授权数据集访问另一个数据集

在Python中，我们可以使用AWS SDK（或boto3）来解决此问题。具体而言，我们需要使用以下代码的两个数据集之间的IAM角色进行互联，并将其中一个数据集授权给访问另一个数据集：

import boto3

client = boto3.client('sts')
account_id = client.get_caller_identity()['Account']

cross_account_role_name = 'CrossAccountRoleName' # The IAM role name in the other AWS account
cross_account_account_id = 'OtherAWSAccountId' # The AWS account ID where the other IAM role is defined

cross_account_role_arn = 'arn:aws:iam::' + cross_account_account_id + ':role/' + cross_account_role_name
cross_account_session = boto3.Session(profile_name='default', region_name='us-west-2')
sts = cross_account_session.client('sts')
assumed_role = sts.assume_role(RoleArn=cross_account_role_arn, RoleSessionName='CrossAccountRoleSession')
credentials = assumed_role['Credentials']

s3 = boto3.resource('s3', region_name='us-west-2', aws_access_key_id=credentials['AccessKeyId'], aws_secret_access_key=credentials['SecretAccessKey'], aws_session_token=credentials['SessionToken'])

intended_dataset_bucket_name = 'IntendedDatasetBucketName'
intended_dataset_prefix = 'IntendedDatasetPrefix'

intended_dataset = s3.Bucket(intended_dataset_bucket_name).Object(intended_dataset_prefix)

source_dataset_bucket_name = 'SourceDatasetBucketName'
source_dataset_prefix = 'SourceDatasetPrefix'

source_dataset = s3.Bucket(source_dataset_bucket_name).Object(source_dataset_prefix)

intended_dataset.Acl().put(ACL='log-delivery-write', AccessControlPolicy={
    'Grants': [
        {
            'Grantee': {
                'DisplayName': 'Name',
                'ID': 'Canonical ID',
                'Type': 'CanonicalUser',
            },
            'Permission': 'FULL_CONTROL',
        },
        {
            'Grantee': {
                'ID': 'AWS account ID',  # Other AWS account ID
                'Type': 'CanonicalUser',
            },
            'Permission': 'READ',
        },
    ],
    'Owner': {
        'DisplayName': 'Bucket Owner Name',
        'ID': 'Canonical ID',
    },
})

在上述代码中，我们首先假定了IAM角色。然后，使用Session和client对象创建的STS客户机来假定访问另一个AWS账户中的IAM角色。最后，以编程方式向我们想要授权访问的数据集添加ACL条目。该ACL允许
