spring boot整合阿里云视频点播上传 删除视频

一、创建视频点播微服务

1、创建微服务模块

Artifact：service-vod

2、pom

（1）service-vod中引入依赖

<dependencies>
        <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>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
        </dependency>
        <dependency>
            <groupId>org.json</groupId>
            <artifactId>json</artifactId>
        </dependency>
        <dependency>
            <groupId>com.google.code.gson</groupId>
            <artifactId>gson</artifactId>
        </dependency>

        <dependency>
            <groupId>joda-time</groupId>
            <artifactId>joda-time</artifactId>
        </dependency>
    </dependencies>

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
#阿里云 vod
#不同的服务器，地址不同
aliyun.vod.file.keyid=******
aliyun.vod.file.keysecret=********
# 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
# nacos服务地址
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

4、启动类

@EnableDiscoveryClient//nacos服务注册
@ComponentScan(basePackages = {"com.atguigu"})//扫描不同模块的配置类
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class) //不加载数据库相关配置
public class VodApplication {
    public static void main(String[] args) {
        SpringApplication.run(VodApplication.class, args);
    }
}

二、整合阿里云vod实现视频上传

1、创建常量类

ConstantPropertiesUtil.java 属性有密钥和id

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

}

2、复制工具类到项目中

public class InitObject {

    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 创建service

@Service
public class VodServiceImpl implements VodService {
    @Override
    public String uploadAlyiVideo(MultipartFile file) { //上传视频到阿里云
        String accessKeyId = ConstantVodUtils.ACCESS_KEY_ID; //id
        String accessKeySecret = ConstantVodUtils.ACCESS_KEY_SECRET; // 密钥
        String fileName = file.getOriginalFilename(); //上传文件原始名称
        String title = fileName.substring(0, fileName.lastIndexOf(".")); // 上传之后显示的名称
        String videoId;
        try {
            InputStream inputStream = file.getInputStream(); //上传文件输入流
            UploadStreamRequest request = new UploadStreamRequest(accessKeyId, accessKeySecret, title, fileName, inputStream);
            UploadVideoImpl uploader = new UploadVideoImpl();
            UploadStreamResponse response = uploader.uploadStream(request);
            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();
            }
        } catch (IOException e) {
            e.printStackTrace();
            return null;
        }
        return videoId;
    }

    @Override
    public void removeMoreAlyVideo(List<String> videoIdList) { //删除多个阿里云视频
        try {
            //1 初始化对象
            DefaultAcsClient defaultAcsClient = InitObject.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
            //2 创建删除视频的request对象
            DeleteVideoRequest deleteVideoRequest = new DeleteVideoRequest();
            //3 向request设置视频id
                //讲videoIdList中的值变为1，2，3的形式
            String join = StringUtils.join(videoIdList, ",");
            deleteVideoRequest.setVideoIds(join);
            //4 调用初始化对象的方法进行删除
            defaultAcsClient.getAcsResponse(deleteVideoRequest);
        }catch (Exception e){
            e.printStackTrace();
        }
    }
}

4 创建controller

@RequestMapping("/eduvod/video")
@RestController
public class VodController {
    @Autowired
    VodService vodService;
    //上传视频到阿里云
    @PostMapping("uploadAlyiVideo")
    public R uploadAlyiVideo(MultipartFile file){
        String videoId = vodService.uploadAlyiVideo(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 {
            //1 初始化对象
            DefaultAcsClient defaultAcsClient = InitObject.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
            //2 创建删除视频的request对象
            DeleteVideoRequest deleteVideoRequest = new DeleteVideoRequest();
            //3 向request设置视频id
            deleteVideoRequest.setVideoIds(id);
            //4 调用初始化对象的方法进行删除
            defaultAcsClient.getAcsResponse(deleteVideoRequest);
            return R.ok();
        }catch (Exception e){
            e.printStackTrace();
        }
        return R.error();
    }
    //删除多个阿里云视频
    @DeleteMapping("delete-bath")
    public R deleteBath(@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 =
                    InitObject.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
            //创建获取凭证的request对象和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){
            e.printStackTrace();
        }
        return R.error();
    }
}
