    </section>
    <!-- /讲师介绍 结束 -->
  </div>
</template>
<script>
export default {};
</script>

二、讲师列表页

一、后端开发

1. controller层

TeacherFrontController

@RestController
@CrossOrigin
@RequestMapping("/eduservice/teacherfront")
public class TeacherFrontController {

    @Autowired
    private EduTeacherService teacherService;

    // 分页查询讲师的方法
    @PostMapping("getTeahcerFrontList/{page}/{limit}")
    public R getTeacherFrontList(@PathVariable long page, @PathVariable long limit) {
        Page<EduTeacher> pageTeacher = new Page<>(page,limit);
        Map<String, Object> map = teacherService.getTeacherFrontList(pageTeacher);

        // 返回分页所有数据
        return R.ok().data(map);

    }
}

2. service层

• EduTeacherService

    // 分页查询讲师的方法
      Map<String, Object> getTeacherFrontList(Page<EduTeacher> pageTeacher);

• EduTeacherServiceImpl

  // 分页查询讲师的方法
      @Override
      public Map<String, Object> getTeacherFrontList(Page<EduTeacher> pageTeacher) {
  
          QueryWrapper<EduTeacher> wrapper = new QueryWrapper<>();
          wrapper.orderByDesc("id");
          //把分页数据封装到pageTeacher对象
          baseMapper.selectPage(pageTeacher, wrapper);
  
          // 把分页数据获取出来，放到map集合
          Map<String, Object> map = new HashMap<>();
  
          //总记录数
          long total = pageTeacher.getTotal();
          //当前页
          long current = pageTeacher.getCurrent();
          //每页记录数
          long size = pageTeacher.getSize();
          //查询到的对象
          List<EduTeacher> teacherList = pageTeacher.getRecords();
          //总页数
          long pages = pageTeacher.getPages();
          //是否有上一页
          boolean hasPrevious = pageTeacher.hasPrevious();
          //是否有下一页
          boolean hasNext = pageTeacher.hasNext();
  
          //将数据封装到map中返回
          map.put("total", total);
          map.put("current", current);
          map.put("size", size);
          map.put("list", teacherList);
          map.put("hasPrevious", hasPrevious);
          map.put("hasNext", hasNext);
          map.put("pages", pages);
  
          return map;
      }

3. swagger测试

二、前端列表js

1. 创建api

创建文件夹api，api下创建teacher.js，用于封装讲师模块的请求

import request from '@/utils/request'

export default{

    // 分页讲师查询的方法
    getTeacherList(page, limit) {
        return request({
            url: `/eduservice/teacherfront/getTeahcerFrontList/${page}/${limit}`,
            method: 'post'
        })
    }

}

2. 讲师列表组件中调用api

<script>
import teacherAPI from "@/api/teacher";

export default {
       //异步调用，进页面调用，且只会调一次
      //params：相当于之前的 this.$route.params.id 等价 params.id
      //error：错误信息
      asyncData({ params, error }) {
        return teacherApi.getTeacherList(1, 8)
          .then(response => {
              //this.data = response.data.data
              return { data: response.data.data }
        });
      },
};
</script>

三、页面渲染

1. 页面模板

<template>
    <div id="aCoursesList" class="bg-fa of">
        <!-- 讲师列表 开始 -->
        <section class="container">
            <section class="c-sort-box unBr">
                <div>
                <!-- 无数据提示 开始-->
                <!-- /无数据提示 结束-->
                <!-- 数据列表 开始-->
                <!-- /数据列表 结束-->
                </div>
            <!-- 公共分页 开始 -->
            <!-- /公共分页 结束 -->
            </section>
        </section>
        <!-- /讲师列表 结束 -->
    </div>
</template>

2. 无数据提示

添加：v-if="data.total==0"

 <!-- /无数据提示 开始-->
          <section class="no-data-wrap" v-if="data.total==0">
            <em class="icon30 no-data-ico">&nbsp;</em>
            <span class="c-666 fsize14 ml10 vam"
              >没有相关数据，小编正在努力整理 中...</span
            >
          </section>
          <!-- /无数据提示 结束-->

