我正在使用.net core 3.1构建Identityserver4。我正在使用数据库迁移来构建数据库。我遇到的问题是播种方法。我的播种方法如下：
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,
});
}
添加迁移时出现的错误是：
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)'.

不包括上述播种方法，数据库迁移确实运行良好。我在ConfigurationDbContext类的OnModelCreating方法中调用种子方法后，它立即失败，并显示上述错误。
谁能在这里发现我要去哪里错了吗？
我期待您的所有答复。
谢谢，

您应该在IdentityServer4.EntityFramework.Entities上使用类型，代码中混合了模型和实体，请尝试删除using IdentityServer4.Models;以清楚地了解什么是实体和什么是模型。正确使用实体后，您会看到，例如ApiResource没有作为ApiSecrets的属性，而是Secrets。
还有另一种方法可以通过添加方法ob startup.cs来初始化数据库，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();
}
}
}
并这样称呼；
public void Configure(IApplicationBuilder app)
{
// this will do the initial DB population
InitializeDatabase(app);
// the rest of the code that was already here
// ...
}
