Viewing CORS Rules

You can call ObsClient.GetBucketCors to view CORS rules of a bucket. Sample code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// 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 AccessKeyID and SecretAccessKey.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/eu/usermanual-ca/ca_01_0003.html.
string accessKey= Environment.GetEnvironmentVariable("AccessKeyID", EnvironmentVariableTarget.Machine);
string secretKey= Environment.GetEnvironmentVariable("SecretAccessKey", EnvironmentVariableTarget.Machine);
// Create an instance of ObsClient.
ObsClient client = new ObsClient(accessKey, secretKey, config);
// View CORS rules.
try
{

    GetBucketCorsRequest request = new GetBucketCorsRequest();
    request.BucketName = "bucketname";
    GetBucketCorsResponse response = client.GetBucketCors(request);
    foreach (CorsRule rule in response.Configuration.Rules)
    {
        Console.WriteLine("rule id is: {0}\n", rule.Id);
        foreach (string allowOrigin in rule.AllowedOrigins)
        {
            Console.WriteLine("allowOrigin is: {0}\n", allowOrigin);
        }
        foreach (string allowHeader in rule.AllowedHeaders)
        {
            Console.WriteLine("allowHeader is: {0}\n", allowHeader);
        }
        foreach (HttpVerb allowMethod in rule.AllowedMethods)
        {
            Console.WriteLine("allowMethod is: {0}\n", allowMethod);
        }
        foreach (string exposeHeader in rule.ExposeHeaders)
        {
            Console.WriteLine("exposeHeader is: {0}\n", exposeHeader);
        }
        Console.WriteLine("rule maxAgeSeconds is: {0}\n", rule.MaxAgeSeconds);

    }
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
