我是 ansible 和 jinja 模板中的菜鸟，我需要从 uri json 结果中获取一个值，但我不知道该怎么做。
我在下面有 uri 请求：
- name: Busca o id do usuario na Gitlab API
uri:
url: "{{ gitlab_host_server }}/api/v4/users?access_token={{ gitlab_access_token }}&username={{ item.key }}"
method: GET
status_code: 200,400
headers:
"Content-Type": "application/json"
"Accept": "application/json"
"Cache-Control": "no-cache"
"content-type": "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW"
body_format: json
return_content: yes
register: gitlab_api_usuario
when: item['value'].hostname == "{{ ansible_hostname }}"
with_dict: "{{ hostname_desenvolvedores }}"
所以我从变量中获取寄存器gitlab_api_usuario当我使用下面的调试时，我得到以下结果。
- debug:
var: "{{ item }}"
with_items: "gitlab_api_usuario.results | map(attribute='content') | list"
结果：
ok: [192.168.101.151] => (item=None) => {
"gitlab_api_usuario.results | map(attribute='content') | list": "[Undefined, Undefined, Undefined, Undefined, Undefined, Undefined, Undefined, Undefined, Undefined, Undefined, Undefined, Undefined, Undefined, Undefined, u'[{"id":8,"name":"Maycon Brito","username":"maycon.brito","state":"active","avatar_url":"http://192.168.101.181:8083/uploads/-/system/user/avatar/8/956667.jpeg","web_url":"http://192.168.101.181:8083/maycon.brito","created_at":"2018-05-15T09:33:02.866-03:00","bio":null,"location":null,"skype":"","linkedin":"","twitter":"","website_url":"","organization":null,"last_sign_in_at":"2018-05-15T16:39:53.045-03:00","confirmed_at":"2018-05-15T09:33:02.584-03:00","last_activity_on":"2018-05-21","email":"mayconbrito@teste.rede.teste","theme_id":1,"color_scheme_id":1,"projects_limit":100000,"current_sign_in_at":"2018-05-17T17:19:13.442-03:00","identities":[],"can_create_group":true,"can_create_project":true,"two_factor_enabled":false,"external":false,"is_admin":true}]', Undefined]"
}
因此，我需要从唯一的成功请求中获取id值。

我不知道为什么，但您的过滤不会导致列表变量：
- name: print results
debug:
msg: item
loop: "{{ gitlab_api_usuario.results | map(attribute='content') | list }}"
输出：
TASK [print results] ************************************************************************************************************************************************************************************************

Hint: If you passed a list/dict of just one element, try adding wantlist=True to your lookup invocation or use q/query instead of lookup."}
您可以改用它：
- name: print results
set_fact:
final_var: "{{ item.content }}"
when: item.content is defined
loop: "{{ gitlab_api_usuario.results }}"
- name: print results
debug:
var: final_var[0].id
它将获得包含content属性(即单个字典元素的列表(的唯一(如您的问题中所述(结果，然后从第一个(和唯一(元素中选取id属性。
