讲师详情页实现

一 后端

1 service

接口

/**
* 功能描述：根据讲师id获取讲师详情页数据
*
* @author cakin
* @date 2020/12/18
* @param id
* @return
* @description:
*/
Map<String, Object> selectTeacherInfoById(String id);

实现

/**
* 功能描述：根据讲师id获取讲师详情页数据
*
* @param id 讲师id
* @return Map<String, Object> 封装讲师信息和课程信息
* @author cakin
* @date 2020/12/18
* @description:
*/
@Override
public Map<String, Object> selectTeacherInfoById(String id) {
    Teacher teacher = baseMapper.selectById(id);
    QueryWrapper<Course> courseQueryWrapper = new QueryWrapper<>();
    courseQueryWrapper.eq("teacher_id", id);
    List<Course> courseList = courseMapper.selectList(courseQueryWrapper);
    Map<String, Object> map = new HashMap<>();
    // 讲师信息
    map.put("teacher", teacher);
    // 课程列表
    map.put("courseList", courseList);
    return map;
}

2 web层

/**
* 功能描述：获取讲师
*
* @param id 讲师id
* @return R 返回给前端的数据
* @author cakin
* @date 2020/12/18
* @description:
*/
@ApiOperation(value = "获取讲师")
@GetMapping("get/{id}")
public R get(@ApiParam(value = "讲师ID", required = true) @PathVariable String id) {
    Map<String, Object> map = teacherService.selectTeacherInfoById(id);
    return R.ok().data(map);
}

二 前端

1 api

  // 获取讲师
  getById(id) {
    return request({
      url: `/api/edu/teacher/get/${id}`,
      method: 'get'
    })
  }

2 页面脚本

<script>
import teacherApi from '~/api/teacher'
export default {

  // asyncData被调用的时候，第一个参数被设定为当前页面的上下文对象
  // 使用同步调用
  async asyncData(page) {
    const response = await teacherApi.getById(page.route.params.id)
    return {
      teacher: response.data.teacher,
      courseList: response.data.courseList
    }
  }
}
</script>

3 模板部分

<template>
  <div id="aCoursesList" class="bg-fa of">
    <!-- 讲师介绍 开始 -->
