使用該物件中的唯一引數洗掉elasticsearch檔案中物件陣列中的物件

我在 elasticsearch 中有一個檔案是這樣的：

{
  "_index": "user",
  "_type": "_doc",
  "_id": "20",
  "_score": 1,
  "_source": {
    "id": "20",
    "gender": null,
    "uuid": "68de0b74-cdf6-4e21-a046-6876e569e4e3",
    "first_name": null,
    "last_name": null,
    "nick_name": null,
    "email": null,
    "country_code": "98",
    "mobile": "9xxx7",
    "password": null,
    "old_password": null,
    "birthdate": null,
    "email_verified_at": null,
    "created_at": null,
    "updated_at": null,
    "deleted_at": null,
    "old_data": null,
    "devices": [
      {
        "updated_at": "2021-12-14T12:11:26.000000Z",
        "serial": "sr_31",
        "vendor": "folan",
        "created_at": "2021-12-14T12:11:26.000000Z",
        "model": "device_model",
        "id": 4,
        "device_app": {
          "device_id": 4,
          "updated_at": "2021-12-14T12:11:26.000000Z",
          "created_at": "2021-12-14T12:11:26.000000Z",
          "id": 4,
          "uuid": "f60f7df0-5cd6-11ec-b71d-bdfd039f50b3"
        },
        "uuid": "f60a2ae0-5cd6-11ec-81cb-0128d6059ef1"
      },
      {
        "updated_at": "2021-12-14T12:13:07.000000Z",
        "serial": "sr_32",
        "vendor": "folan",
        "created_at": "2021-12-14T12:13:07.000000Z",
        "model": "device_model",
        "id": 5,
        "device_app": {
          "device_id": 5,
          "updated_at": "2021-12-14T12:13:07.000000Z",
          "created_at": "2021-12-14T12:13:07.000000Z",
          "id": 5,
          "uuid": "32481b80-5cd7-11ec-ba02-c33a09f165eb"
        },
        "uuid": "3242f860-5cd7-11ec-9d54-c3339177d9bb"
      }
    ]
  }
}

如您所見，我有一個名為的欄位devices，它是一個物件陣列。我想洗掉它的第一個元素不是通過選擇陣列的索引號而是通過陣列的內容，這意味著**我想給腳本一個serial欄位（每個設備都是唯一的）并洗掉整個物件對應的物件。

比方說，我想要一些輸入，sr_31而輸出將是這樣的（僅sr_31省略了物件 containsgin ）：

{
  "_index": "user",
  "_type": "_doc",
  "_id": "20",
  "_score": 1,
  "_source": {
    "id": "20",
    "gender": null,
    "uuid": "68de0b74-cdf6-4e21-a046-6876e569e4e3",
    "first_name": null,
    "last_name": null,
    "nick_name": null,
    "email": null,
    "country_code": "98",
    "mobile": "9xxx7",
    "password": null,
    "old_password": null,
    "birthdate": null,
    "email_verified_at": null,
    "created_at": null,
    "updated_at": null,
    "deleted_at": null,
    "old_data": null,
    "devices": [
      {
        "updated_at": "2021-12-14T12:13:07.000000Z",
        "serial": "sr_32",
        "vendor": "folan",
        "created_at": "2021-12-14T12:13:07.000000Z",
        "model": "device_model",
        "id": 5,
        "device_app": {
          "device_id": 5,
          "updated_at": "2021-12-14T12:13:07.000000Z",
          "created_at": "2021-12-14T12:13:07.000000Z",
          "id": 5,
          "uuid": "32481b80-5cd7-11ec-ba02-c33a09f165eb"
        },
        "uuid": "3242f860-5cd7-11ec-9d54-c3339177d9bb"
      }
    ]
  }
}

我已經閱讀了更新檔案的檔案，但似乎沒有這種情況的例子。

uj5u.com熱心網友回復：

你需要的是這樣的：

POST index/_doc/20/_update
{
  "script": {
    "lang": "painless",
    "source": "ctx._source.devices.removeIf(device -> device.id == 'sr_31')"
  }
}
