在两个列表中迭代时，将相同的值追加两次

Question

我的可靠策略：

- hosts: localhost
connection: local
gather_facts: no
become: no
vars:
- delete: [
{
"department_link": "https://servicenowservices.com/api/now/table/da/3fb1",
"hostname": "host1",
"value": "3fb1"
},
{
"department_link": "https://servicenowservices.com/api/now/table/da/3fb1",
"hostname": "host2",
"value": "3fb1133"
}
]
tasks:
- name: connect to service now cmdb table
uri:
url: "{{item.department_link}}"
method: GET
body_format: form-urlencoded
user: "user"
password: "password"
timeout: 200
validate_certs: no
loop: "{{delete}}"
register: test
no_log: yes
- debug:
var: test.results
- name: combine
set_fact:
final: "{{ final | default([]) + [ item[0] | combine({'department': item[1].json.result.name | default(None)}) ]  }}"
when:
- item[1].json.result.sys_id | string == item[0].value | string
with_nested:
- "{{delete}}"
- "{{test.results}}"
no_log: yes
- debug:
var: final

var的调试：test.results--截断。--请转到页面末尾查看完整输出。

"test.results": [
"json": {
"result": {
"name": "dept1",
"sys_id": "3fb1",
}
},
"json": {
"result": {
"name": "dept1",
"sys_id": "3fb1",
}
}]

var的调试：final

ok: [localhost] => {
"final": [
{
"department": 'dept1",
"department_link": "https://servicenowservices.com/api/now/table/da/3fb1",
"hostname": "host1",
"value": "3fb1"
},
{
"department": "dept1",
"department_link": "https://servicenowservices.com/api/now/table/da/3fb1",
"hostname": "host1",
"value": "3fb1"
}
]
}

从上面可以看出，当我遍历两个列表，并在条件满足时将两个列表合并为一个列表时，出于某种原因，它将输出两次。我尝试了很多不同的方法，但没有成功。

所以我想要的结果是：对于var:final-我希望输出在列表中只有一个dict，就像一样

"final": [
{
"department": 'dept1",
"department_link": "https://servicenowservices.com/api/now/table/da/3fb1",
"hostname": "host1",
"value": "3fb1"
}]

请告诉我怎样才能做到这一点。

以下是test.results的完整输出，我也打印了它的类型。希望这会有所帮助！！

Answer 1

您面临这个问题是因为test.results-variabel有重复的json块。

我已经删除了他们使用地图和独特的功能

请尝试此修改后的任务

- name: combine
set_fact:
final: "{{ final | default([]) + [ item[0] | combine({'department': item[1].result.name | default(None)}) ]  }}"
when:
- item[1].result.sys_id | string == item[0].value | string
with_nested:
- "{{delete}}"
- "{{test.results | map(attribute='json') | unique }}"
no_log: yes
