循环数组生成的表单校验 prop需要用原数组加序号的方式来访问，否则会报：  
please transfer a valid prop path to form item!

正确的prop写法： :prop="'courseResourceList.' + index + '.chapterTitle'"  
错误的prop写法： :prop="item.chapterTitle" 或 prop="chapterTitle"

form表单数据结构如下：

<div>
            <el-form :model="courseResourceForm" ref="courseResourceForm" label-position="right" label-width="120px">
              <el-row style="margin-bottom: 10px;">
                <el-col :span="24">上传课程资源</el-col>
              </el-row>
              <div v-for="(item, index) in courseResourceForm.courseResourceList" v-bind:key="item.courseResourceId" class="cardContainer">
                <el-form-item :label="item.chapterId">
                  <upload-file :objAtmParams="item.videoParams" @onSuccess="uploadSuccess" @onRemove="afterDelete"></upload-file>
                </el-form-item>
                <el-form-item label="章节主题" :prop="'courseResourceList.' + index + '.chapterTitle'" :rules="{ required: true, message: '章节主题不能为空', trigger: 'blur' }">
                  <el-input v-model="item.chapterTitle" style="width: 850px"></el-input>
                </el-form-item>
              </div>
            </el-form>
          </div>
    
      data () {
        return {
          courseId: '',
          courseResourceForm: {
            courseResourceList: [{
              chapterId: '',
              chapterTitle: '',
              videoParams: {
                atmLimit: 99, // 上传数量限制
                atmAccepts: '.mp4,.ppt,.pptx,.doc,.docx,.pdf', // 限制上传附件类型
                atmSize: 100,
                atmJobTypeCode: 'bsi_course_learn_video',
                objectId: '',
                fileList: [],
                listType: 'text' // 上传文件样式类型
              }
            }]
          }
        };
      }
