我学习了一周的IdentityServer4
并成功实现了使用 ResourceOwnedPassword
流程的简单身份验证流程。
现在,我正在按照 这篇教程 实现使用 IdentityServer4 进行 Google 身份验证。
这是我的操作步骤:
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;
});
//...
}

一切进展顺利,我可以从Google OAuth2获取认证信息,使用Google电子邮件地址在数据库中查找用户,如果他们没有任何账户,那么就为他们注册。
我的问题是:我如何在HandleExternalLogin
方法中使用Google OAuth2的认证信息来生成参考令牌,将其保存到PersistedGrants表中并返回给客户端。
这意味着当用户访问https://localhost:44386/api/google/login
时,在被重定向到Google同意屏幕后,他们可以接收由IdentityServer4
生成的access_token
和refresh_token
。
谢谢。
in-memory
用户存储。由于缺乏详细的指南,反复阅读代码并找到自定义它的方法非常令人沮丧。现在,我只想知道是否可以手动生成reference token
并保存到persistedgrantstore
中。 - RedplaneAccessTokenType.Reference
,就可以了,不需要进一步编码。 - d_fin-memory
用户存储:您可以自由切换为基于 Identity 或自己的 DI 存储,而无需超出或重写总体逻辑。 - d_fCreateAccessTokenAsync(token);
,其行为取决于token.Type
和token.AccessTokenType
。如果它们是OidcConstants.TokenTypes.AccessToken
和AccessTokenType.Reference
,则会存储该令牌。 - d_f
