为什么Asp.net MVC4不能使用SQL Server会话状态存储的cookie的(Why As

ALL，这是在Asp.net MVC4应用我的web配置。 我发现，如果我设置cookie的假，一切顺利。 但如果我不想使用的cookie。 然后应用程序不能work.when我调试应用程序，我发现控制器不能接收从视图的任何请求。 我认为，这是因为，在cookie的模式，东西会被之前添加到URL。 如http：/ /本地主机：8119 /（S（3cicpjpagvpunr5he5fnfrj1））/。

Answer 1:

有一个在错误Html.BeginForm()助手（一个不带任何参数）与使用时cookieless="true" 。 生成的URL时，它没有考虑到的会话ID。 因此，而不是：

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

它产生：

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

当你邮寄到/home/index重定向是自动由/(S(kkt0zgbnuaoxad23ew33iod4))由ASP.NET。 一个重定向意味着GET请求=>您的POST操作将永远不会被击中。

作为一种变通方法，你可以写一个自定义Html.BeginForm帮助修复bug：

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())
{
    ...
}

至于BeginForm助手的其他重载而言，他们应该正常工作，并生成包含会话ID采取适当的行动。
