最近在做小程序直播，用到了腾讯云直播，下面为相关文档和程序

URL规则：https://cloud.tencent.com/document/product/267/13457

防盗链计算：https://cloud.tencent.com/document/product/267/13458

小程序源码调试(推流)：https://cloud.tencent.com/document/product/454/12554

观看直播：在下面程序生成的三个视频直播URL中任选一个，使用播放器播放

代码如下：

package com.zhaoyl.emall.bkstage.web.data;

import java.security.NoSuchAlgorithmException;
