将多个实体更新到上下文代理

Upserting multiple entities to context broker

有没有办法在单个 http 请求中将多个实体更新到 Context Broker v2,例如在请求中提交数组?

我有这样的想法:

[POST] /v2/entities/?options=upsert

[
    {
        id: 'urn:ngsi-ld:xyz:123',
        type: 'xyz',
        ...
    },
    {
        id: 'urn:ngsi-ld:xyz:456',
        type: 'xyz',
        ...
    },
    ...
]

是的,使用 POST /v2/updateappend 操作类型。例如(取自NGSIv2 API walkthrough的例子):

POST /v2/op/update

{
  "actionType": "append",
  "entities": [
    {
      "type": "Room",
      "id": "Room3",
      "temperature": {
        "value": 21.2,
        "type": "Float"
      },
      "pressure": {
        "value": 722,
        "type": "Integer"
      }
    },
    {
      "type": "Room",
      "id": "Room4",
      "temperature": {
        "value": 31.8,
        "type": "Float"
      },
      "pressure": {
        "value": 712,
        "type": "Integer"
      }
    }
  ]
}

这将更新 Room3Room4 实体(如果它们以前存在)或创建它们(如果它们以前不存在)。
