Querying Object Metadata

Feature description

This API is used to query object metadata.

Sample code

String bucket = "examplebucket-1250000000"; // Bucket name in the format: `BucketName-APPID`
String cosPath = "exampleobject"; // Location identifier of the object in the bucket, i.e., the object key
HeadObjectRequest headObjectRequest = new HeadObjectRequest(bucket, cosPath);
cosXmlService.headObjectAsync(headObjectRequest, new CosXmlResultListener() {
    @Override
    public void onSuccess(CosXmlRequest request, CosXmlResult result) {
        HeadObjectResult headObjectResult = (HeadObjectResult) result;
    }

    @Override
    public void onFail(CosXmlRequest cosXmlRequest,
                       CosXmlClientException clientException,
                       CosXmlServiceException serviceException) {
        if (clientException != null) {
            clientException.printStackTrace();
        } else {
            serviceException.printStackTrace();
        }
    }
});
