write-get-object-response

Description

Passes transformed objects to a GetObject operation when using Object Lambda access points. For information about Object Lambda access points, see Transforming objects with Object Lambda access points in the Amazon S3 User Guide .

This operation supports metadata that can be returned by GetObject , in addition to RequestRoute , RequestToken , StatusCode , ErrorCode , and ErrorMessage . The GetObject response metadata is supported so that the WriteGetObjectResponse caller, typically an Lambda function, can provide the same metadata when it internally invokes GetObject . When WriteGetObjectResponse is called by a customer-owned Lambda function, the metadata returned to the end user GetObject call might differ from what Amazon S3 would normally return.

You can include any number of metadata headers. When including a metadata header, it should be prefaced with x-amz-meta . For example, x-amz-meta-my-custom-header: MyCustomValue . The primary use case for this is to forward GetObject metadata.

Amazon Web Services provides some prebuilt Lambda functions that you can use with S3 Object Lambda to detect and redact personally identifiable information (PII) and decompress S3 objects. These Lambda functions are available in the Amazon Web Services Serverless Application Repository, and can be selected through the Amazon Web Services Management Console when you create your Object Lambda access point.

Example 1: PII Access Control - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically detects personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.

Example 2: PII Redaction - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically redacts personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.

Example 3: Decompression - The Lambda function S3ObjectLambdaDecompression, is equipped to decompress objects stored in S3 in one of six compressed file formats including bzip2, gzip, snappy, zlib, zstandard and ZIP.

For information on how to view and use these functions, see Using Amazon Web Services built Lambda functions in the Amazon S3 User Guide .

The object data.

--status-code (integer)

The integer status code for an HTTP response of a corresponding GetObject request.

Status Codes

  • 206 - Partial Content

  • 304 - Not Modified

  • 400 - Bad Request

  • 401 - Unauthorized

  • 403 - Forbidden

  • 404 - Not Found

  • 412 - Precondition Failed

  • 416 - Range Not Satisfiable

  • 500 - Internal Server Error

  • 503 - Service Unavailable

--error-code (string)

A string that uniquely identifies an error condition. Returned in the <Code> tag of the error XML response for a corresponding GetObject call. Cannot be used with a successful StatusCode header or when the transformed object is provided in the body. All error codes from S3 are sentence-cased. Regex value is “^[A-Z][a-zA-Z]+$”.

--error-message (string)

Contains a generic description of the error condition. Returned in the <Message> tag of the error XML response for a corresponding GetObject call. Cannot be used with a successful StatusCode header or when the transformed object is provided in body.

--accept-ranges (string)

Indicates that a range of bytes was specified.

--cache-control (string)

Specifies caching behavior along the request/reply chain.

--content-disposition (string)

Specifies presentational information for the object.

--content-encoding (string)

Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.

--content-language (string)

The language the content is in.

--content-length (long)

The size of the content body in bytes.

--content-range (string)

The portion of the object returned in the response.

--content-type (string)

A standard MIME type describing the format of the object data.

--delete-marker | --no-delete-marker (boolean)

Specifies whether an object stored in Amazon S3 is (true ) or is not (false ) a delete marker.

--e-tag (string)

An opaque identifier assigned by a web server to a specific version of a resource found at a URL.

--expires (timestamp)

The date and time at which the object is no longer cacheable.

--expiration (string)

If object stored in Amazon S3 expiration is configured (see PUT Bucket lifecycle) it includes expiry-date and rule-id key-value pairs providing object expiration information. The value of the rule-id is URL encoded.

--last-modified (timestamp)

The date and time that the object was last modified.

--missing-meta (integer)

Set to the number of metadata entries not returned in x-amz-meta headers. This can happen if you create metadata using an API like SOAP that supports more flexible metadata than the REST API. For example, using SOAP, you can create metadata whose values are not legal HTTP headers.

--metadata (map)

A map of metadata to store with the object in S3.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
