媒资图像标签示例

本章节对媒资图像标签AK/SK方式使用SDK进行示例说明。

• 媒资图像标签示例代码只需将AK/SK信息替换为实际AK/SK，代码中可以使用ImageMediaTaggingReq中的withUrl或withImage方法配置图像信息（image和url参数二选一），示例中以url为例，配置完成后运行即可。
• endpoint是华为云各服务应用区域和各服务的终端节点，详情请查看 地区和终端节点 。

1. 媒资图像标签调用示例代码如下：

   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 RunImageMediaTaggingSolution {
   
       public static void main(String[] args) {
          // 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险，建议在配置文件或者环境变量中密文存放，使用时解密，确保安全
          // 本示例以ak和sk保存在环境变量中来实现身份验证为例，运行本示例前请先在本地环境中设置环境变量HUAWEICLOUD_SDK_AK和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("cn-north-4"))  //此处替换为您开通服务的区域
                   .build();
           RunImageMediaTaggingRequest request = new RunImageMediaTaggingRequest();
           ImageMediaTaggingReq body = new ImageMediaTaggingReq();
           body.withThreshold(10f);
           body.withLanguage("zh");
           body.withUrl("https://XXX.jpg");  //此处替换为公网可以访问的图片地址
           request.withBody(body);
           try {
               RunImageMediaTaggingResponse response = client.runImageMediaTagging(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. 执行示例代码文件，控制台输出媒资图像标签结果即表示程序执行成功。相关参数说明请参考媒资图像标签API。
