After you call an API in an instance of ObsClient, an instance of the HeaderResponse class (or its sub-class) will be returned. It contains information about HTTP/HTTPS response headers.
Sample code for processing public response headers:
String endPoint = "yourdomainname"; String ak = "*** Provide your Access Key ***"; String sk = "*** Provide your Secret Key ***"; // Create an instance of ObsClient. ObsClient obsClient = new ObsClient(ak, sk, endPoint); HeaderResponse response = obsClient.createBucket("bucketname"); // Obtain the UUID from the public response headers. System.out.println("\t" + response.getResponseHeaders().get("request-id")); obsClient.close();
