前言
上一篇博客简析了一下spring security oauth中生成AccessToken的源码，目的就是为了方便我们将原有的表单登录，短信登录以及社交登录的认证方法，都改造成基于AccessToken的认证方式
基于token的表单登录
在简析了spring security oauth的源码之后，我们发现，其实有些源码我们并不能用，至少，TokenEndPoint这个组件，我们就没法用，因为这个组件只会响应/oauth/token的请求，而且spring security oauth会根据OAuth协议中常用的4种授权模式去生成令牌，而我们这里是自定义的登录，自然用不上OAuth协议中的授权模式，因此我们改造自定义的登录，只能借鉴其令牌生成方式。
如果有印象，在前几篇博客中总结过自定义登录成功处理的方式，无论前面登录逻辑如何认证，我们只需要在认证成功之后，自定义生成AccessToken 即可，因此我们只需要重新处理我们自定义登录成功的处理方式即可。
那么如何处理，依旧是一个问题，这就回到了上一篇博客中的内容，构造AccessToken需要OAuth2Request和Authentication，其中Authentication是登录成功后的认证详情信息，在登录成功处理器中，会有相关参数传递进来。OAuth2Request由ClientDeatails和TokenRequest组成，这在上一篇博客中我们已经总结过了，ClientDetails根据传递参数中的ClientId和clientSecret等client配置信息组成，TokenRequest则由请求中其他参数实例化而成，具体如下图所示
相关改造代码如下
/**

*/
@Component("selfAuthenticationSuccessHandler")
@Slf4j
public class SelfAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {
@Autowired
private SecurityProperties securityProperties;
@Autowired

String clientSecret = tokens[1];
//得到clientDeatils信息

throw new UnapprovedClientAuthenticationException("clientid对应的信息不存在" + clientId);
} else if (!StringUtils.equals(clientSecret, clientDetails.getClientSecret())) {

//构建自己的tokenRequest，由于这里不能使用OAuth2中的四种授权模式，因此这里第四个参数设置为"customer"
//同理，第一个参数主要用于组装并生成Authentication，而这里的Authentication已经通过参数传递进来，因此可以直接赋一个空的Map

基于token的短信验证码登录
之前提到过，由于基于token的认证交互，其实不一定会有session会话的概念，如果我们的验证码依旧存于session中，则并不能正常校验，因此在基于token的短信验证码登录的重构中，我们唯一要做的，就是将验证码存于Redis等缓存中间件中，验证码的key值为deviceid。
方案比较简单，这里只贴出Redis操作验证码的方法
/**
* 基于redis的验证码存取器，避免由于没有session导致无法存取验证码的问题
*/
@Component
public class RedisValidateCodeRepository implements ValidateCodeRepository {
@Autowired
private RedisTemplate<Object, Object> redisTemplate;
/*

*/
@Override
public void save(ServletWebRequest request, ValidateCode code, ValidateCodeType type) {
redisTemplate.opsForValue().set(buildKey(request, type), code, 30, TimeUnit.MINUTES);
}
/*
* (non-Javadoc)
*/
@Override
public ValidateCode get(ServletWebRequest request, ValidateCodeType type) {
Object value = redisTemplate.opsForValue().get(buildKey(request, type));
if (value == null) {
return null;
}
return (ValidateCode) value;
}
/*
* (non-Javadoc)
*
*/
@Override
public void remove(ServletWebRequest request, ValidateCodeType type) {
redisTemplate.delete(buildKey(request, type));
}
/**

*/
private String buildKey(ServletWebRequest request, ValidateCodeType type) {
String deviceId = request.getHeader("deviceId");
if (StringUtils.isBlank(deviceId)) {
throw new ValidateCodeException("请在请求头中携带deviceId参数");
}
return "code:" + type.toString().toLowerCase() + ":" + deviceId;
}
}
基于token的社交登录
在调通微信社交登录之后，再进行总结，只是需要明确的是，这里分为两种情况，一种是简化模式，一种是标准的OAuth2授权模式（这两种的区别，在QQ登录和微信登录流程中有详细的体现）。
简化的OAuth的授权改造
简化的OAuth模式，OAuth协议简化的认证模式，与标准最大的不同，其实就是在获取授权码的时候，顺带将openId（第三方用户id）和accessToken（获取用户信息的令牌），在这种前后端彻底分离的架构中，前三步前端可以通过服务提供商的SDK完成openId和AccessToken的获取。但是并不能根据openId作为我们自己登录系统凭证，因此我们需要提供一个根据openId进行登录的方式这个与之前短信登录方式大同小异
1、OpenIdAuthenticationToken
/**
* autor:liman
* createtime:2021/8/4
* comment:OpenIdAuthenticationToken
*/
public class OpenIdAuthenticationToken extends AbstractAuthenticationToken {
private static final long serialVersionUID = SpringSecurityCoreVersion.SERIAL_VERSION_UID;
private final Object principal;
private String providerId;
/**
openId，和providerId作为principal
*/
public OpenIdAuthenticationToken(String openId, String providerId) {
super(null);
this.principal = openId;
