我已经学习了IdentityServer4一周，并成功实现了一个简单的ResourceOwnedPassword流认证流程。
现在，我正在通过跟随this tutorial在IdentityServer4上实施Google身份验证
这就是我在做的事情：
Startup.cs
public void ConfigureServices(IServiceCollection services)
{
//...
const string connectionString = @"Data Source=.\SQLEXPRESS;database=IdentityServer4.Quickstart.EntityFramework-2.0.0;trusted_connection=yes;";
var migrationsAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;
services.AddIdentityServer()
.AddDeveloperSigningCredential()
.AddProfileService<IdentityServerProfileService>()
.AddResourceOwnerValidator<IdentityResourceOwnerPasswordValidator>()
// this adds the config data from DB (clients, resources)
.AddConfigurationStore(options =>
{
options.ConfigureDbContext = builder =>
{
builder.UseSqlServer(connectionString,
sql => sql.MigrationsAssembly(migrationsAssembly));
};
})
// this adds the operational data from DB (codes, tokens, consents)
.AddOperationalStore(options =>
{
options.ConfigureDbContext = builder =>
builder.UseSqlServer(connectionString,
sql => sql.MigrationsAssembly(migrationsAssembly));
// this enables automatic token cleanup. this is optional.
options.EnableTokenCleanup = true;
options.TokenCleanupInterval = 30;
});
// Add jwt validation.
services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddIdentityServerAuthentication(options =>
{
// base-address of your identityserver
options.Authority = "https://localhost:44386";
options.ClaimsIssuer = "https://localhost:44386";
// name of the API resource
options.ApiName = "api1";
options.ApiSecret = "secret";
options.RequireHttpsMetadata = false;
options.SupportedTokens = SupportedTokens.Reference;
});
//...
}

一切都很好，我可以从Google OAuth2返回索赔，使用Google电子邮件地址在数据库中查找用户，如果他们没有任何帐户，请注册。
我的问题是：如何使用我在HandleExternalLogin方法中收到的Google OAuth2声明来生成参考令牌，将其保存到PersistedGrants表并返回到客户端。
这意味着当用户访问https://localhost:44386/api/google/login后，在重定向到Google同意屏幕后，他们可以接收由access_token生成的refresh_token，IdentityServer4。
谢谢，
AccessTokenType.Reference适用于TokenTypes.AccessToken而不是TokenTypes.IdentityToken，就像你的片段一样。一般来说，遵循original quickstart更简单，然后根据您的需要扩展the generic code。我现在在上面的代码片段中看到的只是您的特定内容，而不是默认部分，负责创建IdSrv会话并重定向回客户端。
如果您仍想手动创建令牌：
ITokenService注入您的控制器。TokenTypes.AccessToken而不是
TokenTypes.IdentityTokenvar tokenHandle = await TokenService.CreateAccessTokenAsync(token);tokenHandle是PersistedGrantStore的关键
