关于asp.net:asp验证-用于在.net核心上触发

asp-validation-for triggering on get .net core

我有一个.NET Core应用程序，一旦从get返回页面，就会触发验证。我有一个视图模型，我不确定为什么收到响应后就已经触发了验证。

这是我的模型和标记

using System.ComponentModel.DataAnnotations;

namespace MusicianProject.Models.ViewModels
{
public class RegisterViewModel
{
[Required(ErrorMessage ="First name is required.")]
[Display(Name ="First Name")]
[StringLength(25, ErrorMessage ="First name must be less than 25 characters.")]
public string FirstName { get; set; }

[Required(ErrorMessage ="Last name is required")]
[Display(Name ="Last Name")]
[StringLength(50, ErrorMessage ="Last name must be less than 50 characters.")]
public string LastName { get; set; }

[Required]
[EmailAddress]
[Display(Name ="Email")]
public string Email { get; set; }

[Required]
[StringLength(100, ErrorMessage ="The {0} must be at least {2} and at max {1} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name ="Password")]
public string Password { get; set; }

[Required]
[DataType(DataType.Password)]
[Display(Name ="Confirm password")]
[Compare("Password", ErrorMessage ="The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }

}
}

这是返回的寄存器视图。

@model MusicianProject.Models.ViewModels.RegisterViewModel

<form asp-controller="Account" asp-action="Register" method="post">

<label asp-for="FirstName"></label>
<input class="form-control" type="text" asp-for="FirstName" />
<span asp-validation-for="FirstName">First name is required.</span>

<label asp-for="LastName"></label>
<input class="form-control" asp-for="LastName" />
<span asp-validation-for="LastName">Last name is required.</span>

<label asp-for="Email"></label>
<input class="form-control" type="text" asp-for="Email" />
<span asp-validation-for="Email">Email is required.</span>

<label asp-for="Password"></label>
<input asp-for="Password" type="password" id="password" class="form-control" />
<span asp-validation-for="Password">Password is required.</span>

<label asp-for="ConfirmPassword"></label>
<input asp-for="ConfirmPassword" type="password" id="confirm-password" class="form-control" />
<span asp-validation-for="ConfirmPassword">Confirm password is required</span>

<button class="btn btn-default">Sign up!</button>
<button class="btn btn-danger">Cancel</button>

</form>

我有两种注册方法，post和get。这就是我所拥有的。

[HttpGet]
public IActionResult Register()
{
return View();
}

[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult Register(RegisterViewModel rvm)
{
if (ModelState.IsValid)
{

return RedirectToAction("Index","Home");
}

return View();
}

当我在浏览器中导航到该路线时，这就是我得到的。

只需删除视图中<span asp-validation-for>标记内的所有文本。

当出现验证错误时，标签助手将为您注入文本，具体取决于注释的设置。您现在拥有的方式将强制打印这些消息。