3. 列表

<article class="i-teacher-list" v-if="data.total > 0">
              <ul class="of">
                  <li v-for="item in data.items" :key="item.id">
                      <section class="i-teach-wrap">
                          <div class="i-teach-pic">
                              <a href="/teacher/1" :title="item.name" target="_blank">
                                  <img :src="item.avatar" :alt="item.name" />
                              </a>
                          </div>
                          <div class="mt10 hLh30 txtOf tac">
                             <a :href="'/teacher/'+item.id" :title="item.name" class="fsize18 c-666">{{ item.name }}</a>
                          </div>
                          <div class="hLh30 txtOf tac">
                             <span class="fsize14 c-999" >{{ item.career }}</span>
                          </div>
                          <div class="mt15 i-q-txt">
                              <p class="c-999 f-fA">{{item.career}}</p>
                          </div>
                      </section>
                  </li>
              </ul>
              <div class="clear"></div>
          </article>

4. 测试

四、分页

1. 分页方法

methods: {
        // 分页切换的方法
        //参数是页码数
        gotoPage(page) {
          teacherApi.getTeacherList(page, 8)
            .then(response => {
              this.data = response.data.data
            })
        }
      }

2. 分页页面渲染

 <!-- 公共分页 开始 -->
        <div>
            <div class="paging">
                <!-- undisable这个class是否存在，取决于数据属性hasPrevious -->
                <a
                  :class="{ undisable: !data.hasPrevious }"
                  href="#"
                  title="首页"
                  @click.prevent="gotoPage(1)"
                  >首页</a>
                <a
                  :class="{ undisable: !data.hasPrevious }"
                  href="#"
                  title="前一页"
                  @click.prevent="gotoPage(data.current - 1)"
                  >&lt;</a
                    >
                <a
                  v-for="page in data.pages"
                  :key="page"
                  :class="{
                          current: data.current == page,
                          undisable: data.current == page,
                          }"
                  :title="'第' + page + '页'"
                  href="#"
                  @click.prevent="gotoPage(page)"
                  >{{ page }}</a
                    >
                <a
                  :class="{ undisable: !data.hasNext }"
                  href="#"
                  title="后一页"
                  @click.prevent="gotoPage(data.current + 1)"
                  >&gt;</a
                    >
                <a
                  :class="{ undisable: !data.hasNext }"
                  href="#"
                  title="末页"
                  @click.prevent="gotoPage(data.pages)"
                  >末页</a
                    >
                <div class="clear" />
            </div>
        </div>
        <!-- 公共分页 结束 -->

3. 测试

三、讲师详情页

一、后端开发

1. controller层

TeacherFrontController

@RestController
@CrossOrigin
@RequestMapping("/eduservice/teacherfront")
public class TeacherFrontController {

    @Autowired
    private EduTeacherService teacherService;

    @Autowired
    private EduCourseService courseService;

    // 根据id查询讲师信息（讲师本身信息 + 讲师所讲课程信息）
    @GetMapping("/getTeacherFrontInfo/{teacherId}")
    public R getTeacherFrontInfo(@PathVariable String teacherId) {
        //1.根据讲师id查询讲师基本信息
        EduTeacher eduTeacher = teacherService.getById(teacherId);

        //2.根据讲师id查询所讲课程
        QueryWrapper<EduCourse> wrapper = new QueryWrapper<>();
        wrapper.eq("teacher_id", teacherId);
        List<EduCourse> courseList = courseService.list(wrapper);

        return R.ok().data("teacher", eduTeacher).data("courseList", courseList);
        
    }

}

2. Swagger测试

二、前端开发

1. 定义api

api/teacher.js:

// 讲师详情的方法
    getTeacherInfo(id) {
        return request({
            url: `/eduservice/teacherfront/getTeacherFrontInfo/${id}`,
            method: 'get'
        })
    }

2. 讲师详情页中调用api

pages/teacher/_id.vue:

import teacherApi from '@/api/teacher'

export default {

   asyncData({ params, error }) {
    return teacherApi.getTeacherInfo(params.id)
      .then(response => {
            // console.log(response)
            return { 
              teacher: response.data.data.teacher,
              courseList: response.data.data.courseList
            }
       })
  }

}
</script>

三、页面渲染

1. 讲师基本信息模板

          </article>

5. 测试

• 讲师列表

• 有课程

• 没有课程

首页课程功能

课程列表页面

一、后端接口开发

1. 实体类

创建 frontvo 包，在改包下创建 CourseFrontVo 实体类：

@Data
public class CourseFrontVo {
    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;
}

2. controller层

CourseFrontController

@RestController
@CrossOrigin
@RequestMapping("/eduservice/coursefront")
public class CourseFrontController {
    
