利用SelfHost实现小型HTTP服务器

1.创建应用,可以是Winform,WPF或者控制台的应用
创建控制台项目
创建控制台应用

2.从Nuget添加下列引用
(1) Microsoft.AspNet.Cors
(2) Microsoft.AspNet.WebApi.Core

(3) Microsoft.Owin

(4) Newtonsoft.Json
(5) Microsoft.AspNet.WebApi.Owin

(6) Microsoft.AspNet.WebApi.Cors
(7) Microsoft.AspNet.WebApi.WebHost
(8) Microsoft.AspNet.WebApi.SelfHost

(9) Microsoft.Owin.Host.HttpListener

(10) Microsoft.Owin.Hosting
安装这些包时,其依赖项也一并安装.
安装依赖库
安装依赖库
依赖库安装完毕后
依赖库安装完毕后

安装完毕后,package.config内容如下:

<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="Microsoft.AspNet.Cors" version="5.2.6" targetFramework="net452" />
<package id="Microsoft.AspNet.WebApi.Client" version="5.2.6" targetFramework="net452" />
<package id="Microsoft.AspNet.WebApi.Core" version="5.2.6" targetFramework="net452" />
<package id="Microsoft.AspNet.WebApi.Cors" version="5.2.6" targetFramework="net452" />
<package id="Microsoft.AspNet.WebApi.Owin" version="5.2.6" targetFramework="net452" />
<package id="Microsoft.AspNet.WebApi.SelfHost" version="5.2.6" targetFramework="net452" />
<package id="Microsoft.AspNet.WebApi.WebHost" version="5.2.6" targetFramework="net452" />
<package id="Microsoft.Owin" version="4.0.0" targetFramework="net452" />
<package id="Microsoft.Owin.Host.HttpListener" version="4.0.0" targetFramework="net452" />
<package id="Microsoft.Owin.Hosting" version="4.0.0" targetFramework="net452" />
<package id="Newtonsoft.Json" version="11.0.2" targetFramework="net452" />
<package id="Owin" version="1.0" targetFramework="net452" />
</packages>

3.接下来,在项目中创建目录WebApi

4.在WebApi下创建目录controllers

5.在WebApi下新建类Startup,内容如下:

using Microsoft.Owin;
using Owin;
using System;
using System.IO;
using System.Net.Http.Formatting;
using System.Threading.Tasks;
using System.Web.Http;
using System.Web.Http.Cors;

namespace HttpSelfHost.WebApi
{

class Startup
{
private static string _siteDir =
System.Configuration.ConfigurationManager.AppSettings.Get("SiteDir");
public void Configuration(IAppBuilder app)
{
// web api 接口
HttpConfiguration config = InitWebApiConfig();
app.UseWebApi(config);
//静态文件
app.Use((context, fun) =>
{
return StaticWebFileHandel(context, fun);
});
}
/// <summary>
/// 路由初始化
/// </summary>
public HttpConfiguration InitWebApiConfig()
{
HttpConfiguration config = new HttpConfiguration();
config.Routes.MapHttpRoute(
name: "Default",
routeTemplate: "api/{controller}/{action}",
defaults: new { id = RouteParameter.Optional }
);
// 配置 http 服务的路由
var cors = new EnableCorsAttribute("*", "*", "*");//跨域允许设置
config.EnableCors(cors);

config.Formatters
.XmlFormatter.SupportedMediaTypes.Clear();
//默认返回 json
config.Formatters
.JsonFormatter.MediaTypeMappings.Add(
new QueryStringMapping("datatype", "json", "application/json"));
//返回格式选择
config.Formatters
.XmlFormatter.MediaTypeMappings.Add(
new QueryStringMapping("datatype", "xml", "application/xml"));

//json 序列化设置
config.Formatters
.JsonFormatter.SerializerSettings = new
Newtonsoft.Json.JsonSerializerSettings()
{
//NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore,
DateFormatString = "yyyy-MM-dd HH:mm:ss" //设置时间日期格式化
};
return config;
}
/// <summary>
/// 客户端请求静态文件处理
/// </summary>
/// <param name="context"></param>
/// <param name="next"></param>
/// <returns></returns>
public Task StaticWebFileHandel(IOwinContext context, Func<Task> next)
{
//获取物理文件路径
var path = GetFilePath(context.Request.Path.Value);
//验证路径是否存在
if (!File.Exists(path) && !path.EndsWith("html"))
{
path += ".html";
}
if (File.Exists(path))
{
return SetResponse(context, path);
}
//不存在返回下一个请求
return next();
}
public static string GetFilePath(string relPath)
{
if (relPath.IndexOf("index") > -1)
{
String temp = relPath;
}
var basePath = AppDomain.CurrentDomain.BaseDirectory;
var filePath = relPath.TrimStart('/').Replace('/', '\\');
if (_siteDir == ".")
{
return Path.Combine(basePath, filePath);
}
else
{
return Path.Combine(
AppDomain.CurrentDomain.BaseDirectory
, _siteDir == "." ? "" : _siteDir
, relPath.Replace('/', '\\')).TrimStart('\\');
}
}

