In OBS, objects are basic data units that users can perform operations on. OBS Java SDK provides abundant APIs for object upload in the following methods:

The SDK supports the upload of objects whose size ranges from 0 KB to 5 GB. For streaming upload, appendable upload, and file-based upload, data to be uploaded cannot be larger than 5 GB. If the file is larger than 5 GB, multipart upload (where each part is smaller than 5 GB) is suitable. Browser-based upload allows files to be uploaded through a browser.

If you grant anonymous users the read permission for an object during the upload, anonymous users can access the object through a URL after the upload is complete. The object URL is in the format of https://bucket name.domain name/directory level/object name. If the object resides in the root directory of the bucket, its URL does not contain directory levels.
