Routing to an ApiController in a razor page app?

Routing to an ApiController in a razor page app?

In an ASP.NET Core Razor Pages application, you can also create and use API controllers to handle API requests. To do this, follow these steps:

  • Create a new folder named Controllers (if it doesn't already exist) in your Razor Pages project to store your API controllers.

  • Create a new class in the Controllers folder that inherits from ControllerBase and add the [ApiController] attribute to it. Also, specify a route using the [Route] attribute.

using Microsoft.AspNetCore.Mvc; [ApiController] [Route("api/[controller]")] public class MyApiController : ControllerBase { [HttpGet] public IActionResult Get() { return Ok("Hello from the API controller!"); } }

In this example, replace MyApiController with your desired controller name. This API controller has a simple Get action method that returns a message.

  • Update the ConfigureServices method in your Startup.cs file to include both MVC and Razor Pages services:
public void ConfigureServices(IServiceCollection services) { services.AddRazorPages(); services.AddControllers(); // Add this line }
  • Update the Configure method in your Startup.cs file to include routing for your API controllers:
public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { // ... app.UseRouting(); app.UseAuthorization(); app.UseEndpoints(endpoints => { endpoints.MapControllers(); // Add this line endpoints.MapRazorPages(); }); }

Now, your Razor Pages application will route requests to your API controller. In this example, you can access the API controller by making a GET request to the /api/MyApi endpoint (replace MyApi with the actual controller name).

In summary, to add an API controller to your Razor Pages application, create a new controller class that inherits from ControllerBase, add the [ApiController] attribute, and specify a route using the [Route] attribute. Then, update your Startup.cs file to include MVC services and routing for API controllers.
