`CreateThing`

以下代码示例演示如何使用 `CreateThing`。

------
#### [ .NET ]

**适用于 .NET 的 Amazon SDK (v4)**

```
    /// <summary>
    /// Creates an AWS IoT Thing.
    /// </summary>
    /// <param name="thingName">The name of the Thing to create.</param>
    /// <returns>The ARN of the Thing created, or null if creation failed.</returns>
    public async Task<string?> CreateThingAsync(string thingName)
    {
        try
        {
            var request = new CreateThingRequest
            {
                ThingName = thingName
            };

            var response = await _amazonIoT.CreateThingAsync(request);
            _logger.LogInformation($"Created Thing {thingName} with ARN {response.ThingArn}");
            return response.ThingArn;
        }
        catch (Amazon.IoT.Model.ResourceAlreadyExistsException ex)
        {
            _logger.LogWarning($"Thing {thingName} already exists: {ex.Message}");
            return null;
        }
        catch (Exception ex)
        {
            _logger.LogError($"Couldn't create Thing {thingName}. Here's why: {ex.Message}");

 还有更多相关信息 GitHub。在 [Amazon 代码示例存储库](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/cpp/example_code/iot#code-examples)中查找完整示例，了解如何进行设置和运行。

```
//! Create an AWS IoT thing.
/*!
  \param thingName: The name for the thing.
  \param clientConfiguration: AWS client configuration.
  \return bool: Function succeeded.
 */
bool AwsDoc::IoT::createThing(const Aws::String &thingName,
                              const Aws::Client::ClientConfiguration &clientConfiguration) {
    Aws::IoT::IoTClient iotClient(clientConfiguration);
    Aws::IoT::Model::CreateThingRequest createThingRequest;
    createThingRequest.SetThingName(thingName);

    Aws::IoT::Model::CreateThingOutcome outcome = iotClient.CreateThing(
            createThingRequest);
    if (outcome.IsSuccess()) {
        std::cout << "Successfully created thing " << thingName << std::endl;
    }
    else {
        std::cerr << "Failed to create thing " << thingName << ": " <<

#### [ CLI ]

**Amazon CLI**  
**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"
}
```
