Deleting Objects

If you have any questions during development, post them on the Issues page of GitHub.

Exercise caution when performing this operation. If the versioning function is disabled for the bucket where the object is located, the object cannot be restored after being deleted.

Sample code:

static void test_delete_object(char *key, char *version_id, char *bucket_name)
{
    obs_status ret_status = OBS_STATUS_BUTT;

    // Create and initialize object information.
    obs_object_info object_info;
    memset(&object_info, 0, sizeof(obs_object_info));
    object_info.key = key;
    // Create and initialize option.
    obs_options option;
    init_obs_options(&option);
    option.bucket_options.host_name = "<your-endpoint>";
    option.bucket_options.bucket_name = "<Your bucketname>";

    // Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables ACCESS_KEY_ID and SECRET_ACCESS_KEY.
    // Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
    option.bucket_options.access_key = getenv("ACCESS_KEY_ID");
    option.bucket_options.secret_access_key = getenv("SECRET_ACCESS_KEY");
    
    // Set response callback function.
    obs_response_handler resqonseHandler =
    { 
        &response_properties_callback,
        &response_complete_callback 
    };
    
    // Delete an object.
    delete_object(&option,&object_info,&resqonseHandler, &ret_status);
    if (OBS_STATUS_OK == ret_status) 
    {
        printf("delete object successfully. \n");
    }
    else
    {
        printf("delete object failed(%s).\n", obs_get_status_name(ret_status));
    }
}

The parameters are as follows:

Sample code:

static void test_batch_delete_objects()
{ 
    obs_status ret_status = OBS_STATUS_BUTT;

    // Create and initialize option.
    obs_options option;
    init_obs_options(&option);

    option.bucket_options.host_name = "<your-endpoint>";
    option.bucket_options.bucket_name = "<Your bucketname>";

    // Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
    option.bucket_options.access_key = getenv("ACCESS_KEY_ID");
    option.bucket_options.secret_access_key = getenv("SECRET_ACCESS_KEY");

    // Initialize information of the objects to be deleted.
    obs_object_info objectinfo[100];
    objectinfo[0].key = "obj1";
    objectinfo[0].version_id = "versionid1";
    objectinfo[1].key = "obj2";
    objectinfo[1].version_id = "versionid2";

    obs_delete_object_info delobj;
    memset_s(&delobj,sizeof(obs_delete_object_info),0,sizeof(obs_delete_object_info));
    delobj.keys_number = 2;

    // Set response callback function.
    obs_delete_object_handler handler =
    { 
        {&response_properties_callback, &response_complete_callback},
        &delete_objects_data_callback
    };

    // Delete objects in batches.
    batch_delete_objects(&option, objectinfo, &delobj, 0, &handler, &ret_status);
    if (OBS_STATUS_OK == ret_status) {
        printf("test batch_delete_objects successfully. \n");
    }
    else
    {
        printf("test batch_delete_objects faied(%s).\n", obs_get_status_name(ret_status));
    }
