c# - 从 HTTPModule 访问 session 变量

Question

如何从 HttpModule 访问 session 变量？

我在 .cs 页面中设置了以下 session 变量，我想在 HttpModule 中访问它:

Session["username"] = "BLAH"

我建议采用侵入性较小的方法。只需使用 SetSessionStateBehavior() 强制 ASP.NET 运行时向您的模块公开 session (IRequiresSessionState 的实现仅考虑用于 IHttpHandlers)。

public void Init(HttpApplication httpApp)
{
   //SESSION WILL BE AVAILABLE IN ALL EVENTS FROM PreRequestHandlerExecute TO PostRequestHandlerExecute
   httpApp.PostRequestHandlerExecute += OnPostRequestHandlerExecute;
   //THIS IS THE IMPORTANT LINE
   httpApp.Context.SetSessionStateBehavior(SessionStateBehavior.ReadOnly);
}
