listInstances

参数

返回值

成功后返回一个 ListInstancesResponse 实例，可以通过这个实例的 getInstanceList() 方法，获取 List<Instance> 对象。 如果失败，抛出异常： ClientException。Instance 的属性信息参考API文档。

    static String taskName = "javaSdkTask";
    static String marker = ""; //上次listJobs返回的nextMarker，第一次查询不用填。
    static int maxItemCount = 100;  //最大100，默认50
    public static void main(String[] args) {
        BatchCompute client = new BatchComputeClient(REGION_ID, ACCESS_KEY_ID, ACCESS_KEY_SECRET);
        try{
            List<Instance> list = new ArrayList<>();
            do{
                ListInstancesResponse response = client.listInstances(jobId, taskName, marker, maxItemCount);
                //成功
                list.addAll(response.getItems());
                //下一页的marker，查询下一页的时候，需要带上这个参数
                marker = response.getNextMarker();
            }while(marker!=null && !marker.equals(""));
            for (Instance ins: list){
                System.out.println("InstanceId: " + ins.getInstanceId());
                System.out.println("InstanceState: " + ins.getState());
                System.out.println("InstanceIP: " + ins.getNodeIp());
            }
        }catch(ClientException e){
            e.printStackTrace();
            //失败
        }
    }
}

执行结果：

{
  InstanceId: 0
  InstanceState: Stopped
  InstanceIP: 10.1.98.3
}
