Parámetros específicos de la operación

La forma de pasar un parámetro de solicitud depende de los metadatos de la operación de la API. Por ejemplo, la operación DescribeInstanceStatus se define como {"name":"RegionId","in":"query",...}} en los metadatos. En este caso, "in":"query" indica que el identificador de región (RegionId) debe pasarse en QueryParams["key"] = "value".

        // 2. Create a CommonRequest object and configure the basic information about and request parameters of the API operation. 
        request := requests.NewCommonRequest()
        // 2.1 Configure the basic information about the API operation
	request.Domain = "ecs-cn-hangzhou.aliyuncs.com" // The endpoint of the API.
	request.Version = "2014-05-26" // The version number of the API.
	request.ApiName = "DescribeInstanceStatus" // The name of the API operation. When you call an RPC-style API operation, you must configure ApiName() to specify the name of the API operation.
	request.Method = "POST" // The request method. 
	request.Scheme = "https" // The request protocol. Valid values: HTTP and HTTPS. We recommend that you use HTTPS. 
	// request.PathPattern = "/"   // The resource path, which is required by ROA-style API operations. Do not configure this parameter for RPC-style API operations. 

        // 2.2 Configure the request parameters.
	// Scenario 1: Configure the query parameters in the format of QueryParams["key"] = "value".
	instanceIds := []string{
		"i-bp1axhql4dqXXXXXXXX",
		"i-bp124uve8zqXXXXXXXX",
	}
	request.QueryParams["RegionId"] = "cn-hangzhou"
	for i, id := range instanceIds {
	request.QueryParams[fmt.Sprintf("InstanceId.%d", i+1)] = id
	}

	// Scenario 2: Configure the body parameters in the format of FormParams["key"] = "value".
	// request.FormParams["key1"] = "value1"
	// request.FormParams["key2"] = "value2"
	// request.FormParams["key3"] = "value3"

// Initiate a request.

		panic(err)

Preguntas frecuentes

¿Qué debo hacer si aparece el mensaje de error "SDK.ServerError MissingParameter The input parameter "AccessKeyId" that is mandatory for processing this request is not supplied"?

Causa: el AccessKey pair no se configuró correctamente.

Soluciones:

1. Ejecute los comandos a continuación para comprobar si las variables de entorno ALIBABA_CLOUD_ACCESS_KEY_ID y ALIBABA_CLOUD_ACCESS_KEY_SECRET están configuradas.

   Linux/macOS

   echo $ALIBABA_CLOUD_ACCESS_KEY_ID
   echo $ALIBABA_CLOUD_ACCESS_KEY_SECRET

   Windows

   echo %ALIBABA_CLOUD_ACCESS_KEY_ID%
   echo %ALIBABA_CLOUD_ACCESS_KEY_SECRET%

   Si se devuelve un AccessKey pair válido, las variables de entorno están configuradas correctamente. Si no se devuelve ningún AccessKey pair o el devuelto no es válido, configure las variables de entorno según corresponda. Para obtener más información, consulte Configure environment variables in Linux, macOS, and Windows.

2. Revise el código en busca de errores relacionados con el AccessKey pair.

   Ejemplo de solicitud con error:

   client, err := sdk.NewClientWithAccessKey("<RegionId>",
   		os.Getenv("yourAccessKeyID"),
   		os.Getenv("yourAccessKeySecret"))
   	if err != nil {
   		panic(err)
   	}

   Nota

   En el ejemplo anterior, las cadenas literales que se pasan a os.Getenv() no coinciden con los nombres reales de las variables de entorno. Una vez que configure las variables de entorno como ALIBABA_CLOUD_ACCESS_KEY_ID y ALIBABA_CLOUD_ACCESS_KEY_SECRET en su computadora, os.Getenv leerá los valores correctos.

   Ejemplo de solicitud exitosa:

   client, err := sdk.NewClientWithAccessKey("<RegionId>",
   		os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"),
   		os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"))
   	if err != nil {
   		panic(err)
   	}
