我在mysql数据库中有一个类似结构的json。
{
"tagId": "17",
"label": "Signature",
"name": "Signature",
"key": "Signature",
"placeholder": "Sign Here",
"type": "printDigital",
"children": [
{
"name": "Signature",
"key": "Signature",
"type": "signatureText",
"label": "Signature",
"placeholder": "Sign Here"
},
{
"name": "SignerUUID",
"key": "SignerUUID",
"type": "userUuid",
"label": "UUID",
"placeholder": "UUID"
}
]
}
我想针对下面这样的密钥签名更新子json中name字段的值
{
"tagId": "17",
"label": "Signature",
"name": "Signature",
"key": "Signature",
"placeholder": "Sign Here",
"type": "printDigital",
"children": [
{
"name": "SignHere",
"key": "Signature",
"type": "signatureText",
"label": "Signature",
"placeholder": "Sign Here"
},
{
"name": "SignerUUID",
"key": "SignerUUID",
"type": "userUuid",
"label": "UUID",
"placeholder": "UUID"
}
]
}
如何有效地更新上述值?
