AWS Boto3是AWS的Python SDK,可以用于与AWS服务进行编程交互。在运行代码之前,需要确保具有足够的权限来访问所需的AWS服务。以下是如何查看代码成功运行所需的权限的步骤:
import boto3
from botocore.exceptions import ClientError
session = boto3.Session(profile_name='profile_name')
s3_client = session.client('s3')
bucket_name = 'my-bucket'
try:
response = s3_client.list_objects(Bucket=bucket_name)
except ClientError as e:
if e.response['Error']['Code'] == 'AccessDenied':
print(f"Access denied. You don't have permission to list objects in {bucket_name}.")
elif e.response['Error']['Code'] == 'NoSuchBucket':
print(f"The {bucket_name} bucket does not exist.")
else:
print(e)
else:
print(f"Objects in {bucket_name}:")
for content in response.get("Contents", []):
print(f"\t{content['Key']}")
如果执行此代码所需的权限不足,则会引发“AccessDenied”异常。在这种情况下,可以根据异常的错误代码确定缺少的权限。如果此代码需要的权限配置在IAM策略中,请确保分配给当前IAM用户的策略包含所需的权限。
