2016年，.net 会有很多大更新 ASP.NET 5
在此之前我都是用着古老的.net做开发的 (WebForm + IIS)
为了接下来应对 .net 的新功能，我特地去学习了一下基本的 MVC Owin 等等.
接下来我会针对主题写一些学习笔记.
Setup startup Owin + MVC + WebApi
1.New empty project and add folders and code references for "MVC, WebApi".
注: Empty project 就是什么sample都不要有的, add folders and code references 就是要包括 dll , 这里的 MVC 和 WebApi 都是没有包含Owin概念的，我们需要之后自己加入哦。
2.Install "Microsoft.Owin.Host.SystemWeb" (This is for host in IIS)
3.Install "Microsoft.AspNet.WebApi.Owin" (WebApi for OWIN)
3.Add a Startup.cs file with below code
using System.Web.Http;
using System.Web.Mvc;
using System.Web.Routing;
using Microsoft.Owin;
using Owin; [assembly: OwinStartupAttribute(typeof(Project.Startup))]
namespace Project
{
public partial class Startup
{
public void Configuration(IAppBuilder app)
{
//MVC
AreaRegistration.RegisterAllAreas();
RouteConfig.RegisterRoutes(RouteTable.Routes); //WebApi
var httpConfig = new HttpConfiguration();
WebApiConfig.Register(httpConfig);
app.UseWebApi(httpConfig);
}
}
}
4.Remove Global.asax
Startup.cs 就是for Owin 的，我们不再使用 IIS 的 Global.asax 了.
Sample MVC (Model, View and Controller)
微软有一些folders的的结构，我们可以参考 follow
Model,View,Controller 各一个folder
View/Shared 放一些sharing的view
View/Shared/_Layout.cshtml 布局
View/_ViewStart.cshtml 每一个view的初始化
Example for _ViewStart.cshtml
@{
Layout = "~/Views/Shared/_Layout.cshtml"; //每一个View 都是用 _Layout.cshtml 布局, 这个是可以被overwrite掉了.
}
Example for _Layout.cshtml
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>@ViewBag.Title</title>
<link href="~/Content/bootstrap.min.css" rel="stylesheet" /> @*可以直接用 "~/"*@
@RenderSection("css", required: false) @*RenderSection 可以在子 View 填入内容*@
</head>
<body>
@RenderBody() @*这个个子 View 内容*@
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
@RenderSection("script", required: false)
</body>
</html>
Controller, Model 与 View 之间的沟通
Example Controller
using System.Collections.Generic;
using System;
using System.Web.Mvc;
using Project.Models;
using System.Threading.Tasks; namespace Project.Controllers
{
[RoutePrefix("")]
public class HomeController : AsyncController //Async 可以for EF await
{
[Route("", Name = "Home")]
public async Task<ActionResult> Index(string param)
{
ViewData["attr"] = "value"; //passing value by 字典
ViewBag.attr = "value"; // passing value by dynamic
ViewBag.listStr = new List<string> { "a", "b", "c" };
HomeViewModels homeVM = new HomeViewModels //passing value by ViewModel
{
content = "strContent",
headerViewModels = new HeaderViewModels
{
content = "headerContent"
}
};
return View(homeVM);
}
}
}
Example Model
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web; namespace Project.Models
{
public class HomeViewModels
{
public string content { get; set; }
public HeaderViewModels headerViewModels { get; set; }
} public class HeaderViewModels
{
public string content { get; set; }
}
}
如果多的话，可以一个ViewModels 一个 file
Example View
@*初始化*@
@{
ViewBag.title = "Home";
Layout = "~/Views/Shared/_Layout.cshtml";
} @*setup _Layout.cshtml 的 RenderSection*@
@section css {
<link href="~/Content/Site.css" rel="stylesheet" />
}
@section script {
<script src="~/Scripts/jquery.validate.js"></script>
} @*setup ViewModels*@
@model Project.Models.HomeViewModels <div>
<p>Home</p>
@*渲染一个 partial view*@
@Html.Partial("~/Views/Shared/PartialView/header.cshtml", @Model.headerViewModels); <br />
<p>passing value by 字典 : @ViewData["attr"]</p>
<p>passing value by dynamic : @ViewBag.attr</p> @*looping*@
@foreach (string str in ViewBag.listStr)
{
<p>@str</p>
}
@for (int i = ; i < ViewBag.listStr.Count; i++)
{
<p>@i</p>
} @*create Link*@
<a href="@Url.RouteUrl("Home",new { param = "param" })">Home</a>
<br />
@Html.ActionLink("Home", "Index", "Home", new { param = "param" }, null)
</div>
题外话 :
