如何在Spring Boot应用程序中使用Keycloak策略执行器

Question

Keycloak策略执行器不使用示例Sprint引导应用程序。

我正在使用Keycloak Version6.0.1，并试图集成一个示例Sprint boot应用程序（Sprint boot Version2.1.3)。我的目标是在Keycloak中设置策略和权限，并在我的示例Spring Boot应用程序中使用Keycloak策略强制器，以便使用在Keycloak中定义的适当权限自动执行所有授权决策，并且在示例应用程序中不需要任何代码。

public class JPAUserResource {

    @Autowired
    private UserRepository userRepo;

    @GetMapping(path = "/jpausers")
    public List<JPAUser> retrieveAllUsers() {
        return userRepo.findAll();
    }
}

我的application.properties文件包含以下内容：

server.port=38080
spring.jpa.show-sql=true
spring.h2.console.enabled=true
logging.level.org.springframework.security=DEBUG
logging.level.org.keycloak.adapters.authorization=DEBUG
#Keycloak Configuration
keycloak.auth-server-url=http://192.168.154.190:18180/auth

keycloak.resource=login-app

keycloak.credentials.secret=195925d6-b258-407d-a65d-f1fd12d7a876

keycloak.policy-enforcer-config.paths[0].path=/jpausers
keycloak.policy-enforcer-config.paths[0].methods[0].method=GET

我的Keycloak授权设置如下：

{
  "allowRemoteResourceManagement": true,
  "policyEnforcementMode": "ENFORCING",
  "resources": [
    {
      "name": "Default Resource",
      "type": "urn:login-app:resources:default",

      "attributes": {},
      "_id": "501febc8-f3e1-411f-aecf-376b4786c24e",
      "uris": [
        "/*"
      ]
    },
    {
      "name": "jpausers",
      "ownerManagedAccess": false,
      "displayName": "jpausers",
      "attributes": {},
      "_id": "a8f691db-39ef-4b2c-80fb-37224e270f1e",
      "uris": [
        "/jpausers"
      ],
      "scopes": [
        {
          "name": "GET"
        },
        {
          "name": "POST"
        }
      ]
    }
  ],
  "policies": [
    {
      "id": "94518189-3794-451c-9996-eec22543d802",
      "name": "Default Policy",
      "description": "A policy that grants access only for users within this realm",
      "type": "js",
      "logic": "POSITIVE",
      "decisionStrategy": "AFFIRMATIVE",
      "config": {
        "code": "// by default, grants any permission associated with this policy\n$evaluation.grant();\n"
      }
    },
    {
      "id": "0242cf72-365d-49ae-8d5b-4ced24736f24",
      "name": "test_jpa",
      "type": "role",
      "logic": "POSITIVE",
      "decisionStrategy": "UNANIMOUS",
      "config": {
        "roles": "[{\"id\":\"jpa\",\"required\":false}]"
      }
    },
    {
      "id": "5c34e2b4-a56a-45f9-a1cc-94788bcb41b0",
      "name": "test_perm1",
      "type": "resource",
      "logic": "POSITIVE",
      "decisionStrategy": "UNANIMOUS",
      "config": {
        "resources": "[\"jpausers\"]",
        "applyPolicies": "[\"test_jpa\"]"
      }
    }
  ],
  "scopes": [
    {
      "id": "4ee351e6-7095-453a-a4f4-badbc9ec1ba0",
      "name": "GET",
      "displayName": "GET"
    },
    {
      "id": "9119aab2-75a0-49d1-a076-8d9210c3e457",
      "name": "POST",
      "displayName": "POST"
    }
  ]
}

当我向我的Rest API'/jpausers'发送请求时，它会失败，控制台上会出现以下消息：

*19:17:52.044 [http-nio-38080-exec-1] INFO  o.k.a.authorization.PolicyEnforcer - Paths provided in configuration.

有人能帮忙解决这个问题吗？我怎么解决这个？我必须让UMA让政策执行者工作吗？

通过快速查看，我可以看到您在application.properties中的映射还没有完成，您还没有将HTTP方法映射到您在KeyCloak中配置的范围。像这样的东西

keycloak.policy-enforcer-config.paths[0].path=/jpausers
keycloak.policy-enforcer-config.paths[0].methods[0].method=GET 
keycloak.policy-enforcer-config.paths[0].methods[0].scopes[0]=GET
