write-get-object-response

Description

Note

This operation is not supported for directory buckets.

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 regular expression (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)

--content-type (string)

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

--checksum-crc32 (string)

This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This specifies the base64-encoded, 32-bit CRC-32 checksum of the object returned by the Object Lambda function. This may not match the checksum for the object stored in Amazon S3. Amazon S3 will perform validation of the checksum values only when the original GetObject request required checksum validation. For more information about checksums, see Checking object integrity in the Amazon S3 User Guide .

Only one checksum header can be specified at a time. If you supply multiple checksum headers, this request will fail.

--checksum-crc32-c (string)

This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This specifies the base64-encoded, 32-bit CRC-32C checksum of the object returned by the Object Lambda function. This may not match the checksum for the object stored in Amazon S3. Amazon S3 will perform validation of the checksum values only when the original GetObject request required checksum validation. For more information about checksums, see Checking object integrity in the Amazon S3 User Guide .

Only one checksum header can be specified at a time. If you supply multiple checksum headers, this request will fail.

--checksum-sha1 (string)

This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This specifies the base64-encoded, 160-bit SHA-1 digest of the object returned by the Object Lambda function. This may not match the checksum for the object stored in Amazon S3. Amazon S3 will perform validation of the checksum values only when the original GetObject request required checksum validation.

Only one checksum header can be specified at a time. If you supply multiple checksum headers, this request will fail.

--checksum-sha256 (string)

This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This specifies the base64-encoded, 256-bit SHA-256 digest of the object returned by the Object Lambda function. This may not match the checksum for the object stored in Amazon S3. Amazon S3 will perform validation of the checksum values only when the original GetObject request required checksum validation. For more information about checksums, see Checking object integrity in the Amazon S3 User Guide .

Only one checksum header can be specified at a time. If you supply multiple checksum headers, this request will fail.

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

• json
• text
• table
• yaml
• yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

• on
• off
• auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

• base64
• raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.
