Obtaining the Region of a Bucket (SDK for Java)
Function
This API returns the region where a bucket is located.
If you have any questions during development, post them on the Issues page of GitHub.
Restrictions
- To obtain the region of a bucket, you must be the bucket owner or have the required permission (obs:bucket:GetBucketLocation in IAM or GetBucketLocation in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.
- The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.
- When creating a bucket, you can specify its location. For details, see Creating a Bucket.
Method
obsClient.getBucketLocation(String bucketName)
Request Parameters
Parameter |
Type |
Mandatory (Yes/No) |
Description |
---|---|---|---|
bucketName |
String |
Yes |
Explanation: Bucket name. Restrictions:
Default value: None |
Responses
Parameter |
Type |
Description |
---|---|---|
statusCode |
int |
Explanation: HTTP status code. Value range: A status code is a group of digits that can be 2xx (indicating successes) or 4xx or 5xx (indicating errors). It indicates the status of a response. For more information, see Status Code. Default value: None |
responseHeaders |
Map<String, Object> |
Explanation: Response header list, composed of tuples. In a tuple, the String key indicates the name of the header, and the Object value indicates the value of the header. Default value: None |
location |
String |
Explanation: Region where a bucket is located. Restrictions: If the endpoint used is obs.myhuaweicloud.com, this parameter is not required. If any other endpoints are used, this parameter is required. Value range: To learn about valid regions and endpoints, see Regions and Endpoints. An endpoint is the request address for calling an API. Endpoints vary depending on services and regions. To obtain the regions and endpoints, contact the enterprise administrator. Default value: If obs.myhuaweicloud.com is used as the endpoint and no region is specified, cn-north-1 (the CN North-Beijing1 region) is used by default. |
