Uploading an Object - POST

Functions

This API allows you to upload an object to a bucket. This requires the write permission for the bucket.

Note

The name of each object in a bucket must be unique.

If a bucket has versioning disabled, and you upload an object that has the same name as an existing object, the new object overwrites the existing one. You can also use Content-MD5 in the form to verify in-transit integrity. OBS calculates an MD5 after the object is uploaded and checks if this MD5 matches the MD5 carried in the form. If they do not match, an error is reported. You can also use x-obs-acl to control access to objects.

You can also upload an object using the POST method.

A single upload allows at most 5 GB of objects. To upload more than 5 GB of objects, see Operations on Multipart Upload.

This API supports server-side encryption.

Differences Between PUT and POST Methods

PUT requests include parameters in the header; POST requests in the form.

In the URL, PUT requests require object names be specified; POST requests only require bucket domain names. Request lines of PUT and POST are as follows:

PUT /ObjectName HTTP/1.1

POST / HTTP/1.1

For details about PUT upload, see Uploading an Object - PUT.

Versioning

If versioning is enabled for a bucket, each object uploaded has a unique version ID. If versioning is suspended, the version ID is null. Version IDs are returned in the x-obs-version-id header of the response. For details about versioning, see Configuring Versioning for a Bucket.

WORM

If a bucket has WORM enabled, you can configure WORM for its objects. To do so, use x-obs-object-lock-mode and x-obs-object-lock-retain-until-date in the request when uploading an object. If these two elements are not specified, objects uploaded use the default bucket WORM policy (if any). You can also configure or update WORM after an object was uploaded.

Note

If WORM is enabled, versioning is automatically enabled. WORM is based on the object version. Versions of an object not protected by WORM can be deleted. For example, assume version test.txt 001 of an object is protected by WORM. You upload a new version test.txt 002 for the same object with no WORM configured. In such case, test.txt 002 is not protected and can be deleted. If you download an object without specifying a version ID, the latest version — test.txt 002 — is downloaded.
