Fiware IotAgent：无法向设备发送命令

标签： fiware fiware-orion

我在物联网代理中认可了我的设备：

curl -X POST http://192.168.1.110:80/iot/devices \
-i \
-H "Content-Type: application/json" \
-H "Fiware-Service: egmsmartcity" \
-H "Fiware-ServicePath: /egmsmartcitypath" \
-d ' { "devices": [ { "device_id": "test",
 "entity_name": "sensors:test",
 "entity_type": "sensors",
"protocol": "PDI-IoTA-MQTT-UltraLight",
 "timezone": "Europe/Paris",
 "endpoint": "notUsed",
 "commands": [{ "name": "ping", "type": "command", "value": ""}]  } ] }'

在上下文Broker中注册成功：

获取：http://192.168.1.77:1026/v1/contextEntities/sensors:test

带标题的

：

Accept: application/json
Fiware-Service: egmsmartcity
Fiware-ServicePath: /egmsmartcitypath

我收到了以下回复：

{
contextElement: {
type: "sensors"
isPattern: "false"
id: "sensors:test"
attributes: [1]
0:  {
name: "TimeInstant"
type: "ISO8601"
value: "2015-11-30T16:53:45.556269Z"
}-
-
}-
statusCode: {
code: "200"
reasonPhrase: "OK"
}-
}

然后当我尝试像这样更新命令时：

curl -X POST http://192.168.1.77:1026/v1/updateContext \
     -i \
-H "Content-Type: application/json" \
-H "Fiware-Service: egmsmartcity" \
-H "Fiware-ServicePath: /egmsmartcitypath" \
-d ' {"updateAction":"UPDATE","contextElements":[{"id":"sensors:test","type":"sensors","isPattern":"false","attributes":[{"name":"ping","type":"command","value":"22" } ]} ]}'

我收到了这个回复：

HTTP/1.1 200 OK
Content-Length: 157
Content-Type: application/xml
Date: Mon, 30 Nov 2015 17:05:11 GMT

<updateContextResponse>
  <errorCode>
    <code>404</code>
    <reasonPhrase>No context element found</reasonPhrase>
  </errorCode>
</updateContextResponse>

为什么返回“没有找到上下文元素”？我错过了什么？ 在此先感谢您的帮助！

[更新] 我试过一个简单的上传“/ iot / devices” 这是Iot Agent lg文件中的日志：

如果操作成功，则从localhost

似乎iot代理在终止请求处理之前完成操作

1 个答案:

答案 0 :(得分：1)

似乎IoT代理无法回答updateContext请求。将属性声明为命令时，IoT代理会将自身注册为Context Broker中Device实体的该属性的Context Provider。如果UPDATE请求到达CB的该属性，该请求将被转发到IoTA。如果IoTA无法应答或未找到，则请求将失败。

此问题的可能原因是公共IP的配置错误。如果Context Broker无法找到您要更新的属性的提供程序，则会返回404错误。您是否在IoT代理中配置了公共IP？
