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) {
          // Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK and store them in the configuration file or environment variables.
          // In this example, the AK and SK are stored in environment variables for identity authentication. Before running this example, configure environment variables HUAWEICLOUD_SDK_AK and HUAWEICLOUD_SDK_SK.
           String ak = System.getenv("HUAWEICLOUD_SDK_AK");
           String sk = System.getenv("HUAWEICLOUD_SDK_SK");
           ICredential auth = new BasicCredentials()
                   .withAk(ak)
                   .withSk(sk);
           ImageClient client = ImageClient.newBuilder()
                   .withCredential(auth)
                   .withRegion(ImageRegion.valueOf("XXXX"))   //Replace XXXX with the region where you enable the service. For details, see Regions and Endpoints.
                   .build();
           RunImageTaggingRequest request = new RunImageTaggingRequest();
           ImageTaggingReq body = new ImageTaggingReq();
           body.withLimit(50);
           body.withThreshold(95f);
           body.withLanguage("zh");
           body.withUrl("https://XXX.jpg");  //Replace it with an image URL that can be accessed from the Internet.
           request.withBody(body);
           try {
               RunImageTaggingResponse response = client.runImageTagging(request);
               System.out.println(response.toString());
           } catch (ConnectionException e) {
               e.printStackTrace();
           } catch (RequestTimeoutException e) {
               e.printStackTrace();
           } catch (ServiceResponseException e) {
               e.printStackTrace();
               System.out.println(e.getHttpStatusCode());
               System.out.println(e.getErrorCode());
               System.out.println(e.getErrorMsg());
           }
       }
   }

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.

   class RunImageTaggingResponse {
       result: class ImageTaggingResponseResult {
           tags: [class ImageTaggingItemBody {
               confidence: 98.00
               type: Tree
               tag: Tree
               i18nTag: class ImageTaggingItemBodyI18nTag {
                   zh: Chinese characters for tree
                   en: Tree
               }
               i18nType: class ImageTaggingItemBodyI18nType {

           }]
       }
