SpringBoot整合阿里云视频点播的过程详解

1.准备工作

首先需要在阿里云开通视频点播服务:

1.首先,进入到阿里云视频点播平台,点击开通服务,选择按使用流量计费即可

2.开通之后点击进入管理控制台即可

视频点播有什么用?

视频点播(ApsaraVideo for VoD)是集音视频采集、编辑、上传、自动化转码处理、媒体资源管理、分发加速于一体的一站式音视频点播解决方案。

2.服务端SDK的使用

官方文档链接:Java SDK

SDK的方式将api进行了进一步的封装,不用自己创建工具类。 我们可以基于服务端SDK编写代码来调用点播API,实现对点播产品和服务的快速操作。

2.1 导入依赖

注意:环境必须是JDK6 及以上版本

<dependency>

<groupId>com.aliyun</groupId>

<artifactId>aliyun-java-sdk-core</artifactId>

<version>4.5.1</version>

</dependency>

<dependency>

<groupId>com.aliyun</groupId>

<artifactId>aliyun-java-sdk-vod</artifactId>

<version>2.15.11</version>

</dependency>

<dependency>

<groupId>com.alibaba</groupId>

<artifactId>fastjson</artifactId>

<version>1.2.62</version>

</dependency>

<dependency>

<groupId>com.aliyun</groupId>

<artifactId>aliyun-java-sdk-kms</artifactId>

<version>2.10.1</version>

</dependency>

2.2 初始化类

根据官方文档示例创建初始化类InitObject

/**

* @author xppll

* @date 2021/12/5 13:57

*/

public class InitObject {

//初始化:需要传入accessKeyId+accessKeySecret

public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) throws ClientException {

String regionId = "cn-shanghai"; //点播服务接入区域

DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKeyId, accessKeySecret);

DefaultAcsClient client = new DefaultAcsClient(profile);

return client;

}

}

accessKeyIdaccessKeySecret的获取:

这里的初始化方法需要传入账号Access Key信息,可以在阿里云Access Key管理创建主账号Access Key

点播服务接入区域regionId的获取:

点击点播控制台的存储管理,查看自己所选的区域:

在查看接入区域标识对应API/SDK的RegionId参数:

2.3 创建读取公共常量的工具类

首先在配置文件application.properties添加:

aliyun.vod.file.keyid=LTAI5tGqf41adadaxxAa

aliyun.vod.file.keysecret=zE4nEzmcU7GxxxxmTgWRk0tytJKD

# 最大上传单个文件大小:默认1M

spring.servlet.multipart.max-file-size=1024MB

# 最大置总上传的数据大小 :默认10M

spring.servlet.multipart.max-request-size=1024MB

在创建读取公共常量的工具类ConstantVodUtils

/**

* @author xppll

* @date 2021/12/2 19:11

*/

@Component

public class ConstantVodUtils implements InitializingBean {

@Value("${aliyun.vod.file.keyid}")

private String keyId;

@Value("${aliyun.vod.file.keysecret}")

private String keySecret;

//定义公共静态常量

public static String ACCESS_KEY_ID;

public static String ACCESS_KEY_SECRET;

@Override

public void afterPropertiesSet() throws Exception {

ACCESS_KEY_ID = keyId;

ACCESS_KEY_SECRET = keySecret;

}

}

2.4 获取视频播放地址

首先手动先在点播控制台上传一个视频用于测试:

步骤:

  1. 创建初始化对象
  2. 创建获取视频地址requestresponse
  3. request对象里面设置视频id
  4. 用初始化对象里面的方法getAcsResponse,传递request,获取数据
  5. 打印信息

代码如下:

//获取视频播放地址

private static void getPlayUrl() throws ClientException {

//1.创建初始化对象

DefaultAcsClient client = InitObject.initVodClient(ConstantVodUtils.ACCESS_KEY_ID,ConstantVodUtils.ACCESS_KEY_SECRET);

//2.创建获取视频地址request和response

GetPlayInfoRequest request = new GetPlayInfoRequest();

GetPlayInfoResponse response = new GetPlayInfoResponse();

//3.向request对象里面设置视频id

request.setVideoId("ffe90bfaxxx94d0d722caad");

//4.调用初始化对象里面的方法,传递request,获取数据

response = client.getAcsResponse(request);

List<GetPlayInfoResponse.PlayInfo> playInfoList = response.getPlayInfoList();

//播放地址

for (GetPlayInfoResponse.PlayInfo playInfo : playInfoList) {

System.out.print("PlayInfo.PlayURL = " + playInfo.getPlayURL() + "\n");

}

//Base信息

System.out.print("VideoBase.Title = " + response.getVideoBase().getTitle() + "\n");

}

测试成功:

2.5 获取视频播放凭证

步骤与获取视频播放地址差不多,区别是获取requestresponse方式不同:

//获取视频播放凭证

private static void getPlayAuth() throws ClientException {

//1.创建初始化对象

DefaultAcsClient client = InitObject.initVodClient(ConstantVodUtils.ACCESS_KEY_ID,ConstantVodUtils.ACCESS_KEY_SECRET);

