序

前面的一篇文章讲了spring security oauth2的client credentials授权模式，一般用于跟用户无关的，开放平台api认证相关的授权场景。本文主要讲一下跟用户相关的授权模式之一password模式。

回顾四种模式

OAuth 2.0定义了四种授权方式。

• 授权码模式（authorization code）
• 简化模式（implicit）
• 密码模式（resource owner password credentials）
• 客户端模式（client credentials）(主要用于api认证，跟用户无关)

maven

        <dependency>
            <groupId>org.springframework.security.oauth</groupId>
            <artifactId>spring-security-oauth2</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

配置

security config

支持password模式要配置AuthenticationManager

@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

//需要正常运行的话，需要取消这段注释，原因见下面小节
//    @Override
//    public void configure(HttpSecurity http) throws Exception {
//        http.csrf().disable();
//        http.requestMatchers().antMatchers("/oauth/**")
//                .and()
//                .authorizeRequests()
//                .antMatchers("/oauth/**").authenticated();
//    }

    //配置内存模式的用户
    @Bean
    @Override
    protected UserDetailsService userDetailsService(){
        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
        manager.createUser(User.withUsername("demoUser1").password("123456").authorities("USER").build());
        manager.createUser(User.withUsername("demoUser2").password("123456").authorities("USER").build());
        return manager;
    }

    /**
     * 需要配置这个支持password模式
     * support password grant type
     * @return
     * @throws Exception
     */
    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}

这个是比client credentials模式新增的配置，主要配置用户以及authenticationManager

auth server配置

@Configuration
@EnableAuthorizationServer //提供/oauth/authorize,/oauth/token,/oauth/check_token,/oauth/confirm_access,/oauth/error
public class OAuth2ServerConfig extends AuthorizationServerConfigurerAdapter {

    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer
                .tokenKeyAccess("permitAll()") //url:/oauth/token_key,exposes public key for token verification if using JWT tokens
                .checkTokenAccess("isAuthenticated()") //url:/oauth/check_token allow check token
                .allowFormAuthenticationForClients();
    }
    
    /**
     * 注入authenticationManager
     * 来支持 password grant type
     */
    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("demoApp")
                .secret("demoAppSecret")
                .authorizedGrantTypes("client_credentials", "password", "refresh_token")
                .scopes("all")
                .resourceIds("oauth2-resource")
                .accessTokenValiditySeconds(1200)
                .refreshTokenValiditySeconds(50000);
}

这里记得注入authenticationManager来支持password模式

否则报错如下

resource server 配置

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

//    /**
//      * 要正常运行，需要反注释掉这段，具体原因见下面分析
//     * 这里设置需要token验证的url
//     * 这些需要在WebSecurityConfigurerAdapter中排查掉
//     * 否则优先进入WebSecurityConfigurerAdapter,进行的是basic auth或表单认证,而不是token认证
//     * @param http
//     * @throws Exception
//     */
//    @Override
//    public void configure(HttpSecurity http) throws Exception {
//        http.requestMatchers().antMatchers("/api/**")
//                .and()
//                .authorizeRequests()
//                .antMatchers("/api/**").authenticated();
//    }


}

验证

请求token

curl -i -X POST -d "username=demoUser1&password=123456&grant_type=password&client_id=demoApp&client_secret=demoAppSecret" http://localhost:8080/oauth/token

curl -i http://localhost:8080/api/blog/1\?access_token\=4cfb16f9-116c-43cf-a8d4-270e824ce5d7

或者

curl -i -H "Accept: application/json" -H "Authorization: Bearer 4cfb16f9-116c-43cf-a8d4-270e824ce5d7" -X GET http://localhost:8080/api/blog/1

WebSecurityConfigurerAdapter与ResourceServerConfigurerAdapter

二者都有针对http security的配置，他们的默认配置如下

WebSecurityConfigurerAdapter

spring-security-config-4.2.3.RELEASE-sources.jar!/org/springframework/security/config/annotation/web/configuration/WebSecurityConfigurerAdapter.java

@Order(100)
public abstract class WebSecurityConfigurerAdapter implements
        WebSecurityConfigurer<WebSecurity> {
        //......
protected void configure(HttpSecurity http) throws Exception {
        logger.debug("Using default configure(HttpSecurity). If subclassed this will potentially override subclass configure(HttpSecurity).");

        http
            .authorizeRequests()
                .anyRequest().authenticated()
                .and()
            .formLogin().and()
            .httpBasic();
    }

    //......
}   

可以看到WebSecurityConfigurerAdapter的order是100

ResourceServerConfigurerAdapter

spring-security-oauth2-2.0.14.RELEASE-sources.jar!/org/springframework/security/oauth2/config/annotation/web/configuration/ResourceServerConfigurerAdapter.java

public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().anyRequest().authenticated();
    }

它的order是SecurityProperties.ACCESS_OVERRIDE_ORDER - 1
spring-boot-autoconfigure-1.5.5.RELEASE-sources.jar!/org/springframework/boot/autoconfigure/security/oauth2/resource/ResourceServerProperties.java

/**
     * The order of the filter chain used to authenticate tokens. Default puts it after
     * the actuator endpoints and before the default HTTP basic filter chain (catchall).
     */
    private int filterOrder = SecurityProperties.ACCESS_OVERRIDE_ORDER - 1;

由此可见WebSecurityConfigurerAdapter的拦截要优先于ResourceServerConfigurerAdapter

二者关系

• WebSecurityConfigurerAdapter用于保护oauth相关的endpoints，同时主要作用于用户的登录(form login,Basic auth)
• ResourceServerConfigurerAdapter用于保护oauth要开放的资源，同时主要作用于client端以及token的认证(Bearer auth)

因此二者是分工协作的

• 在WebSecurityConfigurerAdapter不拦截oauth要开放的资源

@Override
    public void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        http.requestMatchers().antMatchers("/oauth/**")
                .and()
                .authorizeRequests()
                .antMatchers("/oauth/**").authenticated();
    }

• 在ResourceServerConfigurerAdapter配置需要token验证的资源

@Override
    public void configure(HttpSecurity http) throws Exception {
        http.requestMatchers().antMatchers("/api/**")
                .and()
                .authorizeRequests()
                .antMatchers("/api/**").authenticated();
    }

这样就大功告成
