问cos上传文件设置生命周期？

给cos桶putBucketLifecycle设置生命周期，设置成功后返回=====================

Debug output of model

=====================

Model data

-----------

This data can be retrieved from the model object using the get() method of the model (e.g. $model->get($key)) or accessing the model like an associative array (e.g. $model['key']). 同时getBucketLifecycle查询生命周期结果返回的规则为空，这是为啥？求解