    @Autowired
    private EduCourseService courseService;

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

        // 返回分页所有数据
        return R.ok().data(map);
    }

}

3. service层

EduCourseService:

// 条件查询带分页查询课程
    Map<String, Object> getCourseFrontList(Page<EduCourse> pageCourse, CourseFrontVo courseFrontVo);

EduCourseServiceImpl:

 // 条件查询带分页查询课程
    @Override
    public Map<String, Object> getCourseFrontList(Page<EduCourse> pageParam, CourseFrontVo courseFrontVo) {
        QueryWrapper<EduCourse> wrapper = new QueryWrapper<>();
        // 判断条件值是否为空，不为空则拼接
        if (!StringUtils.isEmpty(courseFrontVo.getSubjectParentId())) { //一级分类
            wrapper.eq("subject_parent_id", courseFrontVo.getSubjectId());
        }

        if (!StringUtils.isEmpty(courseFrontVo.getSubjectId())) { //二级分类
            wrapper.eq("subject_id", courseFrontVo.getSubjectId());
        }

        if (!StringUtils.isEmpty(courseFrontVo.getBuyCountSort())) { //关注度
            wrapper.orderByDesc("buy_count");
        }

        if (!StringUtils.isEmpty(courseFrontVo.getGmtCreateSort())) { //最新，创建时间
            wrapper.orderByDesc("gmt_create");
        }

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

        baseMapper.selectPage(pageParam, wrapper);

        // 把分页数据获取出来，放到map集合
        Map<String, Object> map = new HashMap<>();

        //总记录数
        long total = pageParam.getTotal();
        //当前页
        long current = pageParam.getCurrent();
        //每页记录数
        long size = pageParam.getSize();
        //查询到的对象
        List<EduCourse> records = pageParam.getRecords();
        //总页数
        long pages = pageParam.getPages();
        //是否有上一页
        boolean hasPrevious = pageParam.hasPrevious();
        //是否有下一页
        boolean hasNext = pageParam.hasNext();

        //将数据封装到map中返回
        map.put("total", total);
        map.put("current", current);
        map.put("size", size);
        map.put("items", records);
        map.put("hasPrevious", hasPrevious);
        map.put("hasNext", hasNext);
        map.put("pages", pages);

        return map;

    }

二、课程列表前端

1. 定义api

api/course.js

import request from '@/utils/request'

export default{

   // 条件分页课程查询的方法
   getCourseList(page, limit, searchObj) {
       return request({
           url: `/eduservice/coursefront/getFrontCourseList/${page}/${limit}`,
           method: 'post',
           data: searchObj
       })
   },

   // 查询所有分类的方法
   getAllSubject() {
       return request({
           url: `/eduservice/subject/getAllSubject`,
           method: 'get'
       })
   }
}

2. 页面调用接口

pages/course/index.vue

<script>
import courseApi from '@/api/course'

export default {
  data() {
    return {
      page:1, //当前页
      data:{},  //课程列表
      subjectNestedList: [], // 一级分类列表
      subSubjectList: [], // 二级分类列表

      searchObj: {}, // 查询表单对象

      oneIndex:-1,
      twoIndex:-1,
      buyCountSort:"",
      gmtCreateSort:"",
      priceSort:""
    }
  },

  created() {
    //课程第一次查询
    this.initCourseFirst()
    //一级分类显示
    this.initSubject()
  },
  methods:{
    //1 查询第一页数据
    initCourseFirst() {
      courseApi.getCourseList(1,8,this.searchObj).then(response => {
        this.data = response.data.data
      })
    },

    //2 查询所有一级分类
    initSubject() {
      courseApi.getAllSubject()
        .then(response => {
          this.subjectNestedList = response.data.data.list
        })
    },

    //3 分页切换的方法
    gotoPage(page) {
      courseApi.getCourseList(page,8,this.searchObj).then(response => {
        this.data = response.data.data
      })
    },

    //4 点击某个一级分类，查询对应二级分类
    searchOne(subjectParentId,index) {
      //把传递index值赋值给oneIndex,为了active样式生效
      this.oneIndex = index

      this.twoIndex = -1
      this.searchObj.subjectId = ""
      this.subSubjectList = []

      //把一级分类点击id值，赋值给searchObj
      this.searchObj.subjectParentId = subjectParentId
      //点击某个一级分类进行条件查询
      this.gotoPage(1)

