Keycloak：无法在 Spring Boot 应用程序中加载 URL

Question

我目前正在尝试开发一个使用 keycloak 保护的 Spring Boot Rest Api。

当我尝试调用必须识别用户的 api 时出现错误。

错误信息如下：

2020-04-10 16:09:00.324  WARN 44525 --- [nio-8080-exec-7]

我不知道Failed to load URLs from 是什么意思。当我单击链接并显示配置文件时，我可以访问此端。

设置

钥匙斗篷：

Keycloak 服务器在网络中，所以没有 localhost。

我创建了一个领域（测试领域）
我创建了一个客户端（测试客户端）
我创建了一个用户（测试用户）
我在创建的客户端 (ADMIN) 中有一个角色
我已将角色 (ADMIN) 分配给用户 (test-user)

客户端的客户端协议为openid-connect，访问类型为confidental。

春季启动：

Spring Boot REST 应用程序正在 localhost:8080 上运行。

我在 keycloak 配置之后添加了 applications.properties。

keycloak.realm={{test-realm}}
keycloak.auth-server-url = https://{{keycloakserver}}.de/auth
keycloak.resource = {{test-client}}
keycloak.ssl-required=external
keycloak.bearer-only=true
keycloak.principal-attribute=preferred_username
keycloak.use-resource-role-mappings = true

为了确保测试用户只能访问一个 api 调用，我使用以下配置。

 @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);
        http.authorizeRequests()
                .antMatchers("/getTest")
                .hasRole("ADMIN")
                .anyRequest()
                .authenticated();
    }

测试

当我用 Postman 拨打 http://localhost:8080/getTest 时，我得到了正确的 401 Unauthorized。

然后我用Authorization 和登录的test-user 的访问令牌调用了相同的URL。

通过第二次调用，我收到了上面的错误消息。

有人知道吗？ 如果我错过了您需要知道的配置值，请询问。

感谢您的帮助。

        KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
        auth.authenticationProvider(keycloakAuthenticationProvider);
    }

    @Bean

TestController.java（这只是测试 getter）：

  @GetMapping("/getTest")
    public @ResponseBody ResponseEntity getTest() {

        return ResponseEntity.status(ResponseValues.ITEMDELETEFAILED.getResponseCode()).body(ResponseValues.ITEMDELETEFAILED.getResponseMessage());

    }

请求是通过邮递员提出的，代码如下：

curl --location --request GET 'http://localhost:8080/getTest' \
--header 'Authorization: Bearer eyJhbGciOiJSUzI1NiIsInR5cCIgOiAiSldUI...' \
--header 'Cookie: JSESSIONID=41E8E82178FA181817...'

Answer 1

就我而言：领域名称不正确。它区分大小写。当我将其更改为：

keycloak.realm = demo

我写过

keycloak.realm = Demo

Answer 2

我遇到了同样的问题，对我来说它也与有缺陷的配置值有关。

keycloak.auth-server-url = https://{{keycloakserver}}.de/auth

首先我忘记了/auth，然后我使用了http 而不是https。

Answer 3

尝试将hasRole更改为hasAuthority或在hasRole("ROLE_ADMIN")这样的角色前添加前缀ROLE_

Answer 4

我自己解决了这个问题。

我注意到我的 spring boot sdk 是一个 android sdk。我不知道这怎么会发生。 我将它更改为 java sdk，它就像一个魅力。

Answer 5

我遇到了类似的问题。就我而言，我没有意识到我的 application.properties 文件中的“keycloak.auth-server-url”末尾有一个空格。

这样，keycloak 适配器尝试访问无效的 URL。

也许这可以帮助遇到类似问题并找到此线程的人。

Answer 6

我为 keycloak.auth-server-url 输入了错误的值。
