No se puede obtener EnableOauth2Sso Working-BadCredentialsException: no se pudo obtener el token de acceso

Question

Intento que funcione una aplicación SSO de Spring OAuth2 simple y no he podido hacerlo. Aquí están los pasos y resultados de lo que sucedió:

1. Hit endpoint /user , que está protegido por OAuth2
2. Me reenvían a un simple servidor de autorizaciones de Spring OAuth2
3. Me autentico en el servidor de autorizaciones
4. Aprobé el acceso

5. Luego aparece una página de error de etiqueta blanca en la aplicación OAuth2 SSO con lo siguiente:

   Whitelabel Error Page
   
   This application has no explicit mapping for /error, so you are seeing this as a fallback.

   There was an unexpected error (type=Unauthorized, status=401).
   Authentication Failed: Could not obtain access token

El código de autorización está en la URL. Aquí está la URL de muestra a continuación:

http://localhost:8083/login?code=9s63rU&state=Fo9S2M

No veo una HTTP POST para el servidor de autorización /oauth/token punto final /oauth/token para adquirir un JWT. Validé esto a través del punto final /trace en el servidor de autorización.

La pila de excepciones es:

Si necesita el código para el servidor de autorización, hágamelo saber.

:: ACTUALIZACIÓN 1 ::

Empecé a depurar esto y descubrí que la excepción real lanzada es una InvalidRequestException con un mensaje de: Se Possible CSRF detected - state parameter was present but no state could be found : el Possible CSRF detected - state parameter was present but no state could be found en la line 244 de AuthorizationCodeAccessTokenProvider .

Traté de modificar mi Oauth2SsoConfigurerAdapter a esto, pero sigo recibiendo la misma excepción:

@Configuration
protected static class SecurityConfiguration extends OAuth2SsoConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.logout().and().antMatcher("/**").authorizeRequests()
                .antMatchers("/index.html", "/home.html", "/", "/login").permitAll()
                .anyRequest().authenticated().and().csrf()
                .csrfTokenRepository(csrfTokenRepository()).and()
                .addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);
    }

    private Filter csrfHeaderFilter() {
        return new OncePerRequestFilter() {
            @Override
            protected void doFilterInternal(HttpServletRequest request,
                                            HttpServletResponse response, FilterChain filterChain)
                    throws ServletException, IOException {
                CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class
                        .getName());
                if (csrf != null) {
                    Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");
                    String token = csrf.getToken();
                    if (cookie == null || token != null
                            && !token.equals(cookie.getValue())) {
                        cookie = new Cookie("XSRF-TOKEN", token);
                        cookie.setPath("/");
                        response.addCookie(cookie);
                    }
                }
                filterChain.doFilter(request, response);
            }
        };
    }

    private CsrfTokenRepository csrfTokenRepository() {
        HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
        repository.setHeaderName("X-XSRF-TOKEN");
        return repository;
    }
}

:: ACTUALIZACIÓN 2 ::

InvalidRequestException se lanza porque preservedState de DefaultAccessTokenRequest devuelve null (consulte la line 239 de AuthorizationCodeAccessTokenProvider ).

El estado preservedState se establece en DefaultAccessTokenRequest en Oauth2RestTemplate en la line 212 y determiné que el mapa DefaultOauth2ClientContext estaba vacío y devuelve null .

Intentaré validar la llamada a setPreserveState en DefaultOAuth2ClientContext continuación.

:: ACTUALIZACIÓN 3 ::

Actualicé la configuración de mi cliente para usar Github en lugar de mi propio servidor de autorizaciones Spring OAuth2 y funciona. Para mí eso indica que puede haber un problema con la configuración de mi servidor de autorización.

Intentaré depurar un poco en mi servidor OAuth para ver si puedo descubrir qué está pasando mal.

:: ACTUALIZACIÓN 4 ::

¡Éxito! Estaba ejecutando la autorización OAuth2 y los servidores cliente en el mismo host, pero diferentes puertos. Cuando establecí la ruta de contexto del cliente a algo que no sea la raíz, todo comenzó a funcionar.

Sospecho que esto tiene algo que ver con JSESSIONID y las cookies. ¿Alguien podría vincularme a la documentación para explicar cómo funciona esto para referencia futura?

¡Gracias!

Answer 1

Centinul, ya que ha descubierto que esto sucede debido a un conflicto de cookies, desafortunadamente las cookies no respetan los números de puerto. Y entonces ambas aplicaciones interfieren entre sí ya que ambas configuran JSESSIONID .

Hay dos soluciones fáciles:

1. use server.context-path para mover cada aplicación a diferentes rutas, tenga en cuenta que debe hacer esto para ambos
2. establezca server.session.cookie.name para una aplicación en algo diferente, por ejemplo, APPSESSIONID

Sugeriría poner esta solución en un perfil que active solo para localhost.

Answer 2

Creación de una aplicación de cliente: la ruta de contexto debe ser explícita si está ejecutando tanto el cliente como el servidor de autenticación en el host local; de lo contrario, las rutas de acceso de las cookies entrarán en conflicto y las dos aplicaciones no podrán ponerse de acuerdo sobre un identificador de sesión.
