Network.AWS.S3.ListObjectsV2

Returns some or all (up to 1000) of the objects in a bucket. You can use the request parameters as selection criteria to return a subset of the objects in a bucket. Note: ListObjectsV2 is the revised List Objects API and we recommend you use this revised API for new application development.

This operation returns paginated results.

Creating a Request

listObjectsV2

Arguments

:: BucketName

lovBucket

-> ListObjectsV2

Creates a value of ListObjectsV2 with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• lovStartAfter - StartAfter is where you want Amazon S3 to start listing from. Amazon S3 starts listing after this specified key. StartAfter can be any key in the bucket
• lovContinuationToken - ContinuationToken indicates Amazon S3 that the list is being continued on this bucket with a token. ContinuationToken is obfuscated and is not a real key
• lovFetchOwner - The owner field is not present in listV2 by default, if you want to return owner field with each key in the result then set the fetch owner field to true
• lovPrefix - Limits the response to keys that begin with the specified prefix.
• lovEncodingType - Encoding type used by Amazon S3 to encode object keys in the response.
• lovRequestPayer - Confirms that the requester knows that she or he will be charged for the list objects request in V2 style. Bucket owners need not specify this parameter in their requests.
• lovMaxKeys - Sets the maximum number of keys returned in the response. The response might contain fewer keys but will never contain more.
• lovDelimiter - A delimiter is a character you use to group keys.
• lovBucket - Name of the bucket to list.

Destructuring the Response

listObjectsV2Response

Arguments

:: Int

• lovrsMaxKeys - Sets the maximum number of keys returned in the response. The response might contain fewer keys but will never contain more.
• lovrsIsTruncated - A flag that indicates whether or not Amazon S3 returned all of the results that satisfied the search criteria.
