Deleting an Object

Function

This API deletes objects from a specific bucket.

Restrictions

• To delete an object, you must be the bucket owner or have the required permission (obs:object:DeleteObject in IAM or DeleteObject in a bucket policy).

• If versioning is not enabled for a bucket, deleted objects cannot be recovered.

Method

obsClient.deleteObject(DeleteObjectRequest request)

Request Parameters

Table 1 List of request parameters

Parameter	Type	Mandatory (Yes/No)	Description
request	DeleteObjectRequest	Yes	Explanation: Request parameters for deleting an object. For details, see Table 2.

Table 2 DeleteObjectRequest

Parameter	Type	Mandatory (Yes/No)	Description
bucketName	String	Yes	Explanation: Bucket name. Restrictions: A bucket name must be unique across all accounts and regions. A bucket name: Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed. Cannot be formatted as an IP address. Cannot start or end with a hyphen (-) or period (.). Cannot contain two consecutive periods (..), for example, my..bucket. Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket. If you repeatedly create buckets of the same name in the same region, no error will be reported and the bucket attributes comply with those set in the first creation request. Default value: None
objectKey	String	Yes	Explanation: Object name. An object is uniquely identified by an object name in a bucket. An object name is a complete path that does not contain the bucket name. Value range: The value must contain 1 to 1,024 characters. Default value: None
versionId	String	No	Explanation: Object version ID. Value range: The value must contain 32 characters. Default value: None

Responses

Table 3 DeleteObjectResult

Parameter	Type	Description
statusCode	int	Explanation: HTTP status code. Value range: A status code is a group of digits that can be 2xx (indicating successes) or 4xx or 5xx (indicating errors). It indicates the status of a response. Default value: None
responseHeaders	Map<String, Object>	Explanation: Response header list, composed of tuples. In a tuple, the String key indicates the name of the header, and the Object value indicates the value of the header. Default value: None
versionId	String	Explanation: Object version ID. Value range: The value must contain 32 characters. Default value: None
deleteMarker	boolean	Explanation: Whether the deleted object is a delete marker. Value range: true: The deleted object is a delete marker. false: The deleted object is not a delete marker. Default value: false
objectKey	String	Explanation: Object name. An object is uniquely identified by an object name in a bucket. An object name is a complete path that does not contain the bucket name. Value range: The value must contain 1 to 1,024 characters. Default value: None

Code Examples

This example deletes object objectname from bucket examplebucket.

import com.obs.services.ObsClient;
import com.obs.services.exception.ObsException;
public class DeleteObject001 {
    public static void main(String[] args) {
        // Obtain an AK/SK pair using environment variables or import the AK/SK pair in other ways. Using hard coding may result in leakage.
        // Obtain an AK/SK pair on the management console.
        String ak = System.getenv("ACCESS_KEY_ID");
        String sk = System.getenv("SECRET_ACCESS_KEY_ID");
        // (Optional) If you are using a temporary AK/SK pair and a security token to access OBS, you are advised not to use hard coding, which may result in information leakage.
        // Obtain an AK/SK pair and a security token using environment variables or import them in other ways.
        // String securityToken = System.getenv("SECURITY_TOKEN");
        // Enter the endpoint corresponding to the region where the bucket is to be created.
        String endPoint = "https://your-endpoint";
        // Obtain an endpoint using environment variables or import it in other ways.
        //String endPoint = System.getenv("ENDPOINT");

        // Create an ObsClient instance.
        // Use the permanent AK/SK pair to initialize the client.
        ObsClient obsClient = new ObsClient(ak, sk,endPoint);
        // Use the temporary AK/SK pair and security token to initialize the client.
        // ObsClient obsClient = new ObsClient(ak, sk, securityToken, endPoint);

        try {
            // Delete the object.
            obsClient.deleteObject("examplebucket", "objectname");
            System.out.println("deleteObject successfully");
        } catch (ObsException e) {
            System.out.println("deleteObject failed");
            // Request failed. Print the HTTP status code.
            System.out.println("HTTP Code:" + e.getResponseCode());
            // Request failed. Print the server-side error code.
            System.out.println("Error Code:" + e.getErrorCode());
            // Request failed. Print the error details.
            System.out.println("Error Message:" + e.getErrorMessage());
            // Request failed. Print the request ID.
            System.out.println("Request ID:" + e.getErrorRequestId());
            System.out.println("Host ID:" + e.getErrorHostId());
            e.printStackTrace();
        } catch (Exception e) {
            System.out.println("deleteObject failed");
            // Print other error information.
            e.printStackTrace();
        }
    }
}
