Spring Authorization Server基于Spring Session的前后端分离实现

ops/2024/10/30 22:37:51/

本章实现的效果

  1. 授权码模式下使用前后端分离的登录页面和授权确认页面。
  2. 设备码模式(Device Flow)下使用前后端分离的登录页面、授权确认页面、用户码(user_code)验证页面和用户码(user_code)验证成功页面。

前后端分离效果演示

分析

  在一年多以前我出了两篇前后端分离的文章，分别是《Spring Authorization Server入门 (十二) 实现授权码模式使用前后端分离的登录页面》和《Spring Authorization Server入门 (十五) 分离授权确认与设备码校验页面》，最开始我的想法就是在OAuth2登录前生成一个id，在OAuth2登录期间所有请求都携带着这个id，特别是前端提交登录时，后端根据这个id存储认证信息，然后等登录以后重定向会授权申请时授权申请也会带这个这个id，这样就可以获取到前端提交登录以后存储的认证信息，相当于前端、后端两条独立不相交的线通过这个id串联起来了，但是这样就会很麻烦，授权申请、授权确认等都需要带这个id，后来我观察到对于浏览器来说，访问认证服务相关端点时每次都是同一个Session，所以后来通过SessionId来代替前端生成的id，这样在请求时比前边方便很多，但是后端的一些自定义处理就不能出现一丝差错，错一点就达不到想要的效果；

  再后来有大佬提议可以使用Spring Session管理Session，打通前端、后端Session之间的壁垒，让他们直接可以互通，这样分离、不分离的唯一区别就是返回json和重定向的区别，那么在使用Spring Session的情况下仅需要自定义一些响应就差不多了，这种情况下出问题的概率就会很低了。

  但是Spring Session也是有一定限制的，它只能共享同一域名下不同子域名的Session，前端在提交登录或在OAuth2登录流程中有其它需要和认证服务交互的地方(ajax\axios)时需要添加跨域请求携带cookie配置，例如Axios需要在初始化时添加withCredentials: true配置使其在跨域请求时带上cookie，这样前后端之间的Session就只会有一个。

  Spring Session在只引入依赖时我测试时axios请求的ip、前端项目访问的ip保持一致就可以共享Session，如果在有域名代理的情况下如果不能共享Session，可以在application.yml中添加配置指定域名server.servlet.session.cookie.domain: 这里是具体的顶级域名，类似(xxx.com)，如果添加了该配置，那么配置的ip(域名)、axios请求的ip(域名)和访问前端项目的ip三者要保持一致。

实现步骤

  1. 添加Spring Session Data Redis依赖。
  2. 自定义登录成功、失败处理，在前后端分离时响应json，否则重定向。
  3. 自定义重定向至登录页面处理，在重定向至登录页面时将当前请求的请求路径挂在登录页面的target参数中，前端登录成功后直接跳转至target中挂的url。
  4. 自定义授权确认成功、失败处理，在前后端分离时响应json，否则重定向。
  5. 自定义获取设备码验证地址响应处理，前后端分离时直接返回前端的验证地址，否则重定向。
  6. 自定义校验设备码验证成功处理，在前后端分离时响应json，否则重定向。
  7. 授权接口中添加授权确认信息查询接口给分离前端的授权确认页面使用。
  8. 授权接口中添加设备码模式授权确认中转接口，如果是前后端分离则响应json，否则重定向。
  9. 在AuthorizationConfig中将自定义内容通过提供的配置入口添加配置。
  10. 开启两个过滤器链的CORS配置。
  11. 注入CorsConfigurationSource，实现跨域配置。
  12. 添加前端相关页面的实现。

编码

常量类在最后

1. 添加Spring Session Data Redis依赖。

<dependency><groupId>org.springframework.session</groupId><artifactId>spring-session-data-redis</artifactId>
</dependency>

