订阅会检测实体的创建和更新,但不会检测到实体的移除。

  • 创建订阅:

POST http://myhost:orion_port/v2/subscriptions

{
    "description": "Send a notification to detect any change",
    "subject": {
        "entities": [{
            "idPattern": ".*"
        }]
    },
    "notification": {
        "http": {
            "url": "http://myhost:myport/myendpoint"
        }
    }
}
  • 创建实体:

POST http://myhost:iot_aget_json_port/iot/devices

{
    "devices": [{
        "device_id": "entity_test_agent",
        "entity_name": "entity_test_orion",
        "entity_type": "test",
        "transport": "HTTP",
        "protocol": "IoTA-JSON",
        "attributes": [{
             "object_id": "status",
             "name": "status",
             "type": "Text"
        }],
        "static_attributes": [{
             "name": "name",
             "type": "Text",
             "value": "Test"
        }]
    }]

}

  • 实体更新:

输入http://myhost:orion_port/v2/entities/entity_test_orion/attrs/name

{
     "value": true
}
  • 删除实体:

删除http://myhost:orion_port/v2/entities/entity_test_orion

删除http://myhost:iot_aget_json_port/iot/devices/entity_test_agent

首先,我发送订阅创建以检测实体中的更改。

此后,我创建了一个实体,并且订阅得以顺利执行。然后,我更新了实体名称,并再次完美地收到了预订,但是如果删除实体,我将不会收到任何事件。

有什么方法可以接收订阅事件以检测何时删除实体?

很遗憾,没有订阅处理删除事件
