Spring启动安全性,Oauth2用来自facebook的长期令牌替换访问令牌
作者:互联网
我一直在关注Dave Syer astounding tutorial,在微服务中实现OAuth2,为移动设备(Android和iOS)提供RESTful API.我使用以下代码配置了网关安全性:
@SpringBootApplication
@EnableDiscoveryClient
@EnableZuulProxy
@EnableCircuitBreaker
@EnableFeignClients
@EnableOAuth2Client
public class GatewayApplication extends WebSecurityConfigurerAdapter {
private OAuth2ClientContext oauth2ClientContext;
private SimpleUrlAuthenticationSuccessHandler simpleUrlAuthenticationSuccessHandler;
private ScoreAuthorizationFilter scoreAuthorizationFilter;
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.antMatcher("/**")
.authorizeRequests()
.antMatchers("/", "/test", "/login**", "/webjars/**", "/error**")
.permitAll()
.anyRequest()
.authenticated()
.and().logout().logoutSuccessUrl("/").permitAll()
.and().addFilterBefore(ssoFilter(), BasicAuthenticationFilter.class)
.addFilterBefore(scoreAuthorizationFilter, BasicAuthenticationFilter.class)
;
}
private Filter ssoFilter() {
OAuth2ClientAuthenticationProcessingFilter facebookFilter = new OAuth2ClientAuthenticationProcessingFilter("/login/facebook");
OAuth2RestTemplate facebookTemplate = new OAuth2RestTemplate(facebook(), oauth2ClientContext);
facebookFilter.setRestTemplate(facebookTemplate);
UserInfoTokenServices tokenServices = new UserInfoTokenServices(facebookResource().getUserInfoUri(), facebook().getClientId());
tokenServices.setRestTemplate(facebookTemplate);
facebookFilter.setTokenServices(tokenServices);
facebookFilter.setAuthenticationSuccessHandler(simpleUrlAuthenticationSuccessHandler);
return facebookFilter;
}
@Bean
@ConfigurationProperties("facebook.client")
public AuthorizationCodeResourceDetails facebook() {
return new AuthorizationCodeResourceDetails();
}
@Bean
@ConfigurationProperties("facebook.resource")
public ResourceServerProperties facebookResource() {
return new ResourceServerProperties();
}
@Bean
public FilterRegistrationBean<OAuth2ClientContextFilter> oauth2ClientFilterRegistration(OAuth2ClientContextFilter filter) {
FilterRegistrationBean<OAuth2ClientContextFilter> registration = new FilterRegistrationBean<OAuth2ClientContextFilter>();
registration.setFilter(filter);
registration.setOrder(-100);
return registration;
}
@Bean
public RequestInterceptor getFeignClientInterceptor() {
return new FeignClientInterceptor();
}
}
事实证明,用户的会话在一段时间后过期.当我挖得更深一点时,我发现Facebook没有提供刷新令牌.相反,我们可以为一个长期存在的令牌交换一个短期令牌(Facebook long-lived token).如何覆盖Spring Security中实现的标准OAuth2流程,以便向Facebook发送另一个请求以获取长期存在的令牌,然后替换旧的访问令牌?
解决方法:
您可以通过扩展OAuth2ClientAuthenticationProcessingFilter类来实现您想要的效果,如下所示:
public class CustomAuthenticationProcessingFilter extends OAuth2ClientAuthenticationProcessingFilter {
private ResourceServerTokenServices tokenServices;
private AuthenticationDetailsSource<HttpServletRequest, ?> authenticationDetailsSource = new OAuth2AuthenticationDetailsSource();
private ApplicationEventPublisher eventPublisher;
private AuthorizationCodeResourceDetails facebook;
private String longLivedTokenUri;
public CustomAuthenticationProcessingFilter(String defaultFilterProcessesUrl) {
super(defaultFilterProcessesUrl);
setAuthenticationDetailsSource(authenticationDetailsSource);
}
@Override
public void setTokenServices(ResourceServerTokenServices tokenServices) {
this.tokenServices = tokenServices;
super.setTokenServices(tokenServices);
}
@Override
public void setApplicationEventPublisher(ApplicationEventPublisher eventPublisher) {
this.eventPublisher = eventPublisher;
super.setApplicationEventPublisher(eventPublisher);
}
@Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
throws AuthenticationException {
OAuth2AccessToken accessToken;
try {
accessToken = restTemplate.getAccessToken();
} catch (OAuth2Exception e) {
BadCredentialsException bad = new BadCredentialsException("Could not obtain access token", e);
publish(new OAuth2AuthenticationFailureEvent(bad));
throw bad;
}
String longLivedToken = getFromFacebook(); //Get long lived token from facebook here
try {
OAuth2Authentication result = tokenServices.loadAuthentication(longLivedToken);
if (authenticationDetailsSource != null) {
request.setAttribute(OAuth2AuthenticationDetails.ACCESS_TOKEN_VALUE, longLivedToken);
request.setAttribute(OAuth2AuthenticationDetails.ACCESS_TOKEN_TYPE, accessToken.getTokenType());
result.setDetails(authenticationDetailsSource.buildDetails(request));
}
publish(new AuthenticationSuccessEvent(result));
return result;
} catch (InvalidTokenException e) {
BadCredentialsException bad = new BadCredentialsException("Could not obtain user details from token", e);
publish(new OAuth2AuthenticationFailureEvent(bad));
throw bad;
}
}
private void publish(ApplicationEvent event) {
if (eventPublisher != null) {
eventPublisher.publishEvent(event);
}
}
}
我希望这有帮助.
