1.application.properties

server.port=8003

spring.application.name=service-vod


spring.profiles.active=dev


spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848


aliyun.vod.file.keyid=LTAI4FvvVEWiTJ3GNJJqJnk7
aliyun.vod.file.keysecret=9st82dv7EvFk9mTjYO1XXbM632fRbG


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

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

2.配置类

1）获取id和密钥工具类

@Component
public class ConstantVodUtils implements InitializingBean {

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

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

    public static String ACCESS_KEY_SECRET;
    public static String ACCESS_KEY_ID;

    @Override
    public void afterPropertiesSet() throws Exception {
        ACCESS_KEY_ID = keyid;
        ACCESS_KEY_SECRET = keysecret;
    }
}

2）初始化工具类

public class InitVodCilent {

    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代码

controller类

@RestController
@RequestMapping("/eduvod/video")
@CrossOrigin
public class VodController {

    @Autowired
    private VodService vodService;

    //上传视频到阿里云
    @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);
    }

    //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 GuliException(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 videoIdList) {
        vodService.removeMoreAlyVideo(videoIdList);
        return R.ok();
    }

    //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 GuliException(20001,"获取凭证失败");
        }
    }
}

2)serive类

public class VodServiceImpl implements VodService {

    @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;
        }

    }

    @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 GuliException(20001,"删除视频失败");
        }
    }

    public static void main(String[] args) {
        List 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);
    }
}
