哈喽大家好,看见网上很少有使用MySql进行持久化的,毕竟又很多坑,说句实话,就连 MySql.Data.EntityFrameworkCore 都有问题,不知道是.net core更新太快还是其它的问题,但毕竟mssql驱动是没问题的,感觉还是私心太大了。不得以之下选择了一个第三方的驱动 Pomelo.EntityFrameworkCore.MySql 驱动,在这里主要是你安装了它,你就又了它的设计器,但你还需要你安装EFCore的设计器,因为你执行dotnet命令迁移的时候还得靠它,好吧,我们继续,在你的应用程序中最好保持这几个包。能多不能少。
<ItemGroup>
<PackageReference Include="IdentityServer4" Version="2.0.0-rc1" />
<PackageReference Include="IdentityServer4.AspNetIdentity" Version="2.0.0-rc1" />
<PackageReference Include="IdentityServer4.EntityFramework" Version="2.0.0-rc1" />
<PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" />
<PackageReference Include="Microsoft.EntityFrameworkCore" Version="2.0.0" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="2.0.0" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.0" />
<PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="2.0.0-rtm-10062" />
<PackageReference Include="Pomelo.EntityFrameworkCore.MySql.Design" Version="1.1.2" />
</ItemGroup>
就这样,在Model里创建两个类,一个是用户、一个是关系,这个是Identity的类。其实这个和IdentityServer是没有多大关系的。主要是为了扩展一些东西,比如你需要其它的字段?
public class ApplicationRole : IdentityRole{}
public class ApplicationUser : IdentityUser{}
随后我们定义IdentityDbContext,将我们自己定义的两个类放进去,它是个泛型的。
public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, string>
{
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);
}
}
再之后我们就可以注入到.Net Core的服务里了,IdentityServer的数据库中有三个大类,有AspNet的票据用户、资源的管理、以及一些操作的记录。这里你可以用一个database,你也可以分开。
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddDbContext<ApplicationDbContext>(options =>
options.UseMySql(Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<ApplicationUser, ApplicationRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
services.AddMvc();
string migrationsAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;
services.AddIdentityServer()
.AddConfigurationStore(options =>
{
options.ConfigureDbContext = builder =>
builder.UseMySql(Configuration.GetConnectionString("DefaultConnection"),
sql => sql.MigrationsAssembly(migrationsAssembly));
})
.AddOperationalStore(options =>
{
options.ConfigureDbContext = builder =>
builder.UseMySql(Configuration.GetConnectionString("DefaultConnection"),
sql => sql.MigrationsAssembly(migrationsAssembly));
// this enables automatic token cleanup. this is optional.
options.EnableTokenCleanup = true;
options.TokenCleanupInterval = 30;
});
}
随后注册IdentityServer服务,这个里面调用了 InitializeDatabase 方法为了初始化的迁移数据。
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
InitializeDatabase(app);
if (env.IsDevelopment())
app.UseDeveloperExceptionPage();
else
app.UseExceptionHandler("/Home/Error");
app.UseIdentityServer();
}
这个方法就很有意思了,获取了.net core的服务实例,然后对我的Context进行了更新迁移,直接将Config中的内存数据添加到了数据库中。
private void InitializeDatabase(IApplicationBuilder app)
{
using (var serviceScope = app.ApplicationServices.GetService<IServiceScopeFactory>().CreateScope())
{
serviceScope.ServiceProvider.GetRequiredService<ApplicationDbContext>().Database.Migrate();
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 resource in Config.GetIdentityResources())
{
context.IdentityResources.Add(resource.ToEntity());
}
context.SaveChanges();
}
if (!context.ApiResources.Any())
{
foreach (var resource in Config.GetApiResources())
{
context.ApiResources.Add(resource.ToEntity());
}
context.SaveChanges();
}
}
最后你需要执行三个命令,执行EFCore的数据迁移。
dotnet ef migrations add InitialIdentityServerPersistedGrantDbMigration -c PersistedGrantDbContext -o Data/Migrations/IdentityServer/PersistedGrantDb
dotnet ef migrations add InitialIdentityServerConfigurationDbMigration -c ConfigurationDbContext -o Data/Migrations/IdentityServer/ConfigurationDb
dotnet ef migrations add InitialIdentityServerApplicationDbMigration -c ApplicationDbContext -o Data/Migrations/IdentityServer/ApplicationDb
就这样,生成完毕我们测试一下程序。
Ok,一些正常。
