上下文代理忽略值、fiware orion 和 iotagent

Question

猎户座版本：2.3.0 iotagent-ul 版本：1.12.0

我在 mqtt 上使用 fiware 和 iotagent。我想向一些具有不同值的设备发送命令。我已经关注 https://github.com/FIWARE/tutorials.IoT-over-MQTT 并阅读了一些文档。在提供服务组（使用 apikey：123456）和执行器之后，我可以按照 iota URL :

发送带有值的命令

curl -iX POST \                       
  'http://localhost:4041/iot/devices' \
  -H 'Content-Type: application/json' \
  -H 'fiware-service: openiot' \
  -H 'fiware-servicepath: /' \
  -d '{
  "devices": [
    {
      "device_id": "dev001",
      "entity_name": "urn:ngsi-ld:Device:001",
      "entity_type": "Device",
      "protocol": "PDI-IoTA-UltraLight",
      "transport": "MQTT",
      "commands": [
        {"name": "date","type": "command", "value": {"hour": 9, "minute": 31, "second": 0}}
       ]
    }
  ]
}
'

iota 将 mqtt 消息发布到：/123456/dev001/cmd 有效载荷 dev001@date|hour=9|minute=31|second=0

但是当使用上下文代理时，该值被忽略：

curl -iX PATCH \                                 
  'http://localhost:1026/v2/entities/urn:ngsi-ld:Device:001/attrs' \
  -H 'Content-Type: application/json' \
  -H 'fiware-service: openiot' \
  -H 'fiware-servicepath: /' \
  -d '{
  "date": {            
      "type" : "command",
      "value" : {"hour": 9, "minute": 31, "second": 0}     
  }                                                                            
}'

在这里，iota 发布一条 mqtt 消息到：/123456/dev001/cmd 有效载荷 dev001@date|

为什么会被忽略？我做错了什么吗？

抱歉我的英语不好。

Answer 1

我找到了一个解决方案...在 url 中添加类型使上下文考虑值...很奇怪。

最后的url必须是：

curl -iX PATCH \                                 
  'http://localhost:1026/v2/entities/urn:ngsi-ld:Device:001/attrs?type=Device' \
  -H 'Content-Type: application/json' \
  -H 'fiware-service: openiot' \
  -H 'fiware-servicepath: /' \
  -d '{
  "date": {            
      "type" : "command",
      "value" : {"hour": 9, "minute": 31, "second": 0}     
  }                                                                            
}'

知道解决方案后，我试图理解问题并发现了这个问题：https://github.com/telefonicaid/fiware-orion/issues/3647

According to CPrs and request forwarding documentation

On forwarding, any type of entity in the NGSIv2 update/query matches registrations without entity type. However, the opposite doesn't work, so if you have registrations with types, then you must use ?type in NGSIv2 update/query in order to obtain a match. Otherwise you may encounter problems, like the one described in this post at Whosebug.
