Ansible 2.8.7 API 使用异常4：playbook执行powershell脚本返回值“\r\n”，原因分析及解决

Q1: Ansible2.8.7和2.7.9通过Playbook执行powershell脚本返回值问题, 系统环境一样

Q2: 如果get_w_sysinfo.ps1里直接写内置命令，如ipconfig，又能正常返回输出，原因不详

#1. get_w_sysinfo.ps1

get-wmiobject win32_computersystem |Select-Object Name,Domain,SystemType,Model

#2.get_w_sysinfo.yml

- name: test script module
  hosts: winclient
  gather_facts: F
  tasks:
    - name: run test script
      script: /etc/ansible/scripts/windows/get_w_sysinfo.ps1
      register: ps_out
    - name: show
      debug: var=ps_out.stdout verbosity=0

#3.执行

[root@CENTOS768-1810 ~]#  ansible-playbook playbook/get_w_sysinfo.yml

#4.Ansible2.8.7执行结果

[root@CENTOS768-1810 ~]# ansible-playbook playbook/get_w_sysinfo.yml -vvvvv

#5. Ansible2.7.9执行结果

#6. Ansible2.8.7解决方法

# 经观摩官方.ps1文件,发现返回为JSON数据,所以尝试以下：
#!powershell
$result = get-wmiobject win32_computersystem |Select-Object Name,Domain,UserName,SystemType,Model,HypervisorPresent,InstallDate
$result | ConvertTo-Json  -Depth 4
