Description

Returns some or all (up to 1,000) of the objects in a bucket with each request. You can use the request parameters as selection criteria to return a subset of the objects in a bucket. A 200 OK response can contain valid or invalid XML. Make sure to design your application to parse the contents of the response and handle it appropriately. For more information about listing objects, see Listing object keys programmatically in the Amazon S3 User Guide. To get a list of your buckets, see ListBuckets. 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-az_id.region.amazonaws.com/key-name. Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.
Permissions
  • General purpose bucket permissions - To use this operation, you must have READ access to the bucket. You must have permission to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.
  • 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.
Sorting order of returned objects
  • General purpose bucket - For general purpose buckets, ListObjectsV2 returns objects in lexicographical order based on their key names.
  • Directory bucket - For directory buckets, ListObjectsV2 does not return objects in lexicographical order.
HTTP Host header syntax
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.
This section describes the latest revision of this action. We recommend that you use this revised API operation for application development. For backward compatibility, Amazon S3 continues to support the prior version of this API operation, ListObjects. The following operations are related to ListObjectsV2:

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-BucketName <String>
Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-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.

Accept pipeline input?True (ByPropertyName)
-ContinuationToken <String>
ContinuationToken indicates to Amazon S3 that the list is being continued on this bucket with a token. ContinuationToken is obfuscated and is not a real key. You can use this ContinuationToken for pagination of the list results.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-ContinuationToken $null' for the first call and '-ContinuationToken $AWSHistory.LastServiceResponse.NextContinuationToken' for subsequent calls.
Required?False

AliasesNextToken
-Delimiter <String>
A delimiter is a character that you use to group keys.
  • Directory buckets - For directory buckets, / is the only supported delimiter.
  • Directory buckets - When you query ListObjectsV2 with a delimiter during in-progress multipart uploads, the CommonPrefixes response parameter contains the prefixes that are associated with the in-progress multipart uploads. For more information about multipart uploads, see Multipart Upload Overview in the Amazon S3 User Guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Encoding <EncodingType>
Encoding type used by Amazon S3 to encode object keys in the response. If using url, non-ASCII characters used in an object's key name will be URL encoded. For example, the object test_file(3).png will appear as test_file%283%29.png.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ExpectedBucketOwner <String>
The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-FetchOwner <Boolean>
The owner field is not present in ListObjectsV2 by default. If you want to return the owner field with each key in the result, then set the FetchOwner field to true.Directory buckets - For directory buckets, the bucket owner is returned as the object owner for all objects.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ForcePathStyleAddressing <Boolean>
S3 requests can be performed using one of two URI styles: Virtual or Path. When using Virtual style, the bucket is included as part of the hostname. When using Path style the bucket is included as part of the URI path. The default value is $true when the EndpointUrl parameter is specified, $false otherwise.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Key <String>
Key value identifying a single object in S3 to return metadata for.
Required?True

-MaxKey <Int32>
Sets the maximum number of keys returned in the response. By default the action returns up to 1,000 key names. The response might contain fewer keys but will never contain more.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
