Renaming an Object or Directory

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

You can call rename_object to change the object name and directory name. This API applies only to parallel file systems (PFSs), instead of object buckets.

static void test_rename_object()
{
    obs_status ret_status = OBS_STATUS_BUTT;
    // Name of the object or directory to be renamed
    char *key = "put_buffer_test";
    // New name
    char *new_key_name = "put_buffer_test_new";
    // 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 response_handler =
    { 
        &response_properties_callback, &response_complete_callback
    };
    // Rename an object.
    rename_object(&option, key, new_key_name, &response_handler,&ret_status);
    if (OBS_STATUS_OK == ret_status) {
        printf("rename_object successfully. \n");
    }
    else
    {
        printf("rename_object failed.\n", obs_get_status_name(ret_status));
    }
}

• rename_object applies only to buckets used as parallel file systems.
• If the object to be renamed does not exist, an error is reported (HTTP status code 404).
