我第一次和boto3玩。我想循环使用s3存储桶填充的数组,然后获取每个存储桶的策略状态,尽管我得到了一个错误,但不确定原因。它适用于数组的第一个索引,但之后会出错。为什么?
#!/usr/bin/python3
import boto3
all_buckets=[]
session = boto3.Session(profile_name='default')
s3 = session.client('s3')
def get_bucket_list():
for i in s3.list_buckets()['Buckets']:
all_buckets.append(f' {i["Name"]}')
get_bucket_list()
for j in all_buckets:
k = (j.strip())
policy = s3.get_bucket_policy_status(Bucket=k)
print(policy)
错误:(注意:对AWS ID的引用不真实)

botocore.exceptions.ClientError: An error occurred (NoSuchBucketPolicy) when calling the GetBucketPolicyStatus operation: The bucket policy does not exist
GetBucketPolicy在没有附加策略时引发异常
因此,我们应该捕获异常,因为不是每个bucket都需要一个bucket策略。可以通过bucket策略或IAM策略控制对bucket的访问
以下是修改后的代码:
