entity-framework - 如何更改表的 Identity Server 4 架构？

Question

默认情况下，Identity Server 4 的表架构是 dbo，我想将其更改为安全性，因此我创建了继承自 ConfigurationDbContext 的 ConfigurationContext >:

 public class ConfigurationContext : ConfigurationDbContext
 {
    public ConfigurationContext(DbContextOptions<ConfigurationDbContext> options, ConfigurationStoreOptions storeOptions) : base(options, storeOptions)
    { }


    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        modelBuilder.HasDefaultSchema("Security");
    }
    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        var relationalOptions = RelationalOptionsExtension.Extract(optionsBuilder.Options);
        relationalOptions.MigrationsHistoryTableSchema = "Security";
    }

  }

在 add-migration 中我使用 ConfigurationContext :

Add-Migration -c ConfigurationContext

但是我得到了这个错误:

No parameterless constructor was found on 'ConfigurationContext'. Either add a parameterless constructor to 'ConfigurationContext' or add an implementation of 'IDbContextFactory' in the same assembly as 'ConfigurationContext'.

问题是什么？

Answer 1

IdentityServer4 提供了这个选项。在 ConfigureServices 中，

services.AddIdentityServer()
.AddOperationalStore(builder => builder.UseSqlServer(cnStr, options =>
                        options.MigrationsAssembly(migAssembly)),
                        storeOption => storeOption.DefaultSchema = "security")

这样，您就可以按照快速入门中的建议继续使用 IDbContextFactory。
