如何使用 Boto3 和 AWS 客户端获取 S3 存储桶的通知配置详细信息？
问题陈述-使用Python中的boto3库获取S3存储桶的通知配置。比如在S3中找到Bucket_1的通知配置细节。
解决这个问题的方法/算法
步骤1-导入boto3和botocore异常以处理异常。
步骤2-使用bucket_name作为函数中的参数。
步骤3-使用boto3库创建AWS会话。
第4步-为S3创建一个AWS客户端。
第5步-现在使用函数get_bucket_notification_configuration并传递存储桶名称。
步骤6-它返回包含有关S3的详细信息的字典。如果未设置通知，则返回NONE
步骤7-如果在删除文件时出现问题，请处理通用异常。
示例
使用以下代码获取通知配置详细信息-
import boto3
frombotocore.exceptionsimport ClientError
def get_bucket_notificationconfiguration_of_s3(bucket_name):
session = boto3.session.Session()
s3_client = session.client('s3')
try:
result = s3_client.get_bucket_notification_configuration(Bucket=bucket_name,)
except ClientError as e:
raise Exception( "boto3 client error in get_bucket_notificationconfiguration_of_s3: " + e.__str__())
except Exception as e:
raise Exception( "Unexpected error in get_bucket_notificationconfiguration_of_s3 function: " + e.__str__())
return result
print(get_bucket_notificationconfiguration_of_s3("Bucket_1"))输出结果{

}注意：此输出取决于存储桶的设置/权限。如果某些设置/权限为默认设置或未设置，则忽略结果。同样，如果未为存储桶设置通知，则返回NONE。
