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());
}
}
}
