我正在尝试从服务器下载mp3文件，然后使用以下代码上传到Google存储空间
from google.cloud import storage
bucket = storage_client.get_bucket('bucketname')
blob = bucket.blob(uploadKey)
blob.upload_from_filename(flacFileName)
但需要注意的是，下载和上传是多线程的，在某些线程中我得到以下异常
Traceback (most recent call last):

我也得到[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:2178)例外。但是这些例外是不稳定的，如果我不使用多个线程，我也没有这些问题。那么，如何正确地将文件上传到google存储多线程？
我查看了此链接https://github.com/GoogleCloudPlatform/google-cloud-python/issues/1214和此处https://developers.google.com/api-client-library/python/guide/thread_safety，但我无法找到如何使用google-cloud-storage客户端库进行操作的答案。
