.net webApi

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

namespace MvcApi.Controllers
{
public class ProductController : ApiController
{
public class User
{
public string name { set; get; }
}

public Dictionary<string, object> GetList(string id)
{
Dictionary<string, object> list = new Dictionary<string, object>();
list.Add("id",id);
return list;
}

public Dictionary<string, object> PostList2(User name)
{
Dictionary<string, object> list = new Dictionary<string, object>();
list.Add("name",name.name);
return list;
}
}
}

方法名以post开头的接收POST请求，Get开头的接收GET请求，默认GET;

接收post请求的方法参数必须是实体类：

public class User
{
public string name { set; get; }
}

访问URI:http://localhost:15172/api/Product/PostList2

namespace MvcApi
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
}

默认返回格式是XML,返回json格式需要在Global.asax.cs里添加：

GlobalConfiguration.Configuration.Formatters.XmlFormatter.SupportedMediaTypes.Clear();
