.Net6集成IdentityServer4?+AspNetCore?Identity讀取數據表用戶且鑒權授權管理API_實用技巧

作者：螺絲起子 ? 更新時間： 2022-09-12 編程語言

前言

IdentityServer4 實現鑒權、授權，AspNetCore Identity實現數據庫用戶管理表直接生成。

ps：IdentityServer4文檔上最后給的例子是?// 配置使用內存存儲用戶信息，但使用 EF 存儲客戶端和資源信息，

我初步要實現的是 //數據庫存儲用戶信息? ?內存存儲資源? ?（下一步資源也放數據庫? 以后弄好了有機會更）

1.創(chuàng)建.Net6 API程序

一頓引用，包括

防止圖片掛掉打一遍文字：

  • IdentityServer4、
  • IdengtityServer4.AspNetIdentity、
  • AspNetCore.Identity.EntityFrameWorkCore（生成數據庫表用的）、
  • EntityFrameWork+Disign+Tool三件套 (缺了不能自動遷移)、
  • Pomelo.EntityFrameWorkCore.MySql(我是用的MySql，如果是SqlServer 不用這個用一個大概叫EF.Sqlserver的)、
  • Encrypt (加密MD5用的 不必須)、

下面那個是自帶的。

2.建立數據庫連接類

using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;
using MyIDP;
using MyIDP.Models;
using MyIDP.Permission;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

//由此重要
builder.Services.AddDbContext<IdpDbContext>(opt =>
{
    opt.UseMySql("server=127.0.0.1;Port=3306;database=AccountDb;uid=root;pwd=123456;", new MySqlServerVersion(new Version(8,0,29)));
});

builder.Services.AddIdentity<ApplicationUser, IdentityRole>()
                .AddUserManager<MyUserManager>()
                .AddEntityFrameworkStores<IdpDbContext>()
                .AddDefaultTokenProviders();

builder.Services.AddIdentityServer()
    .AddDeveloperSigningCredential()

    .AddInMemoryIdentityResources(MyIDP.IdpConfig.GetIdentityResources())
    .AddInMemoryClients(MyIDP.IdpConfig.GetClients())
    .AddInMemoryApiScopes( MyIDP.IdpConfig.GetScope())
    .AddInMemoryApiResources( MyIDP.IdpConfig.GetApiResources())    //.AddResourceOwnerValidator<MyResourceOwnerPasswordValidator>() //這句可以打開自主驗證登錄用戶
    //.AddProfileService<MyProfileService>()
    .AddAspNetIdentity<ApplicationUser>()
    //.AddTestUsers(new List<IdentityServer4.Test.TestUser>
    //{
    //    new IdentityServer4.Test.TestUser
    //    {
    //        SubjectId="123",
    //        Username = "alice",
    //        Password = "alice",
    //        Claims = new List<Claim>() {
    //            new Claim(JwtClaimTypes.Role, "superadmin"),
    //            new Claim(JwtClaimTypes.Role, "admin")
    //        }
    //    }
    //})
    ;

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseIdentityServer();
app.UseAuthorization();
app.MapControllers();
app.Run();

3.Program里開始加東西（如果是歷史的Net版本，是在StartUp里）

using Microsoft.AspNetCore.Identity;
using Microsoft.EntityFrameworkCore;
using MyIDP;
using MyIDP.Models;
using MyIDP.Permission;

var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
//由此重要
builder.Services.AddDbContext<IdpDbContext>(opt =>
{
    opt.UseMySql("server=127.0.0.1;Port=3306;database=AccountDb;uid=root;pwd=123456;", new MySqlServerVersion(new Version(8,0,29)));
});
builder.Services.AddIdentity<ApplicationUser, IdentityRole>()
                .AddUserManager<MyUserManager>()
                .AddEntityFrameworkStores<IdpDbContext>()
                .AddDefaultTokenProviders();
builder.Services.AddIdentityServer()
    .AddDeveloperSigningCredential()
    .AddInMemoryIdentityResources(MyIDP.IdpConfig.GetIdentityResources())
    .AddInMemoryClients(MyIDP.IdpConfig.GetClients())
    .AddInMemoryApiScopes( MyIDP.IdpConfig.GetScope())
    .AddInMemoryApiResources( MyIDP.IdpConfig.GetApiResources())    //.AddResourceOwnerValidator<MyResourceOwnerPasswordValidator>() //這句可以打開自主驗證登錄用戶
    //.AddProfileService<MyProfileService>()
    .AddAspNetIdentity<ApplicationUser>()
    //.AddTestUsers(new List<IdentityServer4.Test.TestUser>
    //{
    //    new IdentityServer4.Test.TestUser
    //    {
    //        SubjectId="123",
    //        Username = "alice",
    //        Password = "alice",
    //        Claims = new List<Claim>() {
    //            new Claim(JwtClaimTypes.Role, "superadmin"),
    //            new Claim(JwtClaimTypes.Role, "admin")
    //        }
    //    }
    //})
    ;
var app = builder.Build();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}
app.UseIdentityServer();
app.UseAuthorization();
app.MapControllers();
app.Run();

