Fiware Orion上下文代理和iotagentUL命令问题

提问于

2

我是Fiware用户，我在 Cloud 上的不同虚拟机中部署了猎户座上下文代理GE，cepheus GE和iotagent-ul实例 . 我在iot代理中注册了一个设备，在注册请求中指定了一个命令属性，并在注册过程中在上下文代理中创建了相应的实体 . 现在，当我使用其属性和命令属性及其名称和类型注册设备时，设备在iot代理上注册，并且其实体也在上下文代理中创建 . 但奇怪的是，命令属性只被转换为其特殊属性，即commandName_info和commandName_status，但命令属性本身并未在iot代理日志的注册结果中显示 . 此外，当我这样做时对Orion上下文代理中的命令属性执行更新操作时，无法识别该属性，并且更新失败，因为在权限本身中缺少命令属性 . 注册过程如下：

  • 这是我发送的注册请求：

（curl -v -H 'content-type: application/json' -H 'fiware-service: ourservicename' -H 'fiware-servicepath: /ourservicpath' -X POST'http://iotagentULaddress:8080/iot/devices'-d @ - ）<< EOF

{
"`devices`": [
    {
        "device_id": "controller12",
        "entity_name": "labcontroller12",
        "entity_type": "Controller",
        "isPattern" :"false",
        "protocol": "IoTA-UL",
        "timezone": "Egypt/Cairo",
        "endpoint": "http://iotagentULaddress:8080",
        "attributes": [
        {
            "object_id": "n",
            "name": "number",
            "type": "string"
        }],
        "commands": [{
            "name": "play",
            "type": "string"
        }]
    }]
}
EOF

这是iot代理的日志中的注册结果，显示注册实体及其在上下文代理中的创建方式：

现在很清楚，命令属性不是创建的，只是它的特殊属性描述了命令状态本身，但是没有要更新的命令 . 那么，我的注册请求是否正确组合以适应iotagen-ul实例，特别是对于命令的解释？我怎样才能验证注册的正确性？我只是想知道问题究竟在哪里 . 并非常感谢 .

    正如您在日志中看到的那样，您必须查询的命令将创建为Context Provider注册（对以下URL的请求“http://147.27.60.58:1026/NGSI9/registerContext”） . 命令属性未注册为NGSI属性，而是定义为另一个Context Provider（在本例中为IoTAgent）提供的属性 . 那是's why there is no mention of the command attribute in the request that creates the initial entity: it'的预期行为 .
