课程发布页面整合

1、添加隐藏路由

{
        path: 'add/:id',
        name: 'EduCourseInfoEdit',
        component: () => import('@/views/course/add'),
        meta: { title: '编辑课程基本信息', noCache: true },
        hidden: true
      },
      {
        path: 'chapter/:id',
        name: 'EduCourseChapterEdit',
        component: () => import('@/views/course/chapter'),
        meta: { title: '编辑课程大纲', noCache: true },
        hidden: true
      },
      {
        path: 'publish/:id',
        name: 'EduCoursePublishEdit',
        component: () => import('@/views/course/publish'),
        meta: { title: '发布课程', noCache: true },
        hidden: true
      },

2、创建课程大纲、最终发布页面

（1）复制页面内容、拷贝到对应页面

Course/chapter.vue

<template>
  <div class="app-container">
    <h2 style="text-align: center;">发布新课程</h2>

    <el-steps :active="2" process-status="wait" align-center style="margin-bottom: 40px;">
      <el-step title="填写课程基本信息"/>
      <el-step title="创建课程大纲"/>
      <el-step title="提交审核"/>
    </el-steps>

    <el-form label-width="120px">
      <el-button type="text" @click="dialogChapterFormVisible = true">添加章节</el-button>
      <!--章节-->
      <ul class="chanpterList">
        <li v-for="chapter in allChapterVideo" :key="chapter.id">
          <p>
            {{ chapter.title }}
            <span class="acts">
              <el-button type="text">添加课时</el-button>
              <el-button style type="text">编辑</el-button>
              <el-button type="text" @click="removeChapter(chapter.id)">删除</el-button>
            </span>
          </p>
          <!--小节（视频）-->
          <ul class="chanpterList videoList">
            <li v-for="video in chapter.children" :key="video.id">
              <p>{{ video.title }}</p>
            </li>
          </ul>
        </li>
      </ul>

      <el-button @click="previous">上一步</el-button>
      <el-button :disabled="saveBtnDisabled" type="primary" @click="next">下一步</el-button>

    </el-form>
    <!-- 添加和修改章节表单 -->
    <el-dialog :visible.sync="dialogChapterFormVisible" title="添加章节">
      <el-form :model="chapter" label-width="120px">
        <el-form-item label="章节标题">
          <el-input v-model="chapter.title"/>
        </el-form-item>
        <el-form-item label="章节排序">
          <el-input-number v-model="chapter.sort" :min="0" controls-position="right"/>
        </el-form-item>
      </el-form>
      <div slot="footer" class="dialog-footer">
        <el-button @click="dialogChapterFormVisible = false">取 消</el-button>
        <el-button type="primary" @click="saveOrUpdate">确 定</el-button>
      </div>
    </el-dialog>
  </div>
</template>

<script>

      chapter.addChapter(this.chapter).then(response => {

        // 提示
        this.$message({

          message: '添加章节成功!'

          })
        })
    },

    // 根据课程id查询章节小节信息
    getChapterVideoList() {
