c# - 查询字符串的属性路由

Question

我有以下路由 URL:-

www.domanname.com/subroute/GetInfo?param1=somestring&param2=somestring

我在 webapi 中的功能是:-

public class HomeController : ApiController
{
    public object GetInfo(string param1,string param2)
    {}
}

申请路线:-

[RoutePrefix("subroute")]
public class HomeController : ApiController
{
    [Route("GetInfo?param1={param1:string}&param2={param2:string}")]
    public object GetInfo(string param1,string param2)
    {}
}

但是在应用上面的 URL 之后:-

www.domanname.com/subroute/GetInfo?param1=somestring&param2=somestring

无法找到该 URL

我该如何设计这条特定的路线？

Answer 1

您需要稍微修改一下路由，因为查询字符串通常不用于属性路由。它们往往用于内联路由参数。

[RoutePrefix("subroute")]
public class HomeController : ApiController {
    //Matches GET subroute/GetInfo?param1=somestring&param2=somestring
    [HttpGet]
    [Route("GetInfo")]
    public IHttpActionResult GetInfo(string param1, string param2) {
        //...
    }
}

Enabling Attribute Routing

To enable attribute routing, call MapHttpAttributeRoutes during configuration. This extension method is defined in the System.Web.Http.HttpConfigurationExtensions class.

using System.Web.Http;

namespace WebApplication
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API routes
            config.MapHttpAttributeRoutes();

            // Other Web API configuration not shown.
        }
    }
}
