本文就来讲一下spring security oauth2的几个endpoint的认证

endpoint

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

@Configuration
@Import(TokenKeyEndpointRegistrar.class)
public class AuthorizationServerEndpointsConfiguration {

    private AuthorizationServerEndpointsConfigurer endpoints = new AuthorizationServerEndpointsConfigurer();

    @Autowired
    private ClientDetailsService clientDetailsService;

    @Autowired
    private List<AuthorizationServerConfigurer> configurers = Collections.emptyList();

    @PostConstruct
    public void init() {
        for (AuthorizationServerConfigurer configurer : configurers) {
            try {
                configurer.configure(endpoints);
            } catch (Exception e) {
                throw new IllegalStateException("Cannot configure enpdoints", e);
            }
        }
        endpoints.setClientDetailsService(clientDetailsService);
    }

    @Bean
    public AuthorizationEndpoint authorizationEndpoint() throws Exception {
        AuthorizationEndpoint authorizationEndpoint = new AuthorizationEndpoint();
        FrameworkEndpointHandlerMapping mapping = getEndpointsConfigurer().getFrameworkEndpointHandlerMapping();
        authorizationEndpoint.setUserApprovalPage(extractPath(mapping, "/oauth/confirm_access"));
        authorizationEndpoint.setProviderExceptionHandler(exceptionTranslator());
        authorizationEndpoint.setErrorPage(extractPath(mapping, "/oauth/error"));
        authorizationEndpoint.setTokenGranter(tokenGranter());
        authorizationEndpoint.setClientDetailsService(clientDetailsService);
        authorizationEndpoint.setAuthorizationCodeServices(authorizationCodeServices());
        authorizationEndpoint.setOAuth2RequestFactory(oauth2RequestFactory());
        authorizationEndpoint.setOAuth2RequestValidator(oauth2RequestValidator());
        authorizationEndpoint.setUserApprovalHandler(userApprovalHandler());
        return authorizationEndpoint;
    }

    @Bean
    public TokenEndpoint tokenEndpoint() throws Exception {
        TokenEndpoint tokenEndpoint = new TokenEndpoint();
        tokenEndpoint.setClientDetailsService(clientDetailsService);
        tokenEndpoint.setProviderExceptionHandler(exceptionTranslator());
        tokenEndpoint.setTokenGranter(tokenGranter());
        tokenEndpoint.setOAuth2RequestFactory(oauth2RequestFactory());
        tokenEndpoint.setOAuth2RequestValidator(oauth2RequestValidator());
        tokenEndpoint.setAllowedRequestMethods(allowedTokenEndpointRequestMethods());
        return tokenEndpoint;
    }

    @Bean
    public CheckTokenEndpoint checkTokenEndpoint() {
        CheckTokenEndpoint endpoint = new CheckTokenEndpoint(getEndpointsConfigurer().getResourceServerTokenServices());
        endpoint.setAccessTokenConverter(getEndpointsConfigurer().getAccessTokenConverter());
        endpoint.setExceptionTranslator(exceptionTranslator());
        return endpoint;
    }

    @Bean
    public WhitelabelApprovalEndpoint whitelabelApprovalEndpoint() {
        return new WhitelabelApprovalEndpoint();
    }

    @Bean
    public WhitelabelErrorEndpoint whitelabelErrorEndpoint() {
        return new WhitelabelErrorEndpoint();
    }

    //......
}

这里显示配置了如下几个

/oauth/authorize
/oauth/token
/oauth/check_token
/oauth/confirm_access
/oauth/error

endpoint的认证

/oauth/authorize

这个需要保护用户账号密码认证保护，否则会报

curl -i http://localhost:8080/oauth/authorize\?response_type\=code\&client_id\=demoApp\&redirect_uri\=http://localhost:8081/callback
HTTP/1.1 500
X-Application-Context: application
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Date: Sun, 10 Dec 2017 07:12:50 GMT
Connection: close

