When an object is no longer in use, you may delete it to reduce cost overhead. Currently, the TOS Go SDK supports deleting individual objects and specified multiple objects within a bucket. For buckets with versioning enabled, you can specify and delete any version of an object's data.
Precautions
- Before deleting an object, you must have the tos:DeleteObject permission. For detailed instructions, see the Permissions Configuration Guide.
- For buckets with versioning enabled, you must have the tos:DeleteObjectVersion permission before deleting a specified version of an object. For detailed instructions, please refer to the Permissions Configuration Guide.
Sample Code
Delete Specified Object
package main
import (
"context"
"fmt"
"github.com/volcengine/ve-tos-golang-sdk/v2/tos"

func checkErr(err error) {
if err != nil {

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)

fmt.Println("Error:", clientErr.Error())
fmt.Println("Client Cause Err:", clientErr.Cause.Error())

Delete the specified version of an object

Bulk Object Deletion
warning
- In a bucket with versioning enabled, when the DeleteMultiObjects API is called to delete objects in bulk, if the versionId is not specified in the Delete request, a delete marker will be inserted. If versionId is specified, the specified version of the object will be permanently deleted.
- The supported response mode for batch object deletion can be configured using quiet:
- When quiet is set to false, the response will include the deletion result regardless of whether the object was successfully deleted.
- When quiet is set to true, the response only includes the results of objects whose deletion failed; objects not included in the response are considered successfully deleted.

Batch Deletion of Objects of a Specified Version
The following code is used to delete multiple objects, identified by specified object names and version numbers, from a designated storage bucket.
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 {
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 ***"
objectKey1 = "*** Provide Object Key ***"
versionID1 = "*** Provide objectKey1 Version ID ***"
objectKey2 = "*** Provide Object Key ***"
versionID2 = "*** Provide objectKey2 Version ID ***"
ctx = context.Background()
)
client, err := tos.NewClientV2(endpoint, tos.WithRegion(region), tos.WithCredentials(tos.NewStaticCredentials(accessKey, secretKey)))
checkErr(err)
objects := make([]tos.ObjectTobeDeleted, 2)
objects[0] = tos.ObjectTobeDeleted{Key: objectKey1, VersionID: versionID1}
objects[1] = tos.ObjectTobeDeleted{Key: objectKey2, VersionID: versionID2}
output, err := client.DeleteMultiObjects(ctx, &tos.DeleteMultiObjectsInput{
Bucket: bucketName,
Objects: objects,
})
checkErr(err)
fmt.Println("DeleteMultiObjects Request ID:", output.RequestID)
}
Delete all objects in the bucket
The following code demonstrates how to delete all objects within a specified Bucket.

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)
keyMarker := ""
isTruncated := true
for isTruncated {
listOutput, err := client.ListObjectVersionsV2(ctx, &tos.ListObjectVersionsV2Input{
Bucket: bucketName,
ListObjectVersionsInput: tos.ListObjectVersionsInput{
KeyMarker: keyMarker,
},
})
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,
Key: deleteMarker.Key,
VersionID: deleteMarker.VersionID,
})
checkErr(err)
fmt.Printf("Delete deleteMarker %s, Request ID: %s\n", deleteMarker.Key, output.RequestID)
