AddApiAuthorization 无隐式引用转换 ASP Core 3.0

Question

尝试在 ASP.NET Core 3.1 中实现 Identity。在解决这个问题时遇到了一些问题。

这是我的设置

我有单独的项目
- 门户网站
- Portal.ApplicationCore
- Portal.Infrastructure
- Portal.Domain

在Portal.Domain我继承了Identity模型

 public class AppRole : IdentityRole<int>
 {
       [Required]
       public int OrganizationID { get; set; }

       [Required(ErrorMessage = "Display name is Required.")]
       [MaxLength(100, ErrorMessage = "Please enter Display name less than 100 characters.")]
       public string DisplayName { get; set; }

       [ForeignKey("OrganizationID")]
       public Organization Organization { get; set; }
  }

  public class AppUser : IdentityUser<int>
  {
       [Required]
       public int OrganizationID { get; set; }

       [ForeignKey("OrganizationID")]
       public Organization Organization { get; set; }
  }

在Portal.Infrastructure中我实现了DBContext

  public class ApplicationDbContext : IdentityDbContext<AppUser, AppRole, int>
  {
         private IDbContextTransaction _transaction;
         public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
          : base(options)
         {
         }

         public DbSet<Organization> Organizations { get; set; }


    }

终于在我的Startup.cs弹出错误-

Severity Code Description Project File Line Suppression State Error CS0311 The type 'Portal.Infrastructure.DAL.DatabaseContext.ApplicationDbContext' cannot be used as type parameter 'TContext' in the generic type or method 'IdentityServerBuilderConfigurationExtensions.AddApiAuthorization(IIdentityServerBuilder)'. There is no implicit reference conversion from 'Portal.Infrastructure.DAL.DatabaseContext.ApplicationDbContext' to 'IdentityServer4.EntityFramework.Interfaces.IPersistedGrantDbContext'.

谁能帮帮我？

终于解决了我的问题。我将 post 放在这里，它可能对某些人有所帮助。

我创建自定义 ApiAuthorizationDbContext

/// <summary>
/// Database abstraction for a combined <see cref="DbContext"/> using ASP.NET 
///Identity and Identity Server.
/// </summary>
/// <typeparam name="TUser"></typeparam>
/// <typeparam name="TRole"></typeparam>
/// <typeparam name="TKey">Key of the IdentityUser entity</typeparam>
public class KeyApiAuthorizationDbContext<TUser, TRole, TKey> : 
IdentityDbContext<TUser, TRole, TKey>, IPersistedGrantDbContext
where TUser : IdentityUser<TKey>
where TRole : IdentityRole<TKey>
where TKey : IEquatable<TKey>
{
    private readonly IOptions<OperationalStoreOptions> _operationalStoreOptions;

    /// <summary>
    /// Initializes a new instance of <see cref="ApiAuthorizationDbContext{TUser, 
    ///TRole, TKey}"/>.
    /// </summary>
    /// <param name="options">The <see cref="DbContextOptions"/>.</param>
    /// <param name="operationalStoreOptions">The <see 
    ///cref="IOptions{OperationalStoreOptions}"/>.</param>
    public KeyApiAuthorizationDbContext(
    DbContextOptions options,
    IOptions<OperationalStoreOptions> operationalStoreOptions)
    : base(options)
    {
        _operationalStoreOptions = operationalStoreOptions;
    }

    /// <summary>
    /// Gets or sets the <see cref="DbSet{PersistedGrant}"/>.
    /// </summary>
    public DbSet<PersistedGrant> PersistedGrants { get; set; }

    /// <summary>
    /// Gets or sets the <see cref="DbSet{DeviceFlowCodes}"/>.
    /// </summary>
    public DbSet<DeviceFlowCodes> DeviceFlowCodes { get; set; }

    Task<int> IPersistedGrantDbContext.SaveChangesAsync() => 
            base.SaveChangesAsync();

    /// <inheritdoc />
    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);
        builder.ConfigurePersistedGrantContext(_operationalStoreOptions.Value);
    }
}

/// <summary>
/// Database abstraction for a combined <see cref="DbContext"/> using ASP.NET 
///Identity and Identity Server.
/// </summary>
/// <typeparam name="TUser"></typeparam>
public class ApiAuthorizationDbContext<TUser> : 
KeyApiAuthorizationDbContext<TUser, IdentityRole, string>
where TUser : IdentityUser
{
    /// <summary>
    /// Initializes a new instance of <see 
    ///cref="ApiAuthorizationDbContext{TUser}"/>.
    /// </summary>
    /// <param name="options">The <see cref="DbContextOptions"/>.</param>
    /// <param name="operationalStoreOptions">The <see 
    ///cref="IOptions{OperationalStoreOptions}"/>.</param>
    public ApiAuthorizationDbContext(
    DbContextOptions options,
    IOptions<OperationalStoreOptions> operationalStoreOptions)
    : base(options, operationalStoreOptions)
    {
    }
}

更改 DbContext

public class ApplicationDbContext : KeyApiAuthorizationDbContext<AppUser, AppRole, 
int>
{
    public ApplicationDbContext(
        DbContextOptions options,
        IOptions<OperationalStoreOptions> operationalStoreOptions) : base(options, 
        operationalStoreOptions)
    {
    }
    public DbSet<Organization> Organizations { get; set; }
}

最后，改startup.cs

services.AddIdentityServer()                
    .AddApiAuthorization<AppUser, ApplicationDbContext>();
