identityserver4 - Identityserver4 中的 ConfigurationDbContext 可以使用扩展吗？

Question

ConfigurationDbContext 是否有可用的扩展，我们可以在使用 IdentityServer4 时为任何其他字段或索引自定义上下文？

是否可以扩展 IdentityServer4 提供的模型？

Answer 1

我猜你问的是如何自定义 EntityFramework.DbContexts.Config

你可以从下面的代码中得到一些启发

public class CustomConfigurationContextFactory : IDbContextFactory<CustomConfigurationDbContext>
{
    /// <summary>
    /// A factory to create an instance of the StudentsContext 
    /// </summary>
    /// <param name="connectionString"></param>
    /// <returns></returns>
    public static CustomConfigurationDbContext Create(string connectionString)
    {
        var optionsBuilder = new DbContextOptionsBuilder<ConfigurationDbContext>();

        optionsBuilder.UseSqlServer(connectionString);

        var context = new CustomConfigurationDbContext(
            optionsBuilder.Options, 
            new ConfigurationStoreOptions());
        context.Database.EnsureCreated();

        return context;
    }

    public CustomConfigurationDbContext Create(DbContextFactoryOptions options)
    {
        var context = new CustomConfigurationDbContext(
            new DbContextOptions<ConfigurationDbContext>(),
            new ConfigurationStoreOptions() 
          );

        context.Database.EnsureCreated();

        return context;
    }
    protected override void OnModelCreating(ModelBuilder builder)
    {
        builder.ConfigureClientContext(_storeOptions);
        builder.Entity<Client>().HasIndex(x => x.ClientName).IsUnique();
    }
}

public class CustomConfigurationContextFactory : IDbContextFactory<CustomConfigurationDbContext>
{
    public CustomConfigurationDbContext Create(DbContextFactoryOptions options)
    {
        var context = new CustomConfigurationDbContext(
            new DbContextOptions<ConfigurationDbContext>(),
            new ConfigurationStoreOptions() 
          );

        context.Database.EnsureCreated();

        return context;
    }
}

OnModelCreating 您可以添加索引，也可以将自定义 Dbset 添加到自定义配置 dbcontext
