C# Razor页面将表单数据发布到控制器

我使用WebAPI模板在.NETCore2.2中开发了一个非常简单的web应用程序。我已经能够使用Postman成功地测试我的端点，并且希望使用已经可用的Razor页面（.cshtml）添加一个简单的前端

问题： 我无法使用razor页面成功命中控制器端点。我已尝试使用/不使用“[FromBody]”来装饰端点

我的chrome调试器捕获以下事务：

网页上的错误：

{"type":"https://tools.ietf.org/html/rfc7231#section-6.5.13","title":"Unsupported Media Type","status":415,"traceId":"0HLSP5DVTEH9B:00000008"}

输出表示路由已匹配：

代码：

我有以下页面： 注册。cshtml

@page
@using Microsoft.AspNetCore.Mvc.Rendering
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
@model RegistrationModel
@{
    ViewData["Title"] = "Registration";
}
<h2>@ViewData["Title"]</h2>

@{
    using (Html.BeginForm("Register", "Registration", FormMethod.Post))
    {
        <label>Username</label>
        @Html.TextBoxFor(m => m.Username)

        <br />

        <label>Password</label>
        @Html.TextBoxFor(m => m.Password)

        <br />

        <label>Role</label>
        <label>
            @Html.RadioButtonFor(m => m.Role, "0")
            1
        </label>
        <label>
            @Html.RadioButtonFor(m => m.Role, "1")
            2
        </label>

        <br />

        <input type="submit" value="Register" />
    }
}

控制器：

namespace RandomContent.Controllers
{
    [Authorize]
    [ApiController]
    [Route("Registration")]
    public class RegistrationController : ControllerBase
    {
        private readonly IRegistrationService _registrationService;

        public RegistrationController(IRegistrationService registrationService)
        {
            _registrationService = registrationService;
        }

        /// <summary>
        /// Creates a new user
        /// Will return a bad request if the user could not be added to the db
        /// or the user already exists
        /// </summary>
        /// <param name="userParam"></param>
        /// <param name="returnUrl"></param>
        /// <returns></returns>
        [AllowAnonymous]
        [HttpPost]
        [Route("Register")]
        public IActionResult Register(RegistrationModel userParam)
        {
            //Validations
            if (!Enum.IsDefined(typeof(Role), userParam.Role))
                return BadRequest("Must select valid Role for user");
            if (string.IsNullOrWhiteSpace(userParam.Username))
                return BadRequest("Must enter a username");
            if (string.IsNullOrWhiteSpace(userParam.Password))
                return BadRequest("Must enter a password");

            //Register user
            var user = _registrationService.Register(userParam);
            if (user != null) return Ok(user);
            return BadRequest("Could not create user profile. They username may have been taken, or something else happened.");
        }

    }
}

namespace RandomContent.controller
{
[授权]
[ApiController]
[路线（“注册”）]
公共类注册控制器：ControllerBase
{
私人只读IRegistrationService\u registrationService；
公共注册控制器（IRegistrationService registrationService）
{
_注册服务=注册服务；
}
/// 
///创建一个新用户
///如果无法将用户添加到数据库，则将返回错误的请求
///或者用户已经存在
/// 
/// 
/// 
/// 
[异名]
[HttpPost]
[路线（“登记”）]
公共IActionResult寄存器（RegistrationModel userParam）
{
//验证
如果（！Enum.IsDefined（typeof（Role），userParam.Role））
return BadRequest（“必须为用户选择有效角色”）；
if（string.IsNullOrWhiteSpace（userParam.Username））
返回请求（“必须输入用户名”）；
if（string.IsNullOrWhiteSpace（userParam.Password））
返回请求（“必须输入密码”）；
//注册用户
var user=\u registrationService.Register（userParam）；
如果（user！=null）返回Ok（user）；
return BadRequest（“无法创建用户配置文件。他们的用户名可能已被占用，或者发生了其他事情。”）；
}
}
}

问题：如何将表单数据成功发布到控制器中？我甚至不能调试到我的控制器，除非我从邮递员发送我的请求

可以在Github上找到完整的项目：

尝试使用[FromForm]这样的注册表（[FromForm]RegistrationModel userParam）

这是否回答了您的问题？

namespace RandomContent.Controllers
{
    [Authorize]
    [ApiController]
    [Route("Registration")]
    public class RegistrationController : ControllerBase
    {
        private readonly IRegistrationService _registrationService;

        public RegistrationController(IRegistrationService registrationService)
        {
            _registrationService = registrationService;
        }

        /// <summary>
        /// Creates a new user
        /// Will return a bad request if the user could not be added to the db
        /// or the user already exists
        /// </summary>
        /// <param name="userParam"></param>
        /// <param name="returnUrl"></param>
        /// <returns></returns>
        [AllowAnonymous]
        [HttpPost]
        [Route("Register")]
        public IActionResult Register(RegistrationModel userParam)
        {
            //Validations
            if (!Enum.IsDefined(typeof(Role), userParam.Role))
                return BadRequest("Must select valid Role for user");
            if (string.IsNullOrWhiteSpace(userParam.Username))
                return BadRequest("Must enter a username");
            if (string.IsNullOrWhiteSpace(userParam.Password))
                return BadRequest("Must enter a password");

            //Register user
            var user = _registrationService.Register(userParam);
            if (user != null) return Ok(user);
            return BadRequest("Could not create user profile. They username may have been taken, or something else happened.");
        }

    }
}
