CopyObject enables the copying of objects between buckets within the same region, as well as within a single bucket. During copying, you may specify new metadata or retain the metadata of the source object.
Precautions
- File copying does not support cross-region bucket-to-bucket copying.
- When copying an object, the account must have read permission for the source object and write permission for the destination bucket.
- When copying an object, you can retain all metadata (default) or specify new metadata. However, the ACL was not retained; instead, it was set to private.
Sample Code
package main
import (
"context"
"fmt"
"github.com/volcengine/ve-tos-golang-sdk/v2/tos"
"github.com/volcengine/ve-tos-golang-sdk/v2/tos/enum"
)
func checkErr(err error) {

fmt.Println("Response Status Code:", serverErr.StatusCode)
fmt.Println("Response Header:", serverErr.Header)
fmt.Println("Response Err Code:", serverErr.Code)
