vod微服务中添加service方法

## 1 创建工具类 ##

service\_vod中创建AliyunVodSDKUtils.java

/**
    * @className: AliyunVodSDKUtils
    * @description: 阿里云视频工具类
    * @date: 2020/12/13
    * @author: cakin
    */
    public class AliyunVodSDKUtils {
        /**
         * client初始化
         *
         * @param accessKeyId     accessKeyId
         * @param accessKeySecret accessKeySecret
         * @return DefaultAcsClient 客户端
         */
        public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) {
            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;
        }
    }

## 2 Service ##

接口

/**
    * 功能描述：删除视频
    *
    * @author cakin
    * @date 2020/12/13
    * @param videoId 视频id
    */
    void removeVideo(String videoId) throws ClientException;

实现

/**
    * 功能描述：删除视频
    *
    * @param videoId 视频id
    * @author cakin
    * @date 2020/12/13
    */
    @Override
    public void removeVideo(String videoId) throws ClientException {
        DefaultAcsClient client = AliyunVodSDKUtils.initVodClient(
                vodProperties.getKeyid(),
                vodProperties.getKeysecret());
        DeleteVideoRequest request = new DeleteVideoRequest();
        request.setVideoIds(videoId);
        client.getAcsResponse(request);
    }

## 3 控制器 ##

/**
    * 功能描述：删除视频
    *
    * @author cakin
    * @date 2020/12/13
    * @param vodId 视频id
    * @return R 返回给前端的数据
    */
    @DeleteMapping("remove/{vodId}")
    public R removeVideo(
            @ApiParam(name = "vodId", value = "阿里云视频id", required = true)
            @PathVariable String vodId) {
        log.warn("service-vod MediaController：videoSourceId= " + vodId);
        try {
            videoService.removeVideo(vodId);
            return R.ok().message("视频删除成功");
        } catch (Exception e) {
            log.error(ExceptionUtils.getMessage(e));
            throw new GuliException(ResultCodeEnum.VIDEO_DELETE_ALIYUN_ERROR);
        }
    }

# 二 前端 #

## 1 定义api ##

// 删除视频
      removeByVodId(id) {
        return request({
          baseURL: 'http://127.0.0.1:8130',
          url: `/admin/vod/media/remove/${id}`,
          method: 'delete'
        })
      }

## 2 组件方法 ##

:before-remove="handleBeforeRemove"
              :on-remove="handleOnRemove"
    
    import vodApi from '@/api/vod'
        // 删除视频
        handleOnRemove(file, fileList) {
          if (!this.video.videoSourceId) {
            return
          }
    
          vodApi.removeByVodId(this.video.videoSourceId).then(response => {
            this.video.videoSourceId = ''
            this.video.videoOriginalName = ''
            // 删除视频的同时更新video数据信息
            videoApi.updateById(this.video)
            this.$message.success(response.message)
          })
        },

# 三 删除video的同时删除视频 #

## 1 创建feign接口 ##

@Service
    @FeignClient(value = "service-vod", fallback = VodMediaServiceFallBack.class)
    public interface VodMediaService {
    
    
        /**
         * 功能描述：根据 vodId 删除视频
         *
         * @author cakin
         * @date 2020/12/13
         * @param vodId 视频id
         * @return R 返回给前端的数据
         */
        @DeleteMapping("/admin/vod/media/remove/{vodId}")
        R removeVideo(@PathVariable("vodId") String vodId);
    }

## 2 创建容错类 ##

@Service
    @Slf4j
    public class VodMediaServiceFallBack implements VodMediaService {
        /**
         * 功能描述：容错保护
         *
         * @author cakin
         * @date 2020/12/13
         * @param vodId 视频id
         * @return R 返回给前端的数据
         */
        @Override
        public R removeVideo(String vodId) {
            log.info("熔断保护");
            return R.error();
        }
    }

## 3 service层中调用feign接口 ##

接口

/**
    * 功能描述：根据id删除视频
    *
    * @author cakin
    * @date 2020/12/13
    * @param id 视频id
    */
    void removeMediaVideoById(String id);

实现

/**
    * 功能描述：根据id删除视频
    *
    * @param id 视频id
    * @author cakin
    * @date 2020/12/13
    */
    @Override
    public void removeMediaVideoById(String id) {
        log.warn("VideoServiceImpl：video id = " + id);
        // 根据videoid找到视频id
        Video video = baseMapper.selectById(id);
        String videoSourceId = video.getVideoSourceId();
        log.warn("VideoServiceImpl：videoSourceId= " + videoSourceId);
        vodMediaService.removeVideo(videoSourceId);
    }

## 4 控制器 ##

/**
    * 功能描述：根据ID删除课时
    *
    * @param id 课时id
    * @return R 返回给前端的数据
    * @author cakin
    * @date 2020/12/8
    */
    @ApiOperation("根据ID删除课时")
    @DeleteMapping("remove/{id}")
    public R removeById(@ApiParam(value = "课时ID", required = true) @PathVariable String id) {
        log.warn("VideoController：video id = " + id);
        // 删除视频
        videoService.removeMediaVideoById(id);
        boolean result = videoService.removeById(id);
        if (result) {
            return R.ok().message("删除成功");
        } else {
            return R.error().message("数据不存在");
        }
    }