this.providerId = providerId;
setAuthenticated(false);
}
/**
* This constructor should only be used by <code>AuthenticationManager</code> or
* <code>AuthenticationProvider</code> implementations that are satisfied with
* producing a trusted (i.e. {@link #isAuthenticated()} = <code>true</code>)
* authentication token.
*
* @param principal
* @param credentials
* @param authorities
*/
public OpenIdAuthenticationToken(Object principal,
Collection<? extends GrantedAuthority> authorities) {
super(authorities);
this.principal = principal;
super.setAuthenticated(true); // must use super, as we override
}
public Object getCredentials() {
return null;
}
public Object getPrincipal() {
return this.principal;
}
public String getProviderId() {
return providerId;
}
public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {
if (isAuthenticated) {
throw new IllegalArgumentException(
"Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead");
}
super.setAuthenticated(false);
}
@Override
public void eraseCredentials() {
super.eraseCredentials();
}
}
2、OpenIdAuthenticationFilter
/**
* autor:liman
* createtime:2021/8/4
* comment:基于openId登录的过滤器
*/
@Slf4j
public class OpenIdAuthenticationFilter extends AbstractAuthenticationProcessingFilter {
private String openIdParameter = "openId";
private String providerIdParameter = "providerId";
private boolean postOnly = true;
public OpenIdAuthenticationFilter() {
super(new AntPathRequestMatcher("/authentication/openid", "POST"));
}
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
throws AuthenticationException {
if (postOnly && !request.getMethod().equals("POST")) {
throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());
}
//获取请求中的openId和providerId
String openid = obtainOpenId(request);
String providerId = obtainProviderId(request);
if (openid == null) {
openid = "";
}
if (providerId == null) {
providerId = "";
}
openid = openid.trim();
providerId = providerId.trim();
//构造OpenIdAuthenticationToken
OpenIdAuthenticationToken authRequest = new OpenIdAuthenticationToken(openid, providerId);
// Allow subclasses to set the "details" property
setDetails(request, authRequest);
//交给AuthenticationManager进行认证
return this.getAuthenticationManager().authenticate(authRequest);
}
/**
* 获取openId
*/
protected String obtainOpenId(HttpServletRequest request) {
return request.getParameter(openIdParameter);
}
/**
* 获取提供商id
*/
protected String obtainProviderId(HttpServletRequest request) {
return request.getParameter(providerIdParameter);
}
protected void setDetails(HttpServletRequest request, OpenIdAuthenticationToken authRequest) {
authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
}
public void setOpenIdParameter(String openIdParameter) {
Assert.hasText(openIdParameter, "Username parameter must not be empty or null");
this.openIdParameter = openIdParameter;
}
public void setPostOnly(boolean postOnly) {
this.postOnly = postOnly;
}
public final String getOpenIdParameter() {
return openIdParameter;
}
public String getProviderIdParameter() {
return providerIdParameter;
}
public void setProviderIdParameter(String providerIdParameter) {
this.providerIdParameter = providerIdParameter;
}
}
3、OpenIdAuthenticationProvider
/**
*
*/
package com.learn.springsecurity.app.social.openid;
/**
* @author zhailiang
*
*/
public class OpenIdAuthenticationProvider implements AuthenticationProvider {
