SDK Common Response Headers (SDK for Java)

After you successfully call an API in an instance of ObsClient, an instance of the HeaderResponse class (or of its sub-class) will be returned.

It contains information about HTTP/HTTPS response headers.

Sample code for processing public response headers:

   
        // Replace the following region with the one in use. CN-Hong Kong is used here as an example.
String endPoint = "https://obs.ap-southeast-1.myhuaweicloud.com";
// Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables. In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, configure environment variables ACCESS_KEY_ID and SECRET_ACCESS_KEY_ID.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
String ak = System.getenv("ACCESS_KEY_ID");
String sk = System.getenv("SECRET_ACCESS_KEY_ID");
// Create an ObsClient instance.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);
HeaderResponse response = obsClient.createBucket("bucketname");

// Obtain the request ID from the common response headers.
System.out.println("\t" + response.getRequestId());

obsClient.close();
