Removes an object from a bucket. The behavior depends on the bucket's versioning state:
If bucket versioning is not enabled, the operation permanently deletes the object.
If bucket versioning is enabled, the operation inserts a delete marker, which becomes
the current version of the object. To permanently delete an object in a versioned
bucket, you must include the object’s versionId in the request. For more information
about versioning-enabled buckets, see Deleting
object versions from a versioning-enabled bucket.
If bucket versioning is suspended, the operation removes the object that has a null
versionId, if there is one, and inserts a delete marker that becomes the current
version of the object. If there isn't an object with a null versionId, and
all versions of the object have a versionId, Amazon S3 does not remove the
object and only inserts a delete marker. To permanently delete an object that has
a versionId, you must include the object’s versionId in the request.
For more information about versioning-suspended buckets, see Deleting
objects from versioning-suspended buckets.
Directory buckets - S3 Versioning isn't enabled and supported for directory
buckets. For this API operation, only the null value of the version ID is supported
by directory buckets. You can only specify null to the versionId query
parameter in the request.
Directory buckets - For directory buckets, you must make requests for this
API operation to the Zonal endpoint. These endpoints support virtual-hosted-style
requests in the format https://bucket-name.s3express-zone-id.region-code.amazonaws.com/key-name. Path-style requests are not supported. For more information about endpoints
in Availability Zones, see Regional
and Zonal endpoints for directory buckets in Availability Zones in the Amazon
S3 User Guide. For more information about endpoints in Local Zones, see Available
Local Zone for directory buckets in the Amazon S3 User Guide.
To remove a specific version, you must use the versionId query parameter. Using
this query parameter permanently deletes the version. If the object deleted is a delete
marker, Amazon S3 sets the response header x-amz-delete-marker to true.
If the object you want to delete is in a bucket where the bucket versioning configuration
is MFA Delete enabled, you must include the x-amz-mfa request header in the
DELETE versionId request. Requests that include x-amz-mfa must use HTTPS.
For more information about MFA Delete, see Using
MFA Delete in the Amazon S3 User Guide. To see sample requests that use
versioning, see Sample
Request.
Directory buckets - MFA delete is not supported by directory buckets.
You can delete objects by explicitly calling DELETE Object or calling (PutBucketLifecycle)
to enable Amazon S3 to remove them for you. If you want to block users or accounts
from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject,
s3:DeleteObjectVersion, and s3:PutLifeCycleConfiguration actions.
Directory buckets - S3 Lifecycle is not supported by directory buckets.
General purpose bucket permissions - The following permissions are required
in your policies when your DeleteObjects request includes specific headers.
s3:DeleteObject - To delete an object from a bucket, you must always
have the s3:DeleteObject permission.
s3:DeleteObjectVersion - To delete a specific version of an object
from a versioning-enabled bucket, you must have the s3:DeleteObjectVersion
permission.
Directory bucket permissions - To grant access to this API operation on a
directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically,
you grant the s3express:CreateSession permission to the directory bucket in
a bucket policy or an IAM identity-based policy. Then, you make the CreateSession
API call on the bucket to obtain a session token. With the session token in your request
header, you can make API requests to this operation. After the session token expires,
you make another CreateSession API call to generate a new session token for
use. Amazon Web Services CLI or SDKs create session and refresh the session token
automatically to avoid service interruptions when a session expires. For more information
about authorization, see CreateSession.
Directory buckets - The HTTP Host header syntax is Bucket-name.s3express-zone-id.region-code.amazonaws.com.
The following action is related to DeleteObject:
For .NET Core this operation is only available in asynchronous form. Please refer to DeleteObjectAsync.
Namespace: Amazon.S3
Assembly: AWSSDK.S3.dll
Version: 3.x.y.z
public abstract DeleteObjectResponse DeleteObject( String bucketName, String key )
The bucket name of the bucket containing the object. Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket-name.s3express-zone-id.region-code.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Zone (Availability Zone or Local Zone). Bucket names must follow the format bucket-base-name--zone-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide. Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, 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 action with an access point through the Amazon Web Services 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 S3 User Guide. Access points and Object Lambda access points are not supported by directory buckets. S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.
Key name of the object to delete.
