NET Core & VS Code 之路(2) Web API

开发Core项目的条件

看到VS包的体积,以及不想往下走了.

幸亏,ms出了VS Code,可开发.NET Core项目.实际上记事本也能写Core代码,但是开发是需要调试的.

所以本系列将持续用VS Code开发.以代码为主,关键点会加以注释

由于公司事比较多,一直没来得及更新

Web API

dotnet new 添加Core项目
project.json添加依赖
- "Microsoft.AspNetCore.Server.Kestrel"
- "Microsoft.AspNetCore.Mvc"
添加Startup.cs
添加ValuesController.cs
修改Program.cs

project.json 添加的依赖

"dependencies": {

"Microsoft.AspNetCore.Server.Kestrel": "1.0.0", //webhost

"Microsoft.AspNetCore.Mvc": "1.0.0" //webapi mvc

}

添加的Startup.cs

using Microsoft.AspNetCore.Builder;

using Microsoft.Extensions.DependencyInjection;

public class Startup

{

public void Configure(IApplicationBuilder app)

{

app.UseMvc();//使用MVC管道

}

public void ConfigureServices(IServiceCollection services)

{

services.AddMvc();//MVC加入到DI容器中

}

添加的ValuesController.cs

using Microsoft.AspNetCore.Mvc;

public class ValuesController

{

[HttpGet("/values/{name}")]//name参数注入

public string Index(string name)

{

return "Hello World:" + name;

}

修改的Program.cs

public static void Main(string[] args)

{

new WebHostBuilder()

.UseKestrel()

.UseStartup<Startup>()

.UseUrls("http://localhost:8899", "http://localhost:9988/")//同时监听2个端口

.Build()

.Run();

}

MVC

在.NET Core中,MVC和Web API实际上走的同一个管道

本例子会在上面的Web API基础上修改

添加和修改project.json
- Microsoft.AspNetCore.Razor.Tools
添加HomeController
添加Index.cshtml
修改Program.cs

MVC中因为有razor动态编译,所以不仅仅添加1个依赖即可

project.json修改的内容

"buildOptions": {

"debugType": "portable",

"emitEntryPoint": true,

"preserveCompilationContext": true //动态编译

},

"dependencies": {

"Microsoft.AspNetCore.Server.Kestrel": "1.0.0", //webhost

"Microsoft.AspNetCore.Mvc": "1.0.0", //webapi mvc

"Microsoft.AspNetCore.Razor.Tools": { //mvc razor

"version": "1.0.0-preview2-final",

"type": "build"

}

},

添加的HomeController.cs

注意:需要继承Controller类

using Microsoft.AspNetCore.Mvc;

public class HomeController : Controller

{

[HttpGet("/{name}")]

public IActionResult Index(string name)

{

ViewBag.Name = "Hello " + name;

return View();

}

添加Index.cshtml

目录结构和之前方式(ASP.NET MVC)一样

<!DOCTYPE html>

<html lang="zh">

<head>

<meta charset="UTF-8">

<title>Title</title>

</head>

<body>

<h1>@ViewBag.Name</h1>

</body>

</html>

修改Program.cs

public static void Main(string[] args)

{

new WebHostBuilder()

.UseKestrel()

.UseStartup<Startup>()

.UseContentRoot(Directory.GetCurrentDirectory()) //mvc views需要

.UseUrls("http://localhost:8899", "http://localhost:9988/")//同时监听2个端口

.Build()

.Run();

}

静态文件

添加依赖:project.json
- Microsoft.AspNetCore.StaticFiles
注册管道:Startup.cs
添加静态文件:wwwroot

project.json

"dependencies": { //nuget包

"Microsoft.AspNetCore.Mvc": "1.0.0", //webapi mvc

"Microsoft.AspNetCore.Server.Kestrel": "1.0.0", //webhost

"Microsoft.AspNetCore.Razor.Tools": { //mvc razor

"version": "1.0.0-preview2-final",

"type": "build"

},

"Microsoft.AspNetCore.StaticFiles": "1.0.0"//静态文件

},

注册管道

public void Configure(IApplicationBuilder app)

{

app.UseStaticFiles();//需要在mvc前否则将优先被mvc路由匹配执行

app.UseMvc();

}

添加静态文件

静态文件默认是以wwwroot文件夹为根目录

注意:

添加依赖后,需要Restore后才能使用该库
