C#webapi的编写 路由重写

namespace web.api.Controllers
{
    //重新定义路由地址
    [RoutePrefix("user")]
    public class UserInfoController : ApiController
    {
        [HttpGet]
        //子路由地址
        [Route("loginin")]
        public string checkLogin(string username, string pwd)
        {
            return userinfoServices.checkUserInfo(username, pwd);
        }
    }
}
