這是我的劇本 output.stdout 的回傳是一個串列，這就是我通過索引 0 呼叫它的原因

這是我使用 regex101.com 檢查的 show_version.yaml 檔案，一切正常，但我得到所有鍵的空值。

為什么我得到空值？
uj5u.com熱心網友回復：
我認為您必須設定選項匯出：
- name: match version values
pattern_group:
- name: match name
pattern_match:
regex: "^(\\S ) uptime is"
content: "{{ item }}"
register: name
export: yes
如果沒有這個指令，包含的變數和值將不會被發送回劇本進行進一步處理。
其次，我沒有看到具有內容的實用程式：“{{ item }}”？
- name: match version values
pattern_group:
- name: match name
pattern_match:
regex: "^(\\S ) uptime is"
register: name
我建議你使用 -vvv （非常冗長）來解決一些匹配問題
所以我看到您已將匯出設定為 playbook json_template，我認為也是正確的..
編輯
我認為 ^ 它不被視為行的開始
你能試試： 正則運算式：“\n(\\S ) 正常運行時間是”
uj5u.com熱心網友回復：
我在pattern_group @frenchy 中使用export yes 并在facts 中注冊該值并且它運行良好。你有權利我不需要物品。
