# 批量查询频道直播流信息
### 接口描述
```
1、批量获取频道直播的实时推流信息
2、deployAddress、inAddress、lfr信息可能无法获取，返回值为null
3、接口支持https协议
```
### 接口URL
```
http://api.polyv.net/live/v3/channel/monitor/get-streams
```
[在线API调用](https://git.polyv.net/help-center/document-center/-/blob/master/req.html?api=http:/api.polyv.net/live/v3/channel/monitor/get-streams/README.md)
### 请求方式
```
GET
```
### 接口约束
1、接口同时支持HTTP 、HTTPS ，建议使用HTTPS 确保接口安全，接口调用有频率限制，[详细请查看](https://git.polyv.net/help-center/document-center/-/blob/master/live/api/limit/README.md)
2、获取频道直播流信息需要频道为直播中状态
### 请求参数描述
| 参数名 | 必选 | 类型 | 说明 |
| ---------- | ---- | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| appId | true | String | 账号appId【详见[获取密钥](https://git.polyv.net/help-center/document-center/-/blob/master/live/api/getSecretKey/README.md)】 |
| timestamp | true | Long | 当前13位毫秒级时间戳，3分钟内有效 |
| sign | true | String | 签名，为32位大写的MD5值,`生成签名的appSecret密钥作为通信数据安全的关键信息，严禁保存在客户端直接使用，所有API都必须通过客户自己服务器中转调用POLYV服务器获取响应数据`【详见[签名生成规则](https://git.polyv.net/help-center/document-center/-/blob/master/live/api/buildSign/README.md)】 |
| channelIds | true | String | 直播中的频道号，多个频道用英文逗号分隔，最多100个 |
### 示例
```requestUrl
http://api.polyv.net/live/v3/channel/monitor/get-streams?appId=frlr1zazn3&sign=6DDD5D27EAE6C9EE1713F9E2AEB59D99&channelIds=4184547%2C4184544%2C4146015%2C4146008×tamp=1692322685465
```
### 响应参数描述
| 参数名 | 类型 | 说明 |
| ------- | ------- | -------------------------------------------------------------------------------------------------------------------------------- |
| code | Integer | 响应状态码，200为成功返回，非200为失败【详见[全局错误说明](https://git.polyv.net/help-center/document-center/-/blob/master/live/api/errorInfo/README.md)】 |
| status | String | 响应状态文本信息 |
| message | String | 响应描述信息，当code为400或者500的时候，辅助描述错误原因 |
| data | Array | 请求成功时为频道实时推流信息列表【详见[data字段描述](#data字段描述)】 |
### data字段描述
| 参数名 | 类型 | 说明 |
| ---------- | ------- | ------------------------------------------------------------ |
| channelId | String | 频道号 |
| live | Boolean | 频道是否直播中
true：直播中
false：未直播
|
| streamInfo | Object | 频道推流信息，直播中才有值，未直播时为null【详见[streamInfo字段描述](#streamInfo字段描述)】 |
### streamInfo字段描述
| 参数名 | 类型 | 说明 |
| ------------- | ------ | ------------ |
| deployAddress | String | 推送的CDN节点IP地址 |
| inAddress | String | 推流出口IP地址 |
| streamName | String | 流名 |
| fps | String | 推流帧率 |
| lfr | String | 推流丢帧率 |
| inBandWidth | String | 推流码率，单位：bps |
### Java请求示例
快速接入基础代码请下载相关依赖源码， [点击下载源代码](https://git.polyv.net/help-center/document-center/-/blob/master/third_res/util.zip) ,下载后加入到自己的源码工程中即可。测试用例中的**HttpUtil.java 和 LiveSignUtil.java** 都包含在下载文件中。
> 强烈建议您使用[直播Java SDK](https://git.polyv.net/help-center/document-center/-/blob/master/live/java/README.md)完成API的功能对接，直播Java SDK 对API调用逻辑、异常处理、数据签名、HTTP请求线程池进行了统一封装和优化。
```java
/**
* 批量查询频道直播流信息
* @throws IOException
* @throws NoSuchAlgorithmException
*/
@Test
public void getStreamsInfoTest() throws IOException, NoSuchAlgorithmException {
//公共参数,填写自己的实际参数
String appId = super.appId;
String appSecret = super.appSecret;
String timestamp = String.valueOf(System.currentTimeMillis());
//业务参数
String url = "http://api.polyv.net/live/v3/channel/monitor/get-streams";
String channelIds = "4184547,4184544,4146015,4146008";
//http 调用逻辑
Map requestMap = new HashMap<>();
requestMap.put("appId", appId);
requestMap.put("timestamp", timestamp);
requestMap.put("channelIds", channelIds);
requestMap.put("sign", LiveSignUtil.getSign(requestMap, appSecret));
String response = HttpUtil.get(url, requestMap);
log.info("测试批量查询频道直播流信息成功：{}", response);
//do somethings
}
```
