我想通過這個陣列中的每個對象來循環，並挑選出每個鍵的所謂的值AssetId和console.log()它。我該如何在命令行中使用jq來做到這一點？

請更清楚它是否是一個[JQ]的問題或[jQuery的]的問題。他們不是一樣的，不應該一起使用......你的問題在你如何標記和詢問它的方式上完全不明確。 –

命令行工具jq寫入STDOUT和/或STDERR。如果你想要寫的.AssetId信息輸出到標準輸出，那麼一種可能是如下：

jq -r ".[] | .AssetId" input.json

輸出：

一個更強大的咒語是：.[] | .AssetId?，但你的選擇將取決於如果沒有名爲「AssetId」的鍵，您需要什麼。

謝謝，非常有幫助的答案！ –

注意：如何將每個函數發送到一個函數？ –

嘗試此操作後，我發現一個錯誤。它說意外的字符串。 –

你也可以通過這個命令來完成。

jq ".[].AssetId" input.json

如果數組一樣是這是在我的情況

{ 
    "resultCode":0, 
    "resultMsg":"SUCCESS", 
    "uniqueRefNo":"111222333", 
    "list":[ 
     { 
     "cardType":"CREDIT CARD", 
     "isBusinessCard":"N", 
     "memberName":"Bank A", 
     "memberNo":10, 
     "prefixNo":404591 
     }, 
     { 
     "cardType":"DEBIT CARD", 
     "isBusinessCard":"N", 
     "memberName":"Bank A", 
     "memberNo":10, 
     "prefixNo":407814 
     }, 
     { 
     "cardType":"CREDIT CARD", 
     "isBusinessCard":"N", 
     "memberName":"Bank A", 
     "memberNo":10, 
     "prefixNo":413226 
     } 
    ] 
}

你可以用下面的命令JQ拿到prefixNo。

jq ".list[].prefixNo" input.json

有關陣列更具體的情況下迭代上JQ你可以檢查this blogpost
