1、截图功能,查询当前频道正在直播的截图(截图五分钟更新一次)
2、接口URL中的{channelId}为频道号
3、接口支持https协议
http://api.polyv.net/live/v2/stream/{channelId}/capture
http://api.polyv.net/live/v2/stream/1965681/capture
appId=frlr1zazn3&sign=56CB347C3D71093F0D8EFBE59AF7CDA0×tamp=1621842995655
强烈建议您使用直播Java SDK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。
