如果没有路由,HttpContext.Current.Session
那么我知道它StateServer
正在运行.当我路由我的请求时,HttpContext.Current.Session
是null
在路由页面中.我在IIS 7.0上使用.NET 3.5 sp1,没有MVC预览.似乎AcquireRequestState
在使用路由时从不触发,因此会话变量未实例化/填充.
当我尝试访问Session变量时,我收到此错误:
base {System.Runtime.InteropServices.ExternalException} = {"Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the
在调试时,我也得到了HttpContext.Current.Session
在该上下文中无法访问的错误.

我web.config
看起来像这样:
... ... ... ...
这是IRouteHandler实现:
public class WebPageRouteHandler : IRouteHandler, IRequiresSessionState { public string m_VirtualPath { get; private set; } public bool m_CheckPhysicalUrlAccess { get; set; } public WebPageRouteHandler(string virtualPath) : this(virtualPath, false) { } public WebPageRouteHandler(string virtualPath, bool checkPhysicalUrlAccess) { m_VirtualPath = virtualPath; m_CheckPhysicalUrlAccess = checkPhysicalUrlAccess; } public IHttpHandler GetHttpHandler(RequestContext requestContext) { if (m_CheckPhysicalUrlAccess && !UrlAuthorizationModule.CheckUrlAccessForPrincipal( m_VirtualPath, requestContext.HttpContext.User, requestContext.HttpContext.Request.HttpMethod)) { throw new SecurityException(); } string var = String.Empty; foreach (var value in requestContext.RouteData.Values) { requestContext.HttpContext.Items[value.Key] = value.Value; } Page page = BuildManager.CreateInstanceFromVirtualPath( m_VirtualPath, typeof(Page)) as Page;// IHttpHandler; if (page != null) { return page; } return page; } }
我也试图把它EnableSessionState="True"
放在aspx页面的顶部,但仍然没有.
任何见解?我应该写另一个HttpRequestHandler
实现的IRequiresSessionState
吗?
谢谢.
得到它了.实际上相当愚蠢.我删除并添加了SessionStateModule之后就可以了:
... ... ...
简单地添加它将不起作用,因为"会话"应该已经在中定义machine.config
.
现在,我想知道这是否是通常的事情.它肯定似乎不是这样,因为它看起来如此粗糙......
只需在web.config中添加属性runAllManagedModulesForAllRequests="true"
即可system.webServer\modules
.
默认情况下,此属性在MVC和动态数据项目中启用.
runAllManagedModulesForAllRequests=true
实际上是一个真正的坏解决方案 这使我的应用程序的加载时间增加了200%.更好的解决方案是手动删除和添加会话对象,并避免一起运行所有托管模块属性.
这些解决方案都不适合我。我添加了以下方法,global.asax.cs
然后Session不为空:
protected void Application_PostAuthorizeRequest() { HttpContext.Current.SetSessionStateBehavior(SessionStateBehavior.Required); }
