阿里云视频点播功能

httpclient技术可以调用api地址http://vod.cn-shanghai.aliyunes.com/Action=GetPlayInfo&VideoId=1223

API: 阿里云提供固定的地址，只需要调用这个固定的地址，向地址传递参数，实现功能。

SDK:sdk对api方式进行封装，更方便使用，之前使用EasyExcel调用阿里云提供类或者接口里面的方法实现视频功能。

1.引入maven依赖

　　　　 <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-core</artifactId>
        </dependency>
        <dependency>
            <groupId>com.aliyun.oss</groupId>
            <artifactId>aliyun-sdk-oss</artifactId>
        </dependency>
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-vod</artifactId>
        </dependency>
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-sdk-vod-upload</artifactId>
        </dependency>

2.由于aliyun-java-vod-upload-1.4.9.jar还未正式开源，需要直接引入jar包到项目中，这个依赖不能直接在maven中央仓库下载到，手动把依赖安装到本地仓库里面。使用maven命令进行安装。 进入lib 目录执行下面命令

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.jar

3. application.properties

# 服务端口
server.port=8003
# 服务名
spring.application.name=service-vod

# 环境设置：dev、test、prod
spring.profiles.active=dev

# nacos服务地址
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

#阿里云 vod
#不同的服务器，地址不同
aliyun.vod.file.keyid=LTAI4GDTqjJkxrB353q44ejE
aliyun.vod.file.keysecret=rdy8GeTHEYeKOGrY1EJ8pKGdQodMSv

# 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

 4.utils

@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;
    }
}

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;
    }
}

5.controller

@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<String> videoIdList) {
        vodService.removeMoreAlyVideo(videoIdList);
        return R.ok();
    }
}

6.service

@Service
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<String> list = new ArrayList<>();
        list.add("11");
        list.add("22");
