Java SDK user guide

Prerequisites

Install JDK 1.6 or a later version.

Get the Java SDK

You can obtain the Java SDK directly from Maven. This is the recommended method for online environments.

<dependency>
  <groupId>com.aliyun</groupId>
  <artifactId>aliyun-java-sdk-core</artifactId>
<version>4.5.6</version>
</dependency>
<dependency>
  <groupId>com.aliyun</groupId>
  <artifactId>aliyun-java-sdk-ahas-openapi</artifactId>
  <version>1.0.4</version>
</dependency>

Use the Java SDK to call an API

Replace aliyun_user_ak, aliyun_user_sk, and region_id in the following example with your actual parameter values.

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.ahas_openapi.model.v20190901.ListFlowRulesOfAppRequest;
import com.aliyuncs.ahas_openapi.model.v20190901.ListFlowRulesOfAppResponse;
import com.aliyuncs.profile.DefaultProfile;


public class ListFlowRuleDemo {
    public static void main(String[] args){
        String regionId = "cn-hangzhou"; // The ID of the region where the application that calls the API resides.
        String accessKey = "**************"; // The AccessKey ID of your Alibaba Cloud account or RAM user.
        String accessSecret = "**************"; // The AccessKey secret of your Alibaba Cloud account or RAM user.
        String appName = "ahas-demo"; // The name of the application to query.
        String namespace = "default"; // The namespace where the application resides.

        DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKey, accessSecret);
        IAcsClient client = new DefaultAcsClient(profile);
        ListFlowRulesOfAppRequest request = new ListFlowRulesOfAppRequest();
        // To call the OpenAPI over the internet, set ahasRegionId to public. Do not set this parameter for other regions.
        request.setAhasRegionId("public");
        request.setAppName(appName);
        request.setNamespace(namespace);
        try{
            // Send the request.
            ListFlowRulesOfAppResponse response = client.getAcsResponse(request);
            // Get and process the response.
            System.out.println(response.getData());
        }catch(Exception e){
            e.printStackTrace();
        }
    }
}