private SocialUserDetailsService userDetailsService;
private UsersConnectionRepository usersConnectionRepository;
/*
* (non-Javadoc)
*
* @see org.springframework.security.authentication.AuthenticationProvider#
* authenticate(org.springframework.security.core.Authentication)
*/
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
OpenIdAuthenticationToken authenticationToken = (OpenIdAuthenticationToken) authentication;
Set<String> providerUserIds = new HashSet<>();
providerUserIds.add((String) authenticationToken.getPrincipal());
//之前社交登录中介绍的usersConnectionRepository，从user_connection表中根据providerId和openId查询用户id
Set<String> userIds = usersConnectionRepository.findUserIdsConnectedTo(authenticationToken.getProviderId(), providerUserIds);
if(CollectionUtils.isEmpty(userIds) || userIds.size() != 1) {
throw new InternalAuthenticationServiceException("无法获取用户信息");
}
//获取到userId了
String userId = userIds.iterator().next();
//利用UserDetailsService根据userId查询用户信息
UserDetails user = userDetailsService.loadUserByUserId(userId);
if (user == null) {
throw new InternalAuthenticationServiceException("无法获取用户信息");
}
OpenIdAuthenticationToken authenticationResult = new OpenIdAuthenticationToken(user, user.getAuthorities());
authenticationResult.setDetails(authenticationToken.getDetails());
return authenticationResult;
}
/*
* (non-Javadoc)
*
* @see org.springframework.security.authentication.AuthenticationProvider#
* supports(java.lang.Class)
*/
@Override
public boolean supports(Class<?> authentication) {
return OpenIdAuthenticationToken.class.isAssignableFrom(authentication);
}
public SocialUserDetailsService getUserDetailsService() {
return userDetailsService;
}
public void setUserDetailsService(SocialUserDetailsService userDetailsService) {
this.userDetailsService = userDetailsService;
}
public UsersConnectionRepository getUsersConnectionRepository() {
return usersConnectionRepository;
}
public void setUsersConnectionRepository(UsersConnectionRepository usersConnectionRepository) {
this.usersConnectionRepository = usersConnectionRepository;
}
}
4、配置类
/**
* @author zhailiang
*
*/
@Component
public class OpenIdAuthenticationSecurityConfig extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {
@Autowired
private AuthenticationSuccessHandler selfAuthenticationSuccessHandler;
@Autowired
private AuthenticationFailureHandler selfAuthenticationFailureHandler;
@Autowired
private SocialUserDetailsService userDetailsService;
@Autowired
private UsersConnectionRepository usersConnectionRepository;
@Override
public void configure(HttpSecurity http) throws Exception {
OpenIdAuthenticationFilter OpenIdAuthenticationFilter = new OpenIdAuthenticationFilter();
OpenIdAuthenticationFilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class));
OpenIdAuthenticationFilter.setAuthenticationSuccessHandler(selfAuthenticationSuccessHandler);
OpenIdAuthenticationFilter.setAuthenticationFailureHandler(selfAuthenticationFailureHandler);
OpenIdAuthenticationProvider OpenIdAuthenticationProvider = new OpenIdAuthenticationProvider();
OpenIdAuthenticationProvider.setUserDetailsService(userDetailsService);
OpenIdAuthenticationProvider.setUsersConnectionRepository(usersConnectionRepository);
http.authenticationProvider(OpenIdAuthenticationProvider)
.addFilterAfter(OpenIdAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
}
}
测试结果
标准的OAuth授权改造
标准的OAuth模式
