Method: Aws::S3::Client#delete_objects

Defined in:: lib/aws-sdk-s3/client.rb

#delete_objects(params = {}) ⇒ `Types::DeleteObjectsOutput`

This operation enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this operation provides a suitable alternative to sending individual delete requests, reducing per-request overhead.

The request contains a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete operation and returns the result of that delete, success, or failure, in the response. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted.

The operation supports two modes for the response: verbose and quiet. By default, the operation uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete operation encountered an error. For a successful deletion, the operation does not return any information about the delete in the response body.

When performing this operation on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see [ MFA Delete].

Finally, the Content-MD5 header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit.

Example: To delete multiple objects from a versioned bucket


# The following example deletes objects from a bucket. The bucket is versioned, and the request does not specify the
# object version to delete. In this case, all versions remain in the bucket and S3 adds a delete marker.

resp = client.delete_objects({
  bucket: "examplebucket", 
  delete: {
    objects: [
      {
        key: "objectkey1", 
      }, 
      {
        key: "objectkey2", 
      }, 
    ], 
    quiet: false, 
  }, 
})

resp.to_h outputs the following:
{
  deleted: [
    {
      delete_marker: true, 
      delete_marker_version_id: "A._w1z6EFiCF5uhtQMDal9JDkID9tQ7F", 
      key: "objectkey1", 
    }, 
    {
      delete_marker: true, 
      delete_marker_version_id: "iOd_ORxhkKe_e8G8_oSGxt2PjsCZKlkt", 
      key: "objectkey2", 
    }, 
  ], 
}

Example: To delete multiple object versions from a versioned bucket


# The following example deletes objects from a bucket. The request specifies object versions. S3 deletes specific object
# versions and returns the key and versions of deleted objects in the response.

resp = client.delete_objects({
  bucket: "examplebucket", 
  delete: {
    objects: [
      {
        key: "HappyFace.jpg", 
        version_id: "2LWg7lQLnY41.maGB5Z6SWW.dcq0vx7b", 
      }, 
      {
        key: "HappyFace.jpg", 
        version_id: "yoz3HB.ZhCS_tKVEmIOr7qYyyAaZSKVd", 
      }, 
    ], 
    quiet: false, 
  }, 
})

resp.to_h outputs the following:
{
  deleted: [
    {
      key: "HappyFace.jpg", 
      version_id: "yoz3HB.ZhCS_tKVEmIOr7qYyyAaZSKVd", 
    }, 
    {
      key: "HappyFace.jpg", 
      version_id: "2LWg7lQLnY41.maGB5Z6SWW.dcq0vx7b", 
    }, 
  ],

Parameters:

params (Hash) (defaults to: {}) —

({})

Options Hash (params):

:bucket (required, String) —

The bucket name containing the objects to delete.

When using this API with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this operation using an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see [Using Access Points] in the *Amazon Simple Storage Service Developer Guide*.

[1]: docs.aws.amazon.com/AmazonS3/latest/dev/using-access-points.html
:delete (required, Types::Delete) —

Container for the request.
:mfa (String) —

The concatenation of the authentication device’s serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.
:request_payer (String) —

Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from requester pays buckets, see [Downloading Objects in Requestor Pays Buckets] in the *Amazon S3 Developer Guide*.

[1]: docs.aws.amazon.com/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.html
:bypass_governance_retention (Boolean) —

Specifies whether you want to delete this object even if it has a Governance-type Object Lock in place. You must have sufficient permissions to perform this operation.

Returns:

(Types::DeleteObjectsOutput) —
Returns a response object which responds to the following methods:
- #deleted => Array<Types::DeletedObject>
- #request_charged => String
- #errors => Array<Types::Error>
