PUT Object

Last updated: 2020-07-06 15:26:52

    Feature

    This API is used to upload a local object to the specified bucket. To make this request, you need to have the permission to write to the bucket.

    • This API supports uploading up to 5 GB files. To upload larger files, please use the Multipart Upload API.
    • If the Content-Length is less than the actual length of request body, COS will create an object with the size as specified in Content-Length, but with the excessive data discarded.
    • If you upload an object whose name already exists in an bucket without versioning enabled, the old object will be overwritten by the new one and 200 OK will be returned upon success.

    Versioning

    • If versioning is enabled for the bucket, COS will automatically generate a unique version ID for new object, and return this ID in the response using the x-cos-version-id response header.
    • If versioning is suspended for the bucket, COS will always use null as the version ID of the object in the bucket and will not return the x-cos-version-id response header.

    Request parameters

    This API does not use any request parameter.

    Request headers

    In addition to common request headers, this API also supports the following request headers. For more information, see Common Request Headers.

    Name Description Type Required
    Cache-Control Cache directives as defined in RFC 2616, which are stored as part of object metadata String No
    Content-Disposition File name as defined in RFC 2616, which is stored as part of object metadata String No
    Content-Encoding Encoding format as defined in RFC 2616, which is stored as part of object metadata String No
    Content-Type HTTP request content type (MIME) as defined in RFC 2616 of the object to upload, and stored as part of object metadata
    Example: text/html or image/jpeg    		 String Yes
    Expires The cache expiration time as defined in RFC 2616, which is stored as part of object metadata String No
    Transfer-Encoding To upload data in chunks, you need to specify the Transfer-Encoding: chunked request header. In this case, the request body will follow the transfer encoding format as defined in RFC 2616, while you cannot use the Content-Length request header. String No
    x-cos-meta-* Includes custom metadata and its header suffix, which are stored as part of object metadata. Maximum size: 2 KB.
    Note: custom metadata can contain underscores (_), whereas its header suffix can only contain minus signs (-).    		 String No
    x-cos-storage-class Object storage class. Enumerated values: STANDARD (default), STANDARD_IA and ARCHIVE. For more information, see Storage Class Enum No

    ACL-related headers

    You can configure object access permissions when uploading an object using the following request headers:

    Name Description Type Required
    x-cos-acl Defines the access control list (ACL) attributes of the object. For enumerated values such as default, private, and public-read, see the Preset ACL section in ACL Overview.
    Note: currently, COS supports up to 1,000 bucket ACL rules. If you do not need an object ACL, set this parameter to default (inherit bucket permissions), or leave it empty.    		 Enum No
    x-cos-grant-read Grants permission to read the object; format: id="[OwnerUin]", such as id="100000000001". You can use comma (,) to separate multiple users, such as id="100000000001",id="100000000002" String No
    x-cos-grant-read-acp Grants permission to read the object ACLs; format: id="[OwnerUin]", such as id="100000000001". You can use comma (,) to separate multiple users, such as id="100000000001",id="100000000002" String No
    x-cos-grant-write-acp Grants permission to write to the object ACLs; format: id="[OwnerUin]", such as id="100000000001". You can use comma (,) to separate multiple users, such as id="100000000001",id="100000000002" String No
    x-cos-grant-full-control Grants full permission to operate on the object; format: id="[OwnerUin]", such as id="100000000001". You can use comma (,) to separate multiple users, such as id="100000000001",id="100000000002" String No
