Instance Method Details

#copy_from(options = {}) ⇒ Types::UploadPartCopyOutput

Uploads a part by copying data from an existing object as data source. You specify the data source by adding the request header x-amz-copy-source in your request and a byte range by adding the request header x-amz-copy-source-range in your request.

The minimum allowable part size for a multipart upload is 5 MB. For more information about multipart upload limits, go to Quick Facts in the Amazon Simple Storage Service Developer Guide.

Instead of using an existing object as part data, you might use the UploadPart operation and provide data in your request.

You must initiate a multipart upload before you can upload any part. In response to your initiate request. Amazon S3 returns a unique identifier, the upload ID, that you must include in your upload part request.

For more information about using the UploadPartCopy operation, see the following:

  • For conceptual information about multipart uploads, see Uploading Objects Using Multipart Upload in the Amazon Simple Storage Service Developer Guide.

  • For information about permissions required to use the multipart upload API, see Multipart Upload API and Permissions in the Amazon Simple Storage Service Developer Guide.

  • For information about copying objects using a single atomic operation vs. the multipart upload, see Operations on Objects in the Amazon Simple Storage Service Developer Guide.

  • For information about using server-side encryption with customer-provided encryption keys with the UploadPartCopy operation, see CopyObject and UploadPart.

Note the following additional considerations about the request headers x-amz-copy-source-if-match, x-amz-copy-source-if-none-match, x-amz-copy-source-if-unmodified-since, and x-amz-copy-source-if-modified-since:

  • Consideration 1 - If both of the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request as follows:

    x-amz-copy-source-if-match condition evaluates to true, and;

    x-amz-copy-source-if-unmodified-since condition evaluates to false;

    Amazon S3 returns 200 OK and copies the data.

  • Consideration 2 - If both of the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request as follows:

    x-amz-copy-source-if-none-match condition evaluates to false, and;

    x-amz-copy-source-if-modified-since condition evaluates to true;

    Amazon S3 returns 412 Precondition Failed response code.

Versioning

If your bucket has versioning enabled, you could have multiple versions of the same object. By default, x-amz-copy-source identifies the current version of the object to copy. If the current version is a delete marker and you don't specify a versionId in the x-amz-copy-source, Amazon S3 returns a 404 error, because the object does not exist. If you specify versionId in the x-amz-copy-source and the versionId is a delete marker, Amazon S3 returns an HTTP 400 error, because you are not allowed to specify a delete marker as a version for the x-amz-copy-source.

You can optionally specify a specific version of the source object to copy by adding the versionId subresource as shown in the following example:

x-amz-copy-source: /bucket/object?versionId=version id

Special Errors

    • Code: NoSuchUpload

    • Cause: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed.

    • HTTP Status Code: 404 Not Found

    • Code: InvalidRequest

    • Cause: The specified copy source is not supported as a byte-range copy source.

    • HTTP Status Code: 400 Bad Request

Options Hash (options):

  • :copy_source (required, String) —

    Specifies the source object for the copy operation. You specify the value in one of two formats, depending on whether you want to access the source object through an access point:

    • For objects not accessed through an access point, specify the name of the source bucket and key of the source object, separated by a slash (/). For example, to copy the object reports/january.pdf from the bucket awsexamplebucket, use awsexamplebucket/reports/january.pdf. The value must be URL encoded.

    • For objects accessed through access points, specify the Amazon Resource Name (ARN) of the object as accessed through the access point, in the format arn:aws:s3:<Region>:<account-id>:accesspoint/<access-point-name>/object/<key>. For example, to copy the object reports/january.pdf through access point my-access-point owned by account 123456789012 in Region us-west-2, use the URL encoding of arn:aws:s3:us-west-2:123456789012:accesspoint/my-access-point/object/reports/january.pdf. The value must be URL encoded.

      Amazon S3 supports copy operations using access points only when the source and destination buckets are in the same AWS Region.

      Alternatively, for objects accessed through Amazon S3 on Outposts, specify the ARN of the object as accessed in the format arn:aws:s3-outposts:<Region>:<account-id>:outpost/<outpost-id>/object/<key>. For example, to copy the object reports/january.pdf through outpost my-outpost owned by account 123456789012 in Region us-west-2, use the URL encoding of arn:aws:s3-outposts:us-west-2:123456789012:outpost/my-outpost/object/reports/january.pdf. The value must be URL encoded.

    To copy a specific version of an object, append ?versionId=<version-id> to the value (for example, awsexamplebucket/reports/january.pdf?versionId=QUpfdndhfd8438MNFDN93jdnJFkdmqnh893). If you don\'t specify a version ID, Amazon S3 copies the latest version of the source object.

  • :copy_source_if_match (String) —

    Copies the object if its entity tag (ETag) matches the specified tag.

