Question

我正在尝试使用像keycloak这样的开源用户管理服务。构建一个angularJs应用程序，它将发送HTTP请求到由keycloak保护的REST端点。我在后端使用弹簧靴。我能够调用端点并获得不可能的结果，因为它应该阻止来自未授权源的请求。

这是我遵循的两个链接

keycloak with angular and spring boot

2。Github link to keycloak example

控制器，由用户将调用的REST端点组成。

@RequestMapping(value = "/api/getSample")
public test welcome() {
    return new test("sample");
}

@RequestMapping(value = "/check/test")
public test welcome2() {
    return new test("test");
}

使用CORS的Spring启动应用程序

@SpringBootApplication
public class Application 
{
    public static void main( String[] args )
    {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public FilterRegistrationBean corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("*");
        config.addAllowedHeader("*");
        config.addAllowedMethod("*");
        source.registerCorsConfiguration("/api/*", config);

        FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
        bean.setOrder(0);
        return bean;
    }
}

server.port = 8090

keycloak.realm = demo
keycloak.auth-server-url = http://localhost:8080/auth
keycloak.ssl-required = external
keycloak.resource = tutorial-backend
keycloak.bearer-only = true
keycloak.credentials.secret = 111-1111-111-111
keycloak.use-resource-role-mappings = true
keycloak.cors= true

keycloak.securityConstraints[0].securityCollections[0].name = spring secured api
keycloak.securityConstraints[0].securityCollections[0].authRoles[0] = user
keycloak.securityConstraints[0].securityCollections[0].patterns[0] = /api

keycloak.securityConstraints[0].securityCollections[1].name = insecure stuff
keycloak.securityConstraints[0].securityCollections[1].authRoles[0] = user
keycloak.securityConstraints[0].securityCollections[1].patterns[0] = /check

有两个测试用例

无需登录即可进行REST调用。在这种情况下，我可以返回结果。不应该是这种情况，我得到了阻止（得到401错误）。
登录时进行REST调用。我可以调用api / getSample，这是正确的行为。但是，当我致电检查/测试时，我得到XMLHttpRequest cannot load http://localhost:8090/check/test. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9000' is therefore not allowed access. The response had HTTP status code 403.

Answer 1

<强> 1）

我不知道您的测试究竟是什么样子，但也许系统认为您仍然登录？您可以尝试删除Cookie，以确保没有保存访问令牌。

另一个选项可能是Spring Boot无法识别Keycloak Adapter，因此无法保护访问。您主要通过添加keycloak-spring-boot-adapter和keycloak-tomcat8-adapter依赖项（more details here）来配置适配器。

2）

看起来CORS配置不正确。您可以考虑配置（more details here）的此实现：

@Bean
FilterRegistrationBean corsFilter(
        @Value("${tagit.origin:http://localhost:9000}") String origin) {
    return new FilterRegistrationBean(new Filter() {
        public void doFilter(ServletRequest req, ServletResponse res,
                             FilterChain chain) throws IOException, ServletException {
            HttpServletRequest request = (HttpServletRequest) req;
            HttpServletResponse response = (HttpServletResponse) res;
            String method = request.getMethod();
            // this origin value could just as easily have come from a database
            response.setHeader("Access-Control-Allow-Origin", origin);
            response.setHeader("Access-Control-Allow-Methods",
                    "POST,GET,PUT,DELETE");
            response.setHeader("Access-Control-Max-Age", Long.toString(60 * 60));
            response.setHeader("Access-Control-Allow-Credentials", "true");
            response.setHeader(
                    "Access-Control-Allow-Headers",
                    "Origin,Accept,X-Requested-With,Content-Type,Access-Control-Request-Method,Access-Control-Request-Headers,Authorization");
            if ("OPTIONS".equals(method)) {
                response.setStatus(HttpStatus.OK.value());
            }
            else {
                chain.doFilter(req, res);
            }
        }

        public void init(FilterConfig filterConfig) {
        }

        public void destroy() {
        }
    });
}

Answer 2

您还没有在pom.xml中添加Spring Boot Keycloak Adapter依赖项。

对于2.您还没有为/ check配置CORS（仅适用于/ api）

 <dependency>
      <groupId>org.keycloak</groupId>
      <artifactId>keycloak-spring-boot-adapter</artifactId>
      <version>${keycloak.version}</version>
  </dependency>

keycloak（spring boot）不验证REST端点
