SDK API Reference

For the parameters and method descriptions of all the APIs in the SDK, please see SDK API Reference.

Deleting a Single Object

Feature description

This API is used to delete a specified object.

Sample code

String bucket = "examplebucket-1250000000"; // Bucket name in the format: `BucketName-APPID`
String cosPath = "exampleobject"; // Location identifier of the object in the bucket, i.e., the object key

DeleteObjectRequest deleteObjectRequest = new DeleteObjectRequest(bucket,
        cosPath);
cosXmlService.deleteObjectAsync(deleteObjectRequest,
        new CosXmlResultListener() {
    @Override
    public void onSuccess(CosXmlRequest cosXmlRequest, CosXmlResult result) {
        DeleteObjectResult deleteObjectResult = (DeleteObjectResult) result;
    }

    @Override
    public void onFail(CosXmlRequest cosXmlRequest,
                       CosXmlClientException clientException,
                       CosXmlServiceException serviceException) {
        if (clientException != null) {
            clientException.printStackTrace();
        } else {
            serviceException.printStackTrace();
        }
    }
});

Deleting Multiple Objects

Feature description

This API is used to delete multiple objects in a single request.

Sample code

String bucket = "examplebucket-1250000000"; // Bucket name in the format: `BucketName-APPID`
List<String> objectList = new ArrayList<String>();
objectList.add("exampleobject1"); // Location identifier of the object in the bucket, i.e., the object key
objectList.add("exampleobject2"); // Location identifier of the object in the bucket, i.e., the object key

DeleteMultiObjectRequest deleteMultiObjectRequest =
        new DeleteMultiObjectRequest(bucket, objectList);
// In quiet mode, only information on objects that failed to be deleted will be returned; otherwise, the deletion result of each object will be returned.
deleteMultiObjectRequest.setQuiet(true);
cosXmlService.deleteMultiObjectAsync(deleteMultiObjectRequest,
        new CosXmlResultListener() {
    @Override
    public void onSuccess(CosXmlRequest cosXmlRequest, CosXmlResult result) {
        DeleteMultiObjectResult deleteMultiObjectResult =
                (DeleteMultiObjectResult) result;
    }

    @Override
    public void onFail(CosXmlRequest cosXmlRequest,
                       CosXmlClientException clientException,
                       CosXmlServiceException serviceException) {
        if (clientException != null) {
            clientException.printStackTrace();
        } else {
            serviceException.printStackTrace();
        }
    }
});
