Fiware 物联网代理 Json 拒绝 POST 到 /v2/op/update

Question

我对 fiware IoT Agent 很感兴趣 JSON，并且我尝试解决了问题。我已经使用 this 教程安装了物联网代理 JSON。本教程涉及 IoT Actuator Connection 并检查我们必须 POST 到 {IoTAgentIP:Port}/v2/op/update 的连接。当我 post 到达此端点时，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 Post 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",
            "ring" : {
                "type": "command",
                "value": ""
            }
        }
    ]
}'

我的 IoT 代理版本是：

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

更新 - 使用最新版本的 IoTA 和 orion，我在 IoTA 日志文件中得到以下内容：

Answer 1

我设法让它与一个服务组 (/iot/d) 一起工作。因此 Post 附加传感器的请求来自 /iot/d 服务组。我使用 docker 图像（使用 docker compose 编译，如示例）。我还在 docker 文件中修改了 IOTA_DEFAULT_RESOURCE 以防万一： IOTA_DEFAULT_RESOURCE= 我用过最新的 IoT Agent JSON 1.15.0 和之前的 Orion 2.4.0 版本。
