Container for the parameters to the WriteGetObjectResponse operation.

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.

You must URL encode any signed header values that contain spaces. For example, if your header value is my file.txt, containing two spaces after my, you must URL encode this value to my%20%20file.txt.

Properties

NameTypeDescription
Public Property AcceptRanges System.String

Gets and sets the property AcceptRanges.

Indicates that a range of bytes was specified.

Public Property Body System.IO.Stream

Public Property ChecksumCRC32 System.String

Gets and sets the property ChecksumCRC32.

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 CRC32 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.

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 CRC32C 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.

Public Property ChecksumCRC64NVME System.String

Gets and sets the property ChecksumCRC64NVME.

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 SHA1 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.

Public Property ChecksumSHA256 System.String

Gets and sets the property ChecksumSHA256.

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 SHA256 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.

This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

Public Property MissingMeta System.Nullable<System.Int32>

Gets and sets the property MissingMeta.
