如何限制对MVC中特定文件的访问 [英] How to restrict access to a certain file in MVC

问题描述

我正在使用ASP.Net MVC，我想知道如何限制对特定文件的访问.我读过有关使用[授权]的信息，但它适用于控制器和动作.我尝试在web.config中使用它，但极力建议不要这样做，因为当看到多个时，MVC会变得混乱.

I am using ASP.Net MVC, and I was wondering how can I restrict access to a certain file. I read about using [Authorize] but it applies to controllers and actions. I try to use within the web.config but its extremely advise not to do that cause MVC becomes confuse when seeing multiple .

我的文件位于应用程序的库中，例如/MyApp/MyFile.我想做的是，当用户导航到文件时.用户会看到，如果我输入错误，HTTP 401错误或其他内容，请纠正我.

My file is within the base of the application, e.g. /MyApp/MyFile. I would like to do is, when a user navigates to the file. The user will see, correct me if I'm wrong, the HTTP 401 error or something.

推荐答案

为此，将文件粘贴在App_Data下的文件夹中，这将阻止直接访问，然后您需要创建一个控制器来处理对该文件的访问.首先创建一条路线:

In order to do this stick the files in a folder under App_Data which will prevent direct access and then you will need to create a controller to handle access to the file. First create a route:

routes.MapRoute("", "Files/{file}", new { controller = "File", action = "View" });

然后将Authorize属性应用于操作并使用

and then apply the Authorize attribute to the action and use

return File(...);

将文件实际返回给用户.

to actually return the file to the user.
