• 代码仓库地址：

• 所用到的框架和插件：

一、创建.Net环境

1.1环境配置

1.1.1 使用vscode创建webapi

1. 创建ReStore文件夹

mkdir ReStore

2. 创建新的sln

dotnet new sln

3. 创建一个名为API的项目

donete new webapi -o API

4. 给解决方案里添加项目

dotnet sln add API

5. 进入到项目文件夹内，运行程序

donet run 

6. 访问 http://localhost:5172/swagger，成功

1.1.2 Clean architecture结构创建

• 引用关系图
  

1.1.3 将创建好结构的项目添加到git里

• 结构
  

• 前提：Git里有一个空的仓库ReStoreApi且没有master分支

#1.初始化本地仓库
git init

#2. 上传代码到本地仓库
git add .
git commit -m "Initial commit"

#3. 将远程仓库添加为 origin
git remote add origin https://github.com/CXTV/ReStoreApi.git

#4.确保正确设置分支
git branch -M main

#5. 推送代码到远程仓库
git push -u origin main

1.1.4 EF Core配置

1. 在infrastructure里安装EF所需环境

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="9.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="9.0.0">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="9.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="9.0.0">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

2. 创建Product数据模型

• 在ReStore.Domain/Models/Product.cs里创建Product表的模型

namespace ReStore.Domain.Models
{
   
    public class Product
    {
   
        public int Id {
    get; set; }
        public string Name {
    get; set; }
        public string Description {
    get; set; }
        public long Price {
    get; set; }
        public string PictureUrl {
    get; set; }
        public string Type {
    get; set; }
        public string Brand {
    get; set; }
        public int QuantityInStock {
    get; set; }
    }
}

3. 创建EF Core的DbContext 数据库上下文

• 在ReStore.Infrastructure/Persistance/ReStoreDbContext.cs里创建EF的数据库上下文，用来管理数据操作是数据库和程序的桥梁

using Microsoft.EntityFrameworkCore;
using ReStore.Domain.Models;

namespace ReStore.Infrastructure.Persistance
{
   
    internal class ReStoreDbContext : DbContext
    {
   
        public ReStoreDbContext(DbContextOptions<ReStoreDbContext> options) : base(options)
        {
   

        }
        public DbSet<Product> Products {
    get; set; }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
   
        }
    }
}

4. 创建Extensions用来管理服务注入

创建ReStore.Infrastructure/Extensions/ServiceCollectionExtensions.cs ，Infrustructure 层的所有服务注册，都在该文件里进行，这样可以保持program.cs文件的结构整洁

using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using ReStore.Infrastructure.Persistance;
using ReStore.Infrastructure.Seeds;

namespace ReStore.Infrastructure.Extensions
{
   
    public static class ServiceCollectionExtensions
    {
   
        //将program.cs中的服务注册移到这里
        public static void AddInfrastructure(this IServiceCollection services,
