用户注册需要获取手机号然后调用第三方接口获取验证码，然后进行验证手机验证码

手机号注册页面

<!-- 绑定手机号 -->
<view class='content'>
 <form bindsubmit="formSubmit">
  <view class='phone-box'>
   <text class='phone'>手机号</text>
   <input name="phone" type='number' placeholder="请输入手机号" maxlength='11' name="phone" class='number' bindinput='lovePhone' />
