AWS SDK 现在BatchDeleteIterator可以完成这项工作。通过亚马逊文档提供的示例。

package main

import (
    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/s3"
    "github.com/aws/aws-sdk-go/service/s3/s3manager"

    "fmt"
    "os"
)

//    go run s3_delete_objects BUCKET

func main() {
    if len(os.Args) != 2 {
        exitErrorf("Bucket name required\nUsage: %s BUCKET", os.Args[0])
    }

    bucket := os.Args[1]

    // Initialize a session in us-west-2 that the SDK will use to load
    // credentials from the shared credentials file ~/.aws/credentials.
    sess, _ := session.NewSession(&aws.Config{
        Region: aws.String("us-west-2")},
    )

    // Create S3 service client
    svc := s3.New(sess)

    // Setup BatchDeleteIterator to iterate through a list of objects.
    iter := s3manager.NewDeleteListIterator(svc, &s3.ListObjectsInput{
        Bucket: aws.String(bucket),
    })

    // Traverse iterator deleting each object
    if err := s3manager.NewBatchDeleteWithClient(svc).Delete(aws.BackgroundContext(), iter); err != nil {
        exitErrorf("Unable to delete objects from bucket %q, %v", bucket, err)
    }

    fmt.Printf("Deleted object(s) from bucket: %s", bucket)
}

func exitErrorf(msg string, args ...interface{}) {
    fmt.Fprintf(os.Stderr, msg+"\n", args...)
    os.Exit(1)
}
