图像调整User.Identity在事件处理程序 [英] Image Resizer User.Identity in eventhandler

问题描述

增加了一个AuthorizeImage事件处理程序，以图像访问限制。注意到，当我试图检查用户名和authenticationstatus以下内容：

Added an AuthorizeImage eventhandler to image access restriction. Noticed the following when i was trying to check the users name and authenticationstatus:

下面将不会导致异常，但似乎打破它。没有找到图片的默认图标显示，无论认证与否。
经测试this.User =相同的结果。 HttpContext.Current.User =相同的结果。

Below will not result in exception, but seem to break it. Default icon for image not found is displayed no matter authenticated or not. Tested this.User = same result. HttpContext.Current.User = same result

Config.Current.Pipeline.AuthorizeImage += delegate(IHttpModule sender, HttpContext context, IUrlAuthorizationEventArgs e)
{
    if (context.User.Identity.IsAuthenticated) { context.Response.Redirect("http://db2.stb00.s-msn.com/i/AF/263B63C5E656379CEE93E7A8692EC7.gif"); }    
};

下面的工作就好了（this.User和HttpCOntext.Current.User以及）

The below work just fine(this.User and HttpCOntext.Current.User as well)

Config.Current.Pipeline.AuthorizeImage += delegate(IHttpModule sender, HttpContext context, IUrlAuthorizationEventArgs e)
{
    context.Response.Redirect("http://db2.stb00.s-msn.com/i/AF/263B63C5E656379CEE93E7A8692EC7.gif"); 
};

这总是重定向

Config.Current.Pipeline.AuthorizeImage += delegate(IHttpModule sender, HttpContext context, IUrlAuthorizationEventArgs e)
{
    if (context.User == null)
        context.Response.Redirect("http://db2.stb00.s-msn.com/i/AF/263B63C5E656379CEE93E7A8692EC7.gif");
};

我在开始测试的Application_Start但实际上试图Application_PostAuthenticateRequest为好。尽管结果，其中相同的。通过自定义code，但使用标准formsatuhentication设置cookie进出口认证。 [授权]在应用程序工作正常。任何建议什么可以去错在这里？

I started testing in Application_Start but actually tried Application_PostAuthenticateRequest as well. Though the result where the same. Im authenticating via custom code but using standard formsatuhentication to set the cookie. [Authorize] works fine in the application. Any suggestion to what could have gone wrong here?

推荐答案

您的服务器被配置为只运行了一定的要求扩展，如的.aspx，.ashx的，等FormsAuthenticationModule有两种方法来解决这个问题。

Your server is configured to only run the FormsAuthenticationModule for certain request extensions, such as .aspx, .ashx, etc. There are two ways to solve this.

1. 删除并重新添加FormsAuthenticationModule ＆LT; system.webServer＆GT;
＆LT;模块＆gt; （综合模式），丢弃precondition =managedHandler属性：


2. 启用RAMMFAR（runAllManagedModulesForAllRequests）

1. Remove and re-add the FormsAuthenticationModule in <system.webServer> <modules> (For Integrated Mode), dropping the precondition="managedHandler" attribute:
2. Enable RAMMFAR (runAllManagedModulesForAllRequests)
