不循环删除JSON行列

Question

我有一个返回JSON数据的API。但是现在我想删除一些数据，而不需要遍历整个对象。

示例JSON数据是：

[
{
"cost":"KES 0.8000",
"messageId":"ATXid_0fae395279b54d51519de5581230a7e8",
"messageParts":1,
"number":"+2547112xxxxxx",
"status":"Success",
"statusCode":101
},
{
"cost":"KES 0.8000",
"messageId":"ATXid_19a0a09efcf39e87245a57f6403631d5",
"messageParts":1,
"number":"+2547112xxxxxx",
"status":"Success",
"statusCode":101
},
{
"cost":"0",
"messageId":"None",
"number":"+25470000000000",
"status":"InvalidPhoneNumber",
"statusCode":403
}
]

我只想提取以下数据：

[
{
"number":"+2547112xxxxxx",
"status":"Success"
},
{
"number":"+2547112xxxxxx",
"status":"Success"
},
{
"number":"+25470000000000",
"status":"InvalidPhoneNumber"
}
]

我正在使用Node.js和快速框架。

Answer 1

以简单的方式，使用.map()函数，您可以这样做：

console.log(arr.map(({number, status}) => ({
  number,
  status
})));

const arr = [{
    "cost": "KES 0.8000",
    "messageId": "ATXid_0fae395279b54d51519de5581230a7e8",
    "messageParts": 1,
    "number": "+2547112xxxxxx",
    "status": "Success",
    "statusCode": 101
  },
  {
    "cost": "KES 0.8000",
    "messageId": "ATXid_19a0a09efcf39e87245a57f6403631d5",
    "messageParts": 1,
    "number": "+2547112xxxxxx",
    "status": "Success",
    "statusCode": 101
  },
  {
    "cost": "0",
    "messageId": "None",
    "number": "+25470000000000",
    "status": "InvalidPhoneNumber",
    "statusCode": 403
  }
];
console.log(arr.map(({number, status}) => ({
  number,
  status
})));
