   object_id 在云存储中不存在的时候，会返回一个本地构造的 object，可以通过 created_at 是否被设置来察觉到。
   当前我们自己的项目里做了这样的 patch：

   from leancloud import Query as OriginalQuery
   
   
   class Query(OriginalQuery):
       def get(self, object_id):
           obj = super().get(object_id)
   
           # 此处也可以 raise 101，大家可以按自己的习惯来
           return obj if getattr(obj, "created_at", None) else None
   
   
   def patch_leancloud():
       import leancloud
   
       leancloud.Query = Query

   是的，其实 SDK 提供了一个 is_existed 方法（这个方法在实现上也是检查 created_at）
