How to use OSS SDK for Go to upload objects - Object Storage Service

OSS SDK for Go V2 provides multiple upload operations. Choose the one that best fits your scenario.

Type	Operation	Description
Simple upload	Client.PutObject	Uploads an object up to 5 GiB in size. Supports CRC-64 (enabled by default). Displays upload progress. Accepts an io.Reader request body. If the request body also implements io.Seeker, the upload is automatically retried on failure.
Simple upload	Client.PutObjectFromFile	Provides the same capability as Client.PutObject. Reads the request body from a local file path.
Append upload	Client.AppendObject	Appends data to an object up to 5 GiB in size. Supports CRC-64 (enabled by default). Displays upload progress. Accepts an io.Reader request body. If the request body also implements io.Seeker, the upload is automatically retried on failure. The operation is idempotent, but retries may still fail.
Append upload	AppendOnlyFile operations AppendOnlyFile.Write AppendOnlyFile.WriteFrom	Provides the same capability as Client.AppendObject. Improves fault tolerance for retry failures.
Multipart upload	Multipart upload operations Client.InitiateMultipartUpload Client.UploadPart Client.CompleteMultipartUpload	Uploads an object up to 48.8 TiB in size, with each part up to 5 GiB. UploadPart supports CRC-64 (enabled by default). UploadPart displays upload progress. Accepts an io.Reader request body. If the request body also implements io.Seeker, the upload is automatically retried on failure.
Form upload	/	Generates a signature and upload policy, and uploads an object to OSS by using HTTP POST.
A signed URL	Client.Presign	Generates a time-limited signed URL that authorizes HTTP PUT uploads.
Uploader	Uploader.UploadFrom	Wraps simple upload and multipart upload to upload an object up to 48.8 TiB in size. Supports CRC-64 (enabled by default). Displays upload progress. Accepts an io.Reader request body. If the request body also implements io.Seeker and io.ReaderAt, data is streamed without memory caching. Otherwise, data is cached in memory before upload.
Uploader	Uploader.UploadFile	Provides the same capability as Uploader.UploadFrom. Reads the request body from a local file path. Supports resumable upload.
