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

1. 我有单独的项目

   • 门户网站
   • Portal.ApplicationCore
   • Portal.Infrastructure
   • Portal.Domain

2. 在 Portal.Domain 中，我继承了身份模型

    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; }
     }
   

3. 在 Portal.Infrastructure 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-

严重性代码描述项目文件行抑制状态 错误 CS0311 类型“Portal.Infrastructure.DAL.DatabaseContext.ApplicationDbContext”不能用作泛型类型或方法“IdentityServerBuilderConfigurationExtensions.AddApiAuthorization(IIdentityServerBuilder)”中的类型参数“TContext”。没有从“Portal.Infrastructure.DAL.DatabaseContext.ApplicationDbContext”到“IdentityServer4.EntityFramework.Interfaces.IPersistedGrantDbContext”的隐式引用转换。

谁能帮帮我？

最后，我解决了我的问题。我会把它贴在这里，它可能对某人有帮助。

1. 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)
       {
       }
   }
   

2. 更改数据库上下文

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

3. 最后，修改startup.cs

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