使用 ansible playbook 和查找插件，如何將curl https://ifconfig.io/all具有字典格式的“”的結果轉換key: value為專案串列
country_code: US
encoding: gzip
forwarded: 29.493.593.012
host: XXX.XXX.X53.2XX
ifconfig_hostname: ifconfig.io
ip: XXX.XXX.X53.2XX
lang: ""
method: GET
mime: '/'
port: 27404
referer: ""
ua: Python-urllib/3.6
所需的輸出：此格式的專案串列：
[
{
"key": "country_code",
"value": "US"
},
{
"key": "encoding",
"value": "gzip"
},
{
"key": "forwarded",
"value": "29.493.593.012"
},
{
"key": "host",
"value": "XXX.XXX.X53.2XX"
},
{
"key": "ifconfig_hostname",
"value": "ifconfig.io"
},
{
"key": "ip",
"value": "XXX.XXX.X53.2XX"
},
{
"key": "lang",
"value": "''"
},
{
"key": "method",
"value": "GET"
},
{
"key": "mime",
"value": "''"
},
{
"key": "port",
"value": "28180"
},
{
"key": "referer",
"value": "''"
},
{
"key": "ua",
"value": "Python-urllib/3.6"
}
]
我使用的腳本是：
- name: Get url contents
vars:
curl_res: "{{ query('url','https://ifconfig.io/all') }}"
debug:
msg: "{{ item }}"
loop: "{{ curl_res | dict2items }}"
但我有這個錯誤：
TASK [Get url contents] *****************************************************************************************************************
fatal: [servera]: FAILED! => {"msg": "Unexpected templating type error occurred on ({{ curl_res | dict2items }}): dict2items requires a dictionary, got <class 'list'> instead."}
因此，我手動制作，將 curl 結果保存在本地檔案中，然后將其微調為以下格式：
cat files/curl_result
{
"country_code": "US",
"encoding": "gzip",
"forwarded": "29.493.593.012",
"host": "XXX.XXX.X53.2XX",
"ifconfig_hostname": "ifconfig.io",
"ip": "XXX.XXX.X53.2XX",
"lang": "''",
"method": "GET",
"mime": "''",
"port": "28580",
"referer": "''",
"ua": "Python-urllib/3.6"
}
然后，我在我的游戲中運行了這個任務：
- name: extract from file
vars:
items_curl_res: "{{ lookup('file', 'curl_result') | from_json | dict2items }}"
debug:
var: items_curl_res

您得到的回傳不是字典，而是表單中的字串串列key: value。
該表單實際上是一種有效的 YAML 格式，因此您可以使用過濾器對所有這些字串map應用from_yaml過濾器，然后map是串列dict2items，最后flatten是串列。
結束這個任務：
- debug:
var: >-
query('url','https://ifconfig.io/all')
| map('from_yaml')
| map('dict2items')
| flatten
該任務將產生：
query('url','https://ifconfig.io/all') | map('from_yaml') | map('dict2items') | flatten:
- key: country_code
value: BE
- key: encoding
value: gzip
- key: forwarded

- key: host

- key: ifconfig_hostname
value: ifconfig.io
- key: ip
value: 93.184.216.34
- key: lang

- key: port

- key: referer

哇..它正在作業，謝謝β.εηοιτ.βε：
這里的作業腳本：
- name: Get url contents
debug:
msg: "{{ query('url','https://ifconfig.io/all') | map('from_yaml') | map('dict2items') | flatten }}"
和輸出：
"msg": [
{
"key": "country_code",
"value": "US"
},
{
"key": "encoding",
"value": "gzip"
},
{
"key": "forwarded",
"value": "XXX.XX3.8XX.X9X"
},
{
"key": "host",
"value": "XXX.XX3.8XX.X9X"
},
{
"key": "ifconfig_hostname",
"value": "ifconfig.io"
},
{
"key": "ip",
"value": "3XX.X7X.XX4.XX0"
},
