桶(Bucket)是 TOS 的全局唯一的命名空间,相当于数据的容器,用来储存对象(Object)数据。本文介绍如何通过 TOS Java SDK 的 getBucketLocation 接口获取桶所在的地域(Region)信息。

注意事项

只有桶的所有者(Owner)才能查看桶所在的地域(Region)。

示例代码

如下代码展示如何获取桶的地域(Region)信息。

import com.volcengine.tos.TOSV2;
import com.volcengine.tos.TOSV2ClientBuilder;
import com.volcengine.tos.TosClientException;
import com.volcengine.tos.TosServerException;
import com.volcengine.tos.model.bucket.GetBucketLocationInput;
import com.volcengine.tos.model.bucket.GetBucketLocationOutput;

public class GetBucketLocationExample {
    public static void main(String[] args) {
        String endpoint = "your endpoint";
        String region = "your region";
        String accessKey = System.getenv("TOS_ACCESS_KEY");
        String secretKey = System.getenv("TOS_SECRET_KEY");
        String bucketName = "your bucket name";

        TOSV2 tos = new TOSV2ClientBuilder().build(region, endpoint, accessKey, secretKey);

        try{
            GetBucketLocationInput input = new GetBucketLocationInput().setBucket(bucketName);
            GetBucketLocationOutput output = tos.getBucketLocation(input);
            System.out.println("bucket's region is " + output.getRegion());
            System.out.println("bucket's extranet endpoint is " + output.getExtranetEndpoint());
            System.out.println("bucket's intranet endpoint is " + output.getIntranetEndpoint());
        } catch (TosClientException e) {
            // 操作失败,捕获客户端异常,一般情况是请求参数错误,此时请求并未发送
            System.out.println("getBucketLocation failed");
            System.out.println("Message: " + e.getMessage());
            if (e.getCause() != null) {
                e.getCause().printStackTrace();
            }
        } catch (TosServerException e) {
            // 操作失败,捕获服务端异常,可以获取到从服务端返回的详细错误信息
            System.out.println("getBucketLocation failed");
            System.out.println("StatusCode: " + e.getStatusCode());
            System.out.println("Code: " + e.getCode());
            System.out.println("Message: " + e.getMessage());
            System.out.println("RequestID: " + e.getRequestID());
        } catch (Throwable t) {
            // 作为兜底捕获其他异常,一般不会执行到这里
            System.out.println("getBucketLocation failed");
            System.out.println("unexpected exception, message: " + t.getMessage());
        }
    }
}
