간략한 소개

보안 소스 분석 시리즈는 OpenIdConnect가 발행 토큰 소위 원격 인증 수단은 다른 사이트에 의해 달성 원격 인증 프레임 워크에 속하는 OAuth2.0에 마이크로 소프트가 제공하는 다양한 인증 프레임 워크를 설명합니다.

IdentityServer4가 인증 기관 프레임 워크 OpenIdConnect 계약을 기반으로, 우리는 중앙 집중식 인증 서비스를 구축 할 수 있습니다.

OpenIdConnect 프로토콜 요구 사항 문서에 바로 이해할 수있다, 그것은 수요 이벤트에 API의 범위를 기반 idsv4.

idsv 또한 정보가 아래에 볼 수 있습니다 모르는 경우,이 시리즈는 주로 이해를 심화 할 수있는 계약과 함께, 애타게 idsv 소스에 배우고있다.

UserIdentityServer - 미들웨어 논리

  • 체크섬을 수행
  • BaseUrlMiddleware 미들웨어 : 설정 base을
  • CORS는 크로스 도메인을 구성 : CorsPolicyProvider 클라이언트 정보를 기반으로 동적 전략을 생성
  • 당신이 IdentityServer를 사용하는 경우 IdentityServerMiddlewareOptions 기본 통화 UseAuthentication, 그렇게하지 등록 인증 미들웨어를 반복
  • 사용 MutualTlsTokenEndpointMiddleware 미들웨어 : 클라이언트 요구 사항, 서버가 HTTPS를 사용은 기본이 열려 있지 않습니다
  • 사용 IdentityServerMiddleware 미들웨어 : IEndpointRouter이 EndPointHandler 과정 요청에 의해 발견하는 경우, 요청에 따라 IEndpointHandler 일치 찾을 수 있습니다.
public static IApplicationBuilder UseIdentityServer(this IApplicationBuilder app, IdentityServerMiddlewareOptions options = null)
{
    app.Validate();

    app.UseMiddleware<BaseUrlMiddleware>();

    app.ConfigureCors();

    // it seems ok if we have UseAuthentication more than once in the pipeline --
    // this will just re-run the various callback handlers and the default authN 
    // handler, which just re-assigns the user on the context. claims transformation
    // will run twice, since that's not cached (whereas the authN handler result is)
    // related: https://github.com/aspnet/Security/issues/1399
    if (options == null) options = new IdentityServerMiddlewareOptions();
    options.AuthenticationMiddleware(app);

    app.UseMiddleware<MutualTlsTokenEndpointMiddleware>();
    app.UseMiddleware<IdentityServerMiddleware>();

    return app;
}

발문

idsv 코드의 양이 클래스의 번호로, 매우 큽니다. 그러나 매우 표준 코딩 스타일, 상황은 매우 분명하다.
