.Net6集成IdentityServer4 +AspNetCore Identity读取本地数据表用户 独立鉴权授权管理API

2023-03-31 11:00:24 时间

IdentityServer4 实现鉴权、授权，AspNetCore Identity实现数据库用户管理表直接生成。

ps：IdentityServer4文档上最后给的例子是 // 配置使用内存存储用户信息，但使用 EF 存储客户端和资源信息，

　　我初步要实现的是 //数据库存储用户信息   内存存储资源   （下一步资源也放数据库  以后弄好了有机会更）

直接干活：

1.创建.Net6 API程序，一顿引用，包括

防止图片挂掉打一遍文字：

IdentityServer4、

IdengtityServer4.AspNetIdentity、

AspNetCore.Identity.EntityFrameWorkCore（生成数据库表用的）、

EntityFrameWork+Disign+Tool三件套 (缺了不能自动迁移)、

Pomelo.EntityFrameWorkCore.MySql(我是用的MySql，如果是SqlServer 不用这个用一个大概叫EF.Sqlserver的)、

Encrypt (加密MD5用的 不必须)、

下面那个是自带的。

2.建立数据库连接类

 1  public class IdpDbContext : IdentityDbContext<ApplicationUser>
 2     {
 3         public IdpDbContext(DbContextOptions<IdpDbContext> opt) : base(opt)
 4         {
 5 
 6         }
 7         protected override void OnModelCreating(ModelBuilder builder)
 8         {
 9             base.OnModelCreating(builder);
10             builder.Entity<ApplicationUser>().ToTable("ApplicationUsers");
11             #region #
12             //builder.Entity<IdentityUserLogin<string>>().ToTable("ApplicationLogins");
13             //builder.Entity<IdentityUserClaim<string>>().ToTable("ApplicationUserClaims");
14             //builder.Entity<ApplicationUserRole>().ToTable("ApplicationUserRoles");

3.Program里开始加东西（如果是历史的Net版本，是在StartUp里）：

直接代码

 1 using Microsoft.AspNetCore.Identity;
 2 using Microsoft.EntityFrameworkCore;
 3 using MyIDP;
 4 using MyIDP.Models;
 5 using MyIDP.Permission;
 6 
 7 var builder = WebApplication.CreateBuilder(args);
 8 
 9 // Add services to the container.
10 builder.Services.AddControllers();
11 // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
12 builder.Services.AddEndpointsApiExplorer();
13 builder.Services.AddSwaggerGen();
14 
15 //由此重要
16 builder.Services.AddDbContext<IdpDbContext>(opt =>
17 {
18     opt.UseMySql("server=127.0.0.1;Port=3306;database=AccountDb;uid=root;pwd=123456;", new MySqlServerVersion(new Version(8,0,29)));
19 });
20 
21 builder.Services.AddIdentity<ApplicationUser, IdentityRole>()
22                 .AddUserManager<MyUserManager>()
23                 .AddEntityFrameworkStores<IdpDbContext>()
24                 .AddDefaultTokenProviders();
25 
26 builder.Services.AddIdentityServer()
27     .AddDeveloperSigningCredential()
28 
29     .AddInMemoryIdentityResources(MyIDP.IdpConfig.GetIdentityResources())
30     .AddInMemoryClients(MyIDP.IdpConfig.GetClients())

45     //        }
46     //    }
47     //})
48     ;
49 
50 var app = builder.Build();
51 
52 // Configure the HTTP request pipeline.
53 if (app.Environment.IsDevelopment())
54 {
55     app.UseSwagger();
56     app.UseSwaggerUI();
57 }
58 
59 app.UseIdentityServer();
