Viewing CORS Rules

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

You can call get_bucket_cors_configuration() to view CORS rules of a bucket. Sample code is as follows:

Parameter Description

Field	Type	Mandatory or Optional	Description
option	The context of the bucket. For details, see Configuring option.	Mandatory	Bucket parameter
handler	obs_cors_handler *	Mandatory	Callback function
callback_data	void *	Optional	Callback data

Sample Code

static void test_get_cors_config()
{
    obs_options option; 
    obs_status  ret_status = OBS_STATUS_BUTT;
    // Set option.
    init_obs_options(&option);
    option->bucket_options.hostName = "<your-endpoint>";
    option->bucket_options.bucketName = "<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 callback function.
    obs_cors_handler cors_handler_info =
    {
        {&response_properties_callback, &response_complete_callback},
        &get_cors_info_callback
    };
    
    get_bucket_cors_configuration(&option, &cors_handler_info, &ret_status);
    if (OBS_STATUS_OK == ret_status) {
        printf("get_cors_config success.\n");
    }
    else {
        printf("get_cors_config faied(%s).\n", obs_get_status_name(ret_status));
    }
}