2. 自定义登录成功、失败处理

在处理类内添加了前后端分离和不分离的适配，根据相关地址的配置自适应。

登录成功处理

在com.example.authorization.handler包下添加LoginSuccessHandler类。

java">package com.example.authorization.handler;import com.example.model.Result;
import com.example.util.JsonUtils;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;

import org.springframework.security.web.util.UrlUtils;import java.io.IOException;
import java.nio.charset.StandardCharsets;/*** 登录成功处理类** @author vains*/
@RequiredArgsConstructor
public class LoginSuccessHandler implements AuthenticationSuccessHandler {private final String loginPageUri;private final AuthenticationSuccessHandler authenticationSuccessHandler = new SavedRequestAwareAuthenticationSuccessHandler();@Override@SneakyThrowspublic void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException {// 如果是绝对路径(前后端分离)if (UrlUtils.isAbsoluteUrl(this.loginPageUri)) {Result<String> success = Result.success();response.setCharacterEncoding(StandardCharsets.UTF_8.name());response.setContentType(MediaType.APPLICATION_JSON_VALUE);response.getWriter().write(JsonUtils.objectCovertToJson(success));response.getWriter().flush();} else {authenticationSuccessHandler.onAuthenticationSuccess(request, response, authentication);}}}
登录失败处理

在com.example.authorization.handler包下添加LoginFailureHandler类。

java">package com.example.authorization.handler;import com.example.model.Result;
import com.example.util.JsonUtils;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;

import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.authentication.AuthenticationFailureHandler;
import org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler;
import org.springframework.security.web.util.UrlUtils;import java.io.IOException;
import java.nio.charset.StandardCharsets;/*** 登录失败处理类** @author vains*/
@Slf4j
public class LoginFailureHandler implements AuthenticationFailureHandler {private final String loginPageUri;private final AuthenticationFailureHandler authenticationFailureHandler;public LoginFailureHandler(String loginPageUri) {this.loginPageUri = loginPageUri;String loginFailureUrl = this.loginPageUri + "?error";this.authenticationFailureHandler = new SimpleUrlAuthenticationFailureHandler(loginFailureUrl);}@Override@SneakyThrowspublic void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException {log.debug("登录失败，原因：{}", exception.getMessage());// 如果是绝对路径(前后端分离)if (UrlUtils.isAbsoluteUrl(this.loginPageUri)) {log.debug("登录页面为独立的前端服务页面，写回json.");// 登录失败，写回401与具体的异常Result<String> success = Result.error(HttpStatus.UNAUTHORIZED.value(), exception.getMessage());response.setCharacterEncoding(StandardCharsets.UTF_8.name());response.setContentType(MediaType.APPLICATION_JSON_VALUE);response.getWriter().write(JsonUtils.objectCovertToJson(success));response.getWriter().flush();} else {log.debug("登录页面为认证服务的相对路径，跳转至：{}", this.loginPageUri);authenticationFailureHandler.onAuthenticationFailure(request, response, exception);}}}

3. 自定义重定向至登录页面处理

在重定向至登录页面时将当前请求的请求路径挂在登录页面的target参数中，前端登录成功后直接跳转至target中挂的url。

在com.example.authorization.handler包下添加LoginTargetAuthenticationEntryPoint类。

java">package com.example.authorization.handler;import com.example.model.Result;

import java.nio.charset.StandardCharsets;import static com.example.constant.SecurityConstants.DEVICE_ACTIVATE_URI;/*** 重定向至登录处理** @author vains*/
@Slf4j
public class LoginTargetAuthenticationEntryPoint extends LoginUrlAuthenticationEntryPoint {private final RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();/*** @param loginFormUrl URL where the login page can be found.

