如何從json獲取id？

Question

鑒於我有以下 json：

{
  "id": "images",
  "type": "collection",
  "href": "https://api.ionos.com/cloudapi/v5/images",
  "items": [
    {
      "id": "2bdfc61e-1ff7-11ea-af1c-525400f64d8d",
      "type": "image",
      "href": "https://api.ionos.com/cloudapi/v5/images/2bdfc61e-1ff7-11ea-af1c-525400f64d8d",
      "metadata": {
        "etag": "b1a133b9ac038de9157572bbc3491898",
        "createdDate": "2019-12-16T11:28:24Z",
        "createdBy": "System",
        "createdByUserId": "System",
        "lastModifiedDate": "2019-12-16T11:28:24Z",
        "lastModifiedBy": "System",
        "lastModifiedByUserId": "System",
        "state": "AVAILABLE"
      },
      "properties": {
        "name": "windows-2008-r2-server-2019-12",
        "description": "",
        "location": "gb/lhr",
        "size": 18,
        "cpuHotPlug": true,
        "cpuHotUnplug": false,
        "ramHotPlug": false,
        "ramHotUnplug": false,
        "nicHotPlug": true,
        "nicHotUnplug": true,
        "discVirtioHotPlug": true,
        "discVirtioHotUnplug": false,
        "discScsiHotPlug": false,
        "discScsiHotUnplug": false,
        "licenceType": "WINDOWS",
        "imageType": "HDD",
        "imageAliases": [
          "windows:2008r2"
        ],
        "public": true
      }
    },
    {
      "id": "d65c184b-cd78-11e9-b88c-525400f64d8d",
      "type": "image",
      "href": "https://api.ionos.com/cloudapi/v5/images/d65c184b-cd78-11e9-b88c-525400f64d8d",
      "metadata": {
        "etag": "f3f490ba129dbb56b4dd0f97870240b8",
        "createdDate": "2019-09-02T11:57:28Z",
        "createdBy": "System",
        "createdByUserId": "System",
        "lastModifiedDate": "2019-09-02T11:57:28Z",
        "lastModifiedBy": "System",
        "lastModifiedByUserId": "System",
        "state": "AVAILABLE"
      },
      "properties": {
        "name": "ubuntu-16.04.6-server-amd64.iso",
        "description": "",
        "location": "gb/lhr",
        "size": 0.86,
        "cpuHotPlug": true,
        "cpuHotUnplug": false,
        "ramHotPlug": true,
        "ramHotUnplug": false,
        "nicHotPlug": true,
        "nicHotUnplug": true,
        "discVirtioHotPlug": true,
        "discVirtioHotUnplug": true,
        "discScsiHotPlug": false,
        "discScsiHotUnplug": false,
        "licenceType": "LINUX",
        "imageType": "HDD",
        "imageAliases": [
          "ubuntu:16.04_iso"
        ],
        "public": true
      }
    },

  ]
}

我需要在其properties具有"licenceType": "LINUX"和"imageType": "HDD" items找到第一個id 。

這是我試過的代碼：

$.items[?(@.properties.imageType=="HDD" 
        @.properties.licenceType=="LINUX" )].id

在我的例子中，它應該返回d65c184b-cd78-11e9-b88c-525400f64d8d

但是，它沒有給我任何東西。

Answer 1

你必須AND兩個查詢，所以這應該有效

$..items[?(@.properties.imageType=="HDD" && @.properties.licenceType=="LINUX" )].id

如果需要第一個元素，則

$..items[0].id
