Spring应用程序keycloack上的基本auth

Question

我发现的大多数示例都使用org.keycloak:keycloak-spring-boot-starter的重定向特性。虽然我在这里找到了enable-basic-auth，但它对我不起作用。我知道必须使用keycloak.bearer-only=true来关闭重定向，但它的工作原理是这样的，而不是重定向，它为未经授权的用户返回401。

我的安全配置：

@Configuration
@EnableWebSecurity
@ComponentScan(basePackageClasses = KeycloakSecurityComponents.class)
public class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {

    @Bean
    public KeycloakSpringBootConfigResolver KeycloakConfigResolver() {
        return new KeycloakSpringBootConfigResolver();
    }

    @Override
    protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
        return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
    }

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

我的keycloak属性（我不使用占位符，这只是出于安全考虑）：

keycloak.auth-server-url=https://${keycloak.host}/auth/
keycloak.realm=master
keycloak.resource=${client.name}
keycloak.enable-basic-auth=true
keycloak.credentials.secret=${client.secret}

下面是一种通过keycloak openid和资源所有者密码凭据流向应用程序添加基本auth的方法。

首先，您需要将其添加到pom.xml中：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.keycloak.bom</groupId>
            <artifactId>keycloak-adapter-bom</artifactId>
            <version>4.2.0.Final</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

...

<dependencies>
...
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
        <dependency>
            <groupId>org.keycloak</groupId>
            <artifactId>keycloak-spring-boot-starter</artifactId>
        </dependency>
...
</dependencies>

添加keycloak服务器属性：

keycloak.auth-server-url=https://${keycloak.host}/auth/
keycloak.realm=master
keycloak.resource=${client.name}
keycloak.credentials.secret=${client.secret}
keycloak.enable-basic-auth=true
keycloak.bearer-only=true

@Configuration
@ComponentScan(basePackageClasses = KeycloakSecurityComponents.class)
@EnableWebSecurity
public class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {

    @Bean
    public KeycloakAuthenticationProvider authenticationProvider() {
        KeycloakAuthenticationProvider provider = new KeycloakAuthenticationProvider();
        provider.setGrantedAuthoritiesMapper(new SimpleAuthorityMapper());
        return provider;
    }

    @Bean
    public KeycloakSpringBootConfigResolver KeycloakConfigResolver() {
        return new KeycloakSpringBootConfigResolver();
    }

    @Override
    protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
        return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);
        http
                .csrf().disable()
                .exceptionHandling().authenticationEntryPoint((request, response, authException) -> {
                    response.addHeader(HttpHeaders.WWW_AUTHENTICATE, "Basic realm=\"Restricted Content\"");
                    response.sendError(HttpStatus.UNAUTHORIZED.value(), HttpStatus.UNAUTHORIZED.getReasonPhrase());
                })
                .and()
                .authorizeRequests()
                .antMatchers("/admin/**").hasRole("admin")
                .anyRequest().permitAll();
    }
}

        .exceptionHandling().authenticationEntryPoint((request, response, authException) -> {
            response.addHeader(HttpHeaders.WWW_AUTHENTICATE, "Basic realm=\"Restricted Content\"");
            response.sendError(HttpStatus.UNAUTHORIZED.value(), HttpStatus.UNAUTHORIZED.getReasonPhrase());
        })
