[英]Need to find key-value pair and replace key-value pair in JSON using JQ
我有這個 JSON
{
"firstName": "Rajesh",
"lastName": "Kumar",
"gender": "man",
"age": 24,
"address": {
"streetAddress": "126 Udhna",
"city": "Surat",
"state": "WB",
"postalCode": "394221"
},
"phoneNumbers": [
{
"type": "home",
"number": "7383627627"
}
]
}
我需要使用 JQ 找到“狀態”鍵的值並替換 JSON 中的值。我不想通過提供鍵的 position 來獲取它,就像
firstName=$(cat sample-json.json | jq -r '.firstName')
我預計 output
{
"firstName": "Rajesh",
"lastName": "Kumar",
"gender": "man",
"age": 24,
"address": {
"streetAddress": "126 Udhna",
"city": "Surat",
"state": "Bihar",
"postalCode": "394221"
},
"phoneNumbers": [
{
"type": "home",
"number": "7383627627"
}
]
}
如果您願意指定地址:
jq '.address.state = "Bihar"' sample-json.json
否則:
jq 'walk(if type == "object" and has("state") then .state = "Bihar" else . end)' sample-json.json
最后一個將替換所有.state
值。 如果您只想替換第一次出現:
jq 'first(..|objects|select(has("state"))).state = "Bihar"' sample-json.json
等等。 如果你能把要求說清楚,那真的對所有相關人員都有幫助。
