Spring Security OAuth 个性化token

  个性化Token 目的
  
  默认通过调用 /oauth/token 返回的报文格式包含以下参数
  
  {
  
  "access_token": "e6669cdf-b6cd-43fe-af5c-f91a65041382",
  
  "token_type": "bearer",
  
  "refresh_token": "da91294d-446c-4a89-bdcf-88aee15a75e8",
  
  "expires_in": 43199,
  
  "scope": "server"
  
  }
  
  并没包含用户的业务信息比如用户信息、租户信息等。
  
  扩展生成包含业务信息(如下),避免系统多次调用,直接可以通过认证接口获取到用户信息等,大大提高系统性能
  
  {
  
  "access_token":"a6f3b6d6-93e6-4eb8-a97d-3ae72240a7b0",
  
  "token_type":"bearer",
  
  "refresh_token":"710ab162-a482-41cd-8bad-26456af38e4f",
  
  "expires_in":42396,
  
  "scope":"server",
  
  "tenant_id":1,
  
  "license":"made by pigx",
  
  "dept_id":1,
  
  "user_id":1,
  
  "username":"admin"
  
  }
  
  密码模式生成Token 源码解析

  ​ 主页参考红框部分
  
  ResourceOwnerPasswordTokenGranter (密码模式)根据用户的请求信息,进行认证得到当前用户上下文信息
  
  protected OAuth2Authentication getOAuth2Authentication(ClientDetails client, TokenRequest tokenRequest) {
  
  Map<String, String> parameters = new LinkedHashMap<String, String>(tokenRequest.getRequestParameters());
  
  String username = parameters.get("username");
  
  String password = parameters.get("password");
  
  // Protect from downstream leaks of password
  
  parameters.remove("password");
  
  Authentication userAuth = new UsernamePasswordAuthenticationToken(username, password);
  
  ((AbstractAuthenticationToken) userAuth).setDetails(parameters);
  
  userAuth = authenticationManager.authenticate(www.yinxionghui1.com/ userAuth);
  
  OAuth2Request storedOAuth2Request = getRequestFactory().createOAuth2Request(client, tokenRequest);
  
  return new OAuth2Authentication(storedOAuth2Request, userAuth);
  
  }
  
  然后调用AbstractTokenGranter.getAccessToken() 获取OAuth2AccessToken
  
  protected OAuth2AccessToken getAccessToken(ClientDetails client, TokenRequest tokenRequest) {
  
  return tokenServices.createAccessToken(getOAuth2Authentication(client, tokenRequest));
  
  }
  
  默认使用DefaultTokenServices来获取token
  
  public OAuth2AccessToken createAccessToken(OAuth2Authentication authentication) throws AuthenticationException {
  
  ... 一系列判断 ,合法性、是否过期等判断
  
  OAuth2AccessToken accessToken = createAccessToken(authentication, refreshToken);
  
  tokenStore.storeAccessToken(accessToken,www.dasheng178.com authentication);
  
  // In case it was modified
  
  refreshToken = accessToken.getRefreshToken();
  
  if (refreshToken != null) {
  
  tokenStore.storeRefreshToken(refreshToken, authentication);
  
  }
  
  return accessToken;
  
  }
  
  createAccessToken 核心逻辑
  
  // 默认刷新token 的有效期
  
  private int refreshTokenValiditySeconds = 60 * 60 * 24 * 30; // default 30 days.
  
  // 默认token 的有效期
  
  private int accessTokenValiditySeconds = 60 * 60 * 12; // default 12 hours.
  
  private OAuth2AccessToken createAccessToken(www.michenggw.com OAuth2Authentication authentication, OAuth2RefreshToken refreshToken) {
  
  DefaultOAuth2AccessToken token = new DefaultOAuth2AccessToken(uuid);
  
  token.setExpiration(Date)
  
  token.setRefreshToken(refreshToken);
  
  token.setScope(authentication.getOAuth2Request(www.tianshengyuLe1.cn).getScope());
  
  return accessTokenEnhancer != null ? accessTokenEnhancer.enhance(token, authentication) : token;
  
  }
  
  如上代码,在拼装好token对象后会调用认证服务器配置TokenEnhancer( 增强器) 来对默认的token进行增强。
  
  TokenEnhancer.enhance 通过上下文中的用户信息来个性化Token
  
  public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {
  
  final Map<String, Object> additionalInfo = new HashMap<www.zhongxinyul2.com>(8);
  
  PigxUser pigxUser =www.yongshi123.cn (PigxUser) authentication.getUserAuthentication().getPrincipal();
  
  additionalInfo.put("user_id", pigxUser.getId());
  
  additionalInfo.put("username", pigxUser.getUsername());
  
  additionalInfo.put("dept_id", pigxUser.getDeptId());
  
  additionalInfo.put("tenant_id", pigxUser.getTenantId());
  
  additionalInfo.put("license", SecurityConstants.PIGX_LICENSE);
  
  ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(additionalInfo);
  
  return accessToken;
  
  }
  
  基于pig 看下最终的实现效果
  
  Pig 基于Spring Cloud、oAuth2.0开发基于Vue前后分离的开发平台,支持账号、短信、SSO等多种登录,提供配套视频开发教程。
