最终的项目图，如图所示：

这里只是附加代码和功能；具体需要有一些基础Vue基础的人

一、表单相关的实现

这里采用的是Element组件，为我们方便进行开发

主要设计到的功能如下：
表单的提交和校验、表单的自定义校验，如下如密码的自定义校验，把文件放在自定义模板组件中

<template>
  <div class="page-register">
    <article class="header">
      <header>
        <a href="/" class="site-logo" />
        <span class="login">
          <em class="bold">已有美团账号？</em>
          <a href="/login">
            <el-button type="primary" size="small">登录</el-button>
          </a>
