    Setting a Lifecycle Configuration

    Description

    This API is used to set the lifecycle configuration 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";
    PutBucketLifecycleRequest putBucketLifecycleRequest =
    new PutBucketLifecycleRequest(bucket);
    
    // Specify a lifecycle configuration rule
    LifecycleConfiguration.Rule rule = new LifecycleConfiguration.Rule();
    rule.id = "Lifecycle ID";
    LifecycleConfiguration.Filter filter = new LifecycleConfiguration.Filter();
    // Specify the prefix to which the rule applies
    filter.prefix = "dir/";
    rule.filter = filter;
    // Specify whether to enable the rule
    rule.status = "Enabled";
    // Specify the number of days after which the object is last modified that the action in the rule will be performed
    LifecycleConfiguration.Transition transition =
    new LifecycleConfiguration.Transition();
    transition.days = 100;
    transition.storageClass = COSStorageClass.STANDARD.getStorageClass();
    rule.transition = transition;
    
    putBucketLifecycleRequest.setRuleList(rule);
    
    cosXmlService.putBucketLifecycleAsync(putBucketLifecycleRequest,
    new CosXmlResultListener() {
    @Override
    public void onSuccess(CosXmlRequest request, CosXmlResult result) {
    PutBucketLifecycleResult putBucketLifecycleResult =
    (PutBucketLifecycleResult) 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 a Lifecycle Configuration

    Description

    This API is used to query the lifecycle management configuration of a 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";
    GetBucketLifecycleRequest getBucketLifecycleRequest =
    new GetBucketLifecycleRequest(bucket);
    
    cosXmlService.getBucketLifecycleAsync(getBucketLifecycleRequest,
    new CosXmlResultListener() {
    @Override
    public void onSuccess(CosXmlRequest request, CosXmlResult result) {
    GetBucketLifecycleResult getBucketLifecycleResult =
    (GetBucketLifecycleResult) 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 a Lifecycle Configuration

    Description

    This API is used to delete the lifecycle management configuration of a 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";
    DeleteBucketLifecycleRequest deleteBucketLifecycleRequest =
    new DeleteBucketLifecycleRequest(bucket);
    
    cosXmlService.deleteBucketLifecycleAsync(deleteBucketLifecycleRequest,
    new CosXmlResultListener() {
    @Override
    public void onSuccess(CosXmlRequest request, CosXmlResult result) {
    DeleteBucketLifecycleResult deleteBucketLifecycleResult =
    (DeleteBucketLifecycleResult) 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();
    }
    }
