您好，我正在使用S3开发程序，但是有问题

botocore.vendored.requests.exceptions.SSLError错误，当我尝试使用Boto3从S3下载数据时出现

当另一台服务器使用相同的代码时，它可以工作。并且在同一台服务器（boto3发生故障的服务器）上使用aws cli时可以使用。

我不知道该怎么解决。

请帮助我。谢谢。

对于任何boto3.Session.client或boto3.Session.resource对象，您可以传递verify=False参数以跳过SSL证书验证。例如，当您创建客户端或资源时，请执行以下操作：

import boto3

boto3_session = boto3.Session(profile_name=some_profile_you_configured)

s3_resource = boto3_session.resource(service_name='s3', verify=False)
s3_client = boto3_session.client(service_name='s3', verify=False)

[insert your code here using the s3_resource or s3_client objects]

boto3 documentation是您最好的朋友。
