FIWARE-IDAS：注册设备出现问题

我和IDAS探员有问题。使用MQTT Ultralight代理，取决于我注册设备的方式，当代理收到读取iotagent服务崩溃且上下文代理中的相关实体未更新时

正确的行为是下一个。如果要创建服务：

curl -X POST 172.21.0.23:8090/iot/services \
-i  \
-H "Content-Type: application/json" \
-H "Fiware-Service: red_entrada _1" \
-H "Fiware-ServicePath: /Prueba" \
-d '{
    "services": [
    {
        "apikey": "pass_1", 
        "cbroker": "http://172.21.0.23:1026", 
        "entity_type": "disp_entrada_1", 
        "resource": "/iot/mqtt"
    }]}'

。。。以及设备，用于建立传入属性和每个属性的名称：

curl -X POST 172.21.0.23:8090/iot/devices \
-i  \
-H "Content-Type: application/json" \
-H "Fiware-Service: red_entrada _1" \
-H "Fiware-ServicePath: /Prueba" \
-d '{
"devices":[
{
    "device_id": "AC_2", 
    "entity_name":"disp_entrada_1:AC_2",
    "protocol":"PDI-IoTA-MQTT-UltraLight", 
    "entity_type": "disp_entrada_1", 
    "timezone": "Europe/Madrid", 
    "attributes": [ 
    {
        "object_id": "LUX", 
        "name": "LUX_1", 
        "type": "string" 
    }, 
    { 
        "object_id": "LUM", 
        "name": "LUM_1",
        "type": "string" }, 
    { 
        "object_id": "HUMB", 
        "name": "HUMB_1", 
        "type": "string" 
    }, 
    { 
        "object_id": "TCB", 
        "name": "TCB_1", 
        "type": "string" 
    }, 
    { 
        "object_id": "IN_TEMP", 
        "name": "IN_TEMP_1", 
        "type": "string" }, 
    { 
        "object_id": "BAT", 
        "name": "BAT_1", 
        "type": "string" 
    } 
]}]}'

因此，将在上下文代理中创建一个新实体，当读数到达代理时，该实体将更新：

{
        "_id" : {
                "id" : "disp_entrada_1:AC_2",
                "type" : "disp_entrada_1",
                "servicePath" : "/Prueba"
        },
        "attrNames" : [
                "TimeInstant",
                "LUX_1",
                "LUM_1",
                "HUMB_1",
                "TCB_1",
                "IN_TEMP_1",
                "BAT_1"
        ],
        "attrs" : {

                        ],
                        "creDate" : 1457943103,

                                        "name" : "TimeInstant",
                                        "type" : "ISO8601",
                                        "value" : "2016-03-14T08:11:49.230590Z"
                                }
                        ],
                        "creDate" : 1457943103,
                        "modDate" : 1457943109
                }
        },
        "creDate" : 1457943015,
        "modDate" : 1457943109
}

当我注册一个新设备，并使用“object_id”的相同值（传入MQTT数据中的属性名称）作为属性名称时，问题就出现了。在这种情况下，当然不需要注册设备）。例如：

curl -X POST 172.21.0.23:8090/iot/devices \
-i  \
-H "Content-Type: application/json" \
-H "Fiware-Service: red_entrada_2" \
-H "Fiware-ServicePath: /Prueba" \
-d '{
"devices":[
{
    "device_id": "AC_2", 
    "entity_name":"disp_entrada_1:AC_2",
    "protocol":"PDI-IoTA-MQTT-UltraLight", 
    "entity_type": "disp_entrada_1", 
    "timezone": "Europe/Madrid", 
    "attributes": [ 
    { 
        "object_id": "LUX", 
        "name": "LUX", 
        "type": "string" 
    }, 
    { 
        "object_id": "LUM", 
        "name": "LUM", 
        "type": "string"
    },
    { 
        "object_id": "HUMB", 
        "name": "HUMB", 
        "type": "string" 
    }, 
    { 
        "object_id": "TCB", 
        "name": "TCB", 
        "type": "string" 
    }, 
    { 
        "object_id": "IN_TEMP", 
        "name": "IN_TEMP", 
        "type": "string" 
    }, 
    { 
        "object_id": "BAT", 
        "name": "BAT", 
        "type": "string" 
    } 
]}] }'    

在这种情况下，也会在上下文代理中创建一个新实体，但当读取数据到达时，实体不会更新，IoAgent服务崩溃。实体状态：

{
        "_id" : {
                "id" : " disp_entrada_1:AC_2",
                "type" : " disp_entrada_1",
                "servicePath" : "/Prueba"
        },
        "attrNames" : [
                "TimeInstant"
        ],
        "attrs" : {
                "TimeInstant" : {
                        "type" : "ISO8601",
                        "creDate" : 1457948167,
                        "modDate" : 1457948167,
                        "value" : "2016-03-14T09:36:07.432814Z"
                }
        },
        "creDate" : 1457948167,
        "modDate" : 1457948167
}

我看不出这种行为有什么逻辑。如果我没有事先注册设备，实体将自动创建，属性将以“object_id”字段的值作为名称（这是我在第二个示例中尝试做的）

？这可能是由于代理或管理器安装上的问题吗？

实际上这是一个错误，当您将要转换为相同（“t”）的参数“t”关联起来时，它会导致无限循环

最好的解决办法是不要求任何翻译，然后将其保留为原文（“t”）

在下一个版本中，此错误将被修复
