Object Upload Overview
If you have any questions during the development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.
In OBS, objects are basic data units that users can perform operations on. OBS .NET SDK provides abundant APIs for object upload in the following methods:
- Performing a Streaming Upload
- Performing a File-Based Upload
- Performing an Asynchronous Upload
- Performing a Multipart Upload
- Performing an Appendable Upload
- Performing a Resumable Upload
The SDK supports the upload of objects whose size ranges from 0 KB to 5 GB. If a file is smaller than 5 GB, streaming upload, appendable upload, and file-based upload are applicable. If the file is larger than 5 GB, multipart upload (whose part size is smaller than 5 GB) is suitable.
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 levels/object name. If the object resides in the root directory of the bucket, its URL does not contain directory levels.
