Object Storage Service:Rename objects

Usage notes

• In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS from other Alibaba Cloud services in the same region as OSS, use an internal endpoint. For more information about OSS regions and endpoints, see Regions, endpoints and open ports.

• In this topic, access credentials are obtained from environment variables. For more information about how to configure access credentials, see Configure access credentials.

• In this topic, an OSSClient instance is created by using an OSS endpoint. If you want to create an OSSClient instance by using custom domain names or Security Token Service (STS), see Initialization.

Sample code

The following sample code provides examples on how to rename an object named srcobject.txt in the examplebucket bucket to destobject.txt:

package main

import (
	"fmt"
	"log"

	"github.com/aliyun/aliyun-oss-go-sdk/oss"
)

func main() {
	// Obtain access credentials from environment variables. Before you run the sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are configured. 
	provider, err := oss.NewEnvironmentVariableCredentialsProvider()
	if err != nil {
		log.Fatalf("Failed to create credentials provider: %v", err)
	}

	// Create an OSSClient instance. 
	// Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com. Specify your actual endpoint. 
	// Specify the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the region to cn-hangzhou. Specify the actual region.
	clientOptions := []oss.ClientOption{oss.SetCredentialsProvider(&provider)}
	clientOptions = append(clientOptions, oss.Region("yourRegion"))
	// Specify the version of the signature algorithm.
	clientOptions = append(clientOptions, oss.AuthVersion(oss.AuthV4))
	client, err := oss.New("yourEndpoint", "", "", clientOptions...)
	if err != nil {
		log.Fatalf("Failed to create OSS client: %v", err)
	}

	// Specify the name of the bucket. 
	bucketName := "examplebucket"
	bucket, err := client.Bucket(bucketName)
	if err != nil {
		log.Fatalf("Failed to get bucket '%s': %v", bucketName, err)
	}

	// Specify the full path of the source object. Do not include the bucket name in the full path. 
	srcObject := "srcobject.txt"
	// Specify the full path of the destination object. Do not include the bucket name in the full path. 
	destObject := "destobject.txt"

	// Copy the srcobject.txt object in examplebucket to the destobject.txt object in the same bucket. 
	_,err = bucket.CopyObject(srcObject,destObject)
	if err != nil {
		log.Fatalf("Failed to copy object '%s' to '%s': %v", srcObject, destObject, err)
	}

	// Delete the srcobject.txt object. 
	err = bucket.DeleteObject(srcObject)
	if err != nil {
		log.Fatalf("Failed to delete source object '%s': %v", srcObject, err)
	}

	fmt.Printf("%s has been renamed to %s\n", srcObject, destObject)
}
