参考样例
在准备好开发和运行环境后,用户可根据需求开发样例。
例如使用LakeFormation Java SDK开发程序的参考代码如下:
(如下代码介绍了初始化SDK、创建LakeFormationClient实例、创建请求,添加参数、查询Catalogs列表的相关代码。)
package com.huawei.cloud.dalf.lakecat.examples; import com.huaweicloud.sdk.core.auth.BasicCredentials; import com.huaweicloud.sdk.core.exception.ClientRequestException; import com.huaweicloud.sdk.core.exception.ServerResponseException; import com.huaweicloud.sdk.core.http.HttpConfig; import com.huaweicloud.sdk.lakeformation.v1.LakeFormationClient; import com.huaweicloud.sdk.lakeformation.v1.model.ListCatalogsRequest; import com.huaweicloud.sdk.lakeformation.v1.model.ListCatalogsResponse; import java.util.ArrayList; import java.util.List; public class LakeFormationExample { public static void main(String[] args) { // getAk(),getSk()方法需自行实现,可以从配置项或其他位置获取AK/SK // 请勿在代码中硬编码AK/SK String ak = getAk(); String sk = getSk(); // projectId: 项目ID String projectId = "{******your project id******}"; // 1.初始化SDK HttpConfig config = HttpConfig.getDefaultHttpConfig(); config.withIgnoreSSLVerification(true); List<String> endpoints = new ArrayList<>(); endpoints.add("lakeformation.lakecat.com"); BasicCredentials basicCredentials = new BasicCredentials().withAk(ak).withSk(sk).withProjectId(projectId); // 2.创建LakeFormationClient实例 LakeFormationClient client = LakeFormationClient.newBuilder() .withHttpConfig(config) .withCredential(basicCredentials) .withEndpoints(endpoints) .build(); // 3.创建请求,添加参数 ListCatalogsRequest listCatalogsRequest = new ListCatalogsRequest().withInstanceId("{******your instance id******}"); // 4.查询Catalogs列表 try { ListCatalogsResponse response = client.listCatalogs(listCatalogsRequest); System.out.println(response.getHttpStatusCode()); System.out.println(response); } catch (ClientRequestException | ServerResponseException e) { System.out.println(e.getHttpStatusCode()); System.out.println(e.getMessage()); } } }
