Knockout.js validation using extenders - prevent validation on load

阅读更多关于 Knockout.js validation using extenders - prevent validation on load

问题 I have implemented a very basic required validation on "first name" largely based on the example suggested on knockout website (http://knockoutjs.com/documentation/extenders.html) - Live example 2: Adding validation to an observable. My problem is that I don't want the validation to fire when the form is first loaded. Below is my code <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Test</title> <link href="Style.css" rel="stylesheet" /> </head> <body> <p data-bind=

How do I set the WWW-Authentication header in an IAuthenticationFilter implementation?

阅读更多关于 How do I set the WWW-Authentication header in an IAuthenticationFilter implementation?

问题 I'm implementing basic authentication using MVC5's IAuthenticationFilter interface. My understanding is that this is now the preferred approach instead of using a DelegatingHandler. I've got it working but the www-authenticate header is not being returned in the response. This is my implementation of ChallengeAsync: public async Task ChallengeAsync(HttpAuthenticationChallengeContext context, CancellationToken cancellationToken) { var result = await context.Result.ExecuteAsync

How To Deploy Angular And .NET Core Web API On IIS?

阅读更多关于 How To Deploy Angular And .NET Core Web API On IIS?

问题 We have two web sites on IIS for both angular_client and web_api, the hosting bundle is installed and the permission to users such as IUSR, Network, Network Service and Everyone, is already granted. The navigation to each site seperately works, i.e in the API, the call http://localhost:51975/api/user, results in list of all users. The problem is that Angular login page fails to communicate with the API to authenticate users: OPTIONS http://localhost:51975/api/user/authenticate net::ERR

Problems with Model binding and validation attributes with asp.net Web API

阅读更多关于 Problems with Model binding and validation attributes with asp.net Web API

问题 I am writing a Web API with ASP.NET Web API, and make use of the following View Model. I seem to be having a problem with the data binding when there are two validation attributes on a particular property (i.e. [Required] and [StringLength(10)]). When posting a JSON value from a client to a controller action of the form: // POST api/list public void Post([FromBody] TaskViewModel taskVM) I observe the following: If I remove one of the multiple attributes everything is bound OK; If I leave in

阅读更多关于 WebApi OData v4 ComlexType cannot have an EntityType

问题 We were using WebApi OData v 3 and had a couple ComplexType entities defined in the entity data model that contained EntitySet entities. When moving to OData v 4 and upon doing the modelBulder.GetEdmModel() step we get an InvalidOperationException "The complex type 'Foo' refers to the entity 'Bar' through the property 'Bar'." I look at the spec and see a thing called an "abstract entity type" that is a type that holds entity types. I don't see that in the WebApi OData code so I hope that all

Inject IOwinContext with Web API and Ninject

阅读更多关于 Inject IOwinContext with Web API and Ninject

问题 Using Web API 2 and OWIN hosting with Ninject. I would like to inject the current IOwinContext into certain services (so I can get at the Request to get the principal to do some data filtering). With Web Hosting I would, in the old days, simply have used HttpContext.Current but that is not an option with OWIN hosting (and good riddance). This SO question explains how to do it with Autofac. Essentially, you create a Dependency Scope and then, on each request, calls Autofac's Registerinstance
