禁用URL Spring Security Java配置的X-FrameOptions响应标头

Question

我试图禁用或将XframeOptions标头设置为使用Spring Security的Spring Boot Project中的特定URL same_origin。我粘贴了下面的代码，

@Configuration
@EnableWebSecurity    
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {    
    @Override
    protected void configure(HttpSecurity http) throws Exception {            
        RequestMatcher matcher = new AntPathRequestMatcher("**/course/embed/**");
        DelegatingRequestMatcherHeaderWriter headerWriter =
                new DelegatingRequestMatcherHeaderWriter(matcher,new XFrameOptionsHeaderWriter());
        http.headers()
                .frameOptions().sameOrigin()
                .addHeaderWriter(headerWriter);
    }    
}

我正在使用antrequestMatcher，但这不起作用，而是禁用所有响应的XframeOptions标头。有一个更好的方法吗？请帮助。

您需要配置多个httpsecurity实例。关键是多次扩展WebsEcurityConfigurationAdapter。例如，以下是一个与**/course/embed/**匹配的URL配置不同的示例。如果匹配X-Frame-Options将是Sameorigin，则否则。

@EnableWebSecurity
public class WebMVCSecurity {
    //Configure Authentication as normal, optional, showing just as a sample to indicate you can add other config like this
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("user").password("password").roles("USER").and()
                .withUser("admin").password("password").roles("USER", "ADMIN");
    }
    // Create an instance of WebSecurityConfigurerAdapter that contains @Order to specify which WebSecurityConfigurerAdapter should be considered first.
    @Configuration
    @Order(1)
    public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
        protected void configure(HttpSecurity http) throws Exception {
            // The http.antMatcher states that this HttpSecurity will only be applicable to URLs that match with **/course/embed/**
            http.antMatcher("**/course/embed/**").headers().frameOptions().sameOrigin();
        }
    }
    // Create another instance of WebSecurityConfigurerAdapter. 
    // If the URL does not match with **/course/embed/** this configuration will be used. 
    // This configuration is considered after ApiWebSecurityConfigurationAdapter since it has an @Order value after 1 (no @Order defaults to last).
    @Configuration
    public static class FormLoginWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests()
                    .anyRequest().authenticated()
                    .and()
                    .formLogin();
            //bla bla bla ...
        }
    }
}

另一个选项是：

1. 禁用使用XFrameOptionsHeaderWriter将X-Frame-Options添加到响应的默认弹簧安全
2. 配置一个新的头曲线，它仅将您实际需要X框架的路径委派给XFrameOptionsHeaderWriter

示例代码：

public class AlignSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception
    {
      http.headers()
        .frameOptions().disable()
        .addHeaderWriter(new CustomXFrameOptionsHeaderWriter());
    }
    private static class CustomXFrameOptionsHeaderWriter implements HeaderWriter {
        private final XFrameOptionsHeaderWriter defaultHeaderWriter;
        
        private static final Set<String> ALLOWED_TO_EMBED_IN_IFRAME = ImmutableSet.of("/some/path");
    
        public CustomXFrameOptionsHeaderWriter()
        {
            this.defaultHeaderWriter = new XFrameOptionsHeaderWriter(XFrameOptionsMode.DENY);
        }
        
        @Override
        public void writeHeaders(HttpServletRequest request, HttpServletResponse response)
        {
            if (!ALLOWED_TO_EMBED_IN_IFRAME.contains(request.getRequestURI()))
            {
                defaultHeaderWriter.writeHeaders(request, response);
            }
        }
    } 
}