}

4. 自定义授权确认成功、失败处理

授权确认成功处理

在com.example.authorization.handler包下添加ConsentAuthorizationResponseHandler类。

java">package com.example.authorization.handler;import com.example.model.Result;

public class ConsentAuthorizationResponseHandler implements AuthenticationSuccessHandler {private final RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();@Overridepublic void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {// 获取将要重定向的回调地址String redirectUri = this.getAuthorizationResponseUri(authentication);if (request.getMethod().equals(HttpMethod.POST.name()) && UrlUtils.isAbsoluteUrl(CONSENT_PAGE_URI)) {// 如果是post请求并且CONSENT_PAGE_URI是完整的地址，则响应jsonResult<String> success = Result.success(redirectUri);response.setCharacterEncoding(StandardCharsets.UTF_8.name());response.setContentType(MediaType.APPLICATION_JSON_VALUE);response.getWriter().write(JsonUtils.objectCovertToJson(success));response.getWriter().flush();return;}// 否则重定向至回调地址this.redirectStrategy.sendRedirect(request, response, redirectUri);}/*** 获取重定向的回调地址** @param authentication 认证信息* @return 地址*/private String getAuthorizationResponseUri(Authentication authentication) {OAuth2AuthorizationCodeRequestAuthenticationToken authorizationCodeRequestAuthentication =(OAuth2AuthorizationCodeRequestAuthenticationToken) authentication;if (ObjectUtils.isEmpty(authorizationCodeRequestAuthentication.getRedirectUri())) {String authorizeUriError = "Redirect uri is not null";throw new OAuth2AuthorizationCodeRequestAuthenticationException(new OAuth2Error(INVALID_REQUEST, authorizeUriError, (null)), authorizationCodeRequestAuthentication);}if (authorizationCodeRequestAuthentication.getAuthorizationCode() == null) {String authorizeError = "AuthorizationCode is not null";throw new OAuth2AuthorizationCodeRequestAuthenticationException(new OAuth2Error(INVALID_REQUEST, authorizeError, (null)), authorizationCodeRequestAuthentication);}UriComponentsBuilder uriBuilder = UriComponentsBuilder.fromUriString(authorizationCodeRequestAuthentication.getRedirectUri()).queryParam(OAuth2ParameterNames.CODE, authorizationCodeRequestAuthentication.getAuthorizationCode().getTokenValue());if (StringUtils.hasText(authorizationCodeRequestAuthentication.getState())) {uriBuilder.queryParam(OAuth2ParameterNames.STATE,UriUtils.encode(authorizationCodeRequestAuthentication.getState(), StandardCharsets.UTF_8));}// build(true) -> Components are explicitly encodedreturn uriBuilder.build(true).toUriString();}}
授权确认失败处理

在com.example.authorization.handler包下添加ConsentAuthenticationFailureHandler类。

java">package com.example.authorization.handler;import com.example.model.Result;
import com.example.util.JsonUtils;
import jakarta.servlet.ServletException;
import jakarta.servlet.http.HttpServletRequest;

import java.nio.charset.StandardCharsets;import static com.example.constant.SecurityConstants.CONSENT_PAGE_URI;/*** 授权确认失败处理** @author vains*/
public class ConsentAuthenticationFailureHandler implements AuthenticationFailureHandler {@Overridepublic void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {// 获取当前认证信息Authentication authentication = SecurityContextHolder.getContext().getAuthentication();// 获取具体的异常OAuth2AuthenticationException authenticationException = (OAuth2AuthenticationException) exception;OAuth2Error error = authenticationException.getError();// 异常信息String message;if (authentication == null) {message = "登录已失效";} else {// 第二次点击“拒绝”会因为之前取消时删除授权申请记录而找不到对应的数据，导致抛出 [invalid_request] OAuth 2.0 Parameter: statemessage = error.toString();}// 授权确认页面提交的请求，因为授权申请与授权确认提交公用一个过滤器，这里判断一下if (request.getMethod().equals(HttpMethod.POST.name()) && UrlUtils.isAbsoluteUrl(CONSENT_PAGE_URI)) {// 写回json异常Result<Object> result = Result.error(HttpStatus.BAD_REQUEST.value(), message);response.setCharacterEncoding(StandardCharsets.UTF_8.name());response.setContentType(MediaType.APPLICATION_JSON_VALUE);response.getWriter().write(JsonUtils.objectCovertToJson(result));response.getWriter().flush();} else {// 在地址栏输入授权申请地址或设备码流程的验证地址错误(user_code错误)response.sendError(HttpStatus.BAD_REQUEST.value(), error.toString());}}}