因為使用的是內存儲存t鑒權信息的方式，所以建立IdentityServer4的配置類IdpConfig

public static class IdpConfig
    {
        public static IEnumerable<IdentityResource> GetIdentityResources()
        {
            return new IdentityResource[]
            {
                new IdentityResources.OpenId(),
                new IdentityResources.Profile(),
                new IdentityResources.Address(),
                new IdentityResources.Phone(),
                new IdentityResources.Email()
            };
        }
        public static IEnumerable<ApiResource> GetApiResources()
        {
            //return new ApiResource[]
            //{
            //    new ApiResource("api1", "My API #1",new List<string>(){JwtClaimTypes.Role})
            //};
            //新寫法
            return new[]
            {
                new ApiResource("api1", "My API #1")
                {
                    Scopes = { "scope1"}
                }
            };
        }
        public static IEnumerable<Client> GetClients()
        {
            return new[]
            {
                #region MyRegion
                 //// client credentials flow client
                //new Client
                //{
                //    ClientId = "console client",
                //    ClientName = "Client Credentials Client",

                //    AllowedGrantTypes = GrantTypes.ClientCredentials,

                //    ClientSecrets = { new Secret("511536EF-F270-4058-80CA-1C89C192F69A".Sha256()) },

                //    AllowedScopes = { "api1" }
                //},

    #endregion
                // wpf client, password grant
                new Client
                {
                    ClientId = "client",
                    AllowedGrantTypes = GrantTypes.ResourceOwnerPassword,
                    ClientSecrets =
                    {
                        new Secret("secret".Sha256())
                    },
                    AllowedScopes = //允許當訪問的資源
                    {
                        "scope1",
                        //"api1",
                        IdentityServerConstants.StandardScopes.OpenId,
                        IdentityServerConstants.StandardScopes.Email,
                        IdentityServerConstants.StandardScopes.Address,
                        IdentityServerConstants.StandardScopes.Phone,
                        IdentityServerConstants.StandardScopes.Profile }
                }
            };
        }
        public static IEnumerable<ApiScope> GetScope()
        {
            return new ApiScope[] {
                new ApiScope("scope1"),
                new ApiScope("scope2"),
            };
        }
    }

數據庫的usernamager

public class MyUserManager : UserManager<ApplicationUser>
    {
        public MyUserManager(IUserStore<ApplicationUser> store, IOptions<IdentityOptions> optionsAccessor, IPasswordHasher<ApplicationUser> passwordHasher,
          IEnumerable<IUserValidator<ApplicationUser>> userValidators, IEnumerable<IPasswordValidator<ApplicationUser>> passwordValidators, ILookupNormalizer keyNormalizer, IdentityErrorDescriber errors, IServiceProvider services, ILogger<UserManager<ApplicationUser>> logger)
           : base(store, optionsAccessor, new MyPasswordHasher(), userValidators, passwordValidators, keyNormalizer, errors, services, logger)
        {
            optionsAccessor.Value.Password.RequireDigit = false;
            optionsAccessor.Value.Password.RequiredLength = 4;
            optionsAccessor.Value.Password.RequireLowercase = false;
            optionsAccessor.Value.Password.RequireUppercase = false;
            optionsAccessor.Value.Password.RequireNonAlphanumeric = false;
        }

