Copying an Object Version

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.

You can call ObsClient.CopyObject to copy an object version by specifying the version ID (SourceVersionId).

This example specifies SourceVersionId to copy sourceobjectname from sourcebucketname to destbucketname as destobjectname.

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);
// Copy an object version.
try
{
    CopyObjectRequest request = new CopyObjectRequest();
    request.SourceBucketName = "sourcebucketname";
    request.SourceObjectKey = "sourceobjectname";
    request.BucketName = "destbucketname";
    request.ObjectKey = "destobjectName";
    request.SourceVersionId = "sourceversionId";
    CopyObjectResponse response = client.CopyObject(request);
    Console.WriteLine("copy object response: {0}", response.StatusCode);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}
