spring - CORS 不适用于带有 OAuth2 的 Spring 4.3

Question

以下是我使用 Angular 1.5 应用程序发出请求时在 Chrome 控制台中得到的信息:

XMLHttpRequest cannot load http://localhost:8080/api/oauth/token. 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:8000' is therefore not allowed access. The response had HTTP status code 401.

当我删除 OAuth2 配置时，错误消失了。

这是我的 CORS 配置:

class AppWebSpringConfig extends WebMvcConfigurerAdapter implements ServletContextAware {

...

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowedMethods("GET", "POST", "PUT", "DELETE")
                .allowedHeaders("X-Requested-With", "X-Auth-Token", "Origin", "Content-Type", "Accept")
                .allowCredentials(false)
                .maxAge(3600);
    }

...
}

还有我的 OAuth2 配置类:

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {

    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        return new OAuth2MethodSecurityExpressionHandler();
    }

}

@Configuration
class OAuth2ServerConfiguration {

    private static final int ONE_HOUR = 3600;
    private static final int THIRTY_DAYS = 2592000;

    @Configuration
    @EnableResourceServer
    protected static class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

        @Override
        public void configure(HttpSecurity http) throws Exception {
            // @formatter:off
            http
                    .authorizeRequests()
                    .anyRequest().authenticated();
            // @formatter:on
        }

    }

    @Configuration
    @EnableAuthorizationServer
    protected static class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

        @Autowired
        @Qualifier("authenticationManagerBean")
        private AuthenticationManager authenticationManager;

        @Autowired
        private UserSecurityService userSecurityService;

        @Autowired
        private DataSource dataSource;

        @Autowired
        private Environment env;

        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
            // @formatter:off
            endpoints
                    .tokenStore(tokenStore())
                    .authenticationManager(authenticationManager)
                    .userDetailsService(userSecurityService);
            // @formatter:on
        }

        @Bean
        public TokenStore tokenStore() {
            return new JdbcTokenStore(dataSource);
        }

        @Override
        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
            // @formatter:off
            clients
                    .jdbc(dataSource)
                    .withClient(env.getProperty(CLIENT_ID_WEB))
                    .secret(env.getProperty(CLIENT_SECRET_WEB))
                    .authorizedGrantTypes("password", "refresh_token")
                    .scopes("read", "write")
                    .accessTokenValiditySeconds(ONE_HOUR)
                    .refreshTokenValiditySeconds(THIRTY_DAYS);
            // @formatter:on
        }

        @Bean
        @Primary
        public DefaultTokenServices tokenServices() {
            final DefaultTokenServices tokenServices = new DefaultTokenServices();
            tokenServices.setSupportRefreshToken(true);
            tokenServices.setTokenStore(tokenStore());
            return tokenServices;
        }

    }

}

编辑:我还尝试了以下过滤器实现，但它不起作用。我在 doFilter() 方法中放置了一个断点，但执行并没有在那里停止，就像我的过滤器没有注册一样。但是，当我向过滤器添加默认构造函数并在那里放置断点时，它停止了，这意味着过滤器已注册。

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class SimpleCorsFilter implements Filter {

    public SimpleCorsFilter() {
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        HttpServletRequest request = (HttpServletRequest) req;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with, authorization");

        if ("OPTIONS".equalsIgnoreCase(request.getMethod())) {
            response.setStatus(HttpServletResponse.SC_OK);
        } else {
            chain.doFilter(req, res);
        }
    }

    @Override
    public void init(FilterConfig filterConfig) {
    }

    @Override
    public void destroy() {
    }
}

我也尝试过这种方法，但再次没有运气:Allow OPTIONS HTTP Method for oauth/token request

我认为 OAuth2 配置不允许请求甚至通过配置的 CORS 过滤器。 有人知道这个问题的解决方案吗？

编辑2: 所以，原来有一个类:

public class AppSecurityInitializer extends AbstractSecurityWebApplicationInitializer {

    // nothing here, using defaults

}

一旦我评论它，CORS 配置就开始工作(可能是由于过滤器通过)，但现在我的 OAuth2 配置根本不起作用!每个 URL 都是公开的，没有安全性。有什么想法吗？

嗨，我在 spring 4.3 上遇到了同样的问题，但在这里解决了答案:-

您需要在 AuthorizationServerConfiguration 类中重写 AuthorizationServerConfigurerAdapter 的以下方法，并使用 AuthorizationServerSecurityConfigurer 的 addTokenEndpointAuthenticationFilter 方法在其中添加 CORS 过滤器，如下所示:-

 @Override
 public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
       security.addTokenEndpointAuthenticationFilter(new CORSFilter());
 }

您的 AuthorizationServerConfiguration 类将是:-

 @Configuration
    @EnableAuthorizationServer
    protected static class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

        @Autowired
        @Qualifier("authenticationManagerBean")
        private AuthenticationManager authenticationManager;

        @Autowired
        private UserSecurityService userSecurityService;

        @Autowired
        private DataSource dataSource;

        @Autowired
        private Environment env;

        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
            // @formatter:off
            endpoints
                    .tokenStore(tokenStore())
                    .authenticationManager(authenticationManager)
                    .userDetailsService(userSecurityService);
            // @formatter:on
        }

        @Bean
        public TokenStore tokenStore() {
            return new JdbcTokenStore(dataSource);
        }

        @Override
        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
            // @formatter:off
            clients
                    .jdbc(dataSource)
                    .withClient(env.getProperty(CLIENT_ID_WEB))
                    .secret(env.getProperty(CLIENT_SECRET_WEB))
                    .authorizedGrantTypes("password", "refresh_token")
                    .scopes("read", "write")
                    .accessTokenValiditySeconds(ONE_HOUR)
                    .refreshTokenValiditySeconds(THIRTY_DAYS);
            // @formatter:on
        }

        @Bean
        @Primary
        public DefaultTokenServices tokenServices() {
            final DefaultTokenServices tokenServices = new DefaultTokenServices();
            tokenServices.setSupportRefreshToken(true);
            tokenServices.setTokenStore(tokenStore());
            return tokenServices;
        }

        // ***** Here I added CORS filter *****
        @Override
        public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
              security.addTokenEndpointAuthenticationFilter(new CORSFilter());
        }  
}
