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。例如，在S3中查找Bucket_1的通知配置详细信息。

解决该问题的方法/算法

步骤1 - 导入Boto3和Botocore异常以处理异常。

步骤2 - 使用bucket_name作为函数参数。

步骤3 - 使用Boto3库创建AWS会话。

步骤4 - 创建用于S3的AWS客户端。

步骤5 - 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
from botocore.exceptions import 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

注意： 此输出取决于存储桶的设置/权限。如果某些设置/权限是默认值或未设置，则它将省略结果。类似地，如果未为存储桶设置通知，则返回“NONE”。
