Spring Security + Keycloak：接受承载令牌答案

【问题标题】：Spring Security + Keycloak: Accept Bearer TokenSpring Security + Keycloak：接受承载令牌
【发布时间】：2018-07-22 23:44:05
【问题描述】：

不知何故，我迷失了 Spring Security 和 Keycloak。

在一个应用程序中，我成功从我的 Keycloak 实例接收到一个访问令牌。然后我使用这个令牌对我的 Spring Security 服务器（它使用相同的 Keycloak 实例）发出请求。

但我得到的只是 403 错误。

以下是代码摘录（用 kotlin 编写）：

安全配置：

@KeycloakConfiguration
abstract class MyConfig : KeycloakWebSecurityConfigurerAdapter() {

   @Autowired
   lateinit var keycloakClientRequestFactory: KeycloakClientRequestFactory

   @Bean
   @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
   fun keycloakRestTemplate(): KeycloakRestTemplate {
      return KeycloakRestTemplate(keycloakClientRequestFactory)
   }

   @Autowired
   @Throws(Exception::class)
   fun configureGlobal(auth: AuthenticationManagerBuilder) {
      val keycloakAuthenticationProvider = keycloakAuthenticationProvider()
      keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(SimpleAuthorityMapper())
      auth.authenticationProvider(keycloakAuthenticationProvider)
   }

   @Bean
   fun KeycloakConfigResolver(): KeycloakConfigResolver {
      return KeycloakSpringBootConfigResolver()
   }

   @Throws(Exception::class)
   override fun configure(http: HttpSecurity) {
      http.csrf().disable()
        .cors().and()
        .authorizeRequests()
        .anyRequest().authenticated()
      http.requiresChannel().anyRequest().requiresSecure()
   }

   @Bean
   override fun sessionAuthenticationStrategy(): SessionAuthenticationStrategy =
      RegisterSessionAuthenticationStrategy(SessionRegistryImpl())

   @Bean
   fun keycloakAuthenticationProcessingFilterRegistrationBean(
      filter: KeycloakAuthenticationProcessingFilter): FilterRegistrationBean {
      val registrationBean = FilterRegistrationBean(filter)
      registrationBean.isEnabled = false
      return registrationBean
   }

   @Bean
   fun keycloakPreAuthActionsFilterRegistrationBean(
      filter: KeycloakPreAuthActionsFilter): FilterRegistrationBean {
      val registrationBean = FilterRegistrationBean(filter)
      registrationBean.isEnabled = false
      return registrationBean
   }

   @Bean
   fun corsConfigurationSource(): CorsConfigurationSource {
      val configuration = CorsConfiguration()
      configuration.allowedOrigins = arrayListOf("*").toMutableList()
      configuration.allowedMethods = arrayListOf("HEAD", "GET", "POST", "PUT", "DELETE", "PATCH","OPTIONS")
      configuration.allowCredentials = true
      configuration.allowedHeaders = arrayListOf("Authorization", "Cache-Control", "Content-Type")
      val source = UrlBasedCorsConfigurationSource()
      source.registerCorsConfiguration("/**", configuration)
      return source
   }
}

在我的控制器中：

   @RequestMapping("/test")
   @ResponseBody
   fun test(): String {
      return "success"
   }

在我对服务器的调用中，我可以验证授权标头设置如下：Authorization: Bearer [Token]

我错过了什么？我很高兴有任何帮助！

【问题讨论】：

KC 服务器上的适配器是否有任何错误？
感谢您的回复。 keycloak 服务器不会抛出任何异常。您是说 Spring Security 服务器吗？我添加了 Spring Security 的调试日志，并将考虑为 KC 服务器启用调试模式。
好吧，更奇怪的是：Spring 服务器上的 keycloak 调试消息表明用户已成功获得令牌授权。但他似乎没有任何角色或权力分配给他。
我发现了错误。我在 SecurityConfig 的配置方法中错过了对超类的调用（即 super.configure(http)）。

标签： spring-security keycloak

【解决方案1】：

为了完整起见，我回答这个问题：

就像在对该问题的评论中所述，问题出在KeycloakWebSecurityConfigurerAdapter 中对super.configure(http) 的调用。

因此，如果您遇到类似的错误，请检查您是否进行了此调用。配置应如下所示：

@KeycloakConfiguration
class MyConfig : KeycloakWebSecurityConfigurerAdapter() {
   // [...]
   @Throws(Exception::class)
   override fun configure(http: HttpSecurity) {
      super.configure(http) // this call was missing
      // [...]
   }
}

【讨论】：

您对如何验证令牌有任何想法吗？我也试图在没有任何角色检查的情况下验证令牌。
对不起，我不能帮你。我不再参与这个项目。好看！
我能够通过遵循 Spring Security Documentation 使其工作。如果有人需要我的 github repo 代码，请告诉我。
