运行以下命令来创建代表你的自行车的东西，名为 Bike-1。有关如何使用创建事物的更多信息 Amazon CLI，请参阅通过参考创建事物Amazon CLI。

aws iot create-thing --thing-name "Bike-1" \
--attribute-payload '{"attributes": {"model":"OEM-2302-12", "battery":"35", "acqDate":"06/09/23"}}'

此命令的输出可能如下所示：

{
    "thingName": "Bike-1",
    "thingArn": "arn:aws:iot:us-east-1:123456789012:thing/Bike-1",
    "thingId": "df9cf01d-b0c8-48fe-a2e2-e16cff6b23df"
}

运行以下命令创建一个命名的阴影来存储 Bike-1 的位置数据（坐标 47.61564，-122.33584）。有关如何使用 Amazon CLI创建命名阴影的更多信息，请参阅 Reference 中的 update-thing-sh adow。Amazon CLI

aws iot-data update-thing-shadow \
--thing-name Bike-1 \
--shadow-name Bike1-shadow \
--cli-binary-format raw-in-base64-out \
--payload '{"state":{"reported":{"coordinates":{"lat": 47.6153, "lon": -122.3333}}}}' \
"output.txt" \

此命令不会生成任何输出。要查看你创建的命名阴影，你可以运行 list-nam ed-shadows-for-thing CL I 命令。

aws iot-data list-named-shadows-for-thing --thing-name Bike-1

此命令的输出可能如下所示：

{
    "results": [
        "Bike1-shadow"
    ],
    "timestamp": 1699574309
}

运行命令以更新位置索引的索引配置。

aws iot update-indexing-configuration --cli-input-json '{
"thingIndexingConfiguration": { "thingIndexingMode": "REGISTRY",
"thingConnectivityIndexingMode": "OFF",
"deviceDefenderIndexingMode": "OFF",
"namedShadowIndexingMode": "ON",
"filter": {
    "namedShadowNames": ["Bike1-shadow"],
    "geoLocations":[{
        "name":"shadow.name.Bike1-shadow.reported.coordinates"
    }]
},
"customFields": [
{ "name":"attributes.battery",
"type":"Number"}] } }'

命令不会生成任何输出。您可能需要稍等片刻，直到更新完成。要检查状态，请运行 desc ribe-index CLI 命令。如果你看到 sh indexStatus ows:ACTIVE，则你的事物索引更新已完成。

运行命令以验证您的索引配置。此为可选步骤。

aws iot get-indexing-configuration

输出可能如下所示：

{
    "thingIndexingConfiguration": {
        "thingIndexingMode": "REGISTRY",
        "thingConnectivityIndexingMode": "OFF",
        "deviceDefenderIndexingMode": "OFF",

            },

            },

                "type": "String"
            },
            {

                "type": "String"
            }
        ],
