当您将文件上传至 TOS 后，您可以使用 TOS 自动生成的文件 URL 访问或下载文件。如果您希望使用您自己的域名访问存储在 TOS 的文件，您可以为存储桶绑定您自己的域名。绑定后，即可使用相应域名访问文件。

设置自定义域名规则 #

您可以通过 TOS Java SDK 的 putBucketCustomDomain 接口获取指定桶的自定义域名配置。

示例代码 #

以下代码展示如何设置桶的自定义域名。

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.CustomDomainRule;
import com.volcengine.tos.model.bucket.PutBucketCustomDomainInput;
import com.volcengine.tos.model.bucket.PutBucketCustomDomainOutput;

public class PutBucketCustomDomainExample {
    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 = "bucket-example";
        String customDomain = "example.test.com";

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

        try{
            CustomDomainRule rule = new CustomDomainRule().setDomain(customDomain);
            PutBucketCustomDomainInput input = new PutBucketCustomDomainInput().setBucket(bucketName).setRule(rule);
            PutBucketCustomDomainOutput output = tos.putBucketCustomDomain(input);
            System.out.println("putBucketCustomDomain succeed");
        } 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("putBucketCustomDomain 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("putBucketCustomDomain 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("putBucketCustomDomain failed");
            System.out.println("unexpected exception, message: " + t.getMessage());
        }
    }
}

列举自定义域名规则 #

您可以通过 TOS Java SDK 的 listBucketCustomDomain 接口获取指定桶配置的自定义域名列表。

示例代码 #

以下代码展示如何列举桶的自定义域名列表。

        String bucketName = "bucket-example";

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

        try{
            ListBucketCustomDomainInput input = new ListBucketCustomDomainInput().setBucket(bucketName);
            ListBucketCustomDomainOutput output = tos.listBucketCustomDomain(input);
            System.out.println("listBucketCustomDomain succeed");
            if (output.getRule() != null && output.getRule().size() > 0) {
                for(int i = 0; i < output.getRule().size(); i++) {

        } 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("listBucketCustomDomain failed");

            System.out.println("Code: " + e.getCode());
            System.out.println("Message: " + e.getMessage());
            System.out.println("RequestID: " + e.getRequestID());
        } catch (Throwable t) {
