【问题描述】：

所有，这是我在 Asp.net MVC4 应用程序中的网络配置。我发现如果我设置 cookieless false ，一切都很好。但如果我不想使用 cookie 。然后应用程序无法工作。当我调试应用程序时，我发现控制器无法接收来自视图的任何请求。我认为这是因为在无 cookie 模式下，Something 会附加到 url before 。比如 http://localhost:8119/(S(3cicpjpagvpunr5he5fnfrj1))/.

【参考方案1】：

与cookieless="true" 一起使用时，Html.BeginForm() 助手（不带任何参数的助手）中有一个错误。生成 url 时不考虑会话 id。所以而不是：

<form action="/(S(kkt0zgbnuaoxad23ew33iod4))/home/index" method="post">

它生成：

<form action="/home/index" method="post">

当您发布到 /home/index 时，ASP.NET 会自动重定向到 /(S(kkt0zgbnuaoxad23ew33iod4))。重定向意味着 GET 请求 => 您的 POST 操作将永远不会被命中。

作为一种解决方法，您可以编写自定义 Html.BeginForm 帮助程序来修复错误：

public static class FormExtensions

    public static IDisposable MyBeginForm(this HtmlHelper htmlHelper)
    
        var rawUrl = htmlHelper.ViewContext.HttpContext.Request.RawUrl;
        var formAction = htmlHelper.ViewContext.HttpContext.Response.ApplyAppPathModifier("~/") + rawUrl;
        var builder = new TagBuilder("form");
        builder.MergeAttributes(new RouteValueDictionary());
        builder.MergeAttribute("action", formAction);
        builder.MergeAttribute("method", HtmlHelper.GetFormMethodString(FormMethod.Post), true);
        htmlHelper.ViewContext.Writer.Write(builder.ToString(TagRenderMode.StartTag));
        var form = new MvcForm(htmlHelper.ViewContext);
        return form;
    

然后使用：

@using (Html.MyBeginForm())

    ...

就 BeginForm 助手的其他重载而言，它们应该可以正常工作并生成包含会话 ID 的正确操作。
