Data Protection.Entity Framework 引发 Postgresql 异常

Question

我对 Postgresql 数据库也有同样的问题。为了管理迁移，我使用的是 EF。尝试向应用程序添加迁移时，我收到了这个奇怪的问题。在我开始使用 SQL Server 之前，我从来没有遇到过这个问题。

System.Security.Cryptography.CryptographicException: An error occurred while trying to encrypt the provided data. Refer to the inner exception for more information.

我在用：

1. .net 核心 3.1
2. EF 3.1.13
3. Microsoft.AspNetCore.DataProtection.EntityFramework 3.1.13
4. Npgsql.EntityFrameworkCore.PostgreSQL 3.1.11

   我的应用程序数据库上下文有这个定义

   ....
    public DbSet<DataProtectionKey> DataProtectionKeys { get; set; }
    public DbSet<DataAudit> AuditTrail { get; set; }
    public DbSet<Settings> Settings { get; set; }
    public DbSet<ApiResourceEntity> ApiResources { get; set; }
   ....
   

   DbContext 定义

   serviceCollection.AddDataProtection()
                   .SetApplicationName("MyAPP")
                   .PersistKeysToDbContext<ApplicationDbContext>()
                   .ProtectKeysWithDpapiNG();
   

   编辑：我评论了这段代码并且迁移已经通过，所以问题是 OnModelCreating(ModelBuilder modelBuilder) 方法上的这段代码：

    foreach (var entityType in modelBuilder.Model.GetEntityTypes())
               {
                   foreach (var property in entityType.GetProperties())
                   {
                       var attributes = property.PropertyInfo.GetCustomAttributes(typeof(EncryptedAttribute), false);
                       if (attributes.Any())
                       {
                           property.SetValueConverter(new EncryptedConverter(_dataProtectionProvider));
                       }
                   }
               }
   

   任何想法都会有所帮助。 问候

首先，您需要运行 Skoruba project.Identity Server 4.Admin。他将推出迁移。然后才启动 Skoruba.Identity Server 4.STS.Identity！你可能正在做相反的事情......
