      Setting Cross-Region Replication Rule

      API description

      This API is used to set a cross-region replication rule for a specified bucket.

      Sample code

      String bucket = "examplebucket-1250000000"; // Format: BucketName-APPID
      string ownerUin = "100000000001"; //Replication initiator identifier: OwnerUin
      string subUin = "100000000001"; //Replication initiator identifier: SubUin
      PutBucketReplicationRequest request = new PutBucketReplicationRequest(bucket);
      // Set replication
      PutBucketReplicationRequest.RuleStruct ruleStruct = 
        new PutBucketReplicationRequest.RuleStruct();
      ruleStruct.id = "replication_01"; // Identify the replication rule
      ruleStruct.isEnable = true; // Indicates whether the rule is enabled. true: enabled; false: not enabled
      ruleStruct.appid = "1250000000"; // APPID
      ruleStruct.region = "ap-beijing"; // Destination bucket region
      ruleStruct.bucket = "destinationbucket-1250000000"; // Format: BucketName-APPID
      ruleStruct.prefix = "34"; // Prefix matching policy
      List<PutBucketReplicationRequest.RuleStruct> ruleStructs = 
        new List<PutBucketReplicationRequest.RuleStruct>();
      ruleStructs.Add(ruleStruct);
      request.SetReplicationConfiguration(ownerUin, subUin, ruleStructs);
      
      try
      {
        PutBucketReplicationResult result = cosXml.PutBucketReplication(request);
        Console.WriteLine(result.GetResultInfo());
      }
      catch (COSXML.CosException.CosClientException clientEx)
      {
        Console.WriteLine("CosClientException: " + clientEx);
      }
      catch (COSXML.CosException.CosServerException serverEx)
      {
        Console.WriteLine("CosServerException: " + serverEx.GetInfo());
      }

      Querying Cross-Region Replication Rule

      API description

      This API is used to query the cross-region replication rule of a specified bucket.

      Sample code

      String bucket = "examplebucket-1250000000"; // Format: BucketName-APPID
      GetBucketReplicationRequest request = new GetBucketReplicationRequest(bucket);
      try
      {
        GetBucketReplicationResult result = cosXml.GetBucketReplication(request);
        // Bucket’s cross-region replication configuration
        ReplicationConfiguration conf =  result.replicationConfiguration;
      }
      catch (COSXML.CosException.CosClientException clientEx)
      {
        Console.WriteLine("CosClientException: " + clientEx);
      }
      catch (COSXML.CosException.CosServerException serverEx)
      {
        Console.WriteLine("CosServerException: " + serverEx.GetInfo());
      }
      Note:
      For the complete sample, go to GitHub.

      Deleting Cross-Region Replication Rule

      API description

      This API is used to delete the cross-region replication rule from a specified bucket.

      Sample code

      String bucket = "examplebucket-1250000000"; // Format: BucketName-APPID
      DeleteBucketReplicationRequest request = new DeleteBucketReplicationRequest(bucket);
      try
      {
        DeleteBucketReplicationResult result = cosXml.DeleteBucketReplication(request);
        Console.WriteLine(result.GetResultInfo());
      }
      catch (COSXML.CosException.CosClientException clientEx)
      {
        Console.WriteLine("CosClientException: " + clientEx);
      }
      catch (COSXML.CosException.CosServerException serverEx)
      {
        Console.WriteLine("CosServerException: " + serverEx.GetInfo());
      }
