Obtaining the Region of a Bucket

Function

This API returns the region of a bucket.

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).

Method

func (obsClient ObsClient) GetBucketLocation(bucketName string) (output *GetBucketLocationOutput, err error)

Request Parameters

Table 1 List of request parameters

Parameter	Type	Mandatory (Yes/No)	Description
bucketName	string	Yes	Explanation: Bucket name Restrictions: A bucket name must be unique across all accounts and regions. A bucket name: Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed. Cannot be formatted as an IP address. Cannot start or end with a hyphen (-) or period (.). Cannot contain two consecutive periods (..), for example, my..bucket. Cannot contain a period (.) and a hyphen (-) adjacent to each other, for example, my-.bucket or my.-bucket. If you repeatedly create buckets of the same name in the same region, no error will be reported and the bucket attributes comply with those set in the first creation request. Default value: None

Responses

Parameter	Type	Description
output	*GetBucketLocationOutput	Explanation: Returned results. For details, see Table 3.
err	error	Explanation: Error messages returned by the API

Table 3 GetBucketLocationOutput

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. Default value: None
RequestId	string	Explanation: Request ID returned by the OBS server Default value: None
ResponseHeaders	map[string][]string	Explanation: HTTP response headers Default value: None
Location	string	Explanation: Region where a bucket is located 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.

Code Examples

This example returns the region where bucket examplebucket locates.

package main
import (
    "fmt"
    "os"
    "obs-sdk-go/obs"
)
func main() {
    //Obtain an AK/SK pair using environment variables or import an AK/SK pair in other ways. Using hard coding may result in leakage.
    //Obtain an AK/SK pair on the management console.
    ak := os.Getenv("AccessKeyID")
    sk := os.Getenv("SecretAccessKey")
    // (Optional) If you use a temporary AK/SK pair and a security token to access OBS, you are advised not to use hard coding to reduce leakage risks. You can obtain an AK/SK pair using environment variables or import an AK/SK pair in other ways.
    // securityToken := os.Getenv("SecurityToken")
    // Enter the endpoint of the region where the bucket locates.
    endPoint := "https://your-endpoint"
    // Create an obsClient instance.
    // If you use a temporary AK/SK pair and a security token to access OBS, use the obs.WithSecurityToken method to specify a security token when creating an instance.
    obsClient, err := obs.New(ak, sk, endPoint/*, obs.WithSecurityToken(securityToken)*/)
    if err != nil {
        fmt.Printf("Create obsClient error, errMsg: %s", err.Error())
    }
    // Specify a bucket name.
    bucketname := "examplebucket"
    // Obtain the bucket region.
    output, err := obsClient.GetBucketLocation(bucketname)
    if err == nil {
        fmt.Printf("Get bucket(%s)'s location successful!\n", bucketname)
        fmt.Printf("RequestId:%s\n", output.RequestId)
        fmt.Printf("Location:%s\n", output.Location)
        return
    }
    fmt.Printf("Get bucket(%s)'s location fail!\n", bucketname)
    if obsError, ok := err.(obs.ObsError); ok {
        fmt.Println("An ObsError was found, which means your request sent to OBS was rejected with an error response.")
        fmt.Println(obsError.Error())
    } else {
        fmt.Println("An Exception was found, which means the client encountered an internal problem when attempting to communicate with OBS, for example, the client was unable to access the network.")
        fmt.Println(err)
    }
}
