ASP.NET MVC：我在哪里可以获得示例 MVC 项目？ [关闭]

Question

我正在尝试在 MVC 中使用 ActionFilterAttribute 实现身份验证，我正在寻找一些已完成此类身份验证的示例 mvc 项目？

Answer 1

试试 MVC 示例页面，他们提供的身份验证示例应该是您所追求的。

动作过滤器本身并不多，具体的身份验证将取决于您没有详细说明的要求：

/// <summary>
/// Custom authorization attribute for use on controllers and actions. 
/// Throws an exception if the user is not authorized.
/// </summary>
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)]
public sealed class ActionPermissionAttribute : AuthorizeAttribute
{
    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        // Override OnAuthorization, not AuthorizeCore as AuthorizeCore will force user login prompt rather than inform the user of the issue.

        var controller = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName;
        var action = filterContext.ActionDescriptor.ActionName;
        var user = HttpContext.Current.Request.LogonUserIdentity;

        // Check user can use the app or the specific controller/action
        var authorised = ...

        if (!authorised)
            throw new UnauthorizedAccessException("You are not authorised to perform this action.");

        base.OnAuthorization(filterContext);
    }
}
