檢查一個鍵是否存在并回傳另一個鍵

如果 Gitlab 作業 ID 包含工件，我需要 jq 語法方面的幫助。JSON 輸出看起來像這樣（從中洗掉了很多不相關的資訊并添加了[...]）：

我一直在嘗試使用 jQ 執行以下任一操作：

任何一個：

• 檢查artifacts_file每次迭代中是否存在 key 以及是否回傳 (job) id (so .[].id)

• 檢查artifacts每次迭代中陣列是否為空，如果為空，則回傳（作業）ID。

在這兩種情況下，我都能完成第一部分，但我不確定如何回傳.id密鑰。

我一直在嘗試利用并適應我的案例的相關 stackoverflow 問題：

• jq - 如果長度不為空，則回傳陣列值
• 如何在迭代值之前檢查 jq 中是否存在“鍵”

到目前為止我所擁有的：jq '[.[].artifacts[]|select(length > 0)] | .[]'它回傳找到的所有工件（但它不包含.id作業的）。

uj5u.com熱心網友回復：

使用檢查欄位的存在has：

.[] | select(has("artifacts_file")).id

3219589878
3219589876

演示

通過將欄位與以下內容進行比較來檢查欄位是否為空陣列[]：

.[] | select(.artifacts == []).id

3219589880
