Spring Oauth2 中的 CORS 错误

Question

我正在使用 Spring 安全性和 Oauth2。但是我是 Spring Oauth2 的新手，当前端访问资源时出现 CORS 错误。

我正在使用以下过滤器来允许其他域访问资源：

@Component
@Order(Integer.MAX_VALUE)
public class SimpleCORSFilter implements Filter {

    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Credentials", "True");
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization");
        chain.doFilter(req, res);
    }


    public void init(FilterConfig filterConfig) {}
    public void destroy() {}

}

我编写了以下代码以允许在我的 SecurityConfiguration.java 中使用公共资源。

@Override
protected void configure(HttpSecurity http) throws Exception {
             http
        .authorizeRequests().antMatchers("/social/facebook/**","/register/**","/public/**").permitAll().and()
        .authorizeRequests().antMatchers("/user/**").hasRole("USER").and()           
        .exceptionHandling()
            .accessDeniedPage("/login.jsp?authorization_error=true")
            .and()
        .csrf()
            .requireCsrfProtectionMatcher(new AntPathRequestMatcher("/oauth/authorize")).disable();

}

对于 Oauth2，以下代码用于保护我的 OAuth2ServerConfig.java 中的用户资源。

@Override
    public void configure(HttpSecurity http) throws Exception {
        http

            .requestMatchers().antMatchers("/user/**")
        .and()
            .authorizeRequests()
            .antMatchers("/user/**").access("#oauth2.hasScope('read')")
                .regexMatchers(HttpMethod.DELETE, "/oauth/users/([^/].*?)/tokens/.*")
                    .access("#oauth2.clientHasRole('ROLE_CLIENT') and (hasRole('ROLE_USER') or #oauth2.isClient()) and #oauth2.hasScope('write')")
                .regexMatchers(HttpMethod.GET, "/oauth/clients/([^/].*?)/users/.*")
                    .access("#oauth2.clientHasRole('ROLE_CLIENT') and (hasRole('ROLE_USER') or #oauth2.isClient()) and #oauth2.hasScope('read')")
                .regexMatchers(HttpMethod.GET, "/oauth/clients/.*")
                    .access("#oauth2.clientHasRole('ROLE_CLIENT') and #oauth2.isClient() and #oauth2.hasScope('read')");
    }

当我在浏览器中打开 index.html 文件时，如下所示：（对不起，我没有至少 10 个发布图片的声誉，所以我在这里粘贴链接）

它成功获取了公共数据，这意味着允许其他域访问“/public/**”数据。

但它无法获取“/user/**”数据（受 Oauth2 保护）。它给了我下面的错误提示“跨源请求被阻止”。

当我将前端文件移动到 Spring 服务器的同一个域时。它可以很好地获取“公共”和“用户”数据，如下所示：

前端和后端应该分开。但是 CORS 被阻止访问投影数据。谁能给我一些建议？非常感谢。我猜过滤器在 Oauth2 上不起作用？仍然花费大量时间寻找解决方案。

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)

public class SimpleCORSFilter implements Filter {

    @Override
    public void init(FilterConfig fc) throws ServletException {
    }

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

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

    }

    @Override
    public void destroy() {
    }

}

我将标头添加到端点

@Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints)
            throws Exception {

        endpoints.addInterceptor(new HandlerInterceptorAdapter() {
            @Override
            public boolean preHandle(HttpServletRequest hsr, HttpServletResponse rs, Object o) throws Exception {
                rs.setHeader("Access-Control-Allow-Origin", "*");
                rs.setHeader("Access-Control-Allow-Methods", "GET,POST,OPTIONS");
                rs.setHeader("Access-Control-Max-Age", "3600");
                rs.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization");
                return true;
            }
        });


    }