关于 App_Code
以前我是用 website 而不是 project 来开发的，这2者对 App_Code 有点区别
在 project App_Code 创建好 .cs 文件之后，要把属性 -> Build Action 设置成 Compile
关于 SSL
设置成 SSL, 去project 的属性 -> SSL Enabled = true, 然后 right click -> 属性 -> Web -> 把 project url 换成 SSL 的路径
WebApi + AngularJS
如果要使用 OData filter 的话，应该是要装 Microsoft.AspNet.WebApi.OData
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http; namespace Project.WebApiControllers
{
[RoutePrefix("api/products")]
public class ProductsController : ApiController
{
[Route("")]
public IEnumerable<string> Get()
{
return new string[] { "value1", "value2" };
}
}
}
@{
Layout = null;
}
<!DOCTYPE html>
<html ng-app="app" ng-controller="ctrl">
<head>
<meta name="viewport" content="width=device-width" />
<title>Products</title>
</head>
<body>
<script src="~/Scripts/jquery-2.2.0.min.js"></script>
<script src="~/Scripts/angular.min.js"></script>
<script>
var app = angular.module("app", []);
app.controller("ctrl", function ($http) {
$http({
url: "https://localhost:44300/api/products",
method: "GET"
}).then(function (response) {
console.log(response);
});
});
</script>
</body>
</html>
WebApi + OData v4
Install "Microsoft.AspNet.OData"
change WebApiConfig to
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;
using System.Web.OData.Batch;
using System.Web.OData.Builder;
using System.Web.OData.Extensions;
using Microsoft.OData.Edm;
using Project.Entity; namespace Project
{
public static class WebApiConfig
{
private static IEdmModel GetEdmModel()
{
ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
builder.Namespace = "Project";
builder.ContainerName = "ProjectContainer";
//每一个Entity都要注册到EDM
//注意 : 下面这个 "products" 是url prefix, e.g. api/products... 而且OData url 是区分大小写的哦
builder.EntitySet<Product>("products");
return builder.GetEdmModel();
} public static void Register(HttpConfiguration config)
{
// Web API configuration and services // Web API routes
config.MapHttpAttributeRoutes(); //config.Routes.MapHttpRoute(
// name: "DefaultApi",
// routeTemplate: "api/{controller}/{id}",
// defaults: new { id = RouteParameter.Optional }
//); //"api" 是 url prefix
config.MapODataServiceRoute("OData", "api", GetEdmModel(), new DefaultODataBatchHandler(GlobalConfiguration.DefaultServer));
config.EnsureInitialized();
}
}
}
change WebApiController to
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.OData;
using System.Web.OData.Routing;
using Project.Entity; namespace Project.WebApiControllers
{
[ODataRoutePrefix("products")] //这个"products"要对应注册EDM的值哦 , e.g. builder.EntitySet<Product>("products")
public class ProductsController : ODataController
{
[ODataRoute("")]
public IHttpActionResult Get()
{
return Ok(new List<Product> { new Product { id = , code = "code" } });
}
}
}
Web.config 要放 ExtensionlessUrlHandler 主要是为了处理 url 的 "."
这里我用的和微软官网有点不同，因为微软的放了，static file 会出现500 error

<configuration>
<system.webServer>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="OPTIONSVerbHandler" />
<remove name="TRACEVerbHandler" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="/api/*" verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
</configuration>
Install EntityFramework
在 WebConfig 加入
<configuration>
<connectionStrings>
<add name="DefaultConnection" connectionString="data source=192.168.1.95;Network Library=DBMSSOCN;initial catalog=HotelPlatform;persist security info=True;user id=keatkeat;password=001001;multipleactiveresultsets=True;application name=EntityFramework" providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>
data source = IP
catalog= Database Name
password = 需要encode for xml
删除掉
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
<parameters>
<parameter value="mssqllocaldb" />
</parameters>
</defaultConnectionFactory>
identity + oauth 2.0 待续
