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

  • 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 parameters = new LinkedHashMap(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);
    
        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, 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(OAuth2Authentication authentication, OAuth2RefreshToken refreshToken) {
        DefaultOAuth2AccessToken token = new DefaultOAuth2AccessToken(uuid);
        token.setExpiration(Date)
        token.setRefreshToken(refreshToken);
        token.setScope(authentication.getOAuth2Request().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 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);
        ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(additionalInfo);
        return accessToken;
    }
