近来学习了一下Nancy这个框架，感觉挺好用的，就写篇简单的文章记录一下大致用法，由于是刚接触，写的代码
可能不规范，也没有具体的分层。。莫吐槽。。。
Nancy的官网：http://nancyfx.org/
GitHub地址:https://github.com/NancyFx/Nancy
Nancy在文档的介绍 -- 轻量级
" Nancy is a lightweight, low-ceremony, framework for building HTTP based services on .NET and Mono. "
Nancy有多种Hosting:
Hosting Nancy with ASP.NET
Hosting Nancy with WCF
Hosting Nancy with Azure
Hosting Nancy with OWIN
Web (Katana)
Self Hosting
Environment Variables
Conditional Pass-through
Hosting Nancy with Umbraco
Hosting Nancy with Nginx on Ubuntu
Hosting Nancy with FastCgi
Self Hosting Nancy
Implementing a Host
Accessing the client certificate when using SSL
本文写的Demo是基于Hosting Nancy with ASP.NET。
开发环境 :win 10 + VS2015 Community + SqlServer 2012
废话不多说，开始正题：
一、新建一个空的asp.net项目
建好之后空空如也
二、通过NuGet添加Nancy相关的Packages
主要是Nancy、Nancy.Hosting.Aspnet、Nancy.Viewengines.Razor这三个。其版本依次为1.4.3、1.4.1、1.4.3
我这里选择的视图引擎是Razor，习惯了，你们可以选择其他，这个问题不大。
三、更新一下Razor
默认安装Nancy.Viewengines.Razor之后，它会安装 Microsoft.AspNet.Razor.2.0.30506.0，我们用的是最新版的3.2.3
在NuGet通过已安装的Packages来更新
到这里，基本的工作已经OK了。
这里用到了Dapper，所以我也添加了它的引用。
注：这里是通过NuGet安装的，所以它也在web.config里生成了一些配置。如果是手动添加引用的，注意要修改web.config。
四、加入css和javascript文件
允许我偷偷懒，这里的我是直接copy一般新建mvc项目的，就连页面布局也是用的新建项目的模板。。
五、新建Modules、Models、ViewModels、Views四个文件夹
Modules-->相当于MVC中的Controllers文件夹
Models-->存放模型
ViewModels-->存放视图模型
Views-->存放视图
六、在Views下面建一个布局页_Layout.cshtml
就新建的mvc模板copy过来，稍加修改
@inherits Nancy.ViewEngines.Razor.NancyRazorViewBase<dynamic>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>@ViewBag.Title - Catcher's NancyDemo</title>
<link href="~/Content/bootstrap.min.css" rel="stylesheet" />
<link href="~/Content/Site.css" rel="stylesheet" />
<link rel="shortcut icon" href="~/favicon.ico" />
</head>
<body>
<div class="navbar navbar-inverse navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">

<span class="icon-bar"></span>
</button>
<a href="/" class="navbar-brand">NancyDemo</a>
</div>
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li><a href="/">首页</a></li>
<li><a href="/home/about">关于我们</a></li>
<li><a href="/home/contact">联系我们</a></li>
<li><a href="/movie/">电影</a></li>
<li><a href="/movie-type/">类型</a></li>
</ul>
</div>
</div>
</div>
<div class="container body-content">
@RenderBody()
<hr />
<footer>
<p>© @DateTime.Now.Year - My ASP.NET Application</p>
</footer>
</div>
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/bootstrap.min.js"></script>
</body>
</html>
_Layout.cshtml
七、在Modules下新建一个HomeModules.cs,具体如下：
public class HomeModule : NancyModule
{
public HomeModule()
{
Get["/"] = _ => ShowHomePage();
Get["/home/about"] = _ => ShowAboutPage();
Get["/home/contact"] = _ => ShowContactPage();
} private dynamic ShowContactPage()
{
return View["Contact"];
} private dynamic ShowAboutPage()
{
return View["About"];
} private dynamic ShowHomePage()
{
return View["Index"];
}
}
HomeModule.cs
同时在Views文件夹下面新建一个Home的子文件夹，在把mvc模板中的Index.cshtml，About.cshtml，Contact.cshtml
copy过来稍加修改
@inherits Nancy.ViewEngines.Razor.NancyRazorViewBase<dynamic>
@{
ViewBag.Title = "首页";
Layout = "Views/_Layout.cshtml";
}
<div class="jumbotron">
<h1>NancyDemo</h1>
<p class="lead">Nancy is a lightweight, low-ceremony, framework for building HTTP based services on .NET and Mono. The goal of the framework is to stay out of the way as much as possible and provide a super-duper-happy-path to all interactions.</p>
<p><a href="http://nancyfx.org/" class="btn btn-primary btn-lg">Learn more »</a></p>
</div>
Index.cshtml
@inherits Nancy.ViewEngines.Razor.NancyRazorViewBase<dynamic>
@{
ViewBag.Title = "About";
Layout = "Views/_Layout.cshtml";
}
<h2>@ViewBag.Title.</h2>
<p>Use this area to provide additional information.</p>
About.cshtml
@inherits Nancy.ViewEngines.Razor.NancyRazorViewBase<dynamic>
@{
ViewBag.Title = "Contact";
Layout = "Views/_Layout.cshtml";
}
<h2>@ViewBag.Title.</h2> <address>
One Microsoft Way<br />
Redmond, WA -<br />
<abbr title="Phone">P:</abbr>
425.555.