针对标准的授权模式，我们并不需要做多少改动，因为在社交登录那一节中我们已经做了相关开发，只是需要说明的是，只是在spring-social的过滤器――SocialAuthenticationFilter中，在正常社交登录流程完成之后会默认跳转到某个页面，而这个并不适用于前后端分离的项目，因此要针对这个问题定制化解决。这需要回到之前SocialAuthenticationFilter加入到认证过滤器链上的代码。之前我们说过社交登录的过滤器链不需要我们手动配置，只需要初始化SpringSocialConfiguer的时候，会自动加入到社交登录的认证过滤器链上
@Configuration
@EnableSocial
public class SocialConfig extends SocialConfigurerAdapter {
@Bean
public SpringSocialConfigurer selfSocialSecurityConfig(){
SpringSocialConfigurer selfSpringSocialConfig = new SpringSocialConfigurer();
return selfSpringSocialConfig;
}
}
我们只需要改变SocialAuthenticationFilter的默认处理即可，因此我们给他加一个后置处理器，但是这个后置处理器是在SpringSocialConfigurer的postProcess函数中进行处理
/**
* autor:liman
* createtime:2021/7/15
* comment:自定义的springsocial配置类
*/
public class SelfSpringSocialConfig extends SpringSocialConfigurer {
private String processFilterUrl;
@Autowired(required = false)
private ConnectionSignUp connectionSignUp;
@Autowired(required = false)
private SocialAuthenticationFilterPostProcessor socialAuthenticationFilterPostProcessor;
public SelfSpringSocialConfig(String processFilterUrl) {
this.processFilterUrl = processFilterUrl;
}
@Override
protected <T> T postProcess(T object) {
SocialAuthenticationFilter socialAuthenticationFilter = (SocialAuthenticationFilter) super.postProcess(object);
socialAuthenticationFilter.setFilterProcessesUrl(processFilterUrl);
if(null!=socialAuthenticationFilterPostProcessor){
socialAuthenticationFilterPostProcessor.process(socialAuthenticationFilter);
}
return (T) socialAuthenticationFilter;
}
public ConnectionSignUp getConnectionSignUp() {
return connectionSignUp;
}
public void setConnectionSignUp(ConnectionSignUp connectionSignUp) {
this.connectionSignUp = connectionSignUp;
}
public SocialAuthenticationFilterPostProcessor getSocialAuthenticationFilterPostProcessor() {
return socialAuthenticationFilterPostProcessor;
}
public void setSocialAuthenticationFilterPostProcessor(SocialAuthenticationFilterPostProcessor socialAuthenticationFilterPostProcessor) {
this.socialAuthenticationFilterPostProcessor = socialAuthenticationFilterPostProcessor;
}
}
//将我们自定义的 SpringSocialConfigurer交给spring托管
@Configuration
@EnableSocial
public class SocialConfig extends SocialConfigurerAdapter {
@Bean
public SpringSocialConfigurer selfSocialSecurityConfig(){
String processFilterUrl = securityProperties.getSocial().getProcessFilterUrl();
SelfSpringSocialConfig selfSpringSocialConfig = new SelfSpringSocialConfig(processFilterUrl);
//指定第三方用户信息认证不存在的注册页
selfSpringSocialConfig.signupUrl(securityProperties.getBrowser().getSiguUpPage());
selfSpringSocialConfig.setConnectionSignUp(connectionSignUp);
selfSpringSocialConfig.setSocialAuthenticationFilterPostProcessor(socialAuthenticationFilterPostProcessor);
return selfSpringSocialConfig;
}
}
我们自定义的过滤器后置处理器如下
/**
* autor:liman
* createtime:2021/8/7
* comment:APP社交登录认证后置处理器
*/
@Component
public class AppSocialAuthenticationFilterPostProcessor implements SocialAuthenticationFilterPostProcessor {
@Autowired
private AuthenticationSuccessHandler selfAuthenticationSuccessHandler;
@Override
public void process(SocialAuthenticationFilter socialAuthenticationFilter) {
socialAuthenticationFilter.setAuthenticationSuccessHandler(selfAuthenticationSuccessHandler);
}
}
关于用户的绑定
这里需要总结一下之前的社交登录中用户注册绑定的操作。
之前的社交登录绑定用户
在之前的社交登录中，如果spring social发现用户是第一次登录，则会跳转到相关的页面，这个页面我们其实也可以自己定义并配置
@Configuration
