我可以控制用户授权，包括表单、两个文本框和提交按钮。 此控件通过 RenderAction 方法包含在母版页中。 我有注册页面(它的 View 通过 RenderBody 方法包含)也有表格。当我从注册表单提交数据时，也会触发登录控件并调用其处理程序(用于处理 POST 数据的 Controller 方法)。您可以在下面看到用于授权的 Controller 方法。 从其他表单提交数据后，如何防止向登录控件发送POST数据？
[HttpPost]
public RedirectResult LogIn(AuthViewModel authResult)
{
if (ModelState.IsValid)
{
userService.LogInUser(authResult.Login, authResult.Password, Request.UserHostAddress);
}
else
{
TempData["AuthMessage"] = GetValidationMessage();
}
string redirectUrl = "/";
if (Request.UrlReferrer != null)
{
redirectUrl = Request.UrlReferrer.AbsoluteUri.ToString();
}
return Redirect(redirectUrl);
}
[HttpGet]
[ChildActionOnly]
public PartialViewResult LogIn()
{
if (userService.IsUserLoggedIn())
{
User currentUser = userService.GetLoggedInUser();
ViewBag.LoggedInMessage = currentUser.FullName + "(" + currentUser.Login + ")";
}
return PartialView("AuthControl");
}

注册页面:
RegistrationViewModel

@if (TempData["RegistrationFinished"] == null || !(bool)TempData["RegistrationFinished"])
{
<div class="post content-holder">

@using (Html.BeginForm())

最佳答案
在注册 View 中，更改
@using (Html.BeginForm())
到
@using (Html.BeginForm("Index", "Registration"))
在单个 Controller 、单个 Action 场景中，不需要额外的特定路由信息，但显然路由引擎无法自行确定将多个 Controller /操作路由到哪个 Controller /操作。
根据评论编辑:
所以这是一个路由问题。尝试为您的注册操作添加特定路线。有点像
routes.MapRoute(
"Register", // Route name
"{controller}/Index/{registrationResult}", // URL with parameters
new {
controller = "{controller}",
action = "Selector",
registrationResult= UrlParameter.Optional
}
);
'registrationResult' 将是后操作中的参数名称。我在想 View 模型是如此相似以至于路由引擎无法区分两者。在默认路由之前添加上面的路由，提交注册表时应该匹配。
