Demo Project of Image Tagging

This section describes how to use the Image Tagging SDK by AK/SK authentication.

  • Replace the AK/SK in the sample code with the actual AK/SK. You can use the withUrl or withImage method of the ImageTaggingReq class to configure image information (either the image or url parameter). This section uses url as an example.
  • endpoint indicates the regions and endpoints for HUAWEI CLOUD services. For details, see Regions and Endpoints.
  1. The sample code for calling Image Tagging is as follows:
    package com.huaweicloud.sdk.test;
    import com.huaweicloud.sdk.core.auth.ICredential;
    import com.huaweicloud.sdk.core.auth.BasicCredentials;
    import com.huaweicloud.sdk.core.exception.ConnectionException;
    import com.huaweicloud.sdk.core.exception.RequestTimeoutException;
    import com.huaweicloud.sdk.core.exception.ServiceResponseException;
    import com.huaweicloud.sdk.image.v2.region.ImageRegion;
    import com.huaweicloud.sdk.image.v2.*;
    import com.huaweicloud.sdk.image.v2.model.*;
    public class RunImageTaggingSolution {
        public static void main(String[] args) {
        //Enter your AK/SK.
            String ak = "<YOUR AK>"; 
            String sk = "<YOUR SK>";
            ICredential auth = new BasicCredentials()
            ImageClient client = ImageClient.newBuilder()
            RunImageTaggingRequest request = new RunImageTaggingRequest();
            ImageTaggingReq body = new ImageTaggingReq();
            body.withUrl("https://XXX.jpg");  //Replace it with an image URL that can be accessed from the Internet.
            try {
                RunImageTaggingResponse response = client.runImageTagging(request);
            } catch (ConnectionException e) {
            } catch (RequestTimeoutException e) {
            } catch (ServiceResponseException e) {
  2. Execute the sample code. If 200 is displayed on the console, the code is successfully executed. For details about related parameters, see Image Tagging APIs.
