put_object - Boto3 1.34.75 documentation

ACL (string) The canned ACL to apply to the object. For more information, see Canned ACL in the Amazon S3 User Guide. When adding a new object, you can use headers to grant ACL-based permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added

  • ACL (string) –

    The canned ACL to apply to the object. For more information, see Canned ACL in the Amazon S3 User Guide.

    When adding a new object, you can use headers to grant ACL-based permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. By default, all objects are private. Only the owner has full access control. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API in the Amazon S3 User Guide.

    If the bucket that you’re uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don’t specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a 400 error with the error code AccessControlListNotSupported. For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.

  • Body (bytes or seekable file-like object) – Object data.

  • CacheControl (string) – Can be used to specify caching behavior along the request/reply chain. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.

  • ContentDisposition (string) – Specifies presentational information for the object. For more information, see https://www.rfc-editor.org/rfc/rfc6266#section-4.

  • ContentEncoding (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. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#field.content-encoding.

  • ContentLanguage (string) – The language the content is in.

  • ContentLength (integer) – Size of the body in bytes. This parameter is useful when the size of the body cannot be determined automatically. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#name-content-length.

  • ContentMD5 (string) –

    The base64-encoded 128-bit MD5 digest of the message (without the headers) according to RFC 1864. This header can be used as a message integrity check to verify that the data is the same data that was originally sent. Although it is optional, we recommend using the Content-MD5 mechanism as an end-to-end integrity check. For more information about REST request authentication, see REST Authentication.

    Note

    The Content-MD5 header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon S3 User Guide.

    Note

    This functionality is not supported for directory buckets.

  • ContentType (string) – A standard MIME type describing the format of the contents. For more information, see https://www.rfc-editor.org/rfc/rfc9110.html#name-content-type.

  • ChecksumAlgorithm (string) –

    Indicates the algorithm used to create the checksum for the object when you use the SDK. This header will not provide any additional functionality if you don’t use the SDK. When you send this header, there must be a corresponding x-amz-checksum-algorithm or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request.

    For the x-amz-checksum-algorithm header, replace algorithm with the supported algorithm from the following list:

    • CRC32

    • CRC32C

    • SHA1

    • SHA256

    For more information, see Checking object integrity in the Amazon S3 User Guide.

    If the individual checksum value you provide through x-amz-checksum-algorithm doesn’t match the checksum algorithm you set through x-amz-sdk-checksum-algorithm, Amazon S3 ignores any provided ChecksumAlgorithm parameter and uses the checksum algorithm that matches the provided value in ``x-amz-checksum-algorithm ``.

    Note

    For directory buckets, when you use Amazon Web Services SDKs, CRC32 is the default checksum algorithm that’s used for performance.

  • ChecksumCRC32 (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 header specifies the base64-encoded, 32-bit CRC32 checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • ChecksumCRC32C (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 header specifies the base64-encoded, 32-bit CRC32C checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • ChecksumSHA1 (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 header specifies the base64-encoded, 160-bit SHA-1 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • ChecksumSHA256 (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 header specifies the base64-encoded, 256-bit SHA-256 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

  • Expires (datetime) – The date and time at which the object is no longer cacheable. For more information, see https://www.rfc-editor.org/rfc/rfc7234#section-5.3.

  • GrantFullControl (string) –

    Gives the grantee READ, READ_ACP, and WRITE_ACP permissions on the object.

  • GrantRead (string) –

    Allows grantee to read the object data and its metadata.

  • GrantReadACP (string) –

    Allows grantee to read the object ACL.

  • GrantWriteACP (string) –

    Allows grantee to write the ACL for the applicable object.

  • Key (string) –

    [REQUIRED]

    Object key for which the PUT action was initiated.

  • Metadata (dict) –

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

    • (string) –

      • (string) –

  • ServerSideEncryption (string) –

    The server-side encryption algorithm that was used when you store this object in Amazon S3 (for example, AES256, aws:kms, aws:kms:dsse).

