在App_Start下新建WebApiConfig.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;

namespace NFine.Web
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                //注意此处的路由前缀统一添加了'api/',以便和mvc路由区分,如果不修改,则会导致路由路径一样,只会进入同一个路由导致出错
                routeTemplate: "api/{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }
}

在Controllers文件夹下添加webApi路由 TestController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using Base;
using System.Net.Http.Headers;
using NPOI.HSSF.UserModel;
using NPOI.SS.UserModel;
using System.IO;

namespace NFine.Web.Controllers
{
    public class testController : ApiController
    {
        [HttpGet]
        public HttpResponseMessage test()
        {
            return "hellow world".HttpResponseSerializeObject(true, "");
        }
}

在Global.asax中注册路由

using NFine.Code;
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Routing;

namespace NFine.Web
{
    public class MvcApplication : System.Web.HttpApplication
    {
        /// <summary>
        /// 启动应用程序
        /// </summary>
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            //在此处注册webApi的路由
            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
        }
    }
}

运行程序,然后看能否进入正常网页,并且在浏览器内输入http://localhost:1851/api/test/test,返回{"result":true,"error":"","data":"hellow world"},表示成功!
