如何使用 Boto3 和 AWS 客户端获取 S3 桶的通知配置详细信息?
问题陈述 − 使用 Python 中的 boto3 库获取 S3 桶的通知配置。例如,查找 S3 中 Bucket_1 的通知配置详细信息。
解决此问题的方法/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。
步骤 4 − 为 S3 创建 AWS 客户端。
步骤 5 − 现在使用函数 get_bucket_notification_configuration 并传递桶名称。
步骤 6 − 它返回包含有关 S3 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 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
{ 'TopicConfigurations': [ { 'Id': 'string', 'TopicArn': 'string', 'Events': [ 's3:ReducedRedundancyLostObject'|'s3:ObjectCreated:*'|'s3:ObjectCreated: Put'|'s3:ObjectCreated:Post'|'s3:ObjectCreated:Copy'|'s3:ObjectCreated:C ompleteMultipartUpload'|'s3:ObjectRemoved:*'|'s3:ObjectRemoved:Delete'|' s3:ObjectRemoved:DeleteMarkerCreated'|'s3:ObjectRestore:*'|'s3:ObjectRes tore:Post'|'s3:ObjectRestore:Completed'|'s3:Replication:*'|'s3:Replicati on:OperationFailedReplication'|'s3:Replication:OperationNotTracked'|'s3: Replication:OperationMissedThreshold'|'s3:Replication:OperationReplicate dAfterThreshold', ], 'Filter': { 'Key': { 'FilterRules': [ { 'Name': 'prefix'|'suffix', 'Value': 'string' }, ] } } }, ], 'QueueConfigurations': [ { 'Id': 'string', 'QueueArn': 'string', 'Events': [ 's3:ReducedRedundancyLostObject'|'s3:ObjectCreated:*'|'s3:ObjectCreated: Put'|'s3:ObjectCreated:Post'|'s3:ObjectCreated:Copy'|'s3:ObjectCreated:C ompleteMultipartUpload'|'s3:ObjectRemoved:*'|'s3:ObjectRemoved:Delete'|' s3:ObjectRemoved:DeleteMarkerCreated'|'s3:ObjectRestore:*'|'s3:ObjectRes tore:Post'|'s3:ObjectRestore:Completed'|'s3:Replication:*'|'s3:Replicati on:OperationFailedReplication'|'s3:Replication:OperationNotTracked'|'s3: Replication:OperationMissedThreshold'|'s3:Replication:OperationReplicate dAfterThreshold', ], 'Filter': { 'Key': { 'FilterRules': [ { 'Name': 'prefix'|'suffix', 'Value': 'string' }, ] } } }, ], 'LambdaFunctionConfigurations': [ { 'Id': 'string', 'LambdaFunctionArn': 'string', 'Events': [ 's3:ReducedRedundancyLostObject'|'s3:ObjectCreated:*'|'s3:ObjectCreated: Put'|'s3:ObjectCreated:Post'|'s3:ObjectCreated:Copy'|'s3:ObjectCreated:C ompleteMultipartUpload'|'s3:ObjectRemoved:*'|'s3:ObjectRemoved:Delete'|' s3:ObjectRemoved:DeleteMarkerCreated'|'s3:ObjectRestore:*'|'s3:ObjectRes tore:Post'|'s3:ObjectRestore:Completed'|'s3:Replication:*'|'s3:Replicati on:OperationFailedReplication'|'s3:Replication:OperationNotTracked'|'s3: Replication:OperationMissedThreshold'|'s3:Replication:OperationReplicate dAfterThreshold', ], 'Filter': { 'Key': { 'FilterRules': [ { 'Name': 'prefix'|'suffix', 'Value': 'string' }, ] } } }, ] }
注意:此输出取决于桶的设置/权限。如果某些设置/权限为默认值或未设置,则会忽略结果。类似地,如果未为桶设置通知,则它返回 NONE。
