CRMEB知识付费二次开发 加密阿里云视频MP4点播链接为m3u8格式 hls blob协议
只有添加分发加速的域名才能使用HLS加密,同时也要做HTTPS证书添加,不然也会报错。 1、这是电脑端视频播放页面效果 2、这个手机端H5视频播放页面效果 3、在网站后台上传你的视频内容 4、上传完之后可以进行预览 5、在阿里云控制台设置就好自己的转码模板 将不转码设为默认的原因是自动触发转码不支持HLS标准加密,所以需要先上传不转码,然后根据回调再去调用转码接口,实现手动转码 6、设置上传完成回调 - 用于手动转码 7、创建回调接口 可以用frp搭一个,然后就是正常的restful接口 回调是POST请求,然后请求体我是用 @RequestBody String body接收的,不知道为什么,用对象接收就是不行 请求转码需要用到KMS加密,因此需要准备文档中准备工作的第三步搭建密钥管理服务生成AES_128密钥 技术开发QQ 735660248 IAcsClient client = getClient(); CommonRequest request = new CommonRequest(); request.setSysMethod(MethodType.POST);...
【大数据技术】Spark+Flume+Kafka实现商品实时交易数据统计分析实战(附源码)_spark实时大数据分析_showswoller的博客-CSDN博客
1)Kafka 是一个非常通用的系统,你可以有许多生产者和消费者共享多个主题Topics。相比之下,Flume是一个专用工具被设计为旨在往HDFS,HBase等发送数据。它对HDFS有特殊的优化,并且集成了Hadoop的安全特性。如果数据被多个系统消费的话,使用kafka;如果数据有多个生产者场景,或者有写入Hbase、HDFS操作,使用Flume。 2)Flume可以使用拦截器实时处理数据。而Kafka需要外部的流处理系统才能做到。 3)Kafka和Flume都是可靠的系统,通过适当的配置能保证零数据丢失。然而,Flume不支持副本事件。如果Flume代理的一个节点奔溃了,即使使用了可靠的文件管道方式,你也将丢失这些事件直到你恢复这些磁盘。如果你需要一个高可靠行的管道,那么使用Kafka是个更好的选择。 此开发示例的功能是商品实时交易数据统计分析,通过Flume实时收集交易订单,将数据分发Kafka,Kafka将数据传输到Spark Streaming,Spark Streaming统计商品的销售量。实现主要有以下几个步骤: 1)通过LOG日志模拟产生实时交易数据...
