Fiware 向不存在的设备发送测量值时创建设备-IoTAgent UL

我们在物联网代理Ultralight中发现了一个bug

如果我们试图向一个不存在的设备发送测量值，我们将得到一个

404-未找到设备
错误，但同时将在IoTA和Orion CB的数据库中创建一个没有任何属性的设备

当我说没有任何属性的设备时，我指的是以下内容：

{
    "device_id": "test",
    "service": "MyService",
    "service_path": "/MyServicePath",
    "entity_name": "MyEntity:test",
    "entity_type": "MyEntity",
    "attributes": [],
    "lazy": [],
    "commands": [],
    "static_attributes": []
}

这是一个非常重要的bug，因为创建任意多的设备非常简单，可能会占用我们的数据库空间

有人知道怎么解决吗？

您使用的是哪一版本的IoAgent ul和外部组件（Fiware OCB和MongoDB）？强烈建议使用最新版本
这是使用docker映像运行OCB和MongoDB的好方法
你能给我们提供你用来发送测量数据的命令/代码吗

从我自己开始，我对它进行了测试，效果非常好：

Curl用于发送测量的命令：

#!/usr/local/bin
mosquitto_pub -t /TEF/sensor03/attrs -m 't|45|c|extreme'