    General purpose buckets - You have four mutually exclusive options to protect data using server-side encryption in Amazon S3, depending on how you choose to manage the encryption keys. Specifically, the encryption key options are Amazon S3 managed keys (SSE-S3), Amazon Web Services KMS keys (SSE-KMS or DSSE-KMS), and customer-provided keys (SSE-C). Amazon S3 encrypts data with server-side encryption by using Amazon S3 managed keys (SSE-S3) by default. You can optionally tell Amazon S3 to encrypt data at rest by using server-side encryption with other key options. For more information, see Using Server-Side Encryption in the Amazon S3 User Guide.

    Directory buckets - For directory buckets, only the server-side encryption with Amazon S3 managed keys (SSE-S3) ( AES256) value is supported.

  • StorageClass (string) –

    By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide.

    Note

    • For directory buckets, only the S3 Express One Zone storage class is supported to store newly created objects.

    • Amazon S3 on Outposts only uses the OUTPOSTS Storage Class.

  • WebsiteRedirectLocation (string) –

    If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. For information about object metadata, see Object Key and Metadata in the Amazon S3 User Guide.

    In the following example, the request header sets the redirect to an object (anotherPage.html) in the same bucket:

    x-amz-website-redirect-location: /anotherPage.html

    In the following example, the request header sets the object redirect to another website:

    x-amz-website-redirect-location: http://www.example.com/

    For more information about website hosting in Amazon S3, see Hosting Websites on Amazon S3 and How to Configure Website Page Redirects in the Amazon S3 User Guide.

    Note

    This functionality is not supported for directory buckets.

  • SSECustomerAlgorithm (string) –

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

    Note

    This functionality is not supported for directory buckets.

  • SSECustomerKey (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.

    Note

    This functionality is not supported for directory buckets.

  • SSECustomerKeyMD5 (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.

    Note

    This functionality is not supported for directory buckets.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required

  • SSEKMSKeyId (string) –

    If x-amz-server-side-encryption has a valid value of aws:kms or aws:kms:dsse, this header specifies the ID (Key ID, Key ARN, or Key Alias) of the Key Management Service (KMS) symmetric encryption customer managed key that was used for the object. If you specify x-amz-server-side-encryption:aws:kms or x-amz-server-side-encryption:aws:kms:dsse, but do not provide `` x-amz-server-side-encryption-aws-kms-key-id``, Amazon S3 uses the Amazon Web Services managed key ( aws/s3) to protect the data. If the KMS key does not exist in the same account that’s issuing the command, you must use the full ARN and not just the ID.

    Note

    This functionality is not supported for directory buckets.

  • SSEKMSEncryptionContext (string) –

    Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs. This value is stored as object metadata and automatically gets passed on to Amazon Web Services KMS for future GetObject or CopyObject operations on this object. This value must be explicitly added during CopyObject operations.

    Note

    This functionality is not supported for directory buckets.

  • BucketKeyEnabled (boolean) –

    Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using Key Management Service (KMS) keys (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

    Specifying this header with a PUT action doesn’t affect bucket-level settings for S3 Bucket Key.

    Note

    This functionality is not supported for directory buckets.

  • RequestPayer (string) –

    Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

    Note

    This functionality is not supported for directory buckets.

  • Tagging (string) –

    The tag-set for the object. The tag-set must be encoded as URL Query parameters. (For example, “Key1=Value1”)

    Note

    This functionality is not supported for directory buckets.

  • ObjectLockMode (string) –

    The Object Lock mode that you want to apply to this object.

    Note

    This functionality is not supported for directory buckets.

  • ObjectLockRetainUntilDate (datetime) –

    The date and time when you want this object’s Object Lock to expire. Must be formatted as a timestamp parameter.

    Note

    This functionality is not supported for directory buckets.

  • ObjectLockLegalHoldStatus (string) –

    Specifies whether a legal hold will be applied to this object. For more information about S3 Object Lock, see Object Lock in the Amazon S3 User Guide.

    Note

    This functionality is not supported for directory buckets.

  • ExpectedBucketOwner (string) – The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).
