How to manage OSS access point level block public access using OSS SDK for Go V2 - Object Storage Service

En este tema se describe cómo gestionar las configuraciones de bloqueo de acceso público a nivel de access point mediante OSS SDK for Go V2.

Notas

El código de ejemplo de este tema utiliza el identificador de región cn-hangzhou, que corresponde a la región China (Hangzhou). De forma predeterminada, se usa el endpoint público para acceder a los recursos de un bucket. Si necesita acceder a los recursos del bucket desde otros servicios de Alibaba Cloud ubicados en la misma región, utilice un endpoint interno. Para obtener más información sobre las regiones y los endpoints compatibles con Object Storage Service (OSS), consulte OSS regions and endpoints.
En este tema, las credenciales de acceso se obtienen de variables de entorno. Para obtener más información sobre cómo configurar las credenciales de acceso, consulte Configure access credentials (Go SDK V1).

Código de ejemplo

Habilitar el bloqueo de acceso público para un access point

A continuación se muestra un ejemplo de cómo habilitar el bloqueo de acceso público para un access point.

package main

import (
	"context" 
	"flag"    
	"log"    

	"github.com/aliyun/alibabacloud-oss-go-sdk-v2/oss"           // Import the OSS SDK package.
	"github.com/aliyun/alibabacloud-oss-go-sdk-v2/oss/credentials" // Import the package for processing authentication information.
)

var (
	region     string // Define a variable to store the region information obtained from the command line.
	bucketName string // Define a variable to store the bucket name obtained from the command line.
)
 
func init() {
	// Set the command line parameter to specify the region. This parameter is left empty by default.
	flag.StringVar(&region, "region", "", "The region in which the bucket is located.")
	// Set the command line parameter to specify the name of the bucket. This parameter is left empty by default.
	flag.StringVar(&bucketName, "bucket", "", "The name of the bucket.")
}

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

	// Define the access point name, which is hardcoded as "access point name" in this example. In actual scenarios, this value should be set according to the actual business requirements or passed through command line parameters.
	var accessPointName = "access point name"

	// Check if the name of the bucket is specified. If not, the program prints an error message indicating that this parameter is required and terminates.
	if len(bucketName) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, bucket name required") // Log the error message and terminate the program.
	}

	// Check if the region information is provided. If not, the program prints an error message indicating that this parameter is required and terminates.
	if len(region) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, region required") // Log the error message and terminate the program.
	}

	// Create a configuration object, load the credential provider from environment variables and specify the region.
	cfg := oss.LoadDefaultConfig().
		WithCredentialsProvider(credentials.NewEnvironmentVariableCredentialsProvider()).
		WithRegion(region)

	client := oss.NewClient(cfg) // Create a new OSS client instance using the configurations.

	// Create a PutAccessPointPublicAccessBlock request to configure block public access settings for a specific access point.
	request := &oss.PutAccessPointPublicAccessBlockRequest{
		Bucket:          oss.Ptr(bucketName), // Specify the name of the bucket.
		AccessPointName: oss.Ptr(accessPointName), // Specify the name of the access point.
		PublicAccessBlockConfiguration: &oss.PublicAccessBlockConfiguration{
			oss.Ptr(true), // Enable block public access.
		},
	}
	putResult, err := client.PutAccessPointPublicAccessBlock(context.TODO(), request) // Send the request to configure block public access settings for the access point.
	if err != nil {
		log.Fatalf("failed to put access point public access block %v", err) // If an error occurs, record the error message and exit.
	}

	log.Printf("put access point public access block result:%#v\n", putResult) // Display the result.
}
