代码示例

本文操作示例主要以代码形式体现，具体代码如下： 
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.bssopenapi.model.v20171214.*;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.profile.DefaultProfile;
import com.google.gson.Gson;

/**

 */
public class QueryAccountBalanceDemo {

    /**

     */
    private QueryAccountBalanceResponse queryAccountBalance(QueryAccountBalanceRequest request, IAcsClient client){
        try {
            // 调用SDK发送请求
            return client.getAcsResponse(request);
        } catch (ClientException e) {
            e.printStackTrace();
            // 发生调用错误，抛出运行时异常
            throw new RuntimeException();
        }
    }

    /**

        QueryAccountBalanceDemo queryAccountBalanceDemo = new QueryAccountBalanceDemo();

        // 查询账户余额
        QueryAccountBalanceRequest queryAccountBalanceRequest = new QueryAccountBalanceRequest();

}
