有一个bug，我无法从OnPost方法的html输入中获取“NewUser”数据。

---

然而，这似乎与“Customer”相同，但是“Customer”工作得很好，能够从输入中获取数据。

为了让您的

OnPost

方法捕获html输入参数，您必须将它们包装在

表单

标记中。因此，您的注册页面Html必须如下所示：

  <form method="post">
   <div class="form-group">
      <div class="form-row">
         <div class="col-md-6">

               <label for="firstName">First name</label>
            </div>
         </div>
         <div class="col-md-6">
            <div class="form-label-group">
               <input type="text" name="lastName" class="form-control" placeholder="Last name" required="required" asp-for="Customer.LastName" />
               <label for="lastName">Last name</label>
