Configuring or Obtaining Bucket Storage Quota

If you have any questions during the development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

Configuring Bucket Storage Quota

You can call ObsClient.SetBucketQuota to configure bucket storage quota. The sample code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK before storing them in the configuration file or environment variables. In this example, the AK and SK are stored in environment variables. Before running the code in this example, configure environment variables AccessKeyID and SecretAccessKey.
// 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.
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);
// Configure bucket storage quota.
try
{
    SetBucketQuotaRequest request = new SetBucketQuotaRequest
    {
        BucketName = "bucketname",
        StorageQuota = 0L,
    };
    SetBucketQuotaResponse response = client.SetBucketQuota(request);
    Console.WriteLine("Set bucket quota response: {0}", response.StatusCode);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}

A bucket quota must be a non-negative integer expressed in bytes. The maximum value is 263 - 1.

Obtaining Bucket Storage Quota

You can call ObsClient.GetBucketQuota to obtain bucket storage quota. The sample code is as follows:

// Initialize configuration parameters.
ObsConfig config = new ObsConfig();
config.Endpoint = "https://your-endpoint";
// Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK before storing them in the configuration file or environment variables. In this example, the AK and SK are stored in environment variables. Before running the code in this example, configure environment variables AccessKeyID and SecretAccessKey.
// 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.
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);
// Obtain bucket storage quota.
try
{
    GetBucketQuotaRequest request = new GetBucketQuotaRequest
    {
        BucketName = "bucketname",
    };
    GetBucketQuotaResponse response = client.GetBucketQuota(request);
    Console.WriteLine("Get bucket quota response: {0}", response.StatusCode);
    Console.WriteLine("StorageQuota: {0}", response.StorageQuota);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}
