For the sample code, please refer to File Deletion Demo

Delete single file

The following code can be referenced to delete an object:

                Java
                
                public void deleteObject(BosClient client, String bucketName, String objectKey) {
 // Delete Object
 client.deleteObject(＜BucketName＞, ＜ObjectKey＞);   //Specify the name of the bucket where the object to be deleted is located and the name of the object
}

Delete multiple files

You can refer to the following two methods to delete multiple objects:

                Java
                
            

                // 1. In the form of a Json string
String jsonObjectKeys = "{\"objects\": ["+"{\"key\": \"token1.h\"},"+"{\"key\": \"token2.h\"}"+"]}";
DeleteMultipleObjectsRequest request = new DeleteMultipleObjectsRequest();
request.setBucketName("yourBucketName");
request.setJsonDeleteObjects(jsonObjectKeys);
client.deleteMultipleObjects(request);
            

                Java
                
            

                // 2. Users only need to specify the parameters
List<String> objectKeys = new ArrayList<String>();
objectKeys.add("object1");
objectKeys.add("object2");
DeleteMultipleObjectsRequest request = new DeleteMultipleObjectsRequest();
request.setBucketName("yourBucketName");
request.setObjectKeys(objectKeys);
DeleteMultipleObjectsResponse response = client.deleteMultipleObjects(request);
            

1,000 objects can be deleted at most via a single request. The message body (body) does not exceed 2 M. The returned message body only includes erroneous object results in the deletion process; no message body is returned if all objects are deleted successfully.
