# 查询打点信息
### 接口描述
```
1、通过视频id获取单个视频的全部打点信息
2、接口URL中的{userid}为点播账号userid，具体参考菜单【使用须知】->【获取密钥】
3、接口URL中的{vid}为视频id
4、接口支持https协议
```
### 接口URL
```
http://api.polyv.net/v2/video/{userid}/keyframe/{vid}
```
[在线API调用](https://git.polyv.net/help-center/document-center/-/blob/master/req.html?api=http:/api.polyv.net/v2/video/%7Buserid%7D/keyframe/%7Bvid%7D/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/vod/api/limit/README.md)
### 请求参数描述
| 参数名 | 必选 | 类型 | 说明 |
| ------ | ---- | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| userid | true | String | 保利威点播账户id，可以参考【[获取密钥](https://git.polyv.net/help-center/document-center/-/blob/master/vod/api/getSecretKey/README.md)】获取，获取路径：官网->登录->点播（API接口） |
| ptime | true | Long | 当前时间的毫秒级时间戳，3分钟内有效 |
| sign | true | String | 签名，为40位大写的SHA1值,`生成签名的secretkey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/vod/api/buildSign/README.md)】 |
| vid | true | String | 视频id |
### 示例
```requestUrl
http://api.polyv.net/v2/video/1b448be323/keyframe/1b448be323b8d9b9489dcd7e8e09f087_1?vid=1b448be323b8d9b9489dcd7e8e09f087_1&sign=9FD6BA6486D1655C1D1A27C436F835C43BEB8406&userid=1b448be323&ptime=1617174767293

### 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 VodSignUtil.java** 都包含在下载文件中。
> 强烈建议您使用[点播Java SDK](https://git.polyv.net/help-center/document-center/-/blob/master/vod/java/README.md)完成API的功能对接，点播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
private static final Logger log = LoggerFactory.getLogger(VodChapterMakerTest.class);
/**
*查询打点信息
* @throws Exception
* @throws NoSuchAlgorithmException
*/
@Test
public void testGetChapterMaker() throws Exception, NoSuchAlgorithmException {
//公共参数,填写自己的实际参数
String secretKey = super.secretKey;
String userId = super.userId;
String ptime = String.valueOf(System.currentTimeMillis());
//业务参数
String vid = "1b448be323b8d9b9489dcd7e8e09f087_1";
String url = String.format("http://api.polyv.net/v2/video/%s/keyframe/%s",userId,vid);
Map requestMap = new HashMap<>();
requestMap.put("userid", userId);
requestMap.put("ptime", ptime);
requestMap.put("vid", vid);
requestMap.put("sign", VodSignUtil.getSign(requestMap, secretKey));
String response = HttpUtil.get(url, requestMap);
log.debug("测试查询打点信息,{}", response);
//do somethings
}
```

# Agent Instructions: Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter:
```
GET https://polyv.gitbook.io/document/docs/vod/api/video-management/chapter-marker/get_chapter_marker.md?ask=
```
The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