      //拿着点击一级分类id 和 所有一级分类id进行比较，
      //如果id相同，从一级分类里面获取对应的二级分类
      for(let i=0;i<this.subjectNestedList.length;i++) {
        //获取每个一级分类
        var oneSubject = this.subjectNestedList[i]
        //比较id是否相同
        if(subjectParentId == oneSubject.id) {
          //从一级分类里面获取对应的二级分类
          this.subSubjectList = oneSubject.children
        }
      }
    },

    //5 点击某个二级分类实现查询
    searchTwo(subjectId, index) {
      //把index赋值,为了样式生效
      this.twoIndex = index
      //把二级分类点击id值，赋值给searchObj
      this.searchObj.subjectId = subjectId
      //点击某个二级分类进行条件查询
      this.gotoPage(1)
    },

    //6 根据销量排序
    searchBuyCount() {
      //设置对应变量值，为了样式生效
      this.buyCountSort = "1"
      this.gmtCreateSort = ""
      this.priceSort = ""

      //把值赋值到searchObj
      this.searchObj.buyCountSort = this.buyCountSort
      this.searchObj.gmtCreateSort = this.gmtCreateSort
      this.searchObj.priceSort = this.priceSort

      //调用方法查询
      this.gotoPage(1)
    },

    //7 最新排序
    searchGmtCreate() {
      //设置对应变量值，为了样式生效
      this.buyCountSort = ""
      this.gmtCreateSort = "1"
      this.priceSort = ""

      //把值赋值到searchObj
      this.searchObj.buyCountSort = this.buyCountSort

4. 测试

课程详情页

一、后端开发

1. 实体类

CourseWebVo

@Data
public class CourseWebVo {
    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;
}

#### 2. controller层
CourseFrontController

 //课程详情的方法
    @GetMapping("getFrontCourseInfo/{courseId}")
    public R getFrontCourseInfo(@PathVariable String courseId) {
        //根据课程id，编写sql语句查询课程信息
        CourseWebVo courseWebVo = courseService.getBaseCourseInfo(courseId);

        //根据课程id查询章节和小节
        List<ChapterVo> chapterVoList = chapterService.getChapterVideoByCourseId(courseId);

        return R.ok().data("courseWebVo",courseWebVo).data("chapterVoList",chapterVoList);
    }

3. service层

• EduCourseService

   //根据课程id，编写sql语句查询课程信息
      CourseWebVo getBaseCourseInfo(String courseId);

• EduCourseServiceImpl

  //根据课程id，编写sql语句查询课程信息
      @Override
      public CourseWebVo getBaseCourseInfo(String courseId) {
          return baseMapper.getBaseCourseInfo(courseId);
      }

4. dao层

@Mapper
public interface EduCourseMapper extends BaseMapper<EduCourse> {

    public CoursePublishVo getPublishCourseInfo(String courseId);

    //根据课程id，编写sql语句查询课程信息
    CourseWebVo getBaseCourseInfo(String courseId);
}

EduCourseMapper.xml:

  <!--前台根据课程id，查询课程基础信息-->
    <select id="getBaseCourseInfo" resultType="com.atguigu.eduservice.entity.frontvo.CourseWebVo">
        SELECT
            ec.id,
            ec.title,
            ec.cover,
            ec.lesson_num AS lessonNum,
            ec.price,
            ec.cover,
            ec.buy_count as buyCount,
            ec.view_count as viewCount,
            esd.description,
            s1.title AS subjectLevelOne,
            s1.id as subjectLevelOneId,
            s2.id as subjectLevelTwoId,
            s2.title AS subjectLevelTwo,
            t.name AS teacherName,
            t.id as teacherId,
            t.avatar,
            t.intro
        FROM
            edu_course ec
                LEFT JOIN edu_teacher t ON ec.teacher_id = t.id
                LEFT JOIN edu_subject s1 ON ec.subject_parent_id = s1.id
                LEFT JOIN edu_subject s2 ON ec.id = s2.id
                left join edu_course_description esd on ec.id = esd.id
        WHERE
            ec.id = #{id}
    </select>

5. 测试

二、前端开发

1. 定义api

api/course.js

 //课程详情的方法
    getCourseInfo(courseId) {
        return request({
            url: `/eduservice/coursefront/getFrontCourseInfo/${courseId}`,
            method: 'get'
        })
    }

