Spring Security Oauth2 permitAll()方法小记

黄鼠狼在养鸡场山崖边立了块碑,写道:“不勇敢地飞下去,你怎么知道自己原来是一只搏击长空的鹰?!”

从此以后

黄鼠狼每天都能在崖底吃到那些摔死的鸡!

前言

上周五有网友问道,在使用spring-security-oauth2时,虽然配置了.antMatchers("/permitAll").permitAll(),但如果在header 中 携带 Authorization Bearer xxxxOAuth2AuthenticationProcessingFilter还是会去校验Token的正确性,如果Token合法,可以正常访问,否则,请求失败。他的需求是当配置.permitAll()时,即使携带Token,也可以直接访问。

解决思路

根据Spring Security源码分析一:Spring Security认证过程得知spring-security的认证为一系列过滤器链。我们只需定义一个比OAuth2AuthenticationProcessingFilter更早的过滤器拦截指定请求,去除header中的Authorization Bearer xxxx即可。

代码修改

添加PermitAuthenticationFilter类

添加PermitAuthenticationFilter类拦截指定请求,清空header中的Authorization Bearer xxxx

@Component("permitAuthenticationFilter")
@Slf4j
public class PermitAuthenticationFilter extends OncePerRequestFilter {

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {

        log.info("当前访问的地址:{}", request.getRequestURI());
        if ("/permitAll".equals(request.getRequestURI())) {

            request = new HttpServletRequestWrapper(request) {
                private Set headerNameSet;

                @Override
                public Enumeration getHeaderNames() {
                    if (headerNameSet == null) {
                        // first time this method is called, cache the wrapped request's header names:
                        headerNameSet = new HashSet<>();
                        Enumeration wrappedHeaderNames = super.getHeaderNames();
                        while (wrappedHeaderNames.hasMoreElements()) {
                            String headerName = wrappedHeaderNames.nextElement();
                            if (!"Authorization".equalsIgnoreCase(headerName)) {
                                headerNameSet.add(headerName);
                            }
                        }
                    }
                    return Collections.enumeration(headerNameSet);
                }

                @Override
                public Enumeration getHeaders(String name) {
                    if ("Authorization".equalsIgnoreCase(name)) {
                        return Collections.emptyEnumeration();
                    }
                    return super.getHeaders(name);
                }

                @Override
                public String getHeader(String name) {
                    if ("Authorization".equalsIgnoreCase(name)) {
                        return null;
                    }
                    return super.getHeader(name);
                }
            };

        }
        filterChain.doFilter(request, response);

    }
}

复制代码

添加PermitAllSecurityConfig配置

添加PermitAllSecurityConfig配置用于配置PermitAuthenticationFilter

@Component("permitAllSecurityConfig")
public class PermitAllSecurityConfig extends SecurityConfigurerAdapter<DefaultSecurityFilterChain,HttpSecurity> {

    @Autowired
    private Filter permitAuthenticationFilter;

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.addFilterBefore(permitAuthenticationFilter, OAuth2AuthenticationProcessingFilter.class);
    }
}

复制代码

修改MerryyouResourceServerConfig,增加对制定路径的授权

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

        // @formatter:off
        http.formLogin()
                .successHandler(appLoginInSuccessHandler)//登录成功处理器
                .and()
                .apply(permitAllSecurityConfig)
                .and()
                .authorizeRequests()
                .antMatchers("/user").hasRole("USER")
                .antMatchers("/forbidden").hasRole("ADMIN")
                .antMatchers("/permitAll").permitAll()
                .anyRequest().authenticated().and()
                .csrf().disable();

        // @formatter:ON
    }
复制代码
  • 关于各个路径的说明参考:使用Spring MVC测试Spring Security Oauth2 API

修改测试类SecurityOauth2Test

添加permitAllWithTokenTest方法

    @Test
    public void permitAllWithTokenTest() throws Exception{
        final String accessToken = obtainAccessToken();
        log.info("access_token={}", accessToken);
        String content = mockMvc.perform(get("/permitAll").header("Authorization", "bearer " + accessToken+"11"))
                .andExpect(status().isOk())
                .andReturn().getResponse().getContentAsString();
        log.info(content);
    }
复制代码
  • Authorization bearer xxx 11后面随机跟了两个参数

效果如下

不配置permitAllSecurityConfig时
