custom-attributes

问题 In my MVC 5 application, I decorate my controllers as follows: [Authorize] public class Controller { .. However, one requirement I have is to use a token to authorize an action without going to the login screen. ie: http://{website}/Action?token={/* token for this user */} Thus, how can I develop a custom AuthorizeAttribute that accepts a login (default behavior) OR a token (custom, required behavior)? In other words, if I use http://{website}/Action , I would be redirected to the login

问题 I am looking for a way to show/hide WebAPI routes in the Swagger documentation using SwashBuckle in a configurable way. Adding [ApiExplorerSettings(IgnoreApi = true)] will indeed hide the routes but I'd need to recompile every time I want that to change. I have looked into creating an IOperationFilter to work with a custom Attribute that I defined. That way I can decorate the routes with a [SwaggerTag("MobileOnly")] and check the web.config or something to see if the route should be shown.

问题 I am using Knockout-JS to bind properties in my view to my view model. Knockout-JS uses a custom attribute called 'data-bind' that you have to append to controls in which you want to be bound to view model objects. Example: <input type='text' name='first-name' data-bind='value: firstName'/> Notice the 'data-bind' attribute. In my view rendering, I am having trouble rendering a textbox that has this attribute. I am aware the Html.EditorFor, Html.TextBoxFor, and Html.TextBox helpers all take an

问题 I'm tying to collect all Custom Attributes placed over a Property. There are more than one Attributes of the same type assigned to the Property, but when collecting them , the resulting collection only contains the first Attribute of the specific type: The Attribute class [AttributeUsage(System.AttributeTargets.Property, AllowMultiple = true)] public class ConditionAttribute : Attribute{...} Usage: [ConditionAttribute("Test1")] [ConditionAttribute("Test2")] [ConditionAttribute("Test3")]

问题 Is there a way I can create custom method attributes for WCF that allow me to easily decorate a service method with a pre filter much like MVC uses action filters. I plan to use them for authentication and authorization. This is for a RESTful service whose requests are carrying an authentication cookie. I am more interested in how to create the attributes rather than the authentication side of things. Does the HTTP Toolkit offer anything? Thanks 回答1: WCF has great extensibility - in many ways

问题 I have written a custom AuthorizeAttribute which has the following condition in asp.net mvc3 application: public override void OnAuthorization(AuthorizationContext filterContext) { //auth failed, redirect to Sign In if (!filterContext.HttpContext.User.Identity.IsAuthenticated) { filterContext.Result = new HttpUnauthorizedResult(); } } And in my web.config, i have: <authentication mode="Forms"> <forms loginUrl="~/User/SignIn" timeout="2880" /> </authentication> On authentication fail, it

问题 I have the need to put a custom attribute on an anchor which I am constructing using Html.ActionLink() <%: Html.ActionLink("Delete", "Delete", new { id = Model.ID }, new { data-icon = "ui-icon-trash" })%> Using the proper "data-" prefix, as per http://www.w3.org/TR/html5/elements.html#attr-data, I get the following error from Visual Studio. Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access. Since I can't

问题 I was wondering if it was possible to declare An Attribute property that describes a Property so strong typing is required and ideally that intellisense could used to select the property. Class Types works nicely by declaring the member as Type Type But how to get property as a parameter so that "PropName" is not quoted and is strongly typed? So far: The Attibute Class and sample usage looks like [AttributeUsage(AttributeTargets.Property, AllowMultiple = false)] public class MyMeta :

问题 We implement a log information to our database. I will use a Filters (IActionFilter) functionality for it. I wrote the following class: public class ActionFilter: Attribute, IActionFilter { DateTime start; public void OnActionExecuting(ActionExecutingContext context) { start = DateTime.Now; } public void OnActionExecuted(ActionExecutedContext context) { DateTime end = DateTime.Now; double processTime = end.Subtract(start).TotalMilliseconds; ... some log actions } } Then I have added the

问题 well I know from my asp.net mvc experience that you can have attributes that handle exceptions (HandleErrorAttribute). As far as I can tell the Controller class has some OnException event which may be integral to this behaviour. However, I want to do something similar in my own code: dream example: public String MyProperty { [ExceptionBehaviour(typeof(FormatException), MyExEnum.ClearValue)] set { _thing.prop = Convert.ToThing(value); } } .... The code above obviously makes very little sense,
