如何在遍历with_item调试列表时基于传递when条件来执行Ansible任务

Question

我正在尝试基于with_item用户列表上的when条件执行API POST。从API GET收集when条件，然后将其存储为调试变量。

问题：调试变量似乎没有正确迭代，API POST任务只遵循第一个结果。这将导致尝试对with_items列表中的所有项目执行POST，或者跳过所有项目。

我不明白是否每个"request_ad_user"都在创建一个新变量，以及它们是如何在"when"条件下迭代的。我错过了什么？

这是我的代码：

- name: Add a users to univention AD server.
hosts: localhost
tasks:
- name: Include user to add as variable
include_vars:
file: users.yaml
name: users
- name: Check if AD users exist (object DN)
uri:
url: https://10.10.10.10/univention/udm/users/user/uid%3D{{item.username}}%2Ccn%3Dusers%2Cdc%3Dcybertax%2Cdc%3Dcso%2Cdc%3Dcom
user: admin
password: "{{users.adminpw}}"
validate_certs: no
return_content: yes
status_code: 200,404
method: GET
timeout: 10
with_items:
- "{{users.user}}"
register: request_ad_user
- name: debug univention user object DN request
debug:
var: request_ad_user
- name: Add AD user accounts
uri:
url: https://10.10.10.10/univention/udm/users/user/
user: admindh
password: "{{users.vcenterPassword}}"
validate_certs: no
return_content: yes
status_code: 201
method: POST
body: "{"uuid": "string", "uri": "https://10.104.8.110/univention/udm/users/user/uid={{item.username}},dc=cybertax,dc=cso,dc=com", "options": {"pki": false}, "policies": {"pol
body_format: json
when:
- request_ad_user.results[0].status == 404
with_items:
- "{{users.user}}"

尝试添加循环索引，并在when子句中使用该索引：

- name: Add AD user accounts
uri:
url: https://10.10.10.10/univention/udm/users/user/
user: admindh
password: "{{users.vcenterPassword}}"
validate_certs: no
return_content: yes
status_code: 201
method: POST
body: "{"uuid": "string", "uri": "https://10.104.8.110/univention/udm/users/user/uid={{item.username}},dc=cybertax,dc=cso,dc=com", "options": {"pki": false}, "policies": {"pol
body_format: json
when:
- request_ad_user.results[ndx].status == 404
with_items:
- "{{users.user}}"
loop_control:
index_var: ndx
