    Setting Cross-region Replication Rules

    Description

    This API is used to set the cross-region replication rules of a specified bucket.

    Sample code

    // Bucket name in the format of BucketName-APPID (APPID is required), which can be viewed in the COS console at https://console.tencentcloud.com/cos5/bucket
    String bucket = "examplebucket-1250000000";
    PutBucketReplicationRequest putBucketReplicationRequest =
    new PutBucketReplicationRequest(bucket);
    
    string ownerUin = "100000000001"; //Replication initiator identifier: OwnerUin
    string subUin = "100000000001"; //Replication initiator identifier: SubUin
    putBucketReplicationRequest.setReplicationConfigurationWithRole(ownerUin,
    subUin);
    
    PutBucketReplicationRequest.RuleStruct ruleStruct =
    new PutBucketReplicationRequest.RuleStruct();
    // Identify the name of a specific rule
    ruleStruct.id = "replication_01";
    //Identify whether to enable the rule. true: enabled; false: disabled
    ruleStruct.isEnable = true;
    // Destination bucket region
    ruleStruct.region = "ap-beijing";
    // Destination bucket
    ruleStruct.bucket = "destinationbucket-1250000000";
    // Prefix matching policy
    ruleStruct.prefix = "dir/";
    putBucketReplicationRequest.setReplicationConfigurationWithRule(ruleStruct);
    
    cosXmlService.putBucketReplicationAsync(putBucketReplicationRequest,
    new CosXmlResultListener() {
    @Override
    public void onSuccess(CosXmlRequest request, CosXmlResult result) {
    PutBucketReplicationResult putBucketReplicationResult =
    (PutBucketReplicationResult) result;
    }
    
    // If you use the Kotlin language to call this, please note that the exception in the callback method is nullable; otherwise, the onFail method will not be called back, that is:
    // clientException is of type CosXmlClientException? and serviceException is of type CosXmlServiceException?
    @Override
    public void onFail(CosXmlRequest cosXmlRequest,
    @Nullable CosXmlClientException clientException,
    @Nullable CosXmlServiceException serviceException) {
    if (clientException != null) {
    clientException.printStackTrace();
    } else {
    serviceException.printStackTrace();
    }
    }
    });

    Querying Cross-region Replication Rules

    Description

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

    Sample code

    // Bucket name in the format of BucketName-APPID (APPID is required), which can be viewed in the COS console at https://console.tencentcloud.com/cos5/bucket
    String bucket = "examplebucket-1250000000";
    GetBucketReplicationRequest getBucketReplicationRequest =
    new GetBucketReplicationRequest(bucket);
    
    cosXmlService.getBucketReplicationAsync(getBucketReplicationRequest,
    new CosXmlResultListener() {
    @Override
    public void onSuccess(CosXmlRequest request, CosXmlResult result) {
    GetBucketReplicationResult getBucketReplicationResult =
    (GetBucketReplicationResult) result;
    }
    
    // If you use the Kotlin language to call this, please note that the exception in the callback method is nullable; otherwise, the onFail method will not be called back, that is:
    // clientException is of type CosXmlClientException? and serviceException is of type CosXmlServiceException?
    @Override
    public void onFail(CosXmlRequest cosXmlRequest,
    @Nullable CosXmlClientException clientException,
    @Nullable CosXmlServiceException serviceException) {
    if (clientException != null) {
    clientException.printStackTrace();
    } else {
    serviceException.printStackTrace();
    }
    }
    });

    Deleting Cross-region Replication Rules

    Description

    This API is used to delete the cross-region replication rules of a specified bucket.

    Sample code

    // Bucket name in the format of BucketName-APPID (APPID is required), which can be viewed in the COS console at https://console.tencentcloud.com/cos5/bucket
    String bucket = "examplebucket-1250000000";
    DeleteBucketReplicationRequest deleteBucketReplicationRequest =
    new DeleteBucketReplicationRequest(bucket);
    
    cosXmlService.deleteBucketReplicationAsync(deleteBucketReplicationRequest,
    new CosXmlResultListener() {
    @Override
    public void onSuccess(CosXmlRequest request, CosXmlResult result) {
    DeleteBucketReplicationResult deleteBucketReplicationResult =
    (DeleteBucketReplicationResult) result;
    }
    
    // If you use the Kotlin language to call this, please note that the exception in the callback method is nullable; otherwise, the onFail method will not be called back, that is:
    // clientException is of type CosXmlClientException? and serviceException is of type CosXmlServiceException?
