Spring Security OAuth 个性化token的使用

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

Spring Security OAuth 个性化token的使用

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 OAuth3Authentication getOAuth3Authentication(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(userAuth);

 OAuth3Request storedOAuth3Request = getRequestFactory().createOAuth3Request(client, tokenRequest);  
  return new OAuth3Authentication(storedOAuth3Request, userAuth);
}

然后调用AbstractTokenGranter.getAccessToken() 获取OAuth3AccessToken

protected OAuth3AccessToken getAccessToken(ClientDetails client, TokenRequest tokenRequest) {
 return tokenServices.createAccessToken(getOAuth3Authentication(client, tokenRequest));
}

默认使用DefaultTokenServices来获取token

public OAuth3AccessToken createAccessToken(OAuth3Authentication authentication) throws AuthenticationException {

 ... 一系列判断 ，合法性、是否过期等判断 
 OAuth3AccessToken accessToken = createAccessToken(authentication, refreshToken);
  tokenStore.storeAccessToken(accessToken, 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 OAuth3AccessToken createAccessToken(OAuth3Authentication authentication, OAuth3RefreshToken refreshToken) {
 DefaultOAuth3AccessToken token = new DefaultOAuth3AccessToken(uuid);
 token.setExpiration(Date)
 token.setRefreshToken(refreshToken);
 token.setScope(authentication.getOAuth3Request().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 OAuth3AccessToken enhance(OAuth3AccessToken accessToken, OAuth3Authentication authentication) {
 final Map<String, Object> additionalInfo = new HashMap<>(8);
 PigxUser pigxUser = (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);
 ((DefaultOAuth3AccessToken) accessToken).setAdditionalInformation(additionalInfo);
 return accessToken;
}

基于pig 看下最终的实现效果

Pig 基于Spring Cloud、oAuth3.0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。
