更新数据示例

本章节对更新数据AK/SK方式使用SDK进行示例说明。

更新数据示例代码只需将AK/SK信息替换为实际AK/SK,代码中可以使用UpdateParam类的withItemId、withDesc、withCustomNumTags、withCustomTags配置服务输入参数,配置完成后运行即可。

  1. 更新数据调用示例代码如下:
    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.core.region.Region;
    import com.huaweicloud.sdk.imagesearch.v2.*;
    import com.huaweicloud.sdk.imagesearch.v2.model.*;
     
    import java.util.Map;
    import java.util.HashMap;
     
    /**
     * 更新数据

    public class RunUpdateDataSolution {
     
        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");
            String iamEndpoint = "https://iam.cn-north-4.myhuaweicloud.com";
            String endpoint = "https://mms.cn-north-4.myhuaweicloud.com";
            String projectId = "project_id";
            
           // 初始化客户端
            ICredential auth = new BasicCredentials()
                    .withIamEndpoint(iamEndpoint)
                    .withProjectId(projectId)
                    .withAk(ak)
                    .withSk(sk);
     
            ImageSearchClient client = ImageSearchClient.newBuilder()
                    .withCredential(auth)
                    // 设置region, 示例中为北京四
                    .withRegion(new Region("cn-north-4", endpoint))
                    .build();
            RunUpdateDataRequest request = new RunUpdateDataRequest();
            request.withServiceName("service_name");
            UpdateParam body = new UpdateParam();
            Map<String, Double> listbodyCustomNumTags = new HashMap<>();
            listbodyCustomNumTags.put("key", (double)1);
            Map<String, String> listbodyCustomTags = new HashMap<>();
            listbodyCustomTags.put("key", "value");
            body.withCustomNumTags(listbodyCustomNumTags);
            body.withCustomTags(listbodyCustomTags);
            body.withDesc("description");
            body.withItemId("item_id");
            request.withBody(body);
            try {
                RunUpdateDataResponse response = client.runUpdateData(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.getRequestId());
                System.out.println(e.getErrorCode());
                System.out.println(e.getErrorMsg());
            }
        }
    }
  2. 执行示例代码文件,控制台输出更新数据结果即表示程序执行成功。
    class RunUpdateDataResponse {
        result: success
    }
