Fiware IoT代理Json拒绝发布到/ v2 / op / update

如何解决Fiware IoT代理Json拒绝发布到/ v2 / op / update

我对fiware IoT Agent JSON感兴趣，我试图解决问题。我想使用this教程来安装IoT Agent JSON。本教程介绍了IoT执行器连接，要检查连接，我们必须POST到{IoTAgentIP：Port} / v2 / op / update。当我发布到该端点时，我得到：

<html lang="en">

<head>
   <Meta charset="utf-8">
   <title>Error</title>
</head>

<body>
   <pre>Cannot POST /v2/op/update</pre>
</body>

</html>

我的发布命令是：

curl -iX POST \
  http://localhost:4041/v2/op/update \
  -H 'Content-Type: application/json' \
  -H 'fiware-service: openiot' \
  -H 'fiware-servicepath: /' \
  -d '{
    "actionType": "update","entities": [
        {
            "type": "Alarm","id": "urn:ngsi-ld:Alarm:001","ring" : {
                "type": "command","value": ""
            }
        }
    ]
}'

和

curl -iX POST \
  http://localhost:4041/v2/op/update \
  -H 'Content-Type: application/json' \
  -H 'fiware-service: openiot' \
  -H 'fiware-servicepath: /' \
  -d '{
    "actionType": "update","entities": [
        {
            "type": "Bell","id": "urn:ngsi-ld:Bell:001","value": ""
            }
        }
    ]
}'

我的IoT代理版本为：

{
    "libVersion": "2.12.0-next","port": 4041,"baseRoot": "/","version": "1.14.0-next"
}

更新-使用IoTA和Orion的最新版本，我在以下IoTA日志文件中获得了

解决方法

我设法使其可以与一个服务组（/ iot / d）一起使用。因此，Post附加传感器的请求来自/ iot / d服务组。我使用docker映像（与docker compose编译，如示例所示）。我还在docker文件中修改了IOTA_DEFAULT_RESOURCE，以防万一： IOTA_DEFAULT_RESOURCE= 我使用了最新的IoT Agent JSON 1.15.0和以前的Orion版本2.4.0。