</address> <address>
<strong>Support:</strong> <a href="mailto:Support@example.com">Support@example.com</a><br />
<strong>Marketing:</strong> <a href="mailto:Marketing@example.com">Marketing@example.com</a>
</address>
Contact.cshtml
然后F5，跑一下
已经能跑起来了。
下面就是结合数据库了。
八、在MOdels下面建两个类
public class Movie
{
public int MovieId { get; set; } public string MovieName { get; set; } public int MovieTypeId { get; set; } public DateTime MovieAddTime { get; set; } public virtual MovieType MovieType { get; set; } public Movie()
{
MovieAddTime = DateTime.Now;
}
}
Movie.cs
public class MovieType
{
public MovieType()
{
Movies = new HashSet<Movie>();
} public int TypeId { get; set; } public string TypeName { get; set; } public virtual ICollection<Movie> Movies { get; set; }
}
MovieType.cs
以Movie表为例，继续下面的工作。
九、由于movie表中的数据展示，抽取出应该有的视图模型
在ViewModels文件夹下面建立MovieViewModel.cs、MovieListViewModel.cs
public class MovieViewModel
{
public int MovieId { get; set; } public string MovieName { get; set; } public int MovieTypeId { get; set; } public string MovieTypeName { get; set; } public DateTime MovieAddTime { get; set; }
}
MovieViewModel.cs
public class MovieListViewModel
{
public IEnumerable<MovieViewModel> Movies { get; set; }
}
MovieListViewModel.cs
十、现在就该写写烦人mvc控制器的东西了，在Modules文件夹下建立MovieModules.cs
把数据提取出来
public class MovieModule : NancyModule
{
public MovieModule() : base("/movie")
{
Get["/"] = _ => ShowMovieIndexPage();
} private readonly string _sqlconnection =
"Data Source=192.168.0.71;Initial Catalog=NancyDemo;User Id=sa;Password=dream_time1314;"; public SqlConnection OpenConnection()
{
SqlConnection connection = new SqlConnection(_sqlconnection);
connection.Open();
return connection;
} private dynamic ShowMovieIndexPage()
{
using (IDbConnection conn = OpenConnection())
{
string getAllMoviesStoredProcedure = @"up_GetAllMovies";
MovieListViewModel viewModel = new MovieListViewModel
{
Movies = conn.Query<MovieViewModel>(getAllMoviesStoredProcedure,
null, null, true, null, CommandType.StoredProcedure)
};
return View["Index", viewModel];
}
}
}
MovieModule.cs
然后就去编写视图
在Views下面新建一个Movie文件夹，用于存放相关视图
@inherits Nancy.ViewEngines.Razor.NancyRazorViewBase<MovieDemo.ViewModels.MovieListViewModel>
@{
Layout = "Views/_Layout.cshtml";
ViewBag.Title = "电影列表";
}
<a href="/movie/create">添加</a>
<div>
<table class="table">
<tr>
<th>
#
</th>
<th>
电影名称
</th>
<th>
电影类型
</th>
<th>
添加时间
</th>
<th></th>
</tr>
@foreach (var item in Model.Movies)
{
<tr>
<td>
@item.MovieId
</td>
<td>
@item.MovieName
</td>
<td>
@item.MovieTypeName
</td>
<td>
@item.MovieAddTime
</td>
<td>
<a href="/movie/edit/@item.MovieId">修改</a>
<a class="delete" href="/movie/delete/@item.MovieId">删除</a>
</td>
</tr>
}
</table>
</div>
Index.cshtml
F5跑一下
OK！
然后就是修改某条数据，
在MovieModule.cs 的构造函数中添加
Get["/edit/{movieId}"] = _ => ShowMovieEditPage(_.movieId);
Post["/edit/{movieId}"] = _ =>
{
var movie = this.Bind<Movie>();
return MovieEdit(movie);
};
然后添加ShowMovieEditPage和MovieEdit这两个方法
private dynamic ShowMovieEditPage(int movieId)
{
string getOneMovieStoredProcedure = @"up_GetMovieByMovieId";
string getALLTypeStoredProcedure = @"up_GetAllMovieTypes";
DynamicParameters dynamicParameters = new DynamicParameters();
dynamicParameters.Add("@MovieId", movieId); using (IDbConnection conn = OpenConnection())
{
var movieViewModel = conn.Query<MovieViewModel>(getOneMovieStoredProcedure, dynamicParameters, null, true, null, CommandType.StoredProcedure).SingleOrDefault();
ViewBag.typeList = conn.Query<MovieType>(getALLTypeStoredProcedure, null, null, true, null, CommandType.StoredProcedure);
