我有一些麻烦从http://www.slideshare.net/FI-WARE/io-t-basicexercisesdevelopersweek获得预期的结果
注册新设备时没有问题，它的实体也在Orion CB上成功创建，但在查询创建的实体时，不显示设备属性 . Created Entity只有TimeInstant属性 .
我在发送观察时得到200响应代码，但由于缺少CB上的实体属性，它显然没有效果 .
Registering device
-
URL：/ iot / devices
-
方法：POST
-
有效载荷：
JSON
{
"devices": [
{
"device_id": "14:da:e9",
"entity_name": "Thing12",
"entity_type": "Thing12Type",
"protocol": "PDI-IoTA-UltraLight",
"timezone": "Europe/Madrid",
"attributes": [
{
"name": "weight",
"type": "double",
"object_id": "weight"
},
{
"name": "valid",
"type": "boolean",
"object_id": "valid"
}
]
}
]
}
Listing devices
-
URL：/ iot / devices / 14：da：e9

问题似乎出现在图像orion-psb-image-R4.2上 . 启动新实例（CentOS-6.3init）并手动安装每个组件后，问题似乎已解决 . 可能是之前实例中版本之间的冲突 .
只要发送与这些属性相关的观察结果，就会在ContextBroker中创建属性 . 只是尝试发送“权重”和“有效”的观察结果，您应该能够在ContextBroker相关实体上看到这些属性 .
如果这对您有用，请告诉我们 .
您为非创建设备观察到的行为是故意设计的，因此设备注册可能是可选的（尽管我们不建议这样做） .
感谢您使用IDAS！
