Obtaining Bucket Location

Functions

This API is used to obtain the region information about a specified bucket.

You are advised to use the API in Obtaining Bucket Metadata to obtain the bucket location.

Calling Method

For details, see Calling APIs. Before calling this API, calculate the API signature and add it to the request.

Authorization Information

To call this API, you must be the bucket owner or have the permission to obtain the bucket location. You are advised to use IAM or bucket policies for authorization. For details about OBS authorization methods, see Differences Between OBS Permissions Control Methods.

• If you use IAM for authorization, you need to use either role/policy-based authorization or identity policy-based authorization and configure the required permissions:
  • If you use role/policy-based authorization (IAM v3 APIs in the old IAM version), you need to grant the obs:bucket:GetBucketLocation permission. For details, see Creating a Custom IAM Policy.
  • If you use identity policy-based authorization (IAM v5 APIs in the new IAM version), you need to grant the obs:bucket:getBucketLocation permission, as shown in the following table. For details, see Creating a Custom IAM Identity Policy.

    Action	Access Level	Resource Type (*: Required)	Condition Key	Alias	Dependencies
    obs:bucket:getBucketLocation	Read	bucket *	g:EnterpriseProjectId g:ResourceTag/<tag-key>	-	-
    		-	obs:EpochTime obs:SourceIp obs:TlsVersion obs:CustomDomain

• If you use bucket policies for authorization, you need to grant the obs:bucket:GetBucketLocation permission. For details, see Creating a Custom Bucket Policy.