return View["Edit", movieViewModel]; }
}
ShowMovieEditPage
private dynamic MovieEdit(Movie movie)
{
string updateMovieStoredProcedure = @"up_UpdateMovieByMovieId";
DynamicParameters dynamicParameters = new DynamicParameters();
dynamicParameters.Add("@MovieId", movie.MovieId);
dynamicParameters.Add("@MovieName", movie.MovieName);
dynamicParameters.Add("@MovieTypeId", movie.MovieTypeId); using (IDbConnection conn = OpenConnection())
{
conn.Execute(updateMovieStoredProcedure, dynamicParameters, null, null, CommandType.StoredProcedure);
return Response.AsRedirect("/movie");
}
}
MovieEdit
添加一个Movie的Edit视图
@inherits Nancy.ViewEngines.Razor.NancyRazorViewBase<MovieDemo.ViewModels.MovieViewModel>
@{
ViewBag.Title = "修改电影信息";
Layout = "Views/_Layout.cshtml";
} <form action="/movie/edit/@Model.MovieId" method="post">
<div class="form-group">
<label class="control-label col-md-2">电影名称</label>
<div class="col-md-10">
<input type="text" class="form-control" id="MovieName" name="MovieName" value="@Model.MovieName" />
</div>
</div>
<div class="form-group">
<label class="control-label col-md-2">电影类型</label>
<div class="col-md-10">
<select id="MovieTypeId" name="MovieTypeId" class="form-control">
@foreach (var item in (System.Collections.Generic.List<MovieDemo.Models.MovieType>)ViewBag.typeList)
{
if (Model.MovieTypeId == item.TypeId)
{
<option selected="selected" value="@item.TypeId">@item.TypeName</option>
}
else
{
<option value="@item.TypeId">@item.TypeName</option>
}
} </select>
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="修改" class="btn btn-default" />
</div>
</div>
</form>
Edit.cshtml
然后即可跑起来了。
其中用到了一个模型绑定，需要添加Nancy.ModelBinding引用，有了这个绑定，省了很多事！！
var movie = this.Bind<Movie>();
同理，增加和删除也是同样的做法，下面是MovieModule.cs的完整代码
using MovieDemo.Models;
using MovieDemo.ViewModels;
using Dapper;
using Nancy;
using Nancy.ModelBinding;
using System.Data;
using System.Data.SqlClient;
using System.Linq; namespace MovieDemo.Modules
{
public class MovieModule : NancyModule
{
public MovieModule() : base("/movie")
{
Get["/"] = _ => ShowMovieIndexPage(); Get["/edit/{movieId}"] = _ => ShowMovieEditPage(_.movieId);
Post["/edit/{movieId}"] = _ =>
{
var movie = this.Bind<Movie>();
return MovieEdit(movie);
}; Get["/create"] = _ => ShowMovieCreatePage();
Post["/create"] = _ =>
{
var movie = this.Bind<Movie>();
return MovieCreate(movie);
}; Get["/delete/{movieId}"] = _ => MovieDelete(_.movieId);
} private readonly string _sqlconnection =
"Data Source=192.168.0.71;Initial Catalog=NancyDemo;User Id=sa;Password=dream_time1314;"; public SqlConnection OpenConnection()
{
SqlConnection connection = new SqlConnection(_sqlconnection);
connection.Open();
return connection;
} private dynamic MovieDelete(int movieId)
{
string deleteMovieStoredProcedure = @"up_DeleteMovieByMovieId";
DynamicParameters dynamicParameters = new DynamicParameters();
dynamicParameters.Add("@MovieId", movieId);
using (IDbConnection conn = OpenConnection())
{
conn.Execute(deleteMovieStoredProcedure, dynamicParameters, null, null, CommandType.StoredProcedure);
return Response.AsRedirect("/movie");
}
} private dynamic MovieCreate(Movie movie)
{
string createMovieStoredProcedure = @"up_InsertMovie";
DynamicParameters dynamicParameters = new DynamicParameters();
dynamicParameters.Add("@MovieName", movie.MovieName);
dynamicParameters.Add("@MovieTypeId", movie.MovieTypeId);
dynamicParameters.Add("@MovieAddTime", movie.MovieAddTime); using (IDbConnection conn = OpenConnection())
