spring-security - 独立 Spring OAuth2 JWT 授权服务器 + CORS

Question

所以我有以下从 this example 浓缩的授权服务器来自戴夫·赛尔

@SpringBootApplication
public class AuthserverApplication {

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

    /* added later
    @Configuration
    @Order(Ordered.HIGHEST_PRECEDENCE)
    protected static class MyWebSecurity extends WebSecurityConfigurerAdapter {

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http //.csrf().disable() 
                .authorizeRequests()
                .antMatchers(HttpMethod.OPTIONS, "/oauth/token").permitAll();
       }
    }*/

    @Configuration
    @EnableAuthorizationServer
    protected static class OAuth2AuthorizationConfig extends
                    AuthorizationServerConfigurerAdapter {

            @Autowired
            private AuthenticationManager authenticationManager;

            @Bean
            public JwtAccessTokenConverter jwtAccessTokenConverter() {
                    JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
                    KeyPair keyPair = new KeyStoreKeyFactory(
                                    new ClassPathResource("keystore.jks"), "foobar".toCharArray())
                                    .getKeyPair("test");
                    converter.setKeyPair(keyPair);
                    return converter;
            }

            @Override
            public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
                    clients.inMemory()
                                    .withClient("acme")
                                    //.secret("acmesecret")
                                    .authorizedGrantTypes(//"authorization_code", "refresh_token",
                                                    "password").scopes("openid");
            }

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

            @Override
            public void configure(AuthorizationServerSecurityConfigurer oauthServer)
                            throws Exception {
                    oauthServer.tokenKeyAccess("permitAll()").checkTokenAccess(
                                    "isAuthenticated()");
            }
    }
}

当我运行它并用 curl 测试它时

curl acme@localhost:8110/oauth/token -d grant_type=password -d client_id=acme -d username=user -d password=password

我得到一个 JWT 作为响应，但是当我尝试从我的前端(不同端口上的 Angular JS)访问 AuthServer 时，我得到了 CORS 错误。不是因为缺少 header ，而是因为 OPTION 请求被拒绝并且缺少凭据。

Request URL:http://localhost:8110/oauth/token
Request Method:OPTIONS
Status Code:401 Unauthorized
WWW-Authenticate:Bearer realm="oauth", error="unauthorized", error_description="Full authentication is required to access this resource"

我已经知道我必须添加一个 CorsFilter 并且另外发现了 this post我使用第一个答案的片段来让 OPTIONS 请求访问 /oauth/token没有凭据:

@Order(-1)
public class MyWebSecurity extends WebSecurityConfigurerAdapter {
   @Override
   protected void configure(HttpSecurity http) throws Exception {
       http
          .authorizeRequests()
          .antMatchers(HttpMethod.OPTIONS, "/oauth/token").permitAll();
   }
}

之后，我得到了 curl 以下错误:

{"timestamp":1433370068120,"status":403,"error":"Forbidden","message":"Expected CSRF token not found. Has your session expired?","path":"/oauth/token"}

所以为了简单起见，我只是添加了 http.csrf().disable()到 configure MyWebSecurity 类的方法，它解决了 OPTION 请求的问题，但因此 POST 请求不再工作，我得到 There is no client authentication. Try adding an appropriate authentication filter. (也有 curl )。

我试图找出是否必须以某种方式连接 MyWebSecurity 类和 AuthServer，但没有任何运气。原始示例(开头的链接)也注入(inject)了 authenticationManager，但这对我来说没有任何改变。

Answer 1

找到了我的问题的原因!

如果 CorsFilter 处理了 OPTIONS 请求，我只需要结束过滤器链并立即返回结果!

SimpleCorsFilter.java

@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() {
    }
}

之后，我可以忽略 AuthServer =D 中的 OPTIONS 预检请求

所以服务器就像上面的截图一样工作，你可以在开始时忽略 MyWebSecurity 类的 block 注释。
