Vue项目常见的文档导入调接口

<div style="float: right; margin-left: 10px;">
     <upload-file
        text="模板导入" 
        :data="otherData" 
        :url="uploadURL" 
        @success="uploadSuccess"
>
     </upload-file>
 </div>

<template>
  <!--使用说明：
        <upload-file text="导入" :url="uploadUrl" @success="uploadCallback"></upload-file>
        属性
            text:为上传按钮显示的文字,必填
            url:为上传的url地址，必填
            btnQx:权限按钮控制，若不需控制按钮权限，不传即可，有权限按钮控制，值为是否有权限的boolear值
            accept:上传文件类型，默认为excel
            disabled:禁用 默认false
        事件：
            success：上传成功的回调函数，返回后台返回的值
