我有一个具有多个选项卡的应用程序来提交表单。但是，用户在单击“提交”后将获得一个空白表格，并且不会重定向到确认页面。这很奇怪，因为有些应用程序提交得很好，而另一些应用程序没有将字段中的数据存储到数据库中。我的第一个猜测是这是防火墙问题。我正在使用发布方式提交。另外请注意，这是在生产服务器上发生的，而不是在本地开发环境上发生的。

控制器：

        [HttpPost]
        [ValidateAntiForgeryToken]
        [Authorize(Roles = "Applicant")]
        public IactionResult Application(ApplicationViewModel model)
        {

            var saved = false;
            model = _applicantManager.RebuildApplicationViewModel(model);



            if (ModelState.IsValid)
            {
                saved = _applicantManager.SubmitApplication(model,CurrentUser.username);

                return RedirectToaction("Index");
            }


            return View(model);
        }

表格（相当大，为简单起见已缩短）：

 @Html.ValidationSummary(excludePropertyErrors: false,message: "",htmlAttributes: new { @style = "color:red" })

        <ul class="wdn_tabs">
            <li><a href="#personalTab" class="inactiveLink">Personal</a></li>
            <li><a href="#academicTab" class="inactiveLink">Academic</a></li>
            <li><a href="#questionsTab" class="inactiveLink">Questions</a></li>
            <li><a href="#availabilityTab" class="inactiveLink">Availability &amp; Reference</a></li>
        </ul>
        @using (html.beginform(actionName: "Application",controllerName: "Applicant",method: FormMethod.Post))
        {
            @Html.AntiForgeryToken()
            <div class="wdn_tabs_content">
                <div id="personalTab">

                    <div class="tabBody">