  • :copy_source_if_modified_since (Time) —

    Copies the object if it has been modified since the specified time.

  • :copy_source_if_none_match (String) —

    Copies the object if its entity tag (ETag) is different than the specified ETag.

  • :copy_source_if_unmodified_since (Time) —

    Copies the object if it hasn\'t been modified since the specified time.

  • :copy_source_range (String) —

    The range of bytes to copy from the source object. The range value must use the form bytes=first-last, where the first and last are the zero-based byte offsets to copy. For example, bytes=0-9 indicates that you want to copy the first 10 bytes of the source. You can copy a range only if the source object is greater than 5 MB.

  • :sse_customer_algorithm (String) —

    Specifies the algorithm to use to when encrypting the object (for example, AES256).

  • :sse_customer_key (String) —

    Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header. This must be the same encryption key specified in the initiate multipart upload request.

  • :sse_customer_key_md5 (String) —

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

  • :copy_source_sse_customer_algorithm (String) —

    Specifies the algorithm to use when decrypting the source object (for example, AES256).

  • :copy_source_sse_customer_key (String) —

    Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be one that was used when the source object was created.

  • :copy_source_sse_customer_key_md5 (String) —

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

  • :request_payer (String) —

    Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from requester pays buckets, see Downloading Objects in Requestor Pays Buckets in the Amazon S3 Developer Guide.

  • :expected_bucket_owner (String) —

    The account id of the expected destination bucket owner. If the destination bucket is owned by a different account, the request will fail with an HTTP 403 (Access Denied) error.

  • :expected_source_bucket_owner (String) —

    The account id of the expected source bucket owner. If the source bucket is owned by a different account, the request will fail with an HTTP 403 (Access Denied) error.

  • :use_accelerate_endpoint (Boolean) —

    When true, the "https://BUCKETNAME.s3-accelerate.amazonaws.com" endpoint will be used.

#upload(options = {}) ⇒ Types::UploadPartOutput

Uploads a part in a multipart upload.

In this operation, you provide part data in your request. However, you have an option to specify your existing Amazon S3 object as a data source for the part you are uploading. To upload a part from an existing object, you use the UploadPartCopy operation.

You must initiate a multipart upload (see CreateMultipartUpload) before you can upload any part. In response to your initiate request, Amazon S3 returns an upload ID, a unique identifier, that you must include in your upload part request.

Part numbers can be any number from 1 to 10,000, inclusive. A part number uniquely identifies a part and also defines its position within the object being created. If you upload a new part using the same part number that was used with a previous part, the previously uploaded part is overwritten. Each part must be at least 5 MB in size, except the last part. There is no size limit on the last part of your multipart upload.

To ensure that data is not corrupted when traversing the network, specify the Content-MD5 header in the upload part request. Amazon S3 checks the part data against the provided MD5 value. If they do not match, Amazon S3 returns an error.

If the upload request is signed with Signature Version 4, then AWS S3 uses the x-amz-content-sha256 header as a checksum instead of Content-MD5. For more information see Authenticating Requests: Using the Authorization Header (AWS Signature Version 4).

Note: After you initiate multipart upload and upload one or more parts, you must either complete or abort multipart upload in order to stop getting charged for storage of the uploaded parts. Only after you either complete or abort multipart upload, Amazon S3 frees up the parts storage and stops charging you for the parts storage.

For more information on multipart uploads, go to Multipart Upload Overview in the Amazon Simple Storage Service Developer Guide .

For information on the permissions required to use the multipart upload API, go to Multipart Upload API and Permissions in the Amazon Simple Storage Service Developer Guide.

You can optionally request server-side encryption where Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it for you when you access it. You have the option of providing your own encryption key, or you can use the AWS managed encryption keys. If you choose to provide your own encryption key, the request headers you provide in the request must match the headers you used in the request to initiate the upload by using CreateMultipartUpload. For more information, go to Using Server-Side Encryption in the Amazon Simple Storage Service Developer Guide.

Server-side encryption is supported by the S3 Multipart Upload actions. Unless you are using a customer-provided encryption key, you don't need to specify the encryption parameters in each UploadPart request. Instead, you only need to specify the server-side encryption parameters in the initial Initiate Multipart request. For more information, see CreateMultipartUpload.

If you requested server-side encryption using a customer-provided encryption key in your initiate multipart upload request, you must provide identical encryption information in each part upload using the following headers.

  • x-amz-server-side-encryption-customer-algorithm

  • x-amz-server-side-encryption-customer-key

  • x-amz-server-side-encryption-customer-key-MD5

Special Errors

    • Code: NoSuchUpload

    • Cause: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed.

    • HTTP Status Code: 404 Not Found

    • SOAP Fault Code Prefix: Client