public Task SetResponse(IOwinContext context, string path)
{
/*
.txt text/plain
RTF文本 .rtf application/rtf
PDF文档 .pdf application/pdf
Microsoft Word文件 .word application/msword
PNG图像 .png image/png
GIF图形 .gif image/gif
JPEG图形 .jpeg,.jpg image/jpeg
au声音文件 .au audio/basic
MIDI音乐文件 mid,.midi audio/midi,audio/x-midi
RealAudio音乐文件 .ra, .ram audio/x-pn-realaudio
MPEG文件 .mpg,.mpeg video/mpeg
AVI文件 .avi video/x-msvideo
GZIP文件 .gz application/x-gzip
TAR文件 .tar application/x-tar
任意的二进制数据 application/octet-stream
*/
var perfix = Path.GetExtension(path);
if (perfix == ".html")
context.Response.ContentType = "text/html; charset=utf-8";
else if (perfix == ".txt")
context.Response.ContentType = "text/plain";
else if (perfix == ".js")
context.Response.ContentType = "application/x-javascript";
else if (perfix == ".css")
context.Response.ContentType = "text/css";
else
{
if (perfix == ".jpeg" || perfix == ".jpg")
context.Response.ContentType = "image/jpeg";
else if (perfix == ".gif")
context.Response.ContentType = "image/gif";
else if (perfix == ".png")
context.Response.ContentType = "image/png";
else if (perfix == ".svg")
context.Response.ContentType = "image/svg+xml";
else if (perfix == ".woff")
context.Response.ContentType = "application/font-woff";
else if (perfix == ".woff2")
context.Response.ContentType = "application/font-woff2";
else if (perfix == ".ttf")
context.Response.ContentType = "application/octet-stream";

return context.Response.WriteAsync(File.ReadAllBytes(path));
}
//truetype
return context.Response.WriteAsync(File.ReadAllText(path));
}
}
}

这里需要添加引用:System.Configuration:
添加System.Configuration引用
添加System.Configuration引用

5.在WebApi下新建类WebServer,内容如下:

using System;
using Microsoft.Owin.Hosting;

namespace HttpSelfHost.WebApi
{
public class WebServer
{
static IDisposable server = null;
public static event EventHandles.MessageEventHandle MessageEvent = null;
public static void Start()
{
StartOptions opt = new StartOptions();
opt.Port = int.Parse(System.Configuration.ConfigurationManager.AppSettings.Get("Port"));
string baseAddress = string.Format("http://{0}:{1}/",
"*",
System.Configuration.ConfigurationManager.AppSettings.Get("Port"));
server = WebApp.Start<Startup>(url: baseAddress);
MessageEvent?.Invoke(String.Format("host 已启动：{0}", baseAddress));
}
}
}

6. App.config中添加配置节

其中的port为HttpSelfHost监听的端口
App.config内容
App.config内容

7.在controllers目录下创建控制器DemoController,然后添加几个方法:

using HttpSelfHost.model;
using System;
using System.Collections.Generic;
using System.Web.Http;

namespace HttpSelfHost.WebApi.controllers
{
public class DemoController:ApiController
{
[HttpGet]
[HttpPost]
public dynamic allStudents()
{
return new
{
result = true,
desc = "请求成功",
data = new List<StudentInfo>()
{
new StudentInfo
{
ClassId="ClassID982712311231",
Sex="男",
StudentId=Guid.NewGuid().ToString(),
StudentName="男学生一枚",
StudentNumber="XH2018090001"
},
new StudentInfo
{
ClassId="ClassID982712311232",
Sex="女",
StudentId=Guid.NewGuid().ToString(),
StudentName="女学生一枚",
StudentNumber="XH2018090002"
}
}
};
}
[HttpGet]
[HttpPost]
public dynamic queryStudents([FromBody]string name)
{
return new
{
result = true,
desc = "查询请求成功,参数name:"+name,
data = new List<StudentInfo>()
{
new StudentInfo
{
ClassId="ClassID982712311231",
Sex="男",
StudentId=Guid.NewGuid().ToString(),
StudentName="男学生一枚",
StudentNumber="XH2018090001"
},
new StudentInfo
{
ClassId="ClassID982712311232",
Sex="女",
StudentId=Guid.NewGuid().ToString(),
StudentName="女学生一枚",
StudentNumber="XH2018090002"
}
},
page=1,
total=2,
pageCount=1
};
}
[HttpGet]
[HttpPost]
public dynamic saveStudents([FromBody]StudentInfo info)
{
info.StudentId = Guid.NewGuid().ToString();
return new
{
result = true,
desc = "保存成功,学生姓名:" + info.StudentName,
data = info.StudentId
};
}
}
}

添加控制器

8. 接下来就可以在应用中启动HTTP服务了:

using System;

namespace HttpSelfHost
{
class Program
{
static void Main(string[] args)
{
StartServer();
String inputStr = null;
while ((inputStr = Console.ReadLine()).ToLower() != "exit")
{

}
}
static public void StartServer()
{
WebApi.WebServer.MessageEvent += WebServer_MessageEvent;
WebApi.WebServer.Start();
}

private static void WebServer_MessageEvent(string msg)
{
Console.WriteLine(msg);
}
}
}

运行一下:
运行SelfHostHttp
运行SelfHostHttp

我们在浏览器中测试一下接口:
Get测试
Get测试

带参数Get测试
Post测试
Post测试
Post对象提交
Post对象提交
Post对象提交
Post对象提交

接下来,我们测试静态文件请求

9.在生成的输出目录创建文件夹HttpPages:
创建静态文件目录
创建静态文件目录

10. 然后将HTML文件和需要的CSS,JS一股脑儿拷贝进去:

11.在VS的解决方案管理器中,点击右上角的"显示所有文件":

然后展开bin/Debug,右键选择HttpPages,弹出的菜单中选择"包括在项目中":

在pages目录下添加一个测试的html文件,包含vue,iview等脚本和css,注意引用的相对位置:

OK,接下来启动程序,看看打开网页是什么情况:
静态文件请求
静态文件请求

看起来还不错.
