def main():
    with open('S3.csv', 'w') as csvfile:
        writer = csv.writer(csvfile)
        writer.writerow([
            'Account Name',
            'Region',
            'Bucket Name',
            'Policy'

        ])
        with open('role.json') as ec2_file:
            ec2_data = json.load(ec2_file)
        region_list = ['eu-west-1']
        for region in region_list:
            for index in range(len(ec2_data['Items'])):
                Account_Number = ec2_data['Items'][index]['Aws_Account_Number']
                Account_Name = ec2_data['Items'][index]['Acc_Name']
                ARN = ec2_data['Items'][index]['ARN']
                b = get_assume_arn_to_keys(Account_Number,Account_Name,ARN)
                ds_client = boto3.client('s3',region_name=region,aws_access_key_id=``,aws_secret_access_key=``,aws_session_token=``)


                s3 = boto3.resource('s3')

                for bucket in s3.buckets.all():
                    writer.writerow([
                        Account_Name,
                        region,
                        bucket.name,
                        ds_client.get_bucket_lifecycle(Bucket=bucket.name)

main()

我想在.csv中列出s3存储桶及其生命周期策略。我可以列出所有存储桶。

但是，列出生命周期策略会给我带来问题。我无法列出所有存储桶。可能，这只是给我第一个桶的政策。

如果我直接输入存储桶名称，我就能获得生命周期策略。所有存储桶中均列出了单个存储桶“ k”策略。

ds_client.get_bucket_lifecycle(Bucket='k')

但是，如果我想全力以赴，我尝试了

ds_client.get_bucket_lifecycle(Bucket=bucket.name)

编辑：：：尝试列出日志记录，区域和版本控制的新方法。

import boto3
s3_client = boto3.client('s3')

bucket_list = ds_client.list_buckets()

for bucket in bucket_list['Buckets']:
    try:
        lifecycle = ds_client.get_bucket_lifecycle(Bucket=bucket['Name'])
        rules = lifecycle['Rules']
    except:
        rules = 'No Policy'                 
    versioning = ds_client.get_bucket_versioning(Bucket=bucket['Name'])
    logging = ds_client.get_bucket_logging(Bucket=bucket['Name'])
    print(bucket['Name'], rules, versioning, logging)

但是无法理解。友善的建议。谢谢

尝试针对没有没有策略的存储桶检索生命周期策略会导致异常。

因此，您将需要像这样使用try/except：

import boto3

s3 = boto3.resource('s3')

for bucket in s3.buckets.all():
    try:
        rules = bucket.Lifecycle().rules
    except:
        rules = 'No Policy'
    print(bucket.name, rules)

或客户端版本：

import boto3

s3_client = boto3.client('s3')

bucket_list = s3_client.list_buckets()

for bucket in bucket_list['Buckets']:

    try:
        lifecycle = s3_client.get_bucket_lifecycle(Bucket=bucket['Name'])
        rules = lifecycle['Rules']
    except:
        rules = 'No Policy'
    print(bucket['Name'], rules)

.csv中的S3存储桶列表及其生命周期策略
