Alibaba Cloud SDK:Configurar um período de timeout

No Alibaba Cloud SDK V1.0 for Go, é possível configurar períodos de timeout para solicitações de conexão e leitura em diferentes níveis, desde requisições individuais até padrões globais.

Métodos

• Utilize as configurações padrão. O timeout de conexão padrão é de 5.000 milissegundos e o timeout de leitura padrão é de 10.000 milissegundos.

  Importante

  A biblioteca principal do Alibaba Cloud SDK for Go inclui valores predefinidos de timeout de leitura para algumas operações de API. Quando existe um valor predefinido, ele tem precedência sobre o padrão global. Para mais informações, consulte api_timeout.go.

• Use um objeto de requisição. Esta configuração se aplica apenas à requisição atual.

  import (
  	"fmt"
  	"os"
  	"time"
  
  	"github.com/aliyun/alibaba-cloud-sdk-go/sdk"
  	"github.com/aliyun/alibaba-cloud-sdk-go/sdk/auth/credentials"
  	ecs "github.com/aliyun/alibaba-cloud-sdk-go/services/ecs"
  )
  
  func main() {
  	config := sdk.NewConfig()
  	// Use the AccessKey ID and AccessKey secret of the Resource Access Management (RAM) user.
  	credential := credentials.NewAccessKeyCredential(os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"), os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"))
  	client, err := ecs.NewClientWithOptions("cn-hangzhou", config, credential)
  	if err != nil {
  		panic(err)
  	}
  
  	// Create a request.
  	request := ecs.CreateDescribeRegionsRequest()
  	// Configure a timeout period for the request. This setting takes effect only for the current request.
  	request.SetConnectTimeout(10 * time.Second)
  	request.SetReadTimeout(5 * time.Second)
  	// Specify HTTPS as the protocol.
  	request.Scheme = "https"
  	// The request parameters.
  	request.InstanceChargeType = "PrePaid" // The billing method of the instance.
  	request.ResourceType = "instance"      // The resource type.
  	// Send the request and obtain a response.
  	response, err := client.DescribeRegions(request)
  	if err != nil {
  		fmt.Print(err.Error())
  	}
  	fmt.Printf("response is %#v\n", response)
  }

• Inicialize um cliente do SDK. Essa definição vale para todas as requisições enviadas por meio desse cliente.

  import (
  	"fmt"
  	"os"
  	"time"
  
  	"github.com/aliyun/alibaba-cloud-sdk-go/sdk"
  	"github.com/aliyun/alibaba-cloud-sdk-go/sdk/auth/credentials"
  	ecs "github.com/aliyun/alibaba-cloud-sdk-go/services/ecs"
  )
  
  func main() {
  	config := sdk.NewConfig()
  	// Use the AccessKey ID and AccessKey secret of the RAM user.
  	credential := credentials.NewAccessKeyCredential(os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"), os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"))
  	client, err := ecs.NewClientWithOptions("cn-hangzhou", config, credential)
  	if err != nil {
  		panic(err)
  	}
  	// Configure a timeout period on the SDK client. This setting takes effect on all requests that are sent by using the SDK client.
  	client.SetConnectTimeout(10 * time.Second)
  	client.SetReadTimeout(5 * time.Second)
  
  	// Create a request.
  	request := ecs.CreateDescribeRegionsRequest()
  	// Specify HTTPS as the protocol.
  	request.Scheme = "https"
  	// The request parameters.
  	request.InstanceChargeType = "PrePaid" // The billing method of the instance.
  	request.ResourceType = "instance"      // The resource type.
  	// Send the request and obtain a response.
  	response, err := client.DescribeRegions(request)
  	if err != nil {
  		fmt.Print(err.Error())
  	}
  	fmt.Printf("response is %#v\n", response)
  }

• Especifique um objeto Config ao inicializar o cliente do SDK. Os parâmetros definidos afetam todos os clientes inicializados com esse objeto.

  import (
  	"fmt"
  	"os"
  	"time"
  
  	"github.com/aliyun/alibaba-cloud-sdk-go/sdk"
  	"github.com/aliyun/alibaba-cloud-sdk-go/sdk/auth/credentials"
  	ecs "github.com/aliyun/alibaba-cloud-sdk-go/services/ecs"
  )
  
  func main() {
  	config := sdk.NewConfig()
  	// Use a Config object to configure a timeout period.
  	config.Timeout = 5 * time.Second
  	// Use the AccessKey ID and AccessKey secret of the RAM user.
  	credential := credentials.NewAccessKeyCredential(os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"), os.Getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"))
  	client, err := ecs.NewClientWithOptions("cn-hangzhou", config, credential)
  	if err != nil {
  		panic(err)
  	}
  
  	// Create a request.
  	request := ecs.CreateDescribeRegionsRequest()
  	// Specify HTTPS as the protocol.
  	request.Scheme = "https"
  	// The request parameters.
  	request.InstanceChargeType = "PrePaid" // The billing method of the instance.
  	request.ResourceType = "instance"      // The resource type.
  	// Send the request and obtain a response.
  	response, err := client.DescribeRegions(request)
  	if err != nil {
  		fmt.Print(err.Error())
  	}
  	fmt.Printf("response is %#v\n", response)
  }
