ASP.NET Web API 不需要 IIS,直接使用控制台程序可以实现。
一、创建一个新的控制台程序,项目名为 HostApi
二、设置目标框架为.NET Framework 4
三、NuGet添加引用 Microsoft.AspNet.WebApi.SelfHost
四、添加一个 Product Model类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; namespace HostApi
{
public class Product
{
public int Id { get; set; }
public string Name { get; set; }
public string Category { get; set; }
public decimal Price { get; set; }
}
}
五、添加一个名为ProductsController
的公共类。从System.Web.Http.ApiController派生此类.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Web.Http; namespace HostApi
{
public class ProductsController : ApiController
{
Product[] products = new Product[]
{
new Product { Id = , Name = "Tomato Soup", Category = "Groceries", Price = },
new Product { Id = , Name = "Yo-yo", Category = "Toys", Price = 3.75M },
new Product { Id = , Name = "Hammer", Category = "Hardware", Price = 16.99M }
}; public IEnumerable<Product> GetAllProducts()
{
return products;
} public Product GetProductById(int id)
{
var product = products.FirstOrDefault((p) => p.Id == id);
if (product == null)
{
throw new HttpResponseException(HttpStatusCode.NotFound);
}
return product;
} public IEnumerable<Product> GetProductsByCategory(string category)
{
return products.Where(p => string.Equals(p.Category, category,
StringComparison.OrdinalIgnoreCase));
}
}
}
六、 托管 Web API
打开 Program.cs 文件,并添加以下使用语句:
using System.Web.Http;
using System.Web.Http.SelfHost;
七、修改Main方法
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; using System.Web.Http;
using System.Web.Http.SelfHost; namespace HostApi
{
class Program
{
static void Main(string[] args)
{
var config = new HttpSelfHostConfiguration("http://localhost:1234"); config.Routes.MapHttpRoute(
"API Default", "api/{controller}/{id}",
new { id = RouteParameter.Optional }); using (HttpSelfHostServer server = new HttpSelfHostServer(config))
{
server.OpenAsync().Wait();
Console.WriteLine("Press Enter to quit.");
Console.ReadLine();
}
}
}
}
直接F5运行,然后打开浏览器访问:
获取所有数据 http://localhost:1234/api/products
获取内码为1的数据 http://localhost:1234/api/products/1
查询category=的数据 http://localhost:1234/api/products?category=Groceries
