Object Storage Service:Transfer acceleration (Go SDK V2)

The following example creates an OSS client, builds a PutBucketTransferAccelerationRequest with Enabled set to true, and calls PutBucketTransferAcceleration to enable transfer acceleration for the specified bucket.

package main

import (
	"context"
	"flag"
	"log"

	"github.com/aliyun/alibabacloud-oss-go-sdk-v2/oss"
	"github.com/aliyun/alibabacloud-oss-go-sdk-v2/oss/credentials"
)

// Define global variables.
var (
	region     string // Region in which the bucket is located.
	bucketName string // Name of the bucket.
)

// Specify the init function used to initialize command line parameters.
func init() {
	flag.StringVar(&region, "region", "", "The region in which the bucket is located.")
	flag.StringVar(&bucketName, "bucket", "", "The name of the bucket.")
}

func main() {
	// Parse command line parameters.
	flag.Parse()

	// Check whether the name of the bucket is specified.
	if len(bucketName) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, bucket name required")
	}

	// Check whether the region is specified.
	if len(region) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, region required")
	}

	// Load the default configurations and specify the credential provider and region.
	cfg := oss.LoadDefaultConfig().
		WithCredentialsProvider(credentials.NewEnvironmentVariableCredentialsProvider()).
		WithRegion(region)

	// Create an OSS client.
	client := oss.NewClient(cfg)

	// Create a request to enable transfer acceleration for the bucket.
	request := &oss.PutBucketTransferAccelerationRequest{
		Bucket: oss.Ptr(bucketName), // Name of the bucket.
		TransferAccelerationConfiguration: &oss.TransferAccelerationConfiguration{
			Enabled: oss.Ptr(true), // Enable transfer acceleration.
		},
	}

	// Execute the request to enable transfer acceleration.
	result, err := client.PutBucketTransferAcceleration(context.TODO(), request)
	if err != nil {
		log.Fatalf("failed to put bucket transfer acceleration %v", err)
	}

	// Display the result.
	log.Printf("put bucket transfer acceleration result:%#v\n", result)
}

The following example calls GetBucketTransferAcceleration and prints the Enabled field from the returned TransferAccelerationConfiguration.

package main

// Define global variables.
var (
	region     string // Region in which the bucket is located.
	bucketName string // Name of the bucket.
)

// Specify the init function used to initialize command line parameters.
func init() {
	flag.StringVar(&region, "region", "", "The region in which the bucket is located.")
	flag.StringVar(&bucketName, "bucket", "", "The name of the bucket.")
}

func main() {
	// Parse command line parameters.
	flag.Parse()

	// Check whether the name of the bucket is specified.
	if len(bucketName) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, bucket name required")
	}

	// Check whether the region is specified.
	if len(region) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, region required")
	}

	// Load the default configurations and specify the credential provider and region.
	cfg := oss.LoadDefaultConfig().
		WithCredentialsProvider(credentials.NewEnvironmentVariableCredentialsProvider()).
		WithRegion(region)

	// Create an OSS client.
	client := oss.NewClient(cfg)

	// Create a query request for the transfer acceleration status of the bucket.
	request := &oss.GetBucketTransferAccelerationRequest{
		Bucket: oss.Ptr(bucketName), // The name of the bucket.
	}

	// Query the transfer acceleration status.
	result, err := client.GetBucketTransferAcceleration(context.TODO(), request)
	if err != nil {
		log.Fatalf("failed to get bucket transfer acceleration %v", err)
	}

	// Display the transfer acceleration status of the bucket.
	log.Printf("get bucket transfer acceleration result:%#v\n", result.TransferAccelerationConfiguration.Enabled)
}