5. 自定义获取设备码验证地址响应处理

在com.example.authorization.handler包下添加DeviceAuthorizationResponseHandler类。

java">package com.example.authorization.handler;import com.example.constant.SecurityConstants;
import jakarta.servlet.ServletException;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.server.ServletServerHttpResponse;
import org.springframework.security.core.Authentication;
import org.springframework.security.oauth2.core.OAuth2DeviceCode;
import org.springframework.security.oauth2.core.OAuth2UserCode;
import org.springframework.security.oauth2.core.endpoint.OAuth2DeviceAuthorizationResponse;
import org.springframework.security.oauth2.core.endpoint.OAuth2ParameterNames;

public class DeviceAuthorizationResponseHandler implements AuthenticationSuccessHandler {private final HttpMessageConverter<OAuth2DeviceAuthorizationResponse> deviceAuthorizationHttpResponseConverter =new OAuth2DeviceAuthorizationResponseHttpMessageConverter();@Overridepublic void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {OAuth2DeviceAuthorizationRequestAuthenticationToken deviceAuthorizationRequestAuthentication =(OAuth2DeviceAuthorizationRequestAuthenticationToken) authentication;OAuth2DeviceCode deviceCode = deviceAuthorizationRequestAuthentication.getDeviceCode();OAuth2UserCode userCode = deviceAuthorizationRequestAuthentication.getUserCode();// Generate the fully-qualified verification URIString issuerUri = AuthorizationServerContextHolder.getContext().getIssuer();UriComponentsBuilder uriComponentsBuilder;if (UrlUtils.isAbsoluteUrl(SecurityConstants.DEVICE_ACTIVATE_URI)) {uriComponentsBuilder = UriComponentsBuilder.fromHttpUrl(SecurityConstants.DEVICE_ACTIVATE_URI);} else {uriComponentsBuilder = UriComponentsBuilder.fromHttpUrl(issuerUri).path(SecurityConstants.DEVICE_ACTIVATE_URI);}String verificationUri = uriComponentsBuilder.build().toUriString();// 拼接user_codeString verificationUriComplete = uriComponentsBuilder.queryParam(OAuth2ParameterNames.USER_CODE, userCode.getTokenValue()).build().toUriString();OAuth2DeviceAuthorizationResponse deviceAuthorizationResponse =OAuth2DeviceAuthorizationResponse.with(deviceCode, userCode).verificationUri(verificationUri).verificationUriComplete(verificationUriComplete).build();ServletServerHttpResponse httpResponse = new ServletServerHttpResponse(response);this.deviceAuthorizationHttpResponseConverter.write(deviceAuthorizationResponse, null, httpResponse);}}

6. 自定义校验设备码验证成功处理

在com.example.authorization.handler包下添加DeviceVerificationResponseHandler类。

package com.example.authorization.handler;import com.example.model.Result;
import com.example.util.JsonUtils;
import jakarta.servlet.ServletException;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;
import org.springframework.http.MediaType;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.AuthenticationSuccessHandler;
import org.springframework.security.web.util.UrlUtils;import java.io.IOException;
import java.nio.charset.StandardCharsets;import static com.example.constant.SecurityConstants.DEVICE_ACTIVATED_URI;/*** 校验设备码成功响应类** @author vains*/
public class DeviceVerificationResponseHandler implements AuthenticationSuccessHandler {@Overridepublic void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {if (UrlUtils.isAbsoluteUrl(DEVICE_ACTIVATED_URI)) {// 写回json数据Result<Object> result = Result.success(DEVICE_ACTIVATED_URI);response.setCharacterEncoding(StandardCharsets.UTF_8.name());response.setContentType(MediaType.APPLICATION_JSON_VALUE);response.getWriter().write(JsonUtils.objectCovertToJson(result));response.getWriter().flush();} else {response.sendRedirect(DEVICE_ACTIVATED_URI);}}
}

