.NET Web API如何配置路由（Routing）

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

// 启用 MVC 并添加控制器支持
app.MapControllers(); // 这会启用属性路由

app.Run();

[ApiController]
[Route("api/[controller]")]
public class ProductsController : ControllerBase
{
    [HttpGet] // GET: api/products
    public IActionResult GetAll() => Ok(new[] { "Product1", "Product2" });

    [HttpGet("{id}")] // GET: api/products/5
    public IActionResult GetById(int id) => Ok($"Product {id}");

    [HttpPost] // POST: api/products
    public IActionResult Create([FromBody] string name) => CreatedAtAction(nameof(GetById), new { id = 1 }, name);
}

app.UseRouting();

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

[Route("api/v1/[controller]")]
public class ProductsController : ControllerBase { }

[HttpGet("{id:int}")] // 只匹配整数
public IActionResult GetById(int id)

[HttpGet("products/all")]
[HttpGet("items")]
public IActionResult GetAll() => Ok();
