Question

我正在尝试使用适用于Ruby的AWS开发工具包在Rails应用程序中执行某些S3上载，下载和删除操作。上传和下载工作正常;删除不是那么多。我无休止地用谷歌搜索了几个＆＃34;解决方案，＆＃34;但它们都没有真正起作用。

我尝试了几种尝试＃1的变种。我尝试了delete_objects，尝试传入数组和散列而不是单个对象名，尝试传入key：object name等。

尝试＃1：

def delete_file
  access_key_id = Rails.configuration.app['access_key_id']
  secret_access_key = Rails.configuration.app['secret_access_key']
  credentials = Aws::Credentials.new(access_key_id, secret_access_key)
  Aws.config[:credentials] = credentials
  s3_client = Aws::S3::Client.new(region: Rails.configuration.app['s3_region'], credentials: credentials)
  s3_resource = Aws::S3::Resource.new(client: s3_client)
  bucket = s3_resource.bucket(Rails.configuration.app['s3_bucket'])
  obj = s3_resource.bucket(Rails.configuration.app['s3_bucket']).object(object_name)
  s3_response = obj.delete
  Rails.logger.error("XXX")
  Rails.logger.error(s3_response)
  Rails.logger.error("XXX")
  return s3_response
end

输出：

XXX
#<struct Aws::S3::Types::DeleteObjectOutput delete_marker=true, version_id="null", request_charged=nil>
XXX

尝试＃2：

def delete_file
    access_key_id = Rails.configuration.app['access_key_id']
    secret_access_key = Rails.configuration.app['secret_access_key']
    credentials = Aws::Credentials.new(access_key_id, secret_access_key)
    Aws.config[:credentials] = credentials
    s3_client = Aws::S3::Client.new(region: Rails.configuration.app['s3_region'], credentials: credentials)
    s3_resource = Aws::S3::Resource.new(client: s3_client)
    bucket = s3_resource.bucket(Rails.configuration.app['s3_bucket'])
    s3_response = bucket.delete_objects({
      delete: {
        objects: [
          {
            key: object_name
          }
        ]
      }
    })
    Rails.logger.error("XXX")
    Rails.logger.error(s3_response)
    Rails.logger.error("XXX")
    return s3_response
end

输出：

XXX
#<struct Aws::S3::Types::DeleteObjectsOutput deleted=[#<struct Aws::S3::Types::DeletedObject key="[object_name]?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=[stuff]%2F20170813%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20170813T164341Z&X-Amz-Expires=3600&X-Amz-SignedHeaders=host&X-Amz-Signature=[stuff]", version_id=nil, delete_marker=true, delete_marker_version_id="null">], request_charged=nil, errors=[]>
XXX

请注意，我使用的S3存储桶已关闭版本控制，因此只会有一个版本的上传文件。我想从给定的存储桶中完全删除给定的对象名称。

我正在寻找一种以编程方式在Rails 5.1中执行此操作的方法。谢谢，全部。

编辑：两次尝试不起作用 - 与尝试＃1相同的输出：

s3_response = s3_client.delete_object({
    bucket: Rails.configuration.app['s3_bucket'],
    key: object_name
})

s3_response = s3_client.delete_object({
    bucket: Rails.configuration.app['s3_bucket'],
    key: full_object_url
})

Answer 1

您在代码中定义object_name的位置？此外，如果您只需要与S3存储桶进行交互，我建议您使用更简单的gem：https://github.com/qoobaa/s3