{"timestamp":1512889970484,"status":500,"error":"Internal Server Error","exception":"org.springframework.security.authentication.InsufficientAuthenticationException","message":"User must be authenticated with Spring Security before authorization can be completed.","path":"/oauth/authorize"}

/oauth/token

这个如果配置支持allowFormAuthenticationForClients的，且url中有client_id和client_secret的会走ClientCredentialsTokenEndpointFilter来保护
如果没有支持allowFormAuthenticationForClients或者有支持但是url中没有client_id和client_secret的，走basic认证保护

/oauth/check_token

这个走basic认证保护

/oauth/confirm_access

这个需要认证保护，否则报500

curl -i http://localhost:8080/oauth/confirm_access

HTTP/1.1 500
X-Application-Context: application
Cache-Control: no-store
Content-Type: application/json;charset=UTF-8
Content-Language: zh-CN
Transfer-Encoding: chunked
Date: Sun, 10 Dec 2017 07:13:55 GMT
Connection: close

{"timestamp":1512890035907,"status":500,"error":"Internal Server Error","exception":"org.springframework.expression.spel.SpelEvaluationException","message":"EL1008E: Property or field 'authorizationRequest' cannot be found on object of type 'java.util.HashMap' - maybe not public?","path":"/oauth/confirm_access"}

/oauth/error

这个可以不用认证保护

basic认证保护的源码

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

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        AuthorizationServerSecurityConfigurer configurer = new AuthorizationServerSecurityConfigurer();
        FrameworkEndpointHandlerMapping handlerMapping = endpoints.oauth2EndpointHandlerMapping();
        http.setSharedObject(FrameworkEndpointHandlerMapping.class, handlerMapping);
        configure(configurer);
        http.apply(configurer);
        String tokenEndpointPath = handlerMapping.getServletPath("/oauth/token");
        String tokenKeyPath = handlerMapping.getServletPath("/oauth/token_key");
        String checkTokenPath = handlerMapping.getServletPath("/oauth/check_token");
        if (!endpoints.getEndpointsConfigurer().isUserDetailsServiceOverride()) {
            UserDetailsService userDetailsService = http.getSharedObject(UserDetailsService.class);
            endpoints.getEndpointsConfigurer().userDetailsService(userDetailsService);
        }
        // @formatter:off
        http
            .authorizeRequests()
                .antMatchers(tokenEndpointPath).fullyAuthenticated()
                .antMatchers(tokenKeyPath).access(configurer.getTokenKeyAccess())
                .antMatchers(checkTokenPath).access(configurer.getCheckTokenAccess())
        .and()
            .requestMatchers()
                .antMatchers(tokenEndpointPath, tokenKeyPath, checkTokenPath)
        .and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.NEVER);
        // @formatter:on
        http.setSharedObject(ClientDetailsService.class, clientDetailsService);
    }

其中，可以自己指定check_token的认证级别，而/oauth/token则需要fullyAuthenticated token_key这个是jwt特有的，这里忽略不讲

isAuthenticated()与isFullyAuthenticated的区别

一个是authenticated，一个是fullyAuthenticated，前者排除anonymous，后者排除anonymous以及remember-me

isAuthenticated() Returns true if the user is not anonymous
isFullyAuthenticated() Returns true if the user is not an anonymous or a remember-me user

小结

综上，需要保护/oauth/authorize以及/oauth/confirm_access这两个endpoint，当然主要是/oauth/authorize这个。

由于其他几个/oauth/开头的认证endpoint配置的认证优先级高于默认的WebSecurityConfigurerAdapter配置(order=100)，因此默认的可以这样配置

@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        http
                .requestMatchers().antMatchers("/oauth/**","/login/**","/logout/**")
                .and()
                .authorizeRequests()
                .antMatchers("/oauth/**").authenticated()
                .and()
                .formLogin().permitAll(); //新增login form支持用户登录及授权
    }
}

把整个/oauth/**保护进来
