来源： 给现有MVC 项目添加 WebAPI – 小y – 博客园
1. 增加一个WebApi Controller, VS 会自动添加相关的引用，主要有System.Web.Http，System.Web.Http.WebHost，System.Net.Http
2. 在App_Start 下创建 WebApiConfig.cs 并注册路由
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web.Http;
namespace Libaray.Web.App_Start
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API 配置和服务
// Web API 路由
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
}
3. 在Global.asax， Application_Start 下添加 WebAPI 配置
using Libaray.Web.App_Start;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Optimization;
using System.Web.Routing;
namespace Libaray.Web
{
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
}
}
4. 在第一步添加的WebApi 中填写相应代码，
using Libaray.Web.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
namespace Libaray.Web.Controllers
{
[RoutePrefix("api/SystemUsers")]
public class SystemUsersController : ApiController
{
[HttpGet, Route("GetUserList")]
public List<UserModel> GetUserModels()
{
UserModelService UserBS = new UserModelService();
return UserBS.FindList(u => u.isActive == true);
}
[HttpGet, Route("GetUser")]
public UserModel GetUserModel(int id = 0)
{
if(id != 0)
{
UserModelService UserBS = new UserModelService();
return UserBS.Find(u => u.Id == id);
}
else
{
return null;
}
}
[HttpPost, Route("Login")]
public bool Login(string loginId,string password)
{
UserModelService UserBS = new UserModelService();
return UserBS.ValidateLoginInfo(loginId, password);
}
}
}
5. Run the application and call the API. Example: http://localhost:49919/api/SystemUsers/GetUserList
