Object Storage Service:Query the region of a bucket using OSS SDK for Python 1.0

Prerequisites

Before you begin, make sure that you have:

• Configured the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables with your access credentials

• Granted the oss:GetBucketLocation permission to the account. For details, see Attach a custom policy to a RAM user

To access OSS from other Alibaba Cloud services in the same region, use an internal endpoint instead of the public endpoint used in the sample code below. For the full list of regions and endpoints, see Regions and endpoints.

Get the bucket region

The following example uses ProviderAuthV4 with environment variable credentials and calls get_bucket_location() to get the region. The region parameter is required for V4 signatures.

# -*- coding: utf-8 -*-
import oss2
from oss2.credentials import EnvironmentVariableCredentialsProvider

# Load access credentials from environment variables:
# OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET
auth = oss2.ProviderAuthV4(EnvironmentVariableCredentialsProvider())

# Endpoint of the region where the bucket is located.
# Example: China (Hangzhou) -> https://oss-cn-hangzhou.aliyuncs.com
endpoint = "https://oss-cn-hangzhou.aliyuncs.com"

# Region ID -- required for V4 signatures.
region = "cn-hangzhou"

bucket = oss2.Bucket(auth, endpoint, "yourBucketName", region=region)

# Get the bucket region.
result = bucket.get_bucket_location()
print('location: ' + result.location)