@EnableSocial
public class SocialConfig extends SocialConfigurerAdapter {
@Bean
public SpringSocialConfigurer selfSocialSecurityConfig(){
String processFilterUrl = securityProperties.getSocial().getProcessFilterUrl();
SelfSpringSocialConfig selfSpringSocialConfig = new SelfSpringSocialConfig(processFilterUrl);
//指定第三方用户信息认证不存在的注册页
selfSpringSocialConfig.signupUrl(securityProperties.getBrowser().getSiguUpPage());
selfSpringSocialConfig.setConnectionSignUp(connectionSignUp);
selfSpringSocialConfig.setSocialAuthenticationFilterPostProcessor(socialAuthenticationFilterPostProcessor);
return selfSpringSocialConfig;
}
@Bean
public ProviderSignInUtils providerSignInUtils(ConnectionFactoryLocator connectionFactoryLocator){
return new ProviderSignInUtils(connectionFactoryLocator,
getUsersConnectionRepository(connectionFactoryLocator));
}
}
我们配置的代码中，可以自定义页面路径，我们自定义页面如下（一个简单的登录绑定页面）
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>登录</title> </head> <body> <h2>Demo注册页</h2> <form action="user/regist" method="post"> <table> <tr> <td>用户名:</td> <td><input type="text" name="username"></td> </tr> <tr> <td>密码:</td> <td><input type="password" name="password"></td> </tr> <tr> <td colspan="2"> <button type="submit" name="type" value="regist">注册</button> <button type="submit" name="type" value="binding">绑定</button> </td> </tr> </table> </form> </body> </html>
在用户第一次跳转到这个页面的用户选择注册，或者绑定，都会请求/user/register接口，这个接口借助providerSignInUtils完成会话中的用户数据更新
@Autowired
private ProviderSignInUtils providerSignInUtils;
@PostMapping("/register")
public void userRegister(@RequestBody User user, HttpServletRequest request) {
//利用providerSignInUtils，将注册之后的用户信息，关联到会话中
providerSignInUtils.doPostSignUp(user.getId(),new ServletWebRequest(request));
}
在跳转之前，spring social已经帮我们将用户信息存入会话（在SocialAuthenticationFilter中可以看到相关代码）
//以下代码位于：org.springframework.social.security.SocialAuthenticationFilter#doAuthentication
private Authentication doAuthentication(SocialAuthenticationService<?> authService, HttpServletRequest request, SocialAuthenticationToken token) {
try {
if (!authService.getConnectionCardinality().isAuthenticatePossible()) return null;
token.setDetails(authenticationDetailsSource.buildDetails(request));
Authentication success = getAuthenticationManager().authenticate(token);
Assert.isInstanceOf(SocialUserDetails.class, success.getPrincipal(), "unexpected principle type");
updateConnections(authService, token, success);
return success;
} catch (BadCredentialsException e) {
// connection unknown, register new user?
if (signupUrl != null) {
//这里就是将社交用户信息存入会话
// store ConnectionData in session and redirect to register page
sessionStrategy.setAttribute(new ServletWebRequest(request), ProviderSignInAttempt.SESSION_ATTRIBUTE, new ProviderSignInAttempt(token.getConnection()));
throw new SocialAuthenticationRedirectException(buildSignupUrl(request));
}
throw e;
}
}
但是基于前后端分离，且并没有会话对象交互的系统，这种方式并不适用，因为并不存在会话，如何处理，需要用其他方案，其实我们可以在验证码登录的改造中受到启发，将用户数据存入会话即可，我们自定义实现一个providerSignInUtils将用户信息存入Redis即可。
自定义providerSignUtils
1、将第三方用户数据存入Redis的工具类
/**
* autor:liman
* createtime:2021/8/7
* comment:app端用户信息存入Redis的工具类
*/
@Component
public class AppSignUpUtils {
public static final String SOCIAL_REDIS_USER_PREFIX = "self:security:social:connectionData";
@Autowired
private RedisTemplate<Object, Object> redisTemplate;
@Autowired
private UsersConnectionRepository usersConnectionRepository;
