IdentityServer4 數據庫遷移問題

Question

我正在使用 .net 核心 3.1 構建 identityserver4。 我正在使用數據庫遷移來構建數據庫。 我遇到的問題是播種方法。 我的播種方法如下：

private void ClientSeed(ModelBuilder builder)
        {
            builder.Entity<ApiResource>()
               .HasData(
                   new ApiResource
                   {
                       Name = "PatientPortalAPI",
                       DisplayName = "Patient Portal API",

                       ApiSecrets =
                       {
                           new Secret("secret".Sha256())
                       },

                       Scopes =
                       {
                           new Scope()
                           {
                                 Name = StandardScopes.OfflineAccess,
                                 DisplayName = StandardScopes.OfflineAccess,
                                 Description = null,
                                 Required = false,
                                 Emphasize = false,
                                 ShowInDiscoveryDocument = true,
                           },
                           new Scope()
                           {
                                 Name = StandardScopes.OpenId,
                                 DisplayName = StandardScopes.OpenId,
                                 Description = null,
                                 Required = false,
                                 Emphasize = false,
                                 ShowInDiscoveryDocument = true,
                           }
                       }
                   }
               );

            builder.Entity<IdentityResource>().HasData(
                    new IdentityResource()
                    {
                        Enabled = true,
                        Name = "openid",
                        DisplayName = "Your user identifier",
                        Description = null,
                        Required = true,
                        Emphasize = false,
                        ShowInDiscoveryDocument = true,
                    },
                    new IdentityResource()
                    {
                        Enabled = true,
                        Name = "profile",
                        DisplayName = "User profile",
                        Description = "Your user profile information (first name, last name, etc.)",
                        Required = false,
                        Emphasize = true,
                        ShowInDiscoveryDocument = true,
                    });

            builder.Entity<Client>()
                .HasData(
                    new Client
                    {
                        ClientId = "t8agr5xKt4$3",
                        AllowedGrantTypes = GrantTypes.ResourceOwnerPassword,

                        ClientSecrets =
                        {
                            new Secret("secret".Sha256())
                        },

                        AllowedScopes =
                        {
                            StandardScopes.OpenId,
                            StandardScopes.Profile,
                            StandardScopes.Email,
                            StandardScopes.Address,
                            "api1",
                            StandardScopes.OfflineAccess
                        },

                        AllowOfflineAccess = true,
                        RefreshTokenUsage = TokenUsage.ReUse,
                        RefreshTokenExpiration = TokenExpiration.Sliding,
                    });
        }

添加遷移時出現的錯誤是：

System.InvalidOperationException: No suitable constructor found for entity type 'Claim'. The following constructors had parameters that could not be bound to properties of the entity type: cannot bind 'reader' in 'Claim(BinaryReader reader)'; cannot bind 'reader', 'subject' in 'Claim(BinaryReader reader, ClaimsIdentity subject)'; cannot bind 'type', 'value' in 'Claim(string type, string value)'; cannot bind 'type', 'value', 'valueType' in 'Claim(string type, string value, string valueType)'; cannot bind 'type', 'value', 'valueType', 'issuer' in 'Claim(string type, string value, string valueType, string issuer)'; cannot bind 'type', 'value', 'valueType', 'issuer', 'originalIssuer' in 'Claim(string type, string value, string valueType, string issuer, string originalIssuer)'; cannot bind 'type', 'value', 'valueType', 'issuer', 'originalIssuer', 'subject' in 'Claim(string type, string value, string valueType, string issuer, string originalIssuer, ClaimsIdentity subject)'; cannot bind 'type', 'value', 'valueType', 'issuer', 'originalIssuer', 'subject', 'propertyKey', 'propertyValue' in 'Claim(string type, string value, string valueType, string issuer, string originalIssuer, ClaimsIdentity subject, string propertyKey, string propertyValue)'; cannot bind 'other' in 'Claim(Claim other)'; cannot bind 'other', 'subject' in 'Claim(Claim other, ClaimsIdentity subject)'.

排除上述種子方法，數據庫遷移工作得非常好。 一旦我在 ConfigurationDbContext class 的 OnModelCreating 方法中調用播種方法，它就會因上述錯誤而失敗。

誰能在這里發現我哪里出錯了？？？

我將期待您的所有回復。

提前致謝，

Answer 1

您應該在IdentityServer4.EntityFramework.Entities上使用類型，您在代碼中混合了模型和實體，嘗試using IdentityServer4.Models; 清楚地了解什么是實體，什么是 model。 正確使用實體后，您將看到例如ApiResource沒有ApiSecrets屬性，它是Secrets 。

還有另一種方法可以通過添加方法 ob startup.cs來初始化數據庫，例如：

private void InitializeDatabase(IApplicationBuilder app)
{
    using (var serviceScope = app.ApplicationServices.GetService<IServiceScopeFactory>().CreateScope())
    {
        serviceScope.ServiceProvider.GetRequiredService<PersistedGrantDbContext>().Database.Migrate();

        var context = serviceScope.ServiceProvider.GetRequiredService<ConfigurationDbContext>();
        context.Database.Migrate();
        if (!context.Clients.Any())
        {
            foreach (var client in Config.Clients)
            {
                context.Clients.Add(client.ToEntity());
            }
            context.SaveChanges();
        }

        if (!context.IdentityResources.Any())
        {
            foreach (var resource in Config.Ids)
            {
                context.IdentityResources.Add(resource.ToEntity());
            }
            context.SaveChanges();
        }

        if (!context.ApiResources.Any())
        {
            foreach (var resource in Config.Apis)
            {
                context.ApiResources.Add(resource.ToEntity());
            }
            context.SaveChanges();
        }
    }
}

並這樣稱呼它；

public void Configure(IApplicationBuilder app)
{
    // this will do the initial DB population
    InitializeDatabase(app);

    // the rest of the code that was already here
    // ...
}