    }

重寫驗證密碼的方法類MyResourceOwnerPasswordValidator，（如果沒有打開Program中的AddResourceOwnerValidator<MyResourceOwnerPasswordValidator>() 則不需要）

public class MyResourceOwnerPasswordValidator : IResourceOwnerPasswordValidator
    {
        public readonly SignInManager<ApplicationUser> signInManager;
        private readonly MyUserManager userManager;
        //public readonly IEventService service;
        public MyResourceOwnerPasswordValidator(MyUserManager userService, SignInManager<ApplicationUser> signInManager)//, IEventService service)
        {
            userManager = userService;
            this.signInManager = signInManager;
            //this.service = service;
        }
        public async Task ValidateAsync(ResourceOwnerPasswordValidationContext context)
        {
            if (string.IsNullOrEmpty(context.UserName) || string.IsNullOrEmpty(context.Password))
            {
                context.Result = new GrantValidationResult(TokenRequestErrors.InvalidGrant, "驗證被拒絕，用戶名或者密碼為空。");
                return;
            }
            var user = await userManager.FindByNameAsync(context.UserName);
            if (user == null)
            {
                context.Result = new GrantValidationResult(TokenRequestErrors.InvalidGrant, "驗證失敗，不存在當前用戶。");
                return;
            }
            //檢驗用戶密碼（雖然我也不知道他的密碼是采用什么加密方式得到的，但是我也不需要知道） 
            var passwordPass = await userManager.CheckPasswordAsync(user, context.Password);
            if (!passwordPass)
            {
                context.Result = new GrantValidationResult(TokenRequestErrors.InvalidGrant, "驗證失敗，用戶憑證錯誤");
                return;
            }
            else
            {
                try
                {
                    await userManager.AddLoginAsync(user, new UserLoginInfo(user.Id, "", user.UserName));
                }
                catch (Exception ex)
                {
                    ;
                }
                finally
                {
                    context.Result = new GrantValidationResult(user.Id, GrantType.ResourceOwnerPassword, new List<Claim>() { new Claim("account", user.UserName) }); 
                }
            }
            return;
        }
    }

MyPasswordHasher

public class MyPasswordHasher : PasswordHasher<ApplicationUser>
    {
        public override string HashPassword(ApplicationUser user, string password)
        {
            //PasswordHasher<ApplicationUser> ph = new PasswordHasher<ApplicationUser>();
            //var pstr = ph.HashPassword(new ApplicationUser(), password);
            //return pstr;
            return password.MD5();
        }

        public override PasswordVerificationResult VerifyHashedPassword(ApplicationUser user, string hashedPassword, string providedPassword)
        {
            if (providedPassword.MD5().Equals(hashedPassword))
            {
                return PasswordVerificationResult.Success;
            }
            else
            {
                return PasswordVerificationResult.Failed;
            }
        }
    }

創(chuàng)建自己的User類?ApplicationUser繼承?IdentityUser? 復寫自帶的AspNetUser表

public class ApplicationUser : IdentityUser
    {
        public string MySomething { get; set; } = "";
        /// <summary>
        /// 創(chuàng)建時間
        /// </summary>
        public DateTime CreateTime { get; set; }
        /// <summary>
        /// 創(chuàng)建人Id
        /// </summary>
        public string CreatorId { get; set; } = "";
        /// <summary>
        /// 否已刪除
        /// </summary>
        public bool Deleted { get; set; }
        /// <summary>
        /// 姓名
        /// </summary>
        public string RealName { get; set; }
        /// <summary>
        /// 性別
        /// </summary>
        public Sex Sex { get; set; }
        /// <summary>
        /// 出生日期
        /// </summary>
        public DateTime? Birthday { get; set; }
        /// <summary>
        /// 所屬部門Id
        /// </summary>
        public string DepartmentId { get; set; } = "";
        public string OtherData { get; set; } = "";
        // 用戶角色 用戶權限 用戶信息 用戶登錄tokens  重新綁定與父類的關系 命名必須和父類一致
        public virtual ICollection<IdentityUserRole<string>> UserRoles { get; set; }
        public virtual ICollection<IdentityUserClaim<string>> Claims { get; set; }
        public virtual ICollection<IdentityUserLogin<string>> Logins { get; set; }
        public virtual ICollection<IdentityUserToken<string>> Tokens { get; set; }
    }
    public enum Sex
    {
        [Description("男")]
        Man = 1,
        [Description("女")]
        Woman = 0
    }

至此可以生成數據庫遷移后 Postman測試一下：
