Spring Cloud + Vue前后端分离-第10章 基于阿里云OSS的文件上传

前面介绍的文件上传是基于本地文件服务器的文件上传，但是自己搭文件服务器会有很多运维的问题，比如磁盘满了要扩容，高峰期要增加带宽，低谷期要减少带宽，为了安全，我们还要对文件做备份等等。

所以一般会选择云平台来存储文件，云平台有很多，比如阿里云、腾讯云、百度云等，云平台做的最好的是亚马逊，我们这里选择国内最大的阿里云。

10-1 阿里云OSS简介

面向海量数据规模的分布式存储服务

从浏览器通过ECS( 服务器)访问OSS，算内网访问，不算流量费，但是要考虑ECS的带宽问题。从浏览器直接访问OSS资源，算外网访问OSS，需付流量费，但是可以不用考虑带宽。

10-2 基于OSS接口的文件上传

 记得修改自己的

VOD上传到指定分类，并自动转码

1.视频加密与授权播放：基于 OSS原生SDK上传视频到点播服务，上传到指定分类，并自动转码

VodUtil.java

视频点播不支持追加上传

1.视频加密与授权播放：基于 OSS原生SDK上传视频到点播服务，视频点播不支持追加上传

官方示例中，用的是简单上传putObject ,我们要改成我们需要的追加上传

但是有严格封装编码要求的文件类型，都是不支持追加方式上传的；比如音视频、图片等，上传到视频点播不支持追加上传

VodUtil.java

效果就不演示了，感兴趣的自己尝试一下，把这段代码打开，把上面的单文件上传注释，然后看效果，是一直在上传，但是无法上传成功！

项目集成VOD上传

小节增加vod字段

1.视频加密与授权播放：小节增加vod字段

由于视频点播不支持追加上传，我们只能改成单文件传

all.sql

generatorConfig.xml

SectionDto.java

section.vue

简单快速的方案：在阿里云控台做文件上传和转码，然后将vod复制到我们自己的控台

增加vod组件，用于上传视频到视频点播服务

1.视频加密与授权播放：增加vod组件，用于上传视频到视频点播服务

big-file.vue

vod组件就是对big-file组件做了一层封装。程序员天然喜欢对代码做封装，要注意度，封装得越多，灵活度就越低

vod.vue

<template><big-file v-bind:input-id="inputId"v-bind:text="text"v-bind:suffixs="suffixs"v-bind:use="use"v-bind:after-upload="afterUpload"v-bind:shard-size="shardSize"v-bind:url="'oss-append'"></big-file>
</template><script>
import BigFile from "./big-file";
export default {name: "vod",components: {BigFile},props: {text: {default: "上传VOD"},inputId: {default: "vod-upload"},suffixs: {default: []},use: {default: ""},shardSize: {default: 50 * 1024},afterUpload: {type: Function,default: null},},
}
</script>

目前为止，vod和big-file功能一样，需要先测试下vod组件是否可用

section.vue

 我们在js里对video赋值，vue会监听到值的变化，并渲染视频控件。如果还没渲染完，我们就去获取时长，这时就会得到NaN,所以需要加延时获取

测试，记得先清空数据库和oss文件

file表增加vod字段

1.视频加密与授权播放：file表增加vod字段

all.sql

generatorConfig.xml

FileDto.java

增加视频点播文件上传功能

1.视频加密与授权播放：增加视频点播文件上传功能

application.properties

vod.vue

由于视频点播不支持追加上传，所以使用vod组件进行上传的，只能有一个分片

section.vue

获取到的可播放地址是有时效的，所以就算保存到数据库也会过期，没用。以后会根据vod来播放。

文件检查时，根据是否是视频点播文件来获取视频信息

1.视频加密与授权播放：文件检查时，根据是否是视频点播文件来获取视频信息

UploadController.java

10-6 视频授权播放功能开发

阿里云播放器的基本使用

1.视频加密与授权播放：集成阿里云播放器，制作player播放器组件

player.vue

<template><div v-bind:id="playerId">
<!--要做成动态的，所以不在这个地方写了-->
<!--    <div class="prism-player" id="J_prismPlayer"></div>--></div>
</template>
<script>
export default {name: "player",props: {playerId: {default: "player-div"},},data: function () {return {aliPlayer: {},//播放器实例}},methods: {playUrl(url) {let _this = this;console.log("开始播放:", url);//如果已经有播放器了，则将播放器div删除if (_this.aliPlayer) {_this.aliPlayer = null;$("#J_prismPlayer").remove();}// 初始化播放器$("#" + _this.playerId).append("<div class=\"prism-player\" id=\"J_prismPlayer\"></div>");_this.aliPlayer = new Aliplayer({id: "J_prismPlayer",width: '100%',autoplay: false,source: url,cover: 'http://imooc-coursemac.oss-cn-shanghai.aliyuncs.com/头像1.jpg',}, function (player) {console.log('播放器创建好了。')});},}
}
</script>

index.html

section.vue

 video控件隐藏掉，不要删除，要通过它获取时长。也可以通过视频点播的API去获取视频时长。

测试

功能更强，可以倍速等等

获取vod授权码并授权播放

1.视频加密与授权播放：获取vod授权码并授权播放，需要在存储管理中把权限设置成公共读

默认是私有的，更改为公共读

VodUtil.java

VodController.java

player.vue

一个页面可能会放多个player组件，所以需要把id做成动态变化的，一个页面的元素，id值要是唯一的。

modal-player.vue

带有模态框的播放器组件modal-player,里面包含了player组件

<template><div id="player-modal" class="modal" tabindex="-1" role="dialog"><div class="modal-dialog" role="document"><div class="modal-content"><div class="modal-body"><player v-bind:player-id="'modal-player-div'"ref="player"></player></div></div></div></div>
</template>
<script>
import Player from "./player";
export default {name: 'modal-player',components: {Player},data: function () {return {aliPlayer: {}, // 播放器实例}},methods: {playUrl(url) {let _this = this;_this.$refs.player.playUrl(url);},playVod(vod) {let _this = this;_this.$refs.player.playVod(vod);$("#player-modal").modal("show");}}
}
</script><style scoped>
#player-modal .modal-body {padding: 0;
}
</style>

section.vue
