本章节以ListSearchLog为例，为您演示如何通过阿里云CLI、OpenAPI Explorer和阿里云SDK等开发者工具调用阿里云Elasticsearch
API。
背景信息
调用API时，您可以根据API文档了解使用说明，并查询必选的请求参数。发送请求后报错时，您可以在相应API文档中获取错误码说明。
阿里云CLI示例
- 获取实例ID。
- 使用ListSearchLog获取实例的系统日志。
aliyun elasticsearch ListSearchLog --type INSTANCELOG --query level:warn --beginTime 1593332477000 --endTime 1593418877000 --page 1 --size 20 --InstanceId es-cn-n6w1o1x0w00******
Java SDK示例
- 创建Maven工程。
- 配置pom依赖。
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-elasticsearch</artifactId>
<version>3.0.16</version>
</dependency>
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-core</artifactId>
<version>4.4.6</version>
</dependency>
- 创建Java程序，调用ListSearchLog查询实例的系统日志。

CommonRequest request = new CommonRequest();

request.setMethod(MethodType.GET);

String requestBody = "" +

request.setHttpContent(requestBody.getBytes(), "utf-8", FormatType.JSON);
try {
CommonResponse response = client.getCommonResponse(request);
System.out.println(response.getData());
} catch (ServerException e) {
e.printStackTrace();
} catch (ClientException e) {
e.printStackTrace();
}
}
