我們有一個場景，我們需要在一個json檔案的分發中替換CacheBehaviour的TargetOriginID。我們需要用新值替換現有的 TargetOriginID。我已經嘗試使用下面的 jq 命令但沒有更接近
for targetoriginID in $(jq '(.CacheBehaviors.Items[].TargetOriginId)' distconfig.json);
do
echo "#######fetch the new value from change behaviour json file"#######
NewValue=$(jq -r "map(select(.targetoriginid == ""$targetoriginID""))[].targetorigindr" changebehaviour.json)
echo "#########replace value in dist config json file with new value from change behaviour###########"
jq -r '(.CacheBehaviors.Items[].TargetOriginId | select(. == "$targetoriginID")) = "$NewValue"' distconfig.json > "tmp" && mv "tmp" distconfig.json

尋找一種解決方案來對所有 TargetOriginID 的 CacheBehaviour 進行批量更改

修復（即有效）并將您的 JSON 輸入減少到必要的最小值（MRE中的 M ），即 50 行。

您可能希望運行類似于以下內容的 jq 程式：
(.CacheBehaviors.Items[].TargetOriginId | select(. as $id | "nkl" | IN($id[]))) = ["wkl"]
它選擇所有TargetOriginId包含該值的 s 并將"nkl"串列更改為僅包含"wkl"。
輸出：
{
"CacheBehaviors": {
"Quantity": 2,
"Items": [
{
"PathPattern": "jkl/*",
"TargetOriginId": [
"wkl"
],
"TrustedSigners": {

},

}
從這個問題不清楚是否"TargetOriginId": ["nkl", "xyz"]應該成為["wkl"]或["wkl", "xyz"]。或者是否["nkl", "xyz"]匹配，因為它也包含不同的值。也許您只想選擇完整TargetOriginId陣列匹配的那些？
如果您只想匹配具有單值目標源 id 的專案，程式會變得更簡單一些：
(.CacheBehaviors.Items[].TargetOriginId | select(. == ["nkl"])) = ["wkl"]
如果您的目標來源 id 始終是一個陣列，并且您想將“[abc,nkl,xyz]”更改為“[abc,REPLACED,xyz]”，則僅選擇這些陣列元素并為其分配新值。
新輸入（據我了解，Q 對此非常模糊）：
{
"CacheBehaviors": {
"Quantity": 2,
"Items": [
{
"PathPattern": "jkl/*",
"TargetOriginId": [
"nkl",
"something else"
]
},
{
"PathPattern": "fgh/*",
"TargetOriginId": [
"xyz",
"abc"
]
}
]
},
"IsIPV6Enabled": true
}
jq:
(.CacheBehaviors.Items[].TargetOriginId[] | select(. == "nkl")) = "wkl"
輸出：
{
"CacheBehaviors": {
"Quantity": 2,
"Items": [
{
"PathPattern": "jkl/*",
"TargetOriginId": [
"wkl",
"something else"
]
},
{
"PathPattern": "fgh/*",
"TargetOriginId": [
"xyz",
"abc"
]
}
]
},
"IsIPV6Enabled": true
}

在撰寫本文時，發布的 JSON 是無效的，因此不清楚究竟需要什么，但以下是說明性的：
jq --arg newvalue xyz '
(.. | objects | select(has("TargetOriginId")) | .TargetOriginId) |= $newvalue
'
uj5u.com熱心網友回復：
提供一些假設的第二個答案。讓我們從一個最小的示例輸入開始：
{
"CacheBehaviors": {
"Quantity": 2,
"Items": [
{
"PathPattern": "jkl/*",
"TargetOriginId": [
"nkl",
"something else"
]
},
{
"PathPattern": "fgh/*",
"TargetOriginId": [
"xyz",
"abc"
]
}
]
},
"IsIPV6Enabled": true
}
假設你想定義一個映射“{old1: new1, old2: new2, old3: new3, ...}”，下面的程式可以作業并且很容易擴展：
(.CacheBehaviors.Items[].TargetOriginId[]) |= ({
nkl: "wkl",
xyz: "123",
"something else": "is changed too",
"not found": "rever replaced"
}[.] // .)
如果您希望將映射放在程式的頂部/開頭，請將其系結到變數：
{
nkl: "wkl",
xyz: "123",
"something else": "is changed too",
"not found": "rever replaced"
} as $mapping
| (.CacheBehaviors.Items[].TargetOriginId[]) |= ($mapping[.] // .)
運行上述程式后的輸出：
{
"CacheBehaviors": {
"Quantity": 2,
"Items": [
{
"PathPattern": "jkl/*",
"TargetOriginId": [
"wkl",
"is changed too"
]
},
{
"PathPattern": "fgh/*",
"TargetOriginId": [
"123",
"abc"
]
}
]
},
"IsIPV6Enabled": true
}
這就是你所追求的嗎？這會從物件/字典/映射中按鍵選擇新值，如果未找到映射，則回退到當前值。
… |= ({ old: "new" }[.] // .)
映射本身可以作為來自單獨檔案的 jq 的引數提供：
jq --slurpfile mapping old_to_new_ids.json \
'(.CacheBehaviors.Items[].TargetOriginId[]) |= ($mapping[0][.] // .)'
該檔案old_to_new_ids.json將僅包含以下內容：
{
"nkl": "wkl",
"xyz": "123",
"something else": "is changed too",
"not found": "rever replaced"
}
