示例 1：在注册表中创建事物记录

以下create-thing示例在 Amazon IoT 事物注册表中为设备创建条目。

aws iot create-thing \
    --thing-name SampleIoTThing

输出：

{
    "thingName": "SampleIoTThing",
    "thingArn": "arn:aws:iot:us-west-2: 123456789012:thing/SampleIoTThing",
    "thingId": " EXAMPLE1-90ab-cdef-fedc-ba987EXAMPLE "
}

示例 2：定义与事物类型关联的事物

以下 create-thing 示例创建了一个事物，该事物具有指定事物类型及其属性。

aws iot create-thing \
    --thing-name "MyLightBulb" \
    --thing-type-name "LightBulb" \
    --attribute-payload "{"attributes": {"wattage":"75", "model":"123"}}"

输出：

{
    "thingName": "MyLightBulb",
    "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/MyLightBulb",
    "thingId": "40da2e73-c6af-406e-b415-15acae538797"
}
