重定向不包括应用程序名称，并且身份验证无法正常工作

Question

我正在尝试实现“管理员”登录，以便我的用户可以自己添加内容，而我不必担心陌生人会以某种方式路由到“创建/编辑/删除操作”。我将用户名和密码放在Web.config文件中进行身份验证，并且在Visual Studio中一切正常。但是，当我将应用程序发布到IIS时，身份验证似乎失败了，并且当重定向回“登录”操作时，我得到了404 Not Found Error。重定向或返回视图时，路由不包含应用程序名称{application name}/Authentication/Login而是仅返回Authentication/Login，但是当我尝试访问其中一个创建操作时，它将成功重定向，这使我发疯非常感谢您的帮助。

RouteConfig.cs

routes.MapRoute(
                name: "Authentication",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Authentication", action = "Login", id = UrlParameter.Optional }
            );

AuthenticationController.cs

namespace ShipleySwine.Controllers
{
    public class AuthenticationController : Controller
    {
        // GET: Authentication
        public ActionResult Login()
        {
            ViewBag.Message = TempData["Message"];
            return View();
        }

        [HttpPost]
        public ActionResult Login(AuthenticationViewModel vm)
        {
            //if (ModelState.IsValid)
            //{
            //    if (vm.user.userName == System.Configuration.ConfigurationManager.AppSettings["Admin"].ToString() && vm.user.password == System.Configuration.ConfigurationManager.AppSettings["adminPass"].ToString())
            //    {
            //        Session["Authentication"] = "Success";
            //        return RedirectToAction("Index", "Admin");
            //    }
            //    else
            //    {
            //        TempData["Message"] = "Login failed, Incorrect username/password";
            //        return Redirect("/ShipleySwine/Authentication/Login");
            //        //return RedirectToAction("Login", "Authentication");
            //    }
            //}
            //else
            //{
            //    //return RedirectToAction("Login", "Authentication");
            //    return Redirect("/ShipleySwine/Authentication/Login");
            //}

            if (ModelState.IsValid)
            {
                if (vm.user.userName == System.Configuration.ConfigurationManager.AppSettings["Admin"].ToString() && vm.user.password == System.Configuration.ConfigurationManager.AppSettings["adminPass"].ToString())
                {
                    Session["Authentication"] = "Success";
                    return RedirectToAction("Index", "Admin");
                }
                else
                {
                    TempData["Message"] = "Login failed, Incorrect username/password";
                    ViewBag.Message = "Login failed, Incorrect username/password";
                    return View();
                }
            }
            else
            {
                return View();
            }
        }
    }
}

创建操作成功重定向

Answer 1

显然我没有给自己足够的时间...

仔细观察后才知道。我将动作硬编码在Login.cshtml

中

<form action="/Authentication/Login" method="post">

这在Localhost上运行的Visual Studio中很好用，但是当发布到IIS时，该路由不存在。实际上，它不是重定向的，因为表单没有成功传递给控制器​​

更正Login.cshtml

<div class="row">
    <div class="col-4">
    </div>
    <div style="padding: 50px; margin-top: 25px;" class="col-4 backgroundcolor rounded">
        <h2 class="text-center">Login</h2>
        @using (@Html.BeginForm("Login", "Authentication", FormMethod.Post))
        {

            <div class="form-group">
                <label for="exampleInputEmail1">Username</label>
                <input name="user.userName" type="text" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp" placeholder="Enter Username">
            </div>
            <div class="form-group">
                <label for="exampleInputPassword1">Password</label>
                <input name="user.password" type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
            </div>
            if (ViewBag.Message != null)
            {
                <p class="text-danger font-weight-bold">@ViewBag.Message</p>
            }
            <div class="text-center">
                <button type="submit" class="btn btn-primary">Submit</button>
            </div>

        }
    </div>

重要的更改是标记帮助器@using (@Html.BeginForm("Login", "Authentication", FormMethod.Post))

只需将您的表格更改为此：

<form action="@Url.Action("Login")" method="post">
