我有一个list，它实际上是一个dict 的键列表。我想得到一个连接字符串，其中dict 在这个list 的键上过滤，并在模块选项中使用它。
我的用例是拥有公钥名称列表以生成授权密钥文件的用户。

2 - hosts: localhost

4 vars:
5 pub_keys:
6 key01: ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQ[…]5/ someuser@somehost
7 key02: ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQ[…]ea otheruser@somewher
8 key03: ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQ[…]dN anyser@anyhost
9 users:
10 root:
11 home: /root
12 shell: /bin/bash
13 authorized_keys:
14 - key01
15 mgmtusr:
16 home: /home/mgmtusr
17 shell: /bin/bash
18 authorized_keys:
19 - key01
20 - key02
21 - key03
22
23 tasks:
24 - name: Debug Authorized Keys
25 debug:
26 msg: "USER:{{ item.key }} AUTHKEYSLIST:{{ pub_keys|selectattr(item.authorized_keys) }}"
27 with_dict: "{{ users }}"
28
29 - name: Manage users Authorized Keys
30 authorized_key:
31 user: "{{ item.key }}"
32 key: "{{ pub_keys|selectattr(item.authorized_keys) }}"
33 exclusive: yes
34 with_dict: "{{ users }}"
35
正如您在此处看到的，我尝试使用dict|selectattr(list)，但失败了。
在调试模块中获取<generator object select_or_reject at 0x…>，当然在authorized_key 模块中获取invalid key specified。

像其他尝试一样 (with_subelements, lookup('template', ...) selectattr 似乎不是解决方案。
有什么建议吗？
