一、课程列表

1、课程列表【后端】

1.1、在entity/frontvo文件夹下创建课程列表CourseQueryVo类

43.首页课程功能
@ApiModel(value = "课程查询对象", description = "课程查询对象封装")
@Data
public class CourseQueryVo implements Serializable {
    private static final long serialVersionUID = 1L;

    @ApiModelProperty(value = "课程名称")
    private String title;

    @ApiModelProperty(value = "讲师id")
    private String teacherId;

    @ApiModelProperty(value = "一级类别id")
    private String subjectParentId;

    @ApiModelProperty(value = "二级类别id")
    private String subjectId;

    @ApiModelProperty(value = "销量排序")
    private String buyCountSort;

    @ApiModelProperty(value = "最新时间排序")
    private String gmtCreateSort;

    @ApiModelProperty(value = "价格排序")
    private String priceSort;
}
View Code

1.2、在controller/front文件夹下创建CourseFrontController类

43.首页课程功能
@RestController
@RequestMapping("/eduservice/coursefront")
@CrossOrigin
public class CourseFrontController {
    @Autowired
    private EduCourseService courseService;

    @Autowired
    private EduChapterService chapterService;

    //1 条件查询带分页查询课程
    @PostMapping("getCourseFrontList/{page}/{limit}")
    public R getCourseFrontList(@PathVariable long page,@PathVariable long limit,
                                 @RequestBody(required = false) CourseQueryVo courseQueryVo) {
        Page<EduCourse> pageCourse = new Page<>(page, limit);
        Map<String,Object> map = courseService.getCourseFrontList(pageCourse,courseQueryVo);

        //返回分页所有数据

        return R.ok().data(map);
    }
}
View Code

1.3、在EduCourseServiceImpl中实现getCourseFrontList方法

43.首页课程功能
@Override
    public Map<String, Object> getCourseFrontList(Page<EduCourse> pageParam, CourseQueryVo courseQueryVo) {
        QueryWrapper<EduCourse> wrapper = new QueryWrapper<>();
        //判断条件值是否为空，不为空则拼接
        if(!StringUtils.isEmpty(courseQueryVo.getSubjectParentId())){//一级分类
            wrapper.eq("subject_parent_id",courseQueryVo.getSubjectParentId());
        }
        if(!StringUtils.isEmpty(courseQueryVo.getSubjectId())){//二级分类
            wrapper.eq("subject_id",courseQueryVo.getSubjectId());
        }
        if (!StringUtils.isEmpty(courseQueryVo.getBuyCountSort())) {//关注度排序
            wrapper.orderByDesc("buy_count");
        }

        if (!StringUtils.isEmpty(courseQueryVo.getGmtCreateSort())) {//最新排序
            wrapper.orderByDesc("gmt_create");
        }

        if (!StringUtils.isEmpty(courseQueryVo.getPriceSort())) {//价格排序
            wrapper.orderByDesc("price");
        }

        baseMapper.selectPage(pageParam,wrapper);
        List<EduCourse> records = pageParam.getRecords();
        long current = pageParam.getCurrent();
        long pages = pageParam.getPages();
        long size = pageParam.getSize();
        long total = pageParam.getTotal();
        boolean hasNext = pageParam.hasNext();
        boolean hasPrevious = pageParam.hasPrevious();

        Map<String, Object> map = new HashMap<String, Object>();
        map.put("items", records);
        map.put("current", current);
        map.put("pages", pages);
        map.put("size", size);
        map.put("total", total);
        map.put("hasNext", hasNext);
        map.put("hasPrevious", hasPrevious);

        return map;
    }

            method: 'post',
            data: searchObj
        })
    },
    // 获取所有分类分类
    getAllSubject() {
        return request({

二、课程详情页


1、课程详情【后端】

在项目中很多时候需要把model转换成dto用于网站信息的展示，按前端的需要传递对象的数据，保证model对外是隐私的，例如密码之类的属性能很好地避免暴露在外，同时也会减小数据传输的体积。

1.1、在entity/frontvo文件夹下创建课程详情对象类CourseWebVo.java

43.首页课程功能
@ApiModel(value="课程信息", description="网站课程详情页需要的相关字段")
@Data
public class CourseWebVo implements Serializable {

    private static final long serialVersionUID = 1L;

    private String id;

    @ApiModelProperty(value = "课程标题")
    private String title;

    @ApiModelProperty(value = "课程销售价格，设置为0则可免费观看")
    private BigDecimal price;

    @ApiModelProperty(value = "总课时")
    private Integer lessonNum;

    @ApiModelProperty(value = "课程封面图片路径")
    private String cover;

    @ApiModelProperty(value = "销售数量")
    private Long buyCount;

    @ApiModelProperty(value = "浏览数量")
    private Long viewCount;

    @ApiModelProperty(value = "课程简介")
    private String description;

    @ApiModelProperty(value = "讲师ID")
    private String teacherId;

    @ApiModelProperty(value = "讲师姓名")
    private String teacherName;

    @ApiModelProperty(value = "讲师资历,一句话说明讲师")
    private String intro;

