Object Storage Service:Upload files (Go SDK V1)

Method

Description

Simple upload (Go SDK V1)

• Use a simple upload to upload a File object, BLOB data, or an OSS Buffer to OSS.

• This method is suitable for fast uploads of files up to 5 GB.

Append upload (Go SDK V1)

• Use an append upload to add content to the end of an existing appendable object.

• The file cannot exceed 5 GB.

Resumable upload (Go SDK V1)

• Use a resumable upload for stable uploads of large files.

• Resumable uploads record breakpoints. If a network error or program crash occurs, the upload can resume from the last recorded breakpoint.

• The file cannot exceed 48.8 TB.

Multipart upload (Go SDK V1)

• Use a multipart upload for files larger than 100 MB and smaller than 48.8 TB.

• A multipart upload splits a large file into multiple parts and uploads them separately. After all parts are uploaded, call the CompleteMultipartUpload operation to combine the parts into a single file.

Upload callback (Go SDK V1)

• Use an upload callback to send a notification to an application server after a file is uploaded.

• This lets you perform specific operations after a successful upload, such as recording logs or triggering other processes.

Upload using a signed URL (Go SDK V1)

• To grant temporary permission for others to upload files to your bucket, generate a signed URL. Others can then use this URL to upload files.
