1:开通视频点播服务，并可以上传视频做一些设置，转码，分类等
2:根据官方提供sdk示例， 实现上传视频功能
3:代码实现
引入依赖

</dependency>这个块有个问题，使用上传SDK aliyun-java-vod-upload-1.4.13.jar时，这个包下载不下来，是由于这个包没有开源，
那么先解决这个问题，
1:先在官方文档中下载Java上传SDK及示例代码VODUploadDemo-java-1.4.13.zip
2:解压后打开lib目录，然后打开cmd窗口，执行如下命令，版本号根据自己的修改
mvn install:install-file -DgroupId=com.aliyun -DartifactId=aliyun-sdk-vod-upload -Dversion=1.4.11 -Dpackaging=jar -Dfile=aliyun-java-vod-upload-1.4.11.jar3:根据下载的aliyun-java-vod-upload-1.4.13.jar中的 UploadVideoDemo.java文件参照，里面都是上传案例，我们用流的方式上传，代码如下
controller层
@PostMapping("uploadAlyiVideo")
public R uploadAlyiVideo(MultipartFile file) {
//返回上传视频id
String videoId = vodService.uploadVideoAly(file);
return R.ok().data("videoId",videoId);
}service层
@Override
public String uploadVideoAly(MultipartFile file) {
try {
//accessKeyId, accessKeySecret
//fileName：上传文件原始名称
// 01.03.09.mp4
String fileName = file.getOriginalFilename();
//title：上传之后显示名称
String title = fileName.substring(0, fileName.lastIndexOf("."));
//inputStream：上传文件输入流
InputStream inputStream = file.getInputStream();
UploadStreamRequest request = new UploadStreamRequest(ConstantVodUtils.ACCESS_KEY_ID,ConstantVodUtils.ACCESS_KEY_SECRET, title, fileName, inputStream);
UploadVideoImpl uploader = new UploadVideoImpl();
UploadStreamResponse response = uploader.uploadStream(request);
String videoId = null;
if (response.isSuccess()) {
videoId = response.getVideoId();
} else { //如果设置回调URL无效，不影响视频上传，可以返回VideoId同时会返回错误码。其他情况上传失败时，VideoId为空，此时需要根据返回错误码分析具体错误原因
videoId = response.getVideoId();
}
return videoId;
}catch(Exception e) {
e.printStackTrace();
return null;
}
}4:删除视频案例：
controller层：
//根据视频id删除阿里云视频
@DeleteMapping("removeAlyVideo/{id}")
public R removeAlyVideo(@PathVariable String id) {
try {
//初始化对象
DefaultAcsClient client = InitVodCilent.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
//创建删除视频request对象
DeleteVideoRequest request = new DeleteVideoRequest();
//向request设置视频id
request.setVideoIds(id);
//调用初始化对象的方法实现删除
client.getAcsResponse(request);
return R.ok();
}catch(Exception e) {
e.printStackTrace();
throw new MyRuntimeException(20001,"删除视频失败");
}
}
//删除多个阿里云视频的方法
//参数多个视频id List videoIdList
@DeleteMapping("delete-batch")
public R deleteBatch(@RequestParam("videoIdList") List<String> videoIdList) {
vodService.removeMoreAlyVideo(videoIdList);
return R.ok();
}service层
@Override
public void removeMoreAlyVideo(List videoIdList) {
try {
//初始化对象
DefaultAcsClient client = InitVodCilent.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
//创建删除视频request对象
DeleteVideoRequest request = new DeleteVideoRequest();
//videoIdList值转换成 1,2,3
String videoIds = StringUtils.join(videoIdList.toArray(), ",");
//向request设置视频id
request.setVideoIds(videoIds);
//调用初始化对象的方法实现删除
client.getAcsResponse(request);
}catch(Exception e) {
e.printStackTrace();
throw new MyRuntimeException(20001,"删除视频失败");
}
}
public static void main(String[] args) {
List<String> list = new ArrayList<>();
list.add("11");
list.add("22");
list.add("33");
// 11,22,33
String join = StringUtils.join(list.toArray(), ",");
System.out.println(join);
}三：实现在浏览器播放阿里云点播视频
注意: 其中如果不是加密转码视频，就直接用视频地址播放就可以，但是如果是转码加密视频，就需要获取播放凭证后才能转码
参考文档：https://help.aliyun.com/document_detail/61109.html
一、后端获取播放凭证
//根据视频id获取视频凭证
@GetMapping("getPlayAuth/{id}")
public R getPlayAuth(@PathVariable String id) {
try {
//创建初始化对象
DefaultAcsClient client =
InitVodCilent.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
//创建获取凭证request和response对象
GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
//向request设置视频id
request.setVideoId(id);
//调用方法得到凭证
GetVideoPlayAuthResponse response = client.getAcsResponse(request);
String playAuth = response.getPlayAuth();
return R.ok().data("playAuth",playAuth);
}catch(Exception e) {
throw new MyRuntimeException(20001,"获取凭证失败");
}
}
二、前端播放器整合
<template>
<div>
<!-- 阿里云视频播放器样式 -->
<link rel="stylesheet" href="https://g.alicdn.com/de/prismplayer/2.8.1/skins/default/aliplayer-min.css" >
<!-- 阿里云视频播放器脚本 -->
<script charset="utf-8" type="text/javascript" src="https://g.alicdn.com/de/prismplayer/2.8.1/aliplayer-min.js" />
<!-- 定义播放器dom -->
<div id="J_prismPlayer" class="prism-player" />
</div>
</template>
<script>
import vod from '@/api/vod'
export default {
layout: 'video',//应用video布局
asyncData({ params, error }) {
console.log(params)
console.log(params.vid)
return vod.getPlayAuth(params.vid)
.then(response => {
return {
playAuth: response.data.data.playAuth,
vid: params.vid
}
})
},
mounted() { //页面渲染之后 created
new Aliplayer({
id: 'J_prismPlayer',
vid: this.vid, // 视频id
playauth: this.playAuth, // 播放凭证
encryptType: '1', // 如果播放加密视频，则需设置encryptType=1，非加密视频无需设置此项
width: '100%',
height: '500px',
// 以下可选设置
cover: 'http://guli.shop/photo/banner/1525939573202.jpg', // 封面
qualitySort: 'asc', // 清晰度排序
mediaType: 'video', // 返回音频还是视频
autoplay: false, // 自动播放
isLive: false, // 直播
rePlay: false, // 循环播放
preload: true,
controlBarVisibility: 'hover', // 控制条的显示方式：鼠标悬停
useH5Prism: true, // 播放器类型：html5
}, function(player) {
console.log('播放器创建成功')
})
}
}
</script>
