SpringBoot阿里云视频点播

LL.LEBRON 人气:0

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:

查看接入区域标识对应API/SDKRegionId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");
    }
}
