This document provides the SDK code samples to determine whether an object exists.
This API is used to check whether an object exists in a bucket.

If you need to debug, you can set it to DEBUG and the SDK will print the communication information of the client. logging.basicConfig(level=logging.INFO, stream=sys.stdout) # 1.

|Bucket||Bucket name in the format of
|Key||Object key, which uniquely identifies an object in a bucket. For example, if an object's access endpoint is
True means the object exists, while
False means the object does not exist.
