## 一、概述
查询当前卡池中单卡流量；
## 二、接口
~~~[api]
post:/pool/query/flow
*string:rayOauthServerAppId=默认值#头部参数，应用的appId，联系厂商获取
*string:rayOauthServerTimeStamp=默认值#头部参数，当前时间戳，参考前述算法
*string:rayOauthServerSignature=默认值#头部参数,签名，参考前述算法
*string:userCode=默认值#卡片的用户码

## 三、关键字段
| 字段名称 || 说明 |
| --- | --- |---|
|statu||状态 200:成功|
|code||状态码 200:成功|
|message||提示消息|
|bizCode||0|
|timestamp||时间戳|
|result|cardPooledLatestData|返回结果|
|| cardId| 卡片id |
|| flowData| 卡片用量 |
|| curLogicMonth| 当前逻辑月份 |
## 四、参考代码
```
Log4jV2Util.initLog4jV2TestEnv();
String hostUrl = "http://{hosturl}";
String apiUrl = "/pool/query/flow";
String appId = "ray40c9903c6";
String appSecret = "46bacebf-f63c-41cc-b29c-5812994a5e83";
Map<String, String> paramap = new HashMap();
paramap.put("userCode", "34750");
String result = OauthCaller.call(hostUrl, apiUrl, appId, appSecret, paramap);
Logger logger = LoggerFactory.getLogger(OauthClientTest.class);
logger.warn(result);
```
