MVC 3 - 仅限特定用户访问

Question

在我的Web应用程序中,注册用户可以添加新内容并在以后进行编辑.我只希望内容的作者能够编辑它.除了在检查记录的用户是否与作者相同的所有操作方法中手动编写代码之外,还有其他智能方法吗？我可以用于整个控制器的任何属性？

我可以用于整个控制器的任何属性？

是的,您可以Authorize使用自定义属性扩展属性:

public class AuthorizeAuthorAttribute : AuthorizeAttribute
{
    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        var isAuthorized = base.AuthorizeCore(httpContext);
        if (!isAuthorized)
        {
            // the user is either not authenticated or
            // not in roles => no need to continue any further
            return false;
        }

        // get the currently logged on user
        var username = httpContext.User.Identity.Name;

        // get the id of the article that he is trying to manipulate
        // from the route data (this assumes that the id is passed as a route
        // data parameter: /foo/edit/123). If this is not the case and you 
        // are using query string parameters you could fetch the id using the Request
        var id = httpContext.Request.RequestContext.RouteData.Values["id"] as string;

        // Now that we have the current user and the id of the article he
        // is trying to manipualte all that's left is go ahead and look in 
        // our database to see if this user is the owner of the article
        return IsUserOwnerOfArticle(username, id);
    }

    private bool IsUserOwnerOfArticle(string username, string articleId)
    {
        throw new NotImplementedException();
    }
}

然后:

[HttpPost]
[AuthorizeAuthor]
public ActionResult Edit(int id)
{
    ... perform the edit
}
