Sample Code

static void test_get_bucket_tagging()
{
    // 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/eu/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_get_bucket_tagging_handler response_handler = 
    {
         {&response_properties_callback, &get_bucket_tagging_complete_callback}, 
            &get_bucket_tagging_callback
    };
    // Create callback data.
    TaggingInfo tagging_info;
    memset(&tagging_info, 0, sizeof(TaggingInfo));
    tagging_info.ret_status = OBS_STATUS_BUTT;
    // Obtain bucket tags
