阅读更多关于 WebAPI controller inheritance and attribute routing

I have few controllers that inherit from the same base class. Among the different actions that they don't share with each other, they do have a few that are completely identical. I would like to have these on my base class because they all work completely the same it's just that they're accessed through different routes. How should I define these actions with several different routes? My inherited classes also have a RoutePrefixAttribute set on them so each of them is pointing to a different route. Example I have base abstract class called Vehicle and then inherited Car , Bike , Bus etc. All

How do you properly create a Web API POST of complex object or multiple parameters using Angular2? I have a service component in Angular2 as seen below: public signin(inputEmail: string, inputPassword: string): Observable<Response> { return this.http.post('/api/account/signin', JSON.stringify({ Email: inputEmail, Password: inputPassword}), this.options); } The targeted web api is seen below: [HttpPost] [Route("signin")] public async Task<IActionResult> Signin(string email, string password) { .... } This does not work because I need to convert the parameters of the web api into a single POCO

阅读更多关于 AspNet Identity 2: Customize OAuth endpoint response

问题 I successfully implemented my custom OAuthAuthorizationServerProvider . But when I log in and retrieve a token, my client doesn't have any idea of the user's roles, claims, etc. I currently added a webapi controller to return the list of the principal's claims, but I'm not really happy with that. When requesting a token, the current response looks like: { access_token: "qefelgrebjhzefilrgo4583535", token_type: "bearer", expires_in: 59 } Q> How can make it return something like the following

I need to create a Web API C# application for an existing MySQL database. I've managed to use Entity Framework 6 to bind every database table to a RESTful API (that allows CRUD operations) . I want to implement a login/registration system (so that I can implement roles and permissions in the future, and restrict certain API requests) . The MySQL database I have to use has a table for users (called user ) that has the following self-explanatory columns: id email username password_hash It seems that the de-facto standard for authentication is ASP.Net Identity.
