OAuth2NetCore

OAuth 2.0 / OpenID Connect 协议核心库，提供授权码（含 PKCE）、客户端凭证、资源所有者密码、隐式与刷新令牌等标准 grant type 的服务端实现。netstandard2.0 目标。

主要类型

  • IAuthServer / DefaultAuthServer — Token / Authorize / EndSession / ClearToken 请求处理器。
  • AuthServerOptions — 服务端配置（PKCE 必需、签名算法、各 store/factory 注册）。
  • ClientOptions — 客户端配置（OAuth client 接入参数）。
  • IClientValidator / DefaultClientValidator — Basic Auth 提取与客户端凭证、redirect URI、grant、scope、response type 校验。
  • IPkceValidator / DefaultPkceValidator — PKCE S256 / plain 校验。
  • ITokenGenerator / DefaultTokenGenerator — 基于 Microsoft.IdentityModel.JsonWebTokens 的 JWT 签发，默认算法 PS256。
  • ISecretEncryptor / X509SecretEncryptor — RSA OAEP-SHA256 加密器（v2.0+）。
  • IClientStore / IAuthCodeStore / IRefreshTokenInfoStore / IStateStore — 各存储接口。内存版默认实现包含在主库中；Redis 实现在 OAuth2NetCore.Redis 包。

快速接入

services.AddOAuth2AuthServer(options => {
    options.SecurityKeyProviderFactory = _ => new X509SecurityKeyProvider(cert);
    options.ClientStoreFactory          = _ => myClientStore;
    options.RefreshTokenInfoStore       = _ => myRefreshTokenStore;
    options.StateStoreFactory           = _ => myStateStore;
    options.TokenClaimBuilderFactory    = _ => new MyTokenClaimBuilder();
    options.ResourceOwnerValidatorFactory = sp => new MyResourceOwnerValidator(...);
    // options.SigningAlgorithm   = SecurityAlgorithms.RsaSsaPssSha256;  // 默认 PS256
    // options.PKCERequired       = true;   // 默认开
    // options.AllowPlainPkce     = false;  // 默认拒绝 plain，仅过渡期可放行
});

// ...

app.UseEndpoints(endpoints => {
    endpoints.MapPost("/connect/token",        authServer.TokenRequestHandler);
    endpoints.MapGet ("/connect/authorize",    authServer.AuthorizeRequestHandler);
    endpoints.MapGet ("/connect/endsession",   authServer.EndSessionRequestHandler);
    endpoints.MapPost("/connect/endsession",   authServer.ClearTokenRequestHandler);
});

v2.0 安全加固要点

v2.0 是 major security release。完整漏洞清单与下游升级指南见仓库内：

从 v1.x 升级前必读——RSA padding、PKCE 默认值、Cookie 名等均为 breaking change。
