今天突然想起改良一下以前搭建的“windows service承载的web api”服务，以前也是直接引用的类库，没有使用nuget包，时隔几年应该很旧版本了吧。所以本次把需要nuget获取的包记录一下。
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="log4net" version="2.0.8" targetFramework="net461" />
<package id="Microsoft.AspNet.WebApi.Client" version="5.2.7" targetFramework="net461" />
<package id="Microsoft.AspNet.WebApi.Core" version="5.2.7" targetFramework="net461" />
<package id="Microsoft.AspNet.WebApi.Owin" version="5.2.7" targetFramework="net461" />
<package id="Microsoft.Owin" version="4.0.0" targetFramework="net461" />
<package id="Microsoft.Owin.Host.SystemWeb" version="4.0.0" targetFramework="net461" />
<package id="Microsoft.Owin.Hosting" version="4.0.0" targetFramework="net461" />
<package id="Newtonsoft.Json" version="12.0.1" targetFramework="net461" />
<package id="Owin" version="1.0" targetFramework="net461" />
</packages>
还有几点需要注意一下：
1、设定webapi仅仅使用json格式
using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Net.Http.Formatting;
using System.Net.Http.Headers; namespace NetMiddlewareSvr
{
/// <summary>
/// Json格式头部类
/// </summary>
public class JsonContentNegotiator : IContentNegotiator
{
private readonly JsonMediaTypeFormatter _jsonFormatter; public JsonContentNegotiator(JsonMediaTypeFormatter formatter)
{
_jsonFormatter = formatter;
} public ContentNegotiationResult Negotiate(Type type, HttpRequestMessage request, IEnumerable<MediaTypeFormatter> formatters)
{
var result = new ContentNegotiationResult(_jsonFormatter, new MediaTypeHeaderValue("application/json"));
return result;
}
}
}
2、修改默认路由规则：
using Owin;
using System.Net.Http.Formatting;
using System.Web.Http; namespace NetMiddlewareSvr
{
public class RegisterRoutesStartup
{
public void Configuration(IAppBuilder appBuilder)
{
HttpConfiguration config = new HttpConfiguration();
//自定义路由
config.Routes.MapHttpRoute(
name: "CustomApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
//只响应Json请求
var jsonFormatter = new JsonMediaTypeFormatter();
config.Services.Replace(typeof(IContentNegotiator), new JsonContentNegotiator(jsonFormatter));
appBuilder.UseWebApi(config);
}
}
}
3、启动监听
public partial class NetMiddwareService : ServiceBase
{
private IDisposable hostObject;
public NetMiddwareService()
{
InitializeComponent();
} protected override void OnStart(string[] args)
{
hostObject = hostObject = WebApp.Start<RegisterRoutesStartup>("http://" + "127.0.0.1" + ":5990");
} protected override void OnStop()
{
}
}
补充一下nuget的顺序：Microsoft.Owin->Microsoft.Owin.Hosting->Microsoft.AspNet.WebApi.Core,剩下的是依赖包自动导入的。当然log4net和Newtonsoft.Json不是owin的依赖包
