如何在Firebase和Vue.js中设置电子邮件验证

我正在尝试基于构建Vue.js/Firebase身份验证接口。此代码使用.sendEmailVerification挂钩在注册帐户时触发验证电子邮件。注册时基于电子邮件的验证似乎工作正常。然而，登录似乎也会触发一封验证电子邮件，我认为这是因为代码中的.onAuthStatechanged钩子没有设置为区分注册和登录

基本上，我想将其设置为仅在注册时触发验证电子邮件，而不是在登录时触发。解决这个问题的最佳方法是什么？请参阅下面的代码

<template>
  <div>
    <div class="container">
      <input type="email" id="txtEmail" v-model="authInput.txtEmail" placeholder="Email">
      <input type="Password" id="txtPassword" v-model="authInput.txtPassword" placeholder="Password">
    </div>

    <div class="container">
      <button id="btnLogin" v-on:click="Login()">Log in</button>
      <button id="btnSignUp" v-on:click="SignUp()">Sign Up</button>
      <button id="btnLogout" v-on:click="LogOut()" style="display:none">Log out</button>
    </div>
  </div>
</template>

已解决：

我将Firebase.auth.onAuthStateChanged拆分为两个单独的函数，一个用于触发验证电子邮件，另一个用于在newUser.emailVerified==true时方便登录

这只允许在注册时触发验证电子邮件，从而解决我的上述问题。请随意添加反馈
