Interface Description

This interface is used to upload a file to the specified bucket. The requester must have the write permission. Before PutObject, you need to ensure that the corresponding bucket already exists. The length range of object files supported by BOS is 0-5 GB. If you need to upload files larger than 5 GB, see MultiPartUpload Guide.

  Name	Type	Description	Required?
  Cache-Control	String	Cache setting for downloading the object. The common optional values are private, no-cache, max-age and must-revalidate	No
  Content-Disposition	String	Set the browser to download files. The optional values are inline and attachment. Filename="download.txt".	No
  Content-MD5	String	The MD5 digest of the HTTP request content defined in RFC2616 can be contained to verify whether the file saved in BOS is consistent with the user expected file.	No

  x-bce-meta-*	String	User-defined meta	No
  x-bce-content-sha256	String	It verifies whether the file saved in BOS is consistent with the user expected file through this field, and the verification accuracy of Sha256 is higher. The Sha256 value of the data transmitted must match it. Otherwise, PutObject fails.	No
  x-bce-content-crc32	String	It uploads the CRC (cyclic redundancy check) value of the object.	No
  x-bce-storage-class	String	It specifies the storage type of the object. STANDARD_IA represents the infrequent access, COLD represents the cold storage, and ARCHIVE represents the archive storage. If it is not specified, it is the STANDARD by default. If it is a Multi-AZ bucket, MAZ_STANDARD_IArepresents the Multi-AZ infrequent access. If it is not specified, it is a MAZ_STANDARDstorage by default and cannot be other values.	No
  x-bce-acl	String	Header supported by CannedACL, in which the user sets the permission of the object, whose value is private or public-read.	No
  x-bce-grant-read	String	Header supported by CannedACL, in which the user sets the read permission of the object. It supports multiple IDs, separated by commas	No
  x-bce-grant-full-control	String	Header supported by CannedACL, in which the user sets the FULL_CONTROL permission of the object. It supports multiple IDs, separated by commas	No
  x-bce-server-side-encryption	String	Server encryption algorithm, only AES256 is supported currently.	No

Response

• Response header field

  Name	Type	Description
  ETag	String	HTTP protocol entity tag of the object.

Considerations

1. Content-Length is a required parameter. If Content-Length specified by the requester is shorter than the actual request body (actual data of object), BOS only saves the data with the length specified by Content-Length, and the excessive data is discarded directly. In contrast, if Content-Length is long, BOS waits for the requester to upload the data until it is timeout.
2. At present, BOS does not support the version. If the requester repeatedly puts an object, the data uploaded previously is overwritten.