7. 授权接口中添加授权确认信息查询接口给分离前端的授权确认页面使用

在AuthorizationController中添加并修改。

java">@GetMapping(value = "/oauth2/consent")
public String consent(Principal principal, Model model,@RequestParam(OAuth2ParameterNames.CLIENT_ID) String clientId,@RequestParam(OAuth2ParameterNames.SCOPE) String scope,@RequestParam(OAuth2ParameterNames.STATE) String state,@RequestParam(name = OAuth2ParameterNames.USER_CODE, required = false) String userCode) {// 获取consent页面所需的参数Map<String, Object> consentParameters = getConsentParameters(scope, state, clientId, userCode, principal);// 转至model中，让框架渲染页面consentParameters.forEach(model::addAttribute);return "consent";
}@ResponseBody
@GetMapping(value = "/oauth2/consent/parameters")
public Result<Map<String, Object>> consentParameters(Principal principal,@RequestParam(OAuth2ParameterNames.CLIENT_ID) String clientId,@RequestParam(OAuth2ParameterNames.SCOPE) String scope,@RequestParam(OAuth2ParameterNames.STATE) String state,@RequestParam(name = OAuth2ParameterNames.USER_CODE, required = false) String userCode) {// 获取consent页面所需的参数Map<String, Object> consentParameters = getConsentParameters(scope, state, clientId, userCode, principal);return Result.success(consentParameters);
}/*** 根据授权确认相关参数获取授权确认与未确认的scope相关参数** @param scope     scope权限* @param state     state* @param clientId  客户端id* @param userCode  设备码授权流程中的用户码* @param principal 当前认证信息* @return 页面所需数据*/
private Map<String, Object> getConsentParameters(String scope,String state,String clientId,String userCode,Principal principal) {// Remove scopes that were already approvedSet<String> scopesToApprove = new HashSet<>();Set<String> previouslyApprovedScopes = new HashSet<>();RegisteredClient registeredClient = this.registeredClientRepository.findByClientId(clientId);if (registeredClient == null) {throw new RuntimeException("客户端不存在");}OAuth2AuthorizationConsent currentAuthorizationConsent =this.authorizationConsentService.findById(registeredClient.getId(), principal.getName());Set<String> authorizedScopes;if (currentAuthorizationConsent != null) {authorizedScopes = currentAuthorizationConsent.getScopes();} else {authorizedScopes = Collections.emptySet();}for (String requestedScope : StringUtils.delimitedListToStringArray(scope, " ")) {if (OidcScopes.OPENID.equals(requestedScope)) {continue;}if (authorizedScopes.contains(requestedScope)) {previouslyApprovedScopes.add(requestedScope);} else {scopesToApprove.add(requestedScope);}}Map<String, Object> parameters = new HashMap<>(7);parameters.put("clientId", registeredClient.getClientId());parameters.put("clientName", registeredClient.getClientName());parameters.put("state", state);parameters.put("scopes", withDescription(scopesToApprove));parameters.put("previouslyApprovedScopes", withDescription(previouslyApprovedScopes));parameters.put("principalName", principal.getName());parameters.put("userCode", userCode);if (StringUtils.hasText(userCode)) {parameters.put("requestURI", "/oauth2/device_verification");} else {parameters.put("requestURI", "/oauth2/authorize");}return parameters;
}