{
conn.Execute(createMovieStoredProcedure, dynamicParameters, null, null, CommandType.StoredProcedure);
return Response.AsRedirect("/movie");
}
} private dynamic ShowMovieCreatePage()
{
string getALLTypeStoredProcedure = @"up_GetAllMovieTypes";
using (IDbConnection conn = OpenConnection())
{
MovieTypeListViewModel viewModel = new MovieTypeListViewModel
{
MovieTypes = conn.Query<MovieType>(getALLTypeStoredProcedure, null, null, true, null, CommandType.StoredProcedure)
};
return View["Create", viewModel];
}
} private dynamic MovieEdit(Movie movie)
{
string updateMovieStoredProcedure = @"up_UpdateMovieByMovieId";
DynamicParameters dynamicParameters = new DynamicParameters();
dynamicParameters.Add("@MovieId", movie.MovieId);
dynamicParameters.Add("@MovieName", movie.MovieName);
dynamicParameters.Add("@MovieTypeId", movie.MovieTypeId); using (IDbConnection conn = OpenConnection())
{
conn.Execute(updateMovieStoredProcedure, dynamicParameters, null, null, CommandType.StoredProcedure);
return Response.AsRedirect("/movie");
}
} private dynamic ShowMovieEditPage(int movieId)
{
string getOneMovieStoredProcedure = @"up_GetMovieByMovieId";
string getALLTypeStoredProcedure = @"up_GetAllMovieTypes";
DynamicParameters dynamicParameters = new DynamicParameters();
dynamicParameters.Add("@MovieId", movieId); using (IDbConnection conn = OpenConnection())
{
var movieViewModel = conn.Query<MovieViewModel>(getOneMovieStoredProcedure, dynamicParameters, null, true, null, CommandType.StoredProcedure).SingleOrDefault();
ViewBag.typeList = conn.Query<MovieType>(getALLTypeStoredProcedure, null, null, true, null, CommandType.StoredProcedure);
return View["Edit", movieViewModel]; }
} private dynamic ShowMovieIndexPage()
{
using (IDbConnection conn = OpenConnection())
{
string getAllMoviesStoredProcedure = @"up_GetAllMovies";
MovieListViewModel viewModel = new MovieListViewModel
{
Movies = conn.Query<MovieViewModel>(getAllMoviesStoredProcedure,
null, null, true, null, CommandType.StoredProcedure)
};
return View["Index", viewModel];
}
}
}
}
MovieModule.cs
在添加相应的视图即可完成。
十一、下面还需要简单讲一下Bootstrapper
这个东西可以简单认为是引导程序，你可以自定义一些鬼东西，把它当作一个容器来用，
还可以通过它来实现依赖注入，里面有个默认的 TinyIoC 。。。。。详细介绍请看https://github.com/NancyFx/Nancy/wiki/Bootstrapper
下面是我的CustomBootstrapper.cs配置
public class CustomBootstrapper : DefaultNancyBootstrapper
{
protected override void ConfigureApplicationContainer(TinyIoCContainer container)
{
base.ConfigureApplicationContainer(container);
//container.Register<IMoviesRepository, MoviesRepository>();
//container.Register<IMovieTypesRepository, MovieTypesRepository>();
}
protected override void ConfigureConventions(NancyConventions nancyConventions)
{
base.ConfigureConventions(nancyConventions);
nancyConventions.StaticContentsConventions.Add(StaticContentConventionBuilder.AddDirectory("Scripts"));
nancyConventions.StaticContentsConventions.Add(StaticContentConventionBuilder.AddDirectory("Content"));
}
}
CustomBootstrapper.cs
依赖注入我是没有用的，所以我注释了。用过Ninject、Autofac、Unity这些的，相信依赖注入这一块理解起来So easy！
Nancy也有相应的拓展
https://github.com/NancyFx/Nancy.Bootstrappers.Autofac
https://github.com/NancyFx/Nancy.Bootstrappers.Unity
https://github.com/NancyFx/Nancy.Bootstrappers.Ninject
还有一块是ConfigureConventions
这一块似乎是用来处理静态文件(css、js)的，跟Mvc中的BundleConfig很类似
到这里，开发工作已经完成。下面是部署的时候了。
十二、将做的MovieDemo部署到Linux下
Linux环境及配置
CentOS 6.7 + mono 4.2.2 + Jexus 5.8.0
将发布过后的目录上传到centos的 /var/www/ 中，然后在 /usr/jexus/siteconf 中建立一个新的配置文件
重新启动jexus即可。
下面上几张运行的图
完全的无缝兼容。

下雨天，心情压抑，写篇bolg来拯救自己的好心情 ~_~
后面有时间会写基于owin的demo
