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
Install-Package Microsoft.Extensions.Configuration
Install-Package Microsoft.Extensions.Configuration.Json
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": ""
}
}
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Session
var 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", ); 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