8. 授权接口中添加设备码模式授权确认中转接口

在AuthorizationController中添加。

java">@SneakyThrows
@ResponseBody
@GetMapping(value = "/oauth2/consent/redirect")
public Result<String> consentRedirect(HttpSession session,HttpServletRequest request,HttpServletResponse response,@RequestParam(OAuth2ParameterNames.SCOPE) String scope,@RequestParam(OAuth2ParameterNames.STATE) String state,@RequestParam(OAuth2ParameterNames.CLIENT_ID) String clientId,@RequestParam(name = OAuth2ParameterNames.USER_CODE, required = false) String userCode) {// 携带当前请求参数与nonceId重定向至前端页面UriComponentsBuilder uriBuilder = UriComponentsBuilder.fromUriString(SecurityConstants.CONSENT_PAGE_URI).queryParam(OAuth2ParameterNames.SCOPE, UriUtils.encode(scope, StandardCharsets.UTF_8)).queryParam(OAuth2ParameterNames.STATE, UriUtils.encode(state, StandardCharsets.UTF_8)).queryParam(OAuth2ParameterNames.CLIENT_ID, clientId).queryParam(OAuth2ParameterNames.USER_CODE, userCode);String uriString = uriBuilder.build(Boolean.TRUE).toUriString();if (ObjectUtils.isEmpty(userCode) || !UrlUtils.isAbsoluteUrl(SecurityConstants.DEVICE_ACTIVATE_URI)) {// 不是设备码模式或者设备码验证页面不是前后端分离的，无需返回json，直接重定向this.redirectStrategy.sendRedirect(request, response, uriString);return null;}// 兼容设备码，需响应JSON，由前端进行跳转return Result.success(uriString);
}

9. 在AuthorizationConfig中将自定义内容通过提供的配置入口添加配置。

这一步基本就是组装了，将上边的自定义内容加入配置，使其生效。

完整的AuthorizationConfig配置在最后的附录中。

配置授权确认、获取设备码响应和设备码验证自定义处理，配置重定向至登录的自定义处理。
java">http.getConfigurer(OAuth2AuthorizationServerConfigurer.class)// 开启OpenID Connect 1.0协议相关端点.oidc(Customizer.withDefaults())// 设置自定义用户确认授权页.authorizationEndpoint(authorizationEndpoint ->authorizationEndpoint.consentPage(SecurityConstants.CONSENT_PAGE_URI).errorResponseHandler(new ConsentAuthenticationFailureHandler()).authorizationResponseHandler(new ConsentAuthorizationResponseHandler()))// 设置设备码用户验证url(自定义用户验证页).deviceAuthorizationEndpoint(deviceAuthorizationEndpoint ->deviceAuthorizationEndpoint.verificationUri(SecurityConstants.DEVICE_ACTIVATE_URI).deviceAuthorizationResponseHandler(new DeviceAuthorizationResponseHandler()))// 设置验证设备码用户确认页面.deviceVerificationEndpoint(deviceVerificationEndpoint ->// 设备码授权确认特殊处理，先重定向至后端服务，后端响应授权确认页面完整url给前端，前端跳转deviceVerificationEndpoint.consentPage(DEVICE_CONSENT_PAGE_URI).errorResponseHandler(new ConsentAuthenticationFailureHandler()).deviceVerificationResponseHandler(new DeviceVerificationResponseHandler()))
http// 当未登录时访问认证端点时重定向至login页面.exceptionHandling((exceptions) -> exceptions.defaultAuthenticationEntryPointFor(new LoginTargetAuthenticationEntryPoint(SecurityConstants.LOGIN_PAGE_URI),new MediaTypeRequestMatcher(MediaType.TEXT_HTML)));
oauth2consentparameters_708">在认证相关的过滤器链中添加登录响应处理，放行/oauth2/consent/parameters接口
java">/*** 配置认证相关的过滤器链** @param http spring security核心配置类* @return 过滤器链* @throws Exception 抛出*/
@Bean
public SecurityFilterChain defaultSecurityFilterChain(HttpSecurity http) throws Exception {// 开启CORS配置，配合下边的CorsConfigurationSource配置实现跨域配置http.cors(Customizer.withDefaults());// 禁用csrfhttp.csrf(AbstractHttpConfigurer::disable);http.authorizeHttpRequests((authorize) -> authorize// 放行静态资源.requestMatchers("/assets/**", "/webjars/**", "/login", "/getCaptcha", "/getSmsCaptcha", "/error", "/oauth2/consent/parameters").permitAll().anyRequest().authenticated())// 指定登录页面.formLogin(formLogin ->formLogin.loginProcessingUrl("/login")// 登录成功和失败改为写回json，不重定向了.successHandler(new LoginSuccessHandler()).failureHandler(new LoginFailureHandler(SecurityConstants.LOGIN_PAGE_URI)));// 在UsernamePasswordAuthenticationFilter拦截器之前添加验证码校验拦截器，并拦截POST的登录接口
//        http.addFilterBefore(new CaptchaAuthenticationFilter("/login"), UsernamePasswordAuthenticationFilter.class);// 添加BearerTokenAuthenticationFilter，将认证服务当做一个资源服务，解析请求头中的tokenhttp.oauth2ResourceServer((resourceServer) -> resourceServer.jwt(Customizer.withDefaults()).accessDeniedHandler(SecurityUtils::exceptionHandler).authenticationEntryPoint(SecurityUtils::exceptionHandler));http// 当未登录时访问认证端点时重定向至login页面.exceptionHandling((exceptions) -> exceptions.defaultAuthenticationEntryPointFor(new LoginTargetAuthenticationEntryPoint(SecurityConstants.LOGIN_PAGE_URI),new MediaTypeRequestMatcher(MediaType.TEXT_HTML)));return http.build();
}

