<十一>将identityserver4的一些权限配置持久化到数据库

刚开始为了方便，我们把配置写在一个config的类里面了，用内存加载的方式加载进去。

下面我们把这些配置持久化到数据库。

引入 IDentityserver4.EntityFrameWork 的nuget包。

然后修改部分startup的部分配置。

  public void ConfigureServices(IServiceCollection services)
        {
            string connectionstring = Configuration.GetConnectionString("IdentityServer4Conn");
            var migrationsAssembly=  typeof(Startup).Assembly.GetName().Name;
            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });

            services.AddDbContext<ApplicationDbContext>(options =>
            {
                options.UseSqlServer(Configuration.GetConnectionString("IdentityConn"));
            });

            //配置Identity
            services.AddIdentity<ApplicationUser, ApplicationUserRoles>()
                .AddEntityFrameworkStores<ApplicationDbContext>()
                .AddDefaultTokenProviders();
            //修改Identity密码强度设置配置
            services.Configure<IdentityOptions>(options =>
            {
                options.Password.RequireLowercase = false; //需要小写
                options.Password.RequireNonAlphanumeric = false; //需要字母
                options.Password.RequireUppercase = false; //需要大写
                options.Password.RequiredLength = 6;
            });
            //IdentityServer4.EntityFramework.DbContexts.ConfigurationDbContext
            // IdentityServer4.EntityFramework.DbContexts.PersistedGrantDbContext
            services.AddIdentityServer().AddDeveloperSigningCredential()
               // .AddInMemoryApiResources(Config.GetApiResources())
              //  .AddInMemoryApiScopes(Config.GetScopes())
              //  .AddInMemoryClients(Config.GetClients())
                // .AddTestUsers(Config.GetUsers().ToList())
                .AddAspNetIdentity<ApplicationUser>()
              //  .AddInMemoryIdentityResources(Config.GetIdentityResources())
                //添加client配置
                 .AddConfigurationStore(options =>
                 {
                     options.ConfigureDbContext = builder => { builder.UseSqlServer(connectionstring, sql => sql.MigrationsAssembly(migrationsAssembly)); };
                 })
                // this adds the operational data from DB (codes, tokens, consents)
                //添加resource scopes等配置
                .AddOperationalStore(options =>
                {
                    options.ConfigureDbContext = b =>
                        b.UseSqlServer(connectionstring,
                            sql => sql.MigrationsAssembly(migrationsAssembly));

                    // this enables automatic token cleanup. this is optional.
                    options.EnableTokenCleanup = true;
                });

            services.AddControllersWithViews();
        }

appsetting.json中添加新的数据库链接配置

  "ConnectionStrings": {
    "IdentityConn": "Data Source=127.0.0.1;User ID=sa;Password=62;database=IdentityTest;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False",
    "IdentityServer4Conn": "Data Source=127.0.0.1;User ID=sa;Password=62;database=IdentityServer4Test;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False"

  }

配置完成后用add-migration 命令试一下，发生如下错误

<十一>将identityserver4的一些权限配置持久化到数据库

说要使用指定的Dbcontext,IdentityServer4.EntityFrameWork里面有两个context需要我们初始化

 IdentityServer4.EntityFramework.DbContexts.ConfigurationDbContext  
 IdentityServer4.EntityFramework.DbContexts.PersistedGrantDbContext

由于上次我们给Identity 做过持久化，那么migration的存放位置需要就不能用Data了，我们给指定在Data下面的自文件夹下，命令如下

add-migration init -Context ConfigurationDbContext -OutputDir Data/Migrations/IdentityServer4/configurationDbContext

add-migration init -Context PersistedGrantDbContext -OutputDir Data/Migrations/IdentityServer4/persistedGrantDbContext

update-database -Context ConfigurationDbContext

update-database -Context PersistedGrantDbContext

看下生成的migration的放置位置和数据库生成的表

这样持久化就完成了，那么我们尝试着来给数据表初始化一些数据。

利用Identityserver4.EntityframeWork.Mapper 这个映射工具，将我们在config中的配置映射并初始化到数据库中去，在startup中的configure函数中运行此方法。

  public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }

            InitializeDatabase(app);

            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseIdentityServer();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }

 
private void InitializeDatabase(IApplicationBuilder app)
        {
            using (var serviceScope = app.ApplicationServices.GetService<IServiceScopeFactory>().CreateScope())
            {
                serviceScope.ServiceProvider.GetRequiredService<PersistedGrantDbContext>().Database.Migrate();

                var context = serviceScope.ServiceProvider.GetRequiredService<ConfigurationDbContext>();
                context.Database.Migrate();
                if (!context.Clients.Any())
                {
                    foreach (var client in Config.GetClients())
                    {
                        context.Clients.Add(client.ToEntity());
                    }
                    context.SaveChanges();
                }

                if (!context.IdentityResources.Any())
                {
                    foreach (var identityResource in Config.GetIdentityResources())
                    {
                        context.IdentityResources.Add(identityResource.ToEntity());
                    }
                    context.SaveChanges();
                }

                if (!context.ApiResources.Any())
                {
                    foreach (var apiResource in Config.GetApiResources())
                    {
                        context.ApiResources.Add(apiResource.ToEntity());
                    }
                    context.SaveChanges();
                }

                if (!context.ApiScopes.Any())
                {
                    foreach (var scope in Config.GetScopes())
                    {
                        context.ApiScopes.Add(scope.ToEntity());
                    }
                    context.SaveChanges();
                }

            }
        }

开启服务端和客户端，将登陆逻辑走一遍，走通就可以了。
