feat: support huaweicloud OBS for Oss

[showlovetommy]

I'd like to support HuaweiCloud OBS for Oss.

I want to deploy the ApiTable on HuaweiCloud and use the obs as the storage.

TodoList:

1. add the obs dependencies on backend-server\lib.gradle
   'huaweicloud-obs' : "com.huaweicloud:esdk-obs-java-bundle:${huaweicloud_obs_sdk_version}"
2. define the package version on backend-server/gradle.properties
   huaweicloud_obs_sdk_version=3.22.12
3. add HuaweiCloud class on com.apitable.starter.oss\autoconfigure\OssProperties

public class OssProperties {
    ...
    private HuaweiCloud huaweicloud;
    public HuaweiCloud getHuaweicloud() {
        return huaweicloud;
    }
    public void setHuaweicloud(HuaweiCloud huaweicloud) {
        this.huaweicloud = huaweicloud;
    }
    public static class HuaweiCloud {
        private String endpoint;
        private String accessKey;
        private String secretKey;
        public String getEndpoint() {
            return endpoint;
        }
        public void setEndpoint(String endpoint) {
            this.endpoint = endpoint;
        }
        public String getAccessKey() {
            return accessKey;
        }
        public void setAccessKey(String accessKey) {
            this.accessKey = accessKey;
        }
        public String getSecretKey() {
            return secretKey;
        }
        public void setSecretKey(String secretKey) {
            this.secretKey = secretKey;
        }
    }
   // add a new enum OssType
    public enum OssType {
    ...
        /**
         * Huawei Cloud
         */
        HUAWEICLOUD
    }
} 

4. add HuaweiCloudOssClientRequest on com.apitable.starter.oss\core\obs

  public class HuaweiCloudOssClientRequest  extends AbstractOssClientRequest{
  
      private static final Logger LOGGER = LoggerFactory.getLogger(com.apitable.starter.oss.core.obs.HuaweiCloudOssClientRequest.class);
      private final ObsClient obsClient;
      public HuaweiCloudOssClientRequest(ObsClient obsClient) {
          this.obsClient = obsClient;
      }
      public HuaweiCloudOssClientRequest(ObsClient obsClient, boolean autoCreateBucket) {
          this.obsClient = obsClient;
          this.autoCreateBucket = autoCreateBucket;
      }
      @Override
      protected boolean isBucketExist(String bucketName) {
      }
      @Override
      public boolean deleteObject(String bucketName, String key) {
      }
      @Override
      public OssObject getObject(String bucketName, String path) {
      }
      @Override
      public OssStatObject getStatObject(String bucketName, String key) {
      }
      @Override
      public void executeStreamFunction(String bucketName, String key, Consumer<InputStream> function) {
      }
      @Override
      public void refreshCdn(String bucketName, String[] url) {
      }
      @Override
      public UrlFetchResponse uploadRemoteUrl(String bucketName, String remoteSrcUrl, String keyPath) throws IOException {
      }
      @Override
      public void uploadStreamForObject(String bucketName, InputStream in, String keyPath) throws IOException {
      }
      @Override
      public void uploadStreamForObject(String bucketName, InputStream in, String path, String mimeType, String digest)
      }
  }

5. add HuaweiCloudOssClientRequestFactory class on com.apitable.starter.oss\core\obs

public class HuaweiCloudOssClientRequestFactory implements OssClientRequestFactory {
    private final String ak;
    private final String sk;
    private final String endpoint;
    public HuaweiCloudOssClientRequestFactory(String ak, String sk, String endpoint) {
        this.ak = ak;
        this.sk = sk;
        this.endpoint = endpoint;
    }
    @Override
    public OssClientRequest createClient() {
        ObsClient obsClient = new ObsClient(ak, sk, endpoint);
        return new HuaweiCloudOssClientRequest(obsClient, true);
    }
}

6. add HuaweiCloudOBSAutoConfiguration class on com.apitable.starter.oss\autoconfigure

@Configuration(proxyBeanMethods = false)
@ConditionalOnClass(ObsClient.class)
@ConditionalOnProperty(value = "starter.oss.type", havingValue = "huawei-cloud")
public class HuaweiCloudOBSAutoConfiguration extends  OssConnectionConfiguration{
    public HuaweiCloudOBSAutoConfiguration(OssProperties properties) {
        super(properties);
    }
    @Bean
    @ConditionalOnMissingBean(OssClientRequestFactory.class)
    OssClientRequestFactory ossClientRequestFactory() {
      HuaweiCloud huaweicloud = getProperties().getHuaweicloud();
      return new HuaweiCloudOssClientRequestFactory( huaweicloud.getAccessKey(), huaweicloud.getSecretKey(), huaweicloud.getEndpoint());
    }
}

7. add HuaweiCloudOBSAutoConfiguration.class on com.apitable.starter.oss\autoconfigure\OssAutoConfiguration @import

@Import({ AwsS3AutoConfiguration.class,
        QiniuCloudAutoConfiguration.class,
        HuaweiCloudOBSAutoConfiguration.class,
        MinioAutoConfiguration.class })
public class OssAutoConfiguration {
...
}

8. add config on backend-server\application\src\main\resources\application.yml

starter:
  oss:
    huawei-cloud:
      access-key: ${HUAWEICLOUD_ACCESS_KEY:}
      secret-key: ${HUAWEICLOUD_SECRET_KEY:}
      endpoint: ${HUAWEICLOUD_ENDPOINT:obs.cn-south-1.myhuaweicloud.com}

9. add ENVIRONMENT_VAR on .env

HUAWEICLOUD_ACCESS_KEY= YOUR AK
HUAWEICLOUD_SECRET_KEY= YOUR SK
HUAWEICLOUD_ENDPOINT= YOUR ENDPOINT
