Spring + GraphQL - 可选授权

Question

我目前正在使用Spring Boot Starter和GraphQL Java Tools在我的 Spring 应用程序中使用 GraphQL。只要我授权 graphql 端点，它就可以与我的授权过滤器配合良好。现在我想向公众开放某些突变或查询（因此不需要授权），这就是我绊倒的地方。如何打开graphql端点但仍然能够使用@PreAuthorizeSpring security的注释进行方法级别授权？换句话说：是否可以在端点上进行“可选”授权？

这是我的配置：

@Override
protected void configure(HttpSecurity http) throws Exception {
    log.debug("configureHttpSecurity");

    // Only authorize the request if it is NOT in the permitAllEndpoints AND matches API_ROOT_URL OR
    // MESSAGING_ROOT_URL
    List<RequestMatcher> requestMatchers = new ArrayList<>();
    requestMatchers.add(new SkipPathRequestMatcher(permitAllEndpointList, API_ROOT_URL));
    requestMatchers.add(new AntPathRequestMatcher(MESSAGING_ROOT_URL));
    OrRequestMatcher apiMatcher = new OrRequestMatcher(requestMatchers);

    http.csrf().disable()
                .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            .and()
                .authorizeRequests()
                .antMatchers(permitAllEndpointList.toArray(new String[0]))
                .permitAll()
            .and()
                .authorizeRequests()
                .antMatchers(API_ROOT_URL, MESSAGING_ROOT_URL)
                .authenticated()
            .and()
                .addFilterBefore(new CustomCorsFilter(),
                        UsernamePasswordAuthenticationFilter.class)
                .addFilterBefore(new AuthenticationFilter(authenticationManager()),
                        UsernamePasswordAuthenticationFilter.class)
                .addFilterBefore(new AuthorizationFilter(apiMatcher),
                        UsernamePasswordAuthenticationFilter.class);
}

这apiMatcher是为了开放某些 REST 端点。这是我的AuthorizationFilter：

@Override
public Authentication attemptAuthentication(HttpServletRequest httpServletRequest,
                                            HttpServletResponse httpServletResponse)
        throws AuthenticationException, IOException, ServletException {
    try {
        String authorization = httpServletRequest.getHeader("Authorization");
        if (authorization != null && authorization.startsWith("Bearer ")) {
            return getAuthentication(authorization.replace("Bearer ", ""));
        }
    } catch (ExecutionException e) {
        httpServletResponse.sendError(HttpServletResponse.SC_FORBIDDEN,"The provided token was either not valid or is already expired!");
        return null;
    } catch (IOException | InterruptedException e) {
        httpServletResponse.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR,"There was a problem verifying the supplied token!");
        return null;
    }
    httpServletResponse.sendError(HttpServletResponse.SC_FORBIDDEN, "Unauthorized");
    return null;
}

如果我在末尾没有发送错误，attemptAuthentication我将能够访问不应该打开的 REST 端点。另外，如果我只允许 GraphQL 端点，则不会发生授权，因此@PreAuthorize即使我提供有效的 JWT，每个操作都会失败。也许我的做法已经是错误的了。如果是这种情况，请告诉我。

我通过使用两个安全配置解决了这个问题。一个用于我的 REST api，它强制执行身份验证/授权。另一个有一个可选的授权过滤器，它仅使用令牌（如果存在）。现在唯一的缺点是所有查询和突变默认情况下都是向公众开放的，需要注释@PreAuthorize来关闭。
