Sample Code

static void test_set_bucket_tagging()
{
    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>";

    // 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 =
    { 
        0,
        &response_complete_callback
    };
    // Define the bucket tag.
    char tagKey[][OBS_COMMON_LEN_256] = {{"k1"},{"k2"},{"k3"},{"k4"},{"k5"},{"k6"},{"k7"},{"k8"},{"k9"},{"k10"}};
    char tagValue[][OBS_COMMON_LEN_256] = {{"v1"},{"v2"},{"v3"},{"v4"},{"v5"},{"v6"},{"v7"},{"v8"},{"v9"},{"v10"}};
    obs_name_value tagginglist[10] = {0};
    int i=0;
    for(;i<10;i++)
    {
         tagginglist[i].name = tagKey[i];
         tagginglist[i].value  = tagValue[i];
    } 
    // Set bucket tags.
    set_bucket_tagging(&option, tagginglist, 8, &response_handler, &ret_status);
    if (OBS_STATUS_OK == ret_status) {
        printf("set bucket tagging successfully. \n");
    }
    else
    {
        printf("set bucket tagging failed(%s).\n", obs_get_status_name(ret_status));
    }
