直接通过element-ui自带的上传组件结合js即可，代码如下：

HTML：

<el-upload class="upload-demo" :action="actionUrl" :show-file-list="false" :on-success="handleAvatarSuccess" :before-upload="beforeAvatarUpload"> <button class="ce-button not-hover primary"> <i class="ce-icon_upload"></i> <span>重新上传</span> </button> </el-upload>

js：

beforeAvatarUpload(file) { var fileName = file.name || '' var ext = fileName.split('.')[fileName.split('.').length - 1] if (ext !== "doc" && ext !== "docx" && ext !== "xls" && ext !== "xlsx" && ext !== "ppt" && ext !== "pptx" && ext !== "pdf" && ext !== "mp4") { this.$notify({ title: "失败", message: "上传资源只能是 doc/docx/xls/xlsx/ppt/pptx/pdf/mp4 格式!", type: "error", duration: 3000 }); return false } // ppt(10MB)，word(10MB)，excel(5MB) if (ext == "doc" || ext == "docx" || ext == "ppt" || ext == "pptx") { debugger if (parseInt(file.size) > parseInt('10485760‬')) { this.$notify({ title: "失败", message: "上传word、ppt文件上限为10MB!", type: "error", duration: 3000 }); return false } } if (ext == 'mp4') { // 获取视频时长 var url = URL.createObjectURL(file); var audioElement = new Audio(url); var duration; audioElement.addEventListener("loadedmetadata", function (_event) { duration = audioElement.duration; //时长为秒，小数，182.36 this.$parent.$data.wDuration = parseInt(duration) console.log(duration); }); } this.$parent.$data.wFileName = file.name this.$parent.$data.wSize = parseFloat(file.size / 1024).toFixed(2) //获取文件大小 }

总结
