Alibaba Cloud SDK:Configurer un proxy

Cette rubrique explique comment configurer un proxy dans Alibaba Cloud SDK V2.0 pour Java.

Méthode de configuration

• L'exemple de code ci-dessous illustre la configuration d'un proxy au moyen de l'objet RuntimeOptions.

  import com.aliyun.ecs20140526.Client;
  import com.aliyun.ecs20140526.models.DescribeRegionsRequest;
  import com.aliyun.teaopenapi.models.Config;
  import com.aliyun.teautil.models.RuntimeOptions;
  
  public class Sample {
      public static void main(String[] args) throws Exception {
          Config config = new Config();
          // Obtain the AccessKey ID of the Resource Access Management (RAM) user from an environment variable.
          config.setAccessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"));
          // Obtain the AccessKey secret of the RAM user from an environment variable.
          config.setAccessKeySecret(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"));
          // Specify the region ID.
          config.setRegionId("<regionId>");
          Client client = new Client(config);
  
          // Create a RuntimeOptions instance and specify runtime parameters. The settings take effect only on the requests that use the RuntimeOptions instance.
          RuntimeOptions runtimeOptions = new RuntimeOptions();
          runtimeOptions.httpProxy = "http://127.0.0.1:9898";
          runtimeOptions.httpsProxy = "http://user:password@127.0.0.1:8989";
          runtimeOptions.noProxy = "127.0.0.1,localhost";
  
          DescribeRegionsRequest describeRegionsRequest = new DescribeRegionsRequest();
  
          client.describeRegionsWithOptions(describeRegionsRequest, runtimeOptions);
      }
  }

• Le code suivant montre comment configurer un proxy à l'aide de l'objet Config lors de l'initialisation du client SDK.

  import com.aliyun.ecs20140526.Client;
  import com.aliyun.ecs20140526.models.DescribeRegionsRequest;
  import com.aliyun.teaopenapi.models.Config;
  import com.aliyun.teautil.models.RuntimeOptions;
  
  public class Sample {
      public static void main(String[] args) throws Exception {
          Config config = new Config();
          // Obtain the AccessKey ID of the RAM user from an environment variable.
          config.setAccessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"));
          // Obtain the AccessKey secret of the RAM user from an environment variable.
          config.setAccessKeySecret(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"));
          // Specify the region ID.
          config.setRegionId("<regionId>");
          // Configure a proxy when you initialize the client.
          config.setHttpProxy("http://127.0.0.1:9898");
          config.setHttpsProxy("http://user:password@127.0.0.1:8989");
          config.setNoProxy("127.0.0.1,localhost");
          Client client = new Client(config);
  
          RuntimeOptions runtimeOptions = new RuntimeOptions();
          DescribeRegionsRequest describeRegionsRequest = new DescribeRegionsRequest();
  
          client.describeRegionsWithOptions(describeRegionsRequest, runtimeOptions);
      }
  }
