows.win_command powershell.exe Get-Content。

对于 Linux 客户端 PC：

- name: Display all findings
  hosts: linux

  tasks:
    - name: Display file content
      shell: cat /tmp/{{ reportfile }}.txt
      register: file_content
      changed_when: false  # Do not mark as changed

    - name: Display file content without extra characters
      debug:
        var: file_content.stdout_lines
      when: file_content.stdout_lines is defined

对于 Windows 客户端 PC：

- name: Display all findings
  hosts: win
  become_method: runas

  tasks:
  - name: Read the file
    ansible.windows.win_command: powershell.exe Get-Content C:\\tmp\{{ reportfile }}.txt
    register: file_content
    changed_when: false  # Do not mark as changed

  - name: Display file content line by line
    debug:
      var: item
    loop: "{{ file_content.stdout_lines }}"
    when: file_content.stdout_lines is defined
