mvc core2.1 Identity.EntityFramework Core 配置 (一）

https://docs.microsoft.com/zh-cn/aspnet/core/security/authentication/customize_identity_model?view=aspnetcore-2.1 参考地址

• 标识模型包含七个实体类型：

  • User -表示的用户
  • Role -表示的角色
  • UserClaim -表示用户拥有的声明
  • UserToken -表示用户的身份验证令牌
  • UserLogin -将用户与一个登录名相关联
  • RoleClaim -表示将授予角色中的所有用户的声明
  • UserRole -加入将用户和角色相关联的实体

  实体类型关系

  这些实体类型通过以下方式彼此相关：

  • 每个User可以具有许多 UserClaims
  • 每个User可以具有许多 UserLogins
  • 每个User可以具有许多 UserTokens
  • 每个Role可以具有许多关联 RoleClaims
  • 每个User可以具有许多关联Roles，和每个Role可以与多个用户相关联
    • 这是一个多对多关系，这需要在数据库中的联接表。 联接表均由表示UserRole实体。

dotnet new mvc -o  IdentityMvc
cd IdentityMvc
dotnet add package Microsoft.AspNetCore.Identity.EntityFrameworkCore

Startup.cs->ConfigureServices

using IdentityMvc.Data;
using Microsoft.EntityFrameworkCore;
using IdentityMvc.Models;
using Microsoft.AspNetCore.Identity;

 services.AddDbContext<ApplicationDbContext>(options =>
                options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

            services.AddIdentity<ApplicationUser, IdentityRole>()
                .AddEntityFrameworkStores<ApplicationDbContext>()
                .AddDefaultTokenProviders();

            services.Configure<IdentityOptions>(options =>
            {
                // Password settings
                options.Password.RequireDigit = true;
                options.Password.RequiredLength = 8;
                options.Password.RequireNonAlphanumeric = false;
                options.Password.RequireUppercase = true;
                options.Password.RequireLowercase = false;
                options.Password.RequiredUniqueChars = 6;

                // Lockout settings
                options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(30);
                options.Lockout.MaxFailedAccessAttempts = 10;
                options.Lockout.AllowedForNewUsers = true;

                // User settings
                options.User.RequireUniqueEmail = true;
            });

            services.ConfigureApplicationCookie(options =>
            {
                // Cookie settings
                options.Cookie.HttpOnly = true;
                options.Cookie.Expiration = TimeSpan.FromDays(150);
                // If the LoginPath isn't set, ASP.NET Core defaults 
                // the path to /Account/Login.
                options.LoginPath = "/Account/Login";
                // If the AccessDeniedPath isn't set, ASP.NET Core defaults 
                // the path to /Account/AccessDenied.
                options.AccessDeniedPath = "/Account/AccessDenied";
                options.SlidingExpiration = true;
            });

Data->ApplicationDbContext 新建

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;
using IdentityMvc.Models;

namespace IdentityMvc.Data
{
    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
            : base(options)
        {
        }

        protected override void OnModelCreating(ModelBuilder builder)
        {
            base.OnModelCreating(builder);
            // Customize the ASP.NET Identity model and override the defaults if needed.
            // For example, you can rename the ASP.NET Identity table names and more.
            // Add your customizations after calling base.OnModelCreating(builder);
        }
    }
}

Models->ApplicationUser 新建

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Identity;

namespace IdentityMvc.Models
{
    // Add profile data for application users by adding properties to the ApplicationUser class
    public class ApplicationUser : IdentityUser
    {
    }
}

appsettings.json 加入数据库连接

  "ConnectionStrings": {
    "DefaultConnection": "Server=(localdb)\mssqllocaldb;Database=aspnet-ids-3D54E4B2-38C1-466C-A12F-E9CCF493B11B;Trusted_Connection=True;MultipleActiveResultSets=true"
  },

最后生成编译，

生成数据库映射表

更新数据库

dotnet build
dotnet ef migrations add Initial -o Data/Migrations
dotnet ef database update
