# 搜索数据示例
本章节对搜索数据AK/SK方式使用SDK进行示例说明。
搜索示例代码只需将AK/SK信息替换为实际AK/SK，代码中可以使用SearchParam类配置服务输入参数，其中使用SearchOptionalParam类配置服务的可选参数，配置完成后运行即可。
1. 搜索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.List;
   import java.util.ArrayList;
   import java.util.Map;
   import java.util.HashMap;
   /**
    * 搜索

   public class RunSearchSolution {
       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();
           RunSearchRequest request = new RunSearchRequest();
           request.withServiceName("service_name");
           SearchParam body = new SearchParam();
           SearchOptionalParam optionalParamsbody = new SearchOptionalParam();
           optionalParamsbody.withDoDet(true)
               .withBox("135,489,1117,1341")
               .withDoCls(true);
           List<String> listCustomTagsCustomTags = new ArrayList<>();
           listCustomTagsCustomTags.add("value1");
           listCustomTagsCustomTags.add("value2");
           listCustomTagsCustomTags.add("value3");
           Map<String, List<String>> listbodyCustomTags = new HashMap<>();
           listbodyCustomTags.put("key", listCustomTagsCustomTags);
           body.withOptionalParams(optionalParamsbody);
           // 替换为公网可以访问的图片地址
           body.withImageUrl("https://bucketname.obs.cn-north-4.myhuaweicloud.com/image/test1.jpg
   ");
           body.withCustomTags(listbodyCustomTags);
           body.withOffset(0);
           body.withLimit(30);
           body.withSearchType(SearchParam.SearchTypeEnum.fromValue("CATEGORY"));
           request.withBody(body);
           try {
               RunSearchResponse response = client.runSearch(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，控制台输出搜索数据结果即表示程序执行成功。
   ```
   class RunSearchResponse {
       result: success
       data: class SearchRestInfo {
           items: [class SearchItem {
               id: item_id
               score: 1.0
               source: null
           }]
           searchInfo: class SearchInfo {
               totalNum: 1
               returnNum: 1
               searchTime: 969
               lastItem: null
           }
           imageInfo: class SearchRestInfoImageInfo {
               box: 135,489,1117,1341
               category: 0
               categoryName: others
               objects: [class AddDataRestInfoImageInfoObjects {
                   box: 135,489,1117,1341
                   category: 0
                   categoryName: others
               }]
           }
       }
   }
   ```
