阅读更多关于 Enable CORS for Web Api 2 and OWIN token authentication

I have an ASP.NET MVC 5 webproject (localhost:81) that calls functions from my WebApi 2 project (localhost:82) using Knockoutjs, to make the communication between the two projects I enable CORS. Everything works so far until I tried to implement OWIN token authentication to the WebApi. To use the /token endpoint on the WebApi, I also need to enable CORS on the endpoint but after hours of trying and searching for solutions it is still now working and the api/token still results in: XMLHttpRequest cannot load http://localhost:82/token. No 'Access-Control-Allow-Origin' header is present on the

阅读更多关于 MVC5, WebAPI2 and Ninject Parameterless constructor error

So I have the exact opposite problem as MVC5, Web API 2 and Ninject I have a new MVC5/WebAPI2 project, that has both "Controller"s and "ApiControllers". I'm using the latest unstable version of Ninject.Web.WebAPI with no code changes to NinjectDependencyResolve.cs and Ninject.WebCommom.cs (besides binding my dependency) the ApiController's constructor injection works. However, when I call a MVC Controller I get: No parameterless constructor defined for this object. Tim The issue is you need a Dependency Resolver for both MVC and WebAPI.

Upload file using PUT verb in ASP.Net Web Api 2

阅读更多关于 Upload file using PUT verb in ASP.Net Web Api 2

问题 I would like to expose an ASP.Net Web Api 2 action using the HTTP PUT verb to upload files. This is coherent with our REST model as the API represents a remote file system (similar to WebDAV, but really simplified), so the client chooses the resource names (thus PUT is ideal and POST is not a logical choice). The Web Api documentation describes how to upload files using multipart/form-data forms, but does not describe how to do it using PUT methods. What would you use to test such an API

阅读更多关于 Returning generated CSS from an MVC5 or Web API 2 controller action

In our multi-tenant application we have a need to customize the styles used per-tenant. We currently plan to do so using LESS and variables in the following way on the client : Download dependent LESS files from server Call web service to get configuration object Form string of valid LESS with variables defined Use less.js compiler to compile LESS based on these variables and the fixed LESS files from step 1 This approach has a number of downsides: Clients can behave badly Some browsers have problems with less.js Compilation takes time We would instead like to take care of this work on the

问题 I currently have a Web API that implements a RESTFul API.
