.net Core 2.1 ?MVC+EF+Redis搭建-我的编程学习网

官方学习资料

搭建空MVC框架

1.创建一个空模板

2.创建文件夹 Controllers、Models、Views

3.在Controllers文件夹下创建HomeController.cs

选择Controllers文件夹，右键-添加-新建项，选择MVC控制器类，添加HomeController.cs。

using System;using System.Collections.Generic;using System.Linq;using System.Threading.Tasks;using Microsoft.AspNetCore.Http;using Microsoft.AspNetCore.Mvc;namespace RazorMvc.Controllers{ ???public class HomeController : Controller ???{ ???????// GET: Home ???????public ActionResult Index() ???????{ ???????????return View(); ???????} ???}}

4.在Models文件夹下创建HomeModel.cs

using System;using System.Collections.Generic;using System.Linq;using System.Threading.Tasks;namespace RazorMvc.Models{ ???public class HomeModel ???{ ???}}

5.在Views文件夹中添加_Layout.cshtml

<!DOCTYPE html><html lang="en"><head> ???<meta charset="UTF-8"> ???<meta name="viewport" content="width=device-width, initial-scale=1.0"> ???<meta http-equiv="X-UA-Compatible" content="ie=edge"> ???<title>@ViewData["Title"]</title></head><body> ???@RenderBody() ???@RenderSection("Scripts", false)</body></html>

6.在Views文件夹中添加_ViewStart.cshtml

@{ ???Layout = "~/Views/_Layout.cshtml";}

7.在Views文件夹中添加_ViewImports.cshtml

@using 项目命名空间@using 项目命名空间.Models@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers

8.调整Startup.cs

public void ConfigureServices(IServiceCollection services){ ?????services.AddMvc();//注册服务}public void Configure(IApplicationBuilder app, IHostingEnvironment env){ ???if (env.IsDevelopment()) ???{ ???????app.UseDeveloperExceptionPage(); ???} ???else ???{ ???????app.UseExceptionHandler("/Home/Error"); ???????app.UseHsts(); ???} ???app.UseHttpsRedirection(); ???app.UseStaticFiles(); ???app.UseCookiePolicy(); ???app.UseSession(); ???app.UseMvc(routes => ???{ ???????routes.MapRoute( ???????????name: "default", ???????????template: "{controller=Home}/{action=Index}/{id?}"); ???});}

9.调整完成后可保存为模板（可跳过，等后面完事一起存）

EF Core搭建

1.安装 EF Core

工具 > NuGet 包管理器 > 包管理器控制台
运行 Install-Package Microsoft.EntityFrameworkCore.SqlServer
运行 Install-Package Microsoft.EntityFrameworkCore.Tools
运行 Install-Package Microsoft.VisualStudio.Web.CodeGeneration.Design
听话全安了

2.从现有数据库创建模型

Scaffold-DbContext"Server=.;Database=test;uid=test;pwd=test;"Microsoft.EntityFrameworkCore.SqlServer-OutputDirModels

可以通过将-Tables参数添加到上述命令来指定要为哪些表生成实体。例如-Tables Blog,Post。

3.删除内联上下文配置

打开Models\BloggingContext.cs
删除OnConfiguring(...)方法

4.在 Startup.cs 中注册并配置上下文

public void ConfigureServices(IServiceCollection services){ ???services.AddMvc(); ???var connection = @"Server=.;Database=test;uid=test;pwd=test;"; ???services.AddDbContext<testContext>(options => options.UseSqlServer(connection));}

5.系统生成测试页面

在“解决方案资源管理器”中，右键单击“控制器”文件夹，然后选择“添加”->“控制器…”
选择“视图使用 Entity Framework 的 MVC 控制器”，然后单击“确定”
将“模型类”设置为“Test”，将“数据上下文类”设置为“TestContext”
单击“添加”
可运行起来测试数据库连接

使用Redis存储Session

//根据自己需要修改配置文件，此处直接https://www.cnblogs.com/shouwu/p/6180652.html，

1.添加nuget程序包

Microsoft.AspNetCore.Session;Microsoft.AspNetCore.DataProtection.Redis;Microsoft.Extensions.Caching.Redis.Core;Microsoft.AspNetCore.Http; ????//使用Session时有扩展方法

2.在appsettings.json中添加Redis配置

{ ?"Logging": { ???"LogLevel": { ?????"Default": "Warning" ???} ?}, ?"AllowedHosts": "*", ?"WebConfig": { ???"Redis": { ?????"Connection": "ip:6379,allowAdmin=true,password=Test", ?????"InstanceName": "名称" ???}, ???"SessionTimeOut": "30" ?}}

3.在startup.cs类中，按如下例子添加代码

public IConfiguration Configuration { get; }public Startup(IConfiguration configuration){ ???Configuration = configuration;}

ConfigureServices() 增加

#region 使用Redis保存Sessionvar redisConn = Configuration["WebConfig:Redis:Connection"];var redisInstanceName = Configuration["WebConfig:Redis:InstanceName"];//Session 过期时长分钟var sessionOutTime = Configuration.GetValue<int>("WebConfig:SessionTimeOut", 30);var redis = StackExchange.Redis.ConnectionMultiplexer.Connect(redisConn);services.AddDataProtection().PersistKeysToRedis(redis, "DataProtection-Test-Keys");services.AddDistributedRedisCache(option =>{ ???//redis 连接字符串 ???option.Configuration = redisConn; ???//redis 实例名 ???option.InstanceName = redisInstanceName;});#endregion//添加Session并设置过期时长services.AddSession(options => { options.IdleTimeout = TimeSpan.FromMinutes(sessionOutTime); });

Configure() 在app.UseMvc之前增加

app.UseSession();

Redis存储Session

HttpContext.Session.SetString("UserName", userName);HttpContext.Session.GetString("UserName");

普通存储Redis

public IDistributedCache _RCache { get; set; }public MyToolController(IDistributedCache RCache){ ???_RCache = RCache;}_RCache.SetString("UserName", UserName);_RCache.GetString("UserName");

附加

JS/CSS 压缩 Install-Package YUICompressor.NET

JS压缩

JavaScriptCompressor jsCompressor = new JavaScriptCompressor{ ???//使用utf-8 编码文件 ???Encoding = Encoding.UTF8};jsCompressor.Compress(str);

Css压缩

CssCompressor cssCompressor = new CssCompressor();cssCompressor.Compress(str);

安装结束后包数量，无任何参考价值hhh
