Configuring Lifecycle Management

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

When uploading an object or initializing a multipart upload, you can directly set the expiration time for the object. Sample code is as follows:

// Create an instance of ObsClient.
ObsClient client = new ObsClient("*** Provide your Access Key ***", "*** Provide your Secret Key ***", "https://your-endpoint");

try
{
    PutObjectRequest request = new PutObjectRequest()
    {
        BucketName = "bucketname",
        ObjectKey = "objectname",
        FilePath = "localfile",// Path of the local file uploaded. The file name must be specified.
        Expires = 30 // When uploading an object, set the object to expire after 30 days.
    };
    PutObjectResponse response = client.PutObject(request);
    Console.WriteLine("put object response: {0}", response.StatusCode);

    InitiateMultipartUploadRequest initiateRequest = new InitiateMultipartUploadRequest
    {
        BucketName = "bucketname",
        ObjectKey = "objectname",
        // When initializing a multipart upload, set the object to expire 60 days after combination.
        Expires = 60
    };

    InitiateMultipartUploadResponse initResponse = client.InitiateMultipartUpload(initiateRequest);
    Console.WriteLine("InitiateMultipartUpload status: {0}", initResponse.StatusCode);
    Console.WriteLine("InitiateMultipartUpload UploadId: {0}", initResponse.UploadId);
}
catch (ObsException ex)
{
    Console.WriteLine("ErrorCode: {0}", ex.ErrorCode);
    Console.WriteLine("ErrorMessage: {0}", ex.ErrorMessage);
}
  • The previous mode specifies the time duration in days after which an object will expire. The OBS server automatically clears expired objects.
  • The object expiration time set in the preceding method takes precedence over the bucket lifecycle rule.
