基于角色的身份验证不适用于 Keycloak 和 Java Spring

问题描述 投票:0回答:1

我一直在遵循本教程:https://www.baeldung.com/spring-boot-keycloak使用Keycloak设置我的Spring应用程序。身份验证工作正常,但是当我想添加基于角色的身份验证时,例如

.requestMatchers(new AntPathRequestMatcher("/api/v1/user/**")).hasRole("user")

我总是收到以下错误

Bearer error="insufficient_scope", error_description="The request requires higher privileges than provided by the access token.", error_uri="https://tools.ietf.org/html/rfc6750#section-3.1"

我已经使用

检查了权威机构
SecurityContextHolder.getContext().getAuthentication().getAuthorities();

并且它只有带有

SCOPE_
前缀的。 我还检查了令牌,它正确返回了这个

 "realm_access": {
    "roles": [
      "offline_access",
      "uma_authorization",
      "default-master-realm",
      "user"
    ]
  },

除了其他领域。

这是我的

KeycloakConfig
课程:

                    mappedAuthorities.addAll(generateAuthoritiesFromClaim(roles));
                }
            } else {
                var oauth2UserAuthority = (OAuth2UserAuthority) authority;
                Map<String, Object> userAttributes = oauth2UserAuthority.getAttributes();

                if (userAttributes.containsKey(REALM_ACCESS_CLAIM)) {
                    Map<String, Object> realmAccess = (Map<String, Object>) userAttributes.get(
                            REALM_ACCESS_CLAIM);
                    Collection<String> roles = (Collection<String>) realmAccess.get(ROLES_CLAIM);
                    mappedAuthorities.addAll(generateAuthoritiesFromClaim(roles));
                }
            }
            return mappedAuthorities;
        };
    }

    Collection<GrantedAuthority> generateAuthoritiesFromClaim(Collection<String> roles) {
        return roles.stream().map(role -> new SimpleGrantedAuthority("ROLE_" + role)).collect(
                Collectors.toList());
    }
}

看起来GrantedAuthoritesMapper没有被调用,你知道为什么吗? 这是我在

pom.xml
中添加的内容:

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-oauth2-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-oauth2-resource-server</artifactId>
        </dependency>

这是我在 application.properties 中添加的内容:

spring.security.oauth2.client.registration.keycloak.client-id=${KEYCLOAK_CLIENT_ID:test-backend}
spring.security.oauth2.client.registration.keycloak.authorization-grant-type=${KEYCLOAK_AUTHORIZATION_GRANT_TYPE:password}
spring.security.oauth2.client.registration.keycloak.scope=${KEYCLOAK_SCOPE:openid}
spring.security.oauth2.client.provider.keycloak.issuer-uri=${KEYCLOAK_ISSUER_URI:http://localhost:8080/realms/master}
spring.security.oauth2.client.provider.keycloak.user-name-attribute=${KEYCLOAK_USER_NAME_ATTRIBUTE:username}
spring.security.oauth2.resourceserver.jwt.issuer-uri=${KEYCLOAK_RESOURCE_SERVER_JWT_ISSUER_URI:http://localhost:8080/realms/master}

我使用

http://localhost:8080/realms/master/protocol/openid-connect/token
获取令牌 然后我使用获得的令牌将请求发送到我的应用程序,但我总是收到上述错误。有谁知道我该如何解决这个问题?

java spring oauth-2.0 keycloak

hasRole('user')
需要
ROLE_user
权限

将 Keycloak 角色映射到 Spring Security 权限时,用户

hasAuthority('user')
或添加
ROLE_
前缀。

请勿在同一个安全过滤器链中使用
oauth2ResourceServer
oauth2Login

Spring Boot 提供不同的启动器是有原因的。我知道 Baeldung 教程就是这样制作的(以及许多其他作者的教程,他们在不了解自己在做什么的情况下互相复制),但这完全是无稽之谈:

  • oauth2ResourceServer
    正在配置一个 OAuth2 资源服务器,其中:
  • oauth2Login
    正在使用授权代码配置 OAuth2 客户端,其中:

这些要求差异太大,无法放在同一个

Security(Web)FilterChain
bean 中。

使用授权代码流进行用户“登录”的客户端也可以是资源服务器,但对于不同的消费者(可能还有不同的端点):

  • 像浏览器一样的用户代理,用于使用会话保护的端点
  • 程序化客户端,例如对使用承载令牌保护的端点进行集群健康检查

PS

您可能应该阅读我的教程简介以获得更多 OAuth2 背景知识。

我在同一个存储库中托管的附加启动器可以帮助您仅使用属性为Keycloak配置Spring应用程序(这些Spring应用程序主要是带有

oauth2Login
的OAuth2客户端或OAuth2资源服务器)
