推流地址 java_Java实现腾讯云直播生成推流地址和播放地址
最近在做小程序直播，用到了騰訊云直播，下面為相關文檔和程序
URL規則：https://cloud.tencent.com/document/product/267/13457
防盜鏈計算：https://cloud.tencent.com/document/product/267/13458
小程序源碼調試(推流)：https://cloud.tencent.com/document/product/454/12554
觀看直播：在下面程序生成的三個視頻直播URL中任選一個，使用播放器播放
代碼如下：
package com.zhaoyl.emall.bkstage.web.data;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;

}
/**

//推流防盜鏈
String key = "9999cb04c2398c576895898031be0000";

//時間戳16進制
String txTime = Integer.toHexString(unixTime.intValue()).toUpperCase();
