Deleting an Image

This section describes how to delete an image using AK/SK authentication.

Replace the AK/SK in the sample code with the actual AK/SK. Use the setPath method of the DeletePictureReq class to specify the URL of the image you want to delete. After the configuration is complete, run the code.

1. The sample code for deleting an image is as follows:

   import com.alibaba.fastjson.JSON;
    
   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.imagesearch.v1.*;
   import com.huaweicloud.sdk.imagesearch.v1.model.*;
   import com.huaweicloud.sdk.imagesearch.v1.region.ImageSearchRegion;
    
   /**
    * Delete an image from the index library by specifying the image path.
    */
   public class RunDeletePictureSolution {
       
       public static void main(String[] args) {
           //Set the obtained AK and SK.
           String ak = "<YOUR AK>";
           String sk = "<YOUR SK>";
           
           ICredential auth = new BasicCredentials()
               .withAk(ak)
               .withSk(sk);
           
           ImageSearchClient client = ImageSearchClient.newBuilder()
               .withCredential(auth)
               //Set the region. In this example, CN North-Beijing4 is used.
               .withRegion(ImageSearchRegion.valueOf("cn-north-4"))
               .build();
           RunDeletePictureRequest request = new RunDeletePictureRequest();
           //Set the instance name.
           request.setInstanceName("instance-name");
           DeletePictureReq body= new DeletePictureReq();
           //Image URL, which is used as the ID of an image in the image library.
                   body.setPath("https://bucketname.obs.cn-north-4.myhuaweicloud.com/search-test.jpg");
           request.setBody(body);
           try {
               RunDeletePictureResponse response = client.runDeletePicture(request);
               System.out.println(JSON.toJSONString(response));
           } 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 the image deletion result is displayed on the console, the code is successfully executed. For details, see Deleting an Image.