2. 页面调用接口

pages/course/_id.vue

<script>
import courseApi from "@/api/course"

export default {
    asyncData({ params, error }) {
    return courseApi.getCourseInfo(params.id).then(response => {
      return { 
        courseWebVo: response.data.data.courseWebVo,
        chapterVideoList: response.data.data.chapterVideoList
      }
    })
  }
};
</script>

3. 前端页面

<template>
  <div id="aCoursesList" class="bg-fa of">
    <!-- /课程详情 开始 -->
    <section class="container">
      <section class="path-wrap txtOf hLh30">

1. 视频播放器介绍

阿里云播放器SDK（ApsaraVideo Player SDK）是阿里视频服务的重要一环，除了支持点播和直播的基础播放功能外，深度融合视频云业务，如支持视频的加密播放、安全下载、清晰度切换、直播答题等业务场景，为用户提供简单、快速、安全、稳定的视频播放服务。

2. 集成视频播放器

参考文档：https://help.aliyun.com/document_detail/51991.html
参考 【播放器简单使用说明】一节

• 引入脚本文件和css文件

  <link rel="stylesheet"
  href="https://g.alicdn.com/de/prismplayer/2.8.1/skins/default/aliplayer-min.css" />
  
  <script charset="utf-8" type="text/javascript"
  src="https://g.alicdn.com/de/prismplayer/2.8.1/aliplayer-min.js"></script>

• 初始化视频播放器

  <body>
      <div class="prism-player" id="J_prismPlayer"></div>
      <script>
          var player = new Aliplayer({
              id: 'J_prismPlayer',
               width: '100%',
                autoplay: false,
              cover: 'http://liveroom-img.oss-cn-qingdao.aliyuncs.com/logo.png',
              
              //播放配置
          },function(player){
              console.log('播放器创建好了。')
          });
      </script>
  </body>

3. 播放地址播放

在Aliplayer的配置参数中添加如下属性：

//播放方式一：支持播放地址播放,此播放优先级最高，此种方式不能播放加密视频
source : '你的视频播放地址',

启动浏览器运行，测试视频的播放。

4. 播放凭证播放（推荐）

阿里云播放器支持通过播放凭证自动换取播放地址进行播放，接入方式更为简单，且安全性更高。播放凭证默认时效为100秒（最大为3000秒），只能用于获取指定视频的播放地址，不能混用或重复使用。如果凭证过期则无法获取播放地址，需要重新获取凭证。

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
vid : '视频id',
playauth : '视频授权码',

注意：播放凭证有过期时间，默认值：100秒 。取值范围：100~3000。
设置播放凭证的有效期。
在获取播放凭证的测试用例中添加如下代码。

request.setAuthInfoTimeout(200L);

在线配置参考：https://player.alicdn.com/aliplayer/setting/setting.htmlspm=a2c4g.11186623.2.16.242c6782Kdc4Za
 

整合阿里云视频播放器

一、后端获取播放凭证

1. controller层

VodController

//根据视频id获取视频凭证
    @GetMapping("/getPlayAuth/{id}")
    public R getPlayAuth(@PathVariable String id){
        try {
            //初始化
            DefaultAcsClient client = InitVodClient.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);

            //请求
            GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
            request.setVideoId(id);

            //响应
            GetVideoPlayAuthResponse response = client.getAcsResponse(request);

            //得到播放凭证
            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");
        }
    }

2. Swagger测试

二、前端播放器整合

1. 点击播放超链接

course/_id.vue

<a :href="'/player/'+video.videoSourceId"  :title="video.title"  target="_blank">

2. 定义api

api/vod.js

import request from '@/utils/request'

export default{
    //根据视频id，获取视频凭证
    getPlayAuthById(id){
        return request({
            url:`/eduvod/video/getPlayAuth/${id}`,
            method: 'get'
        })
    }
}

3. 页面

<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>

<script>
import vod from "@/api/vod"

export default {
    layout: "video", //应用video布局
    asyncData({ params, error }) {
    return vod.getPlayAuthById(params.vid).then((response) => {
      return {
        playAuth: response.data.data.playAuth,
        vid: params.vid
      }
    })
  },

   mounted() {
    //页面渲染之后  created
    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",
        // 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
        useH5Prism: true, // 播放器类型：html5
      },function (player) {
        console.log("播放器创建成功");
      }
    )
  }

}
</script>
