如何使用golang从亚马逊S3存储桶子文件夹中获取对象列表？

import (
    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/s3"
)

sess, err := session.NewSession(&aws.Config{
    Region: aws.String("your_region"),
    Credentials: credentials.NewStaticCredentials("your_access_key_id", "your_secret_access_key", ""),
})
if err != nil {
    // 处理错误
}

svc := s3.New(sess)

input := &s3.ListObjectsV2Input{
    Bucket: aws.String("your_bucket_name"),
    Prefix: aws.String("your_folder_name/"),
}

result, err := svc.ListObjectsV2(input)
if err != nil {
    // 处理错误
}

for _, obj := range result.Contents {
    // 处理每个对象
    fmt.Println(*obj.Key)
}
