# 修改课节状态为禁止上课

### 接口描述

```
1、禁止课节上课，禁止有效期为24小时，24小时后会恢复课节允许上课（如果课节已到达下课时间，则不允许再上课）
2、接口URL中的{lessonId}为课节号
3、接口支持https协议
```

### 接口URL

```
http://api.polyv.net/hi-class-api/open/lesson/v1/{lessonId}/cutoff
```

### 请求方式

```
POST
```

### 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/vclass/api/limit/README.md)

### 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
private static final Logger log = LoggerFactory.getLogger(ChannelStateTest.class);
/**
 * 禁止直播频道推流
 * @throws IOException
 * @throws NoSuchAlgorithmException
 */
@Test
public void testCutoff() 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 userId = super.userId;
    String timestamp = String.valueOf(System.currentTimeMillis());
    //业务参数
    String url = "http://api.polyv.net/hi-class-api/open/lesson/v1/%s/cutoff";
    String lessonId = "11687";
    
    url = String.format(url, lessonId);
    Map<String, String> requestMap = new HashMap<>();
    requestMap.put("appId", appId);
    requestMap.put("timestamp", timestamp);
    requestMap.put("userId", userId);
    requestMap.put("sign", LiveSignUtil.getSign(requestMap, appSecret));
    String response = HttpUtil.postFormBody(url, requestMap);
    log.info("修改课节状态为禁止上课，返回值：{}", 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/vclass-copy/api/lesson/cutoff.md?ask=<question>
```

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.