@Autowired
private ConnectionFactoryLocator connectionFactoryLocator;
public void saveConnectionData(WebRequest webRequest, ConnectionData connectionData) {
redisTemplate.opsForValue().set(getKey(webRequest), connectionData, 10, TimeUnit.MINUTES);
}
/**
* 将用户与数据库中的信息进行绑定
* @param request
* @param userId
*/
public void doPostSignUp(WebRequest request,String userId){
String key = getKey(request);
if(!redisTemplate.hasKey(key)){
throw new RuntimeException("无法找到缓存的用户社交账号信息");
}
ConnectionData connectionData = (ConnectionData) redisTemplate.opsForValue().get(key);
//根据ConnectionData实例化创建一个Connection
Connection<?> connection = connectionFactoryLocator.getConnectionFactory(connectionData.getProviderId())
.createConnection(connectionData);
//将数据库中的用户与Redis中的用户信息关联
usersConnectionRepository.createConnectionRepository(userId).addConnection(connection);
}
/**
* 获取设备id作为key
*
* @param webRequest
* @return
*/
public String getKey(WebRequest webRequest) {
String deviceId = webRequest.getHeader("deviceId");
if (StringUtils.isBlank(deviceId)) {
throw new RuntimeException("设备id不能为空");
}
return SOCIAL_REDIS_USER_PREFIX + deviceId;
}
}
2、复写掉原来的配置类
为了避免对原有代码的侵入性处理，这里我们需要自定义一个实现BeanPostProcessor接口的类
/**
* autor:liman
* createtime:2021/8/7
* comment:由于app端的社交用户绑定，不能采用跳转，也不能操作会话，需要用自定义的providerSignUpUtils工具类
* 因此需要定义一个后置处理器，针对SpringSocialConfigurer进行一些后置处理
*/
@Component
public class AppSpringSocialConfigurerPostProcessor implements BeanPostProcessor {
@Override
public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
return null;
}
@Override
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
if(StringUtils.equals(beanName,"selfSocialSecurityConfig")){
SelfSpringSocialConfig configurer = (SelfSpringSocialConfig) bean;
//复写掉原有的SelfSpringSocialConfig的signupUrl
configurer.signupUrl("/app/social/signup");
return configurer;
}
return bean;
}
}
针对上述的请求路径，我们也要写一个对应路径的controller处理方法
@RestController
@Slf4j
public class AppSecurityController {
@Autowired
private ProviderSignInUtils providerSignInUtils;
@Autowired
private AppSignUpUtils appSignUpUtils;
@GetMapping("/app/social/signup")
@ResponseStatus(HttpStatus.UNAUTHORIZED)
public BaseResponse getSocialUserInfo(HttpServletRequest request){
BaseResponse result = new BaseResponse(StatusCode.Success);
log.info("【app模式】开始获取会话中的第三方用户信息");
//先从其中拿出数据，毕竟这个时候还没有完全跳转，下一个会话，就没有该数据了
Connection<?> connectionFromSession = providerSignInUtils.getConnectionFromSession(new ServletWebRequest(request));
SocialUserInfo socialUserInfo = new SocialUserInfo();
socialUserInfo.setProviderId(connectionFromSession.getKey().getProviderId());
socialUserInfo.setProviderUserId(connectionFromSession.getKey().getProviderUserId());
socialUserInfo.setNickName(connectionFromSession.getDisplayName());
socialUserInfo.setHeadImg(connectionFromSession.getImageUrl());
//转存到自己的工具类中
appSignUpUtils.saveConnectionData(new ServletWebRequest(request),connectionFromSession.createData());
result.setData(socialUserInfo);
return result;
}
}
对于用户注册的接口也需要做调整
@PostMapping("/register")
public void userRegister(@RequestBody User user, HttpServletRequest request) {
//如果是浏览器的应用利用providerSignInUtils，将注册之后的用户信息，关联到会话中
providerSignInUtils.doPostSignUp(user.getId(),new ServletWebRequest(request));
//如果是app的应用，则利用appSignUpUtils 将注册之后的用户信息，关联到会话中
appSignUpUtils.doPostSignUp(new ServletWebRequest(request),user.getId());
}
总结
