If you need to rename a file within a Bucket, you can use the CopyObject interface to copy the source object to the target object, and then use the DeleteObject interface to delete the source object.
Rename a single object
The following code is used to rename the object src-object in the bucket to dest-object.
package main
import (
"context"
"fmt"
"github.com/volcengine/ve-tos-golang-sdk/v2/tos"
)
func checkErr(err error) {
if err != nil {
if serverErr, ok := err.(*tos.TosServerError); ok {
if serverErr.StatusCode == http.StatusNotFound {
return
}
fmt.Println("Error:", serverErr.Error())
fmt.Println("Request ID:", serverErr.RequestID)
fmt.Println("Response Status Code:", serverErr.StatusCode)
fmt.Println("Response Header:", serverErr.Header)
fmt.Println("Response Err Code:", serverErr.Code)
fmt.Println("Response Err Msg:", serverErr.Message)
} else if clientErr, ok := err.(*tos.TosClientError); ok {
fmt.Println("Error:", clientErr.Error())
fmt.Println("Client Cause Err:", clientErr.Cause.Error())
} else {
fmt.Println("Error:", err)
}
panic(err)
}
}
func main() {
var (
accessKey = os.Getenv("TOS_ACCESS_KEY")
secretKey = os.Getenv("TOS_SECRET_KEY")
endpoint = "https://tos-cn-beijing.volces.com"
region = "cn-beijing"
bucketName = "*** Provide your bucket name ***"
ctx = context.Background()
)
client, err := tos.NewClientV2(endpoint, tos.WithRegion(region), tos.WithCredentials(tos.NewStaticCredentials(accessKey, secretKey)))
checkErr(err)
srcObjectKey := "src-object"
dstObjectKey := "dest-object"
output, err := client.CopyObject(ctx, &tos.CopyObjectInput{
Bucket: bucketName,
Key: dstObjectKey,
SrcBucket: bucketName,
SrcKey: srcObjectKey,
})
checkErr(err)
fmt.Println("CopyObject Request ID:", output.RequestID)
deleteOutput, err := client.DeleteObjectV2(ctx, &tos.DeleteObjectV2Input{
Bucket: bucketName,
Key: srcObjectKey,
})
checkErr(err)
fmt.Println("DeleteObjectV2 Request ID:", deleteOutput.RequestID)
}
Rename Directory
The following code is used to rename the directory exampledir1/ to exampledir2/ within the specified storage bucket.
package main
import (
"context"
"fmt"
"strings"
"github.com/volcengine/ve-tos-golang-sdk/v2/tos"
)
func checkErr(err error) {
if err != nil {
if serverErr, ok := err.(*tos.TosServerError); ok {
if serverErr.StatusCode == http.StatusNotFound {
return
}
fmt.Println("Error:", serverErr.Error())
fmt.Println("Request ID:", serverErr.RequestID)
fmt.Println("Response Status Code:", serverErr.StatusCode)
fmt.Println("Response Header:", serverErr.Header)
fmt.Println("Response Err Code:", serverErr.Code)
fmt.Println("Response Err Msg:", serverErr.Message)
} else if clientErr, ok := err.(*tos.TosClientError); ok {
fmt.Println("Error:", clientErr.Error())
fmt.Println("Client Cause Err:", clientErr.Cause.Error())
} else {
fmt.Println("Error:", err)
}
panic(err)
}
}
func main() {
var (
accessKey = os.Getenv("TOS_ACCESS_KEY")
secretKey = os.Getenv("TOS_SECRET_KEY")
endpoint = "https://tos-cn-beijing.volces.com"
region = "cn-beijing"
bucketName = "*** Provide your bucket name ***"
ctx = context.Background()
)
client, err := tos.NewClientV2(endpoint, tos.WithRegion(region), tos.WithCredentials(tos.NewStaticCredentials(accessKey, secretKey)))
checkErr(err)
truncated := true
continuationToken := ""
oldPrefix := "exampledir1/"
newPrefix := "exampledir2/"
for truncated {
output, err := client.ListObjectsType2(ctx, &tos.ListObjectsType2Input{
Bucket: bucketName,
MaxKeys: 1000,
ContinuationToken: continuationToken,
Prefix: oldPrefix,
})
checkErr(err)
for _, obj := range output.Contents {
newKey := strings.Replace(obj.Key, oldPrefix, newPrefix, 1)
output, err := client.CopyObject(ctx, &tos.CopyObjectInput{
Bucket: bucketName,
Key: newKey,
SrcBucket: bucketName,
SrcKey: obj.Key,
})
checkErr(err)
fmt.Println("CopyObject Request ID:", output.RequestID)
deleteOutput, err := client.DeleteObjectV2(ctx, &tos.DeleteObjectV2Input{
Bucket: bucketName,
Key: obj.Key,
})
checkErr(err)
fmt.Println("DeleteObjectV2 Request ID:", deleteOutput.RequestID)
}
truncated = output.IsTruncated
continuationToken = output.NextContinuationToken
}
}
