This article introduces code examples for common object deletion scenarios.
Delete Directory
The following code is used to delete objects under the directory exampledir.
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)
truncated := true
continuationToken := ""
prefix := "exampledir/"
for truncated {
output, err := client.ListObjectsType2(ctx, &tos.ListObjectsType2Input{
Bucket: bucketName,
MaxKeys: 1000,
ContinuationToken: continuationToken,
Prefix: prefix,
})
checkErr(err)
for _, obj := range output.Contents {
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
}
}
Empty Bucket
The following code is used to clear the entire bucket, including deleting all objects and all unmerged objects.
package main
import (
"context"
"fmt"
"net/http"
"os"
"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()
)

checkErr(err)
truncated := true
continuationToken := ""
for truncated {
output, err := client.ListObjectsType2(ctx, &tos.ListObjectsType2Input{
Bucket: bucketName,
MaxKeys: 1000,
ContinuationToken: continuationToken,
})
checkErr(err)
for _, obj := range output.Contents {
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
}
truncated = true
marker := ""
uploadIDMarker := ""
for truncated {
output, err := client.ListMultipartUploadsV2(ctx, &tos.ListMultipartUploadsV2Input{
Bucket: bucketName,
MaxUploads: 1000,
KeyMarker: marker,
UploadIDMarker: uploadIDMarker,

}
}
Emptying a bucket with versioning enabled
The following code provides an example for clearing an entire multi-version enabled bucket, including deleting all versions of all objects, deleting all versions of delete markers, and deleting all unmerged objects.
package main
import (
"context"
"fmt"
"net/http"
"os"
"github.com/volcengine/ve-tos-golang-sdk/v2/tos"

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)
}
}

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
marker := ""
versionIdMarker := ""
for truncated {
listOutput, err := client.ListObjectVersionsV2(ctx, &tos.ListObjectVersionsV2Input{
Bucket: bucketName,
ListObjectVersionsInput: tos.ListObjectVersionsInput{
MaxKeys: 1000,
KeyMarker: marker,
VersionIDMarker: versionIdMarker,
},
})
checkErr(err)
for _, obj := range listOutput.Versions {
output, err := client.DeleteObjectV2(ctx, &tos.DeleteObjectV2Input{
Bucket: bucketName,
Key: obj.Key,
VersionID: obj.VersionID,
})
checkErr(err)
fmt.Printf("Delete %s, Request ID: %s\n", obj.Key, output.RequestID)
}
for _, deleteMarker := range listOutput.DeleteMarkers {
output, err := client.DeleteObjectV2(ctx, &tos.DeleteObjectV2Input{

Bucket: bucketName,
MaxUploads: 1000,

})
checkErr(err)
for _, upload := range output.Uploads {
abortUpload, err := client.AbortMultipartUpload(ctx, &tos.AbortMultipartUploadInput{