10. 开启两个过滤器链的CORS配置。

在authorizationServerSecurityFilterChain和defaultSecurityFilterChain中添加以下配置。

java">// 开启CORS配置，配合下边的CorsConfigurationSource配置实现跨域配置
http.cors(Customizer.withDefaults());
// 禁用csrf
http.csrf(AbstractHttpConfigurer::disable);

11. 注入CorsConfigurationSource，实现跨域配置。

java">/*** 配置认证服务跨域过滤器** @return CorsConfigurationSource 实例*/
@Bean
public CorsConfigurationSource corsConfigurationSource() {UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();CorsConfiguration config = new CorsConfiguration();config.addAllowedHeader("*");config.addAllowedMethod("*");// 设置允许跨域的域名,如果允许携带cookie的话,路径就不能写*号, *表示所有的域名都可以跨域访问config.addAllowedOrigin("http://127.0.0.1:5173");// 设置跨域访问可以携带cookieconfig.setAllowCredentials(true);source.registerCorsConfiguration("/**", config);return source;
}

12. 添加前端相关页面的实现。

这里只放一下登录页面的代码，其它相关内容请前往代码仓库查看。

测试

测试时一定要注意，访问前端的ip与axios请求的ip保持一致！！！axios初始化时确保有withCredentials: true配置！！！
测试时一定要注意，访问前端的ip与axios请求的ip保持一致！！！axios初始化时确保有withCredentials: true配置！！！
测试时一定要注意，访问前端的ip与axios请求的ip保持一致！！！axios初始化时确保有withCredentials: true配置！！！
后端配置的前端相关地址的ip也要保持一致！！！
后端配置的前端相关地址的ip也要保持一致！！！
后端配置的前端相关地址的ip也要保持一致！！！
例如我下边的动图，访问前端的地址是127.0.0.1，那么axios请求后端的ip则应该都是127.0.0.1！

如果测试时想直接通过授权申请地址走流程那也应该要与上边的注意项保持一致，如果登录页面在后端配置的是127.0.0.1:5173/login，那么访问授权申请时就是127.0.0.1:8080/oauth2/authorize

  1. 访问授权申请
http://127.0.0.1:8080/oauth2/authorize?response_type=code&client_id=pkce-message-client&redirect_uri=http%3A%2F%2F127.0.0.1%3A5173%2FPkceRedirect&scope=message.read&code_challenge=kfis_wJYpmCAPO-Ap1Sc6GXyz_x2dhhMsm9FOA7eEWY&code_challenge_method=S256

登录

  1. 登录成功以后重定向回授权申请地址，授权申请端点生成授权码并重定向至回调地址

回调地址

到此为止，前后端分离已经基于Spring Session实现。
