用bootstrap框架后台登陆生成vue2格式template这种的代码无需任何文字说明只要源码即可

<template>
  <div class="login">
    <form class="login-form">
      <h2 class="form-title">Login</h2>
      <div class="form-group">
        <label for="username">Username</label>
        <input type="text" id="username" class="form-control" v-model="username" placeholder="Enter your username">
      </div>
      <div class="form-group">
        <label for="password">Password</label>
        <input type="password" id="password" class="form-control" v-model="password" placeholder="Enter your password">
      </div>
      <div class="form-group">
        <button type="submit" class="btn btn-primary btn-block" @click.prevent="login">Login</button>
      </div>
    </form>
  </div>
</template>
<script>
