Object Storage Service:Get vector bucket information (Go SDK V2)

Prerequisites

Before you begin, ensure that you have:

• The OSS Go SDK V2 installed

• The oss:GetVectorBucket permission granted via a RAM Policy or a bucket policy

• AccessKey credentials available as environment variables

By default, an Alibaba Cloud account has full permissions. A Resource Access Management (RAM) user or RAM role has no permissions by default and must be explicitly granted oss:GetVectorBucket.

Method definition

func (c *VectorsClient) GetVectorBucket(ctx context.Context, request *GetVectorBucketRequest, optFns ...func(*Options)) (*GetVectorBucketResult, error)

Sample code

The example below loads credentials from environment variables, builds a VectorsClient, and calls GetVectorBucket with the bucket name, region, and account ID passed as command-line flags.

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

var (
	region     string
	bucketName string
	accountId  string
)

func init() {
	flag.StringVar(&region, "region", "", "The region in which the vector bucket is located.")
	flag.StringVar(&bucketName, "bucket", "", "The name of the vector bucket.")
	flag.StringVar(&accountId, "account-id", "", "The ID of the vector account.")
}

func main() {
	flag.Parse()
	if len(bucketName) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, bucket name required")
	}

	if len(region) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, region required")
	}

	if len(accountId) == 0 {
		flag.PrintDefaults()
		log.Fatalf("invalid parameters, accounId required")
	}

	cfg := oss.LoadDefaultConfig().
		WithCredentialsProvider(credentials.NewEnvironmentVariableCredentialsProvider()).
		WithRegion(region).WithAccountId(accountId)

	client := vectors.NewVectorsClient(cfg)

	request := &vectors.GetVectorBucketRequest{
		Bucket: oss.Ptr(bucketName),
	}
	result, err := client.GetVectorBucket(context.TODO(), request)
	if err != nil {
		log.Fatalf("failed to get vector bucket %v", err)
	}
	log.Printf("get vector bucket result:%#v\n", result)
}

Run the example with:

go run main.go --region <region-id> --bucket <bucket-name> --account-id <account-id>
