Asp net core web api routing by method name

ASP.NET is a popular programming language used for developing web applications. One common challenge faced by developers is how to routing in an ASP.NET Core Web API based on the method name. In this article, we will explore different approaches to this problem and examples to illustrate the solutions.

Approach 1: Attribute Routing

One way to handle routing based on the method name is by using attribute routing in ASP.NET Core. Attribute routing allows you to define routes directly on the controller using attributes.


[ApiController]
[Route("api/[controller]")]
public class UserController : ControllerBase
{
    [HttpGet("get-")]
    public IActionResult GetUsers()
    {
        // Logic to retrieve users
        return Ok(users);
    }

    [HttpGet("get-user/{id}")]
    public IActionResult GetUser(int id)
    {
        // Logic to retrieve a specific user
        return Ok(user);
    }
}

In the above example, we have defined two methods in the UserController class: GetUsers and GetUser. The routes for these methods are specified using the HttpGet attribute. The method is mapped to the route “api/user/get-users” and the second method is mapped to the route “api/user/get-user/{id}”.

Approach 2: Convention-based Routing

Another approach to handle routing based on the method name is by using convention-based routing. Convention-based routing allows you to define routes based on conventions rather than attributes.


public class Startup
{
    public void (IServiceCollection services)
    {
        services.AddControllersWithViews();
    }

    public void Configure( app, IWebHostEnvironment env)
    {
        app.UseRouting();

        app.(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "default",
                pattern: "api/{controller}/{action}/{id?}",
                : new { controller = "Home", action = "Index" });
        });
    }
}

In the above example, we have defined a default route pattern in the Configure method of the Startup class. The pattern “api/{controller}/{action}/{id?}” specifies that the controller name, action name, and optional id parameter will be used to determine the route. For example, a request to “api/user/get-users” will be mapped to the GetUsers method in the UserController class.

Conclusion

Handling routing in an ASP.NET Core Web API based on the method name can be achieved using attribute routing or convention-based routing. Attribute routing allows you to define routes directly on the controller methods using attributes, while convention-based routing allows you to define routes based on conventions. Both approaches provide flexibility and can be used based on your specific requirements.

Remember to choose the approach that best suits your project and adhere to the recommended practices for routing in ASP.NET Core.
