如何仅在POSTMAN响应中返回特定字段？

Question

我正在访问第三方 API（不是公共 API），我只想获取特定字段。如何做到这一点？

假设我有一个 API

{{URL}}/api/records/:recordId

，它返回以下内容：

{
  "id": 707348,
  "created-at": "2024-04-08T14:28:23-07:00",
  "updated-at": "2024-04-08T14:28:24-07:00",
  "currency": {
    "code": "USD"
  },
  "approvals": [
    {
      "id": 5612517,
      "created-at": "2024-04-08T14:28:24-07:00",
      "updated-at": "2024-04-08T14:28:46-07:00",
      "position": 1,
      "approval-chain-id": 729,
      "status": "approved"
    },
    {
      "id": 5612518,
      "created-at": "2024-04-08T14:28:42-07:00",
      "updated-at": "2024-04-08T14:28:42-07:00",
      "position": 2,
      "approval-chain-id": null,
      "status": "pending_approval"
    }
  ]
}

在这里，如果我添加这样的查询参数，

{{URL}}/api/records/:recordId?fields=["id", "created-at"]

然后我会得到想要的结果：

{
    "id": 707348,
    "created-at": "2024-04-08T14:28:23-07:00"
}

我怎样才能检索

currency

（一个对象）或该对象中的某些值？与

approvals

相同，它是一个数组。

如果我这样做

{{coupa_url}}/api/invoices/:invoiceId?fields=["currency"]

那么我只会得到一个带有

200

响应的空数组。

Answer 1

我能够使用

fields

如下所示获得所需的结果。

即，

{{URL}}/api/records/:recordId?fields=["id", "created-at",{"currency":{}}]

返回下方。

{
  "id": 707348,
  "created-at": "2024-04-08T14:28:23-07:00",
  "currency": {
    "code": "USD"
  }
}

{{URL}}/api/records/:recordId?fields=["id", "created-at",{"approvals":{}}]

返回下方。

{
  "id": 707348,
  "created-at": "2024-04-08T14:28:23-07:00",
  "approvals": [
    {
      "id": 5612517,
      "created-at": "2024-04-08T14:28:24-07:00",
      "updated-at": "2024-04-08T14:28:46-07:00",
      "position": 1,
      "approval-chain-id": 729,
      "status": "approved"
    },
    {
      "id": 5612518,
      "created-at": "2024-04-08T14:28:42-07:00",
      "updated-at": "2024-04-08T14:28:42-07:00",
      "position": 2,
      "approval-chain-id": null,
      "status": "pending_approval"
    }
  ]
}
