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 xxxx，OAuth2AuthenticationProcessingFilter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。
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。
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<String> headerNameSet;
@Override
public Enumeration<String> getHeaderNames() {
if (headerNameSet == null) {
// first time this method is called, cache the wrapped request‘s header names:
headerNameSet = new HashSet<>();
Enumeration<String> wrappedHeaderNames = super.getHeaderNames();
while (wrappedHeaderNames.hasMoreElements()) {
String headerName = wrappedHeaderNames.nextElement();
if (!"Authorization".equalsIgnoreCase(headerName)) {
headerNameSet.add(headerName);
}
}
}
return Collections.enumeration(headerNameSet);
}
@Override
public Enumeration<String> getHeaders(String name) {
if ("Authorization".equalsIgnoreCase(name)) {
return Collections.<String>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);
}
}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);
}
} @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
}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);
}Authorization bearer xxx 11后面随机跟了两个参数