    @ApiModelProperty(value = "讲师头像")
    private String avatar;

    @ApiModelProperty(value = "课程类别ID")
    private String subjectLevelOneId;

    @ApiModelProperty(value = "类别名称")
    private String subjectLevelOne;

    @ApiModelProperty(value = "课程类别ID")
    private String subjectLevelTwoId;

    @ApiModelProperty(value = "类别名称")
    private String subjectLevelTwo;

}

CourseMapper.xml

43.首页课程功能
    <!--sql语句：根据课程id查询课程详情-->
    <select id="getBaseCourseInfo" resultType="com.atguigu.eduservice.entity.frontvo.CourseWebVo">
      SELECT c.id,c.title,c.cover,
        CONVERT(c.price, DECIMAL(8,2)) AS price,
        c.lesson_num AS lessonNum,

        s2.id AS subjectLevelTwoId,
        s2.title AS subjectLevelTwo

      FROM
        edu_course c
        LEFT JOIN edu_course_description cd ON c.id = cd.id
        LEFT JOIN edu_teacher t ON c.teacher_id = t.id

四、小节视频播放功能


1、后端获取播放凭证


1.1、VideoController

service-vod微服务中创建 VideoController.java
controller中创建 getPlayAuth 接口方法
43.首页课程功能
//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 = InitVodClient.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,"获取视频凭证失败");
        }
    }


View Code

2.1、VideoVo


43.首页课程功能


2、前端播放器整合



2.1、点击播放超链接


course/_id.vue
修改课时目录超链接

43.首页课程功能
<a
   :href="'/player/'+video.videoSourceId"
   :title="video.title"
   target="_blank">


View Code


2.2、layout


因为播放器的布局和其他页面的基本布局不一致，因此创建新的布局容器 layouts/video.vue

43.首页课程功能
<template>
  <div class="guli-player">
    <div class="head">
      <a href="#" title="谷粒学院">
        <img class="logo" src="~/assets/img/logo.png" lt="谷粒学院">
    </a></div>
    <div class="body">
      <div class="content"><nuxt/></div>
    </div>
  </div>
</template>
<script>
export default {}
</script>

<style>
html,body{
  height:100%;
}
</style>

<style scoped>
.head {
  height: 50px;
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
}

.head .logo{
  height: 50px;
  margin-left: 10px;
}

.body {
  position: absolute;
  top: 50px;
  left: 0;
  right: 0;
  bottom: 0;
  overflow: hidden;
}
</style>


View Code


2.3、api


创建api模块 api/vod.js，从后端获取播放凭证


43.首页课程功能
import request from '@/utils/request'

export default {

  getPlayAuth(vid) {
    return request({
      url: `/eduvod/video/GetPlayAuth/${vid}`,
      method: 'get'
    })
  }

}

2.5、创建播放页面

创建 pages/player/_vid.vue
（1）引入播放器js库和css样式
43.首页课程功能
<template>
  <div>

    <!-- 阿里云视频播放器样式 -->
    <link rel="stylesheet" href="https://g.alicdn.com/de/prismplayer/2.8.1/skins/default/aliplayer-min.css" >
    <!-- 阿里云视频播放器脚本 -->
    <script charset="utf-8" type="text/javascript" src="https://g.alicdn.com/de/prismplayer/2.8.1/aliplayer-min.js" />

    <!-- 定义播放器dom -->
    <div id="J_prismPlayer" class="prism-player" />
  </div>
</template>


View Code

（2）获取播放凭证

43.首页课程功能
<script>
import vod from '@/api/vod'
export default { 
    layout: 'video',//应用video布局
    asyncData({ params, error }) {
        //params.vid为地址栏的视频id,vid为动态文件名
        return vod.getPlayAuth(params.vid).then(response => {
            // console.log(response.data.data)
            return {
            vid: params.vid,
            playAuth: response.data.data.playAuth
            }
        })
    }
}
</script>


View Code

（3）创建播放器

43.首页课程功能
 /**
 * 页面渲染完成时：此时js脚本已加载，Aliplayer已定义，可以使用
 * 如果在created生命周期函数中使用，Aliplayer is not defined错误
 */
mounted() {
    
    new Aliplayer({
        id: 'J_prismPlayer',
        vid: this.vid, // 视频id
        playauth: this.playAuth, // 播放凭证
        encryptType: '1', // 如果播放加密视频，则需设置encryptType=1，非加密视频无需设置此项
        width: '100%',
        height: '500px'
    }, function(player) {
        console.log('播放器创建成功')
    })
}


View Code

（4）其他常见的可选配置

43.首页课程功能
// 以下可选设置
cover: 'http://guli.shop/photo/banner/1525939573202.jpg', // 封面
qualitySort: 'asc', // 清晰度排序

mediaType: 'video', // 返回音频还是视频
autoplay: false, // 自动播放
isLive: false, // 直播
rePlay: false, // 循环播放
preload: true,
controlBarVisibility: 'hover', // 控制条的显示方式：鼠标悬停