//2.创建获取视频凭证的request和response

GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();

GetVideoPlayAuthResponse response = new GetVideoPlayAuthResponse();

//3.向request设置视频id

request.setVideoId("ffe90bfaaadd4xxxx0d722caad");

//4.调用初始化对象的方法得到凭证

response = client.getAcsResponse(request);

//播放凭证

System.out.println("playauth" + response.getPlayAuth());

}

测试成功:

2.6 上传视频到阿里云视频点播服务

可以参考:Java上传SDK

需要导入依赖:

<dependency>

<groupId>com.aliyun</groupId>

<artifactId>aliyun-java-sdk-core</artifactId>

<version>4.5.1</version>

</dependency>

<dependency>

<groupId>com.aliyun.oss</groupId>

<artifactId>aliyun-sdk-oss</artifactId>

<version>3.10.2</version>

</dependency>

<dependency>

<groupId>com.aliyun</groupId>

<artifactId>aliyun-java-sdk-vod</artifactId>

<version>2.15.11</version>

</dependency>

<dependency>

<groupId>com.alibaba</groupId>

<artifactId>fastjson</artifactId>

<version>1.2.28</version>

</dependency>

<dependency>

<groupId>org.json</groupId>

<artifactId>json</artifactId>

<version>20170516</version>

</dependency>

<dependency>

<groupId>com.google.code.gson</groupId>

<artifactId>gson</artifactId>

<version>2.8.2</version>

</dependency>

代码如下:

//上传视频到阿里云视频点播服务

private static void uploadVideo() {

String accessKeyId = ConstantVodUtils.ACCESS_KEY_ID;

String accessKeySecret = ConstantVodUtils.ACCESS_KEY_SECRET;

//上传后视频的标题

String title = "xpp1";

//本地文件上传路径

String fileName = "D:/6 - What If I Want to Move Faster.mp4";

UploadVideoRequest request = new UploadVideoRequest(accessKeyId, accessKeySecret, title, fileName);

//可指定分片上传时每个分片的大小,默认为2M字节

request.setPartSize(2 * 1024 * 1024L);

//可指定分片上传时的并发线程数,默认为1

request.setTaskNum(1);

UploadVideoImpl uploader = new UploadVideoImpl();

UploadVideoResponse response = uploader.uploadVideo(request);

if (response.isSuccess()) {

System.out.print("VideoId=" + response.getVideoId() + "\n");

} 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 */

System.out.print("VideoId=" + response.getVideoId() + "\n");

System.out.print("ErrorCode=" + response.getCode() + "\n");

System.out.print("ErrorMessage=" + response.getMessage() + "\n");

}

}

测试成功:

3.springboot项目中实践

创建初始化类:

/**

* @author xppll

* @date 2021/12/5 13:57

*/

public class InitVodCilent {

//初始化:需要传入accessKeyId+accessKeySecret

public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) throws ClientException {

String regionId = "cn-shanghai"; // 点播服务接入区域

DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKeyId, accessKeySecret);

DefaultAcsClient client = new DefaultAcsClient(profile);

return client;

}

}

3.1 上传视频到阿里云

controller层:

@Autowired

private VodService vodService;

//上传视频到阿里云

@PostMapping("uploadAlyiVideo")

public R uploadAlyVideo(MultipartFile file){

//返回上传视频id

String videoId=vodService.uploadVideoAly(file);

//将视频`id`返回给前端

return R.ok().data("videoId",videoId);

}

service层:

//上传视频到阿里云

@Override

public String uploadVideoAly(MultipartFile file) {

try {

//fileName:上传文件原始名称

String fileName = file.getOriginalFilename();

//title:上传之后显示名称(例子:01.mp4=>01)

String title = fileName.substring(0, fileName.lastIndexOf("."));

//inputStream:上传文件输入流

InputStream inputStream = file.getInputStream();

//获得request

UploadStreamRequest request = new UploadStreamRequest(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET, title, fileName, inputStream);

UploadVideoImpl uploader = new UploadVideoImpl();

//上传获得response

UploadStreamResponse response = uploader.uploadStream(request);

String videoId = null;

if (response.isSuccess()) {

//得到视频id

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 (IOException e) {

e.printStackTrace();

return null;

}

}

3.2 根据视频id删除视频

controller层:

//根据视频id删除视频

@DeleteMapping("removeAlyVideo/{id}")

public R removeAlyVideo(@PathVariable String id){

vodService.deleteAlyVideo(id);

return R.ok();

}

service层:

//根据视频id删除视频

@Override

public void deleteAlyVideo(String id) {

try {

//1.初始化对象

DefaultAcsClient client = InitVodCilent.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);

//2.创建删除视频的request对象

DeleteVideoRequest request=new DeleteVideoRequest();

//3.向request设置视频id

request.setVideoIds(id);

//4.调用初始化对象的方法实现删除

client.getAcsResponse(request);

} catch (Exception e) {

e.printStackTrace();

throw new GuliException(20001,"删除视频失败");

}

}
