使用boto3从所有区域中检索清单

Question

试图使用boto3从所有区域中检索清单

我 无 我也尝试了以下内容，但它不起作用。

感谢任何帮助，谢谢

if client.head_bucket(Bucket=bucket['Name'])['ResponseMetadata']['HTTPHeaders']['x-amz-bucket-region'] == 'us-east-1':
                print ("bucketname %s " % s3_bucket.name)

代码

import json
import boto3

bucketlist = []

def lambda_handler(event, context):

    # Get list of regions
    ec2 = boto3.client('ec2')
    regions = ec2.describe_regions().get('Regions',[] )

    # Iterate over regions
    for region in regions:
    
        print ("*************** Checking region  --   %s " % region['RegionName'])
        reg=region['RegionName']
    
        client = boto3.client('s3', region_name=reg)

        response = client.list_buckets()
        for bucket in response['Buckets']:
            s3 = boto3.resource('s3', region_name=reg)
            s3_bucket = s3.Bucket(bucket['Name'])
            if client.head_bucket(Bucket=bucket['Name'])['ResponseMetadata']['HTTPHeaders']['x-amz-bucket-region'] == 'us-east-1':
                print ("bucketname %s " % s3_bucket.name)
                bucketlist.append(s3_bucket)
    return {
        "statusCode": 200
    }

输出： buckets testbucket1和testbucket2仅在中可用us-east-1区域

START RequestId: e22f6ac0-7bb9-4e2b-84d7-5512ce97acfa Version: $LATEST
*************** Checking region  --   eu-north-1 
bucketname testbucket1 
bucketname testbucket2 
*************** Checking region  --   ap-south-1 
bucketname testbucket1 
bucketname testbucket2 
[...]
*************** Checking region  --   us-east-1 
bucketname testbucket1
bucketname testbucket2

预期输出：

您不必更改客户的区域。 list_buckets返回帐户中的所有存储桶，无论它们的位置如何。这就是为什么您可以在代码中为每个区域获得相同的存储桶。

您必须迭代list_buckets结果，然后使用 get_bucket_location 获得水桶的实际位置。例如：

all_buckets = client.list_buckets()

for bucket in all_buckets['Buckets']:
  bucket_bame = bucket["Name"]
  region = client.get_bucket_location(Bucket=bucket_bame)["LocationConstraint"]
  print(bucket_bame, region)
