传递用户信息到MVC控制器 [英] Passing User Info to MVC Controller

问题描述

我在看不同的方法来实现在我MVC3应用验证。我想用我自己的code做认证 - 类似的东西<一个href=\"http://stackoverflow.com/questions/1438151/is-it-possible-to-create-a-logon-system-with-asp-net-mvc-but-not-use-the-members\">Is它可以创建一个登录系统的ASP.NET MVC，但不使用的MembershipProvider？的（我知道还有其他的方法。）的我想知道，一旦我使用验证用户这些方法，我如何获得用户信息传递给控制器​​构造之一。的（用户信息，我的意思是用户名或用户ID）。的

I am looking at various methods to implement Authentication in my MVC3 app. I would like to use my own code to do the authentication – something similar to Is it possible to create a Logon System with ASP.NET MVC but not use the MembershipProvider? (I know that there are other methods.) I would like to know once I authenticate a user using one of these methods, how do I get the user information to the Controller constructor. (By user information I mean username or userID).

一个我认为是把这些信息在会话选项。这工作，但它是很难测试，因为我得到的会话退出的 Context，它在不存在的测试。

One of the options I considered is putting that info into the Session. This works, but it is difficult to test since I get the Session out of the Context which does not exist during the test.

我想AP preciate了如何将用户信息传递给控制器​​构造的任何想法。

I would appreciate any ideas for how to pass user info to the controller constructor.

推荐答案

在我原来的职位我一直在寻找通过用户信息到控制器构造函数。我不想让控制器取决于的HttpContext ，因为这将使它很难测试。

In my original post I was looking at passing User Info to the Controller constructor. I did not want the Controller to depend on HttpContext, because this would make it difficult to test.

虽然我感谢的空军终于曼作为他的解决方案，我希望下面的替代解决方案将帮助别人。我有一个小项目的（大约十几控制器）的，所以它不是太糟糕了。

While I thank Mystere Man for his solution, I hope the following alternate solution would help someone. I have a small project (about a dozen controllers) so it is not too bad.

我基本上创建我的自定义的ControllerFactory 从 DefaultControllerFactory 继承：

I basically created my custom ControllerFactory inheriting from DefaultControllerFactory:

public class MyCustomControllerFactory : DefaultControllerFactory
    {
        public MyCustomControllerFactory ()
        {
        }


        protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
        {
            if (controllerType == null)
            {
                return null;
            }
            else
            {
                //Example of User Info - Customer ID
                string customerIDStr =  requestContext.HttpContext.Session["CustomerID"].ToString();
                int customerID = Int32.Parse(customerIDStr);

                //Now we create each of the Controllers manually
                if (controllerType == typeof(MyFirstController))
                {
                    return new MyFirstController(customerID);
                }
                else if (controllerType == typeof(MySecondController))
                {
                    return new MySecondController(customerID);
                }
                //Add/Create Controllers similarly
                else //For all normal Controllers i.e. with no Arguments
                {
                    return base.GetControllerInstance(requestContext, controllerType);
                }
            }
        }
    }

我然后设置的ControllerFactory 在的Global.asax.cs 的Application_Start（） 方法。

protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            RegisterGlobalFilters(GlobalFilters.Filters);
            RegisterRoutes(RouteTable.Routes);

            ControllerBuilder.Current.SetControllerFactory(new MyCustomControllerFactory ());
        }

P.S。我看着使用DI容器，如Ninject，但我认为他们是为我的当前项目太复杂了。我想看看他们在几个月后当它真正有意义的使用它们。

P.S. I looked into using DI Containers like Ninject, but I think they were too complicated for my current project. I would look at them in a few months when it really makes sense to use them.
