個性化Token 目的
默認通過調用 /oauth/token 返回的報文格式包含以下參數
{ "access_token": "e6669cdf-b6cd-43fe-af5c-f91a65041382", "token_type": "bearer", "refresh_token": "da91294d-446c-4a89-bdcf-88aee15a75e8", "expires_in": 43199, "scope": "server" }
并沒包含用戶的業務信息比如用戶信息、租戶信息等。
擴展生成包含業務信息(如下),避免系統多次調用,直接可以通過認證接口獲取到用戶信息等,大大提高系統性能
{ "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" }
密碼模式生成Token 源碼解析
主頁參考紅框部分
ResourceOwnerPasswordTokenGranter (密碼模式)根據用戶的請求信息,進行認證得到當前用戶上下文信息
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); }
然后調用AbstractTokenGranter.getAccessToken() 獲取OAuth3AccessToken
protected OAuth3AccessToken getAccessToken(ClientDetails client, TokenRequest tokenRequest) { return tokenServices.createAccessToken(getOAuth3Authentication(client, tokenRequest)); }
默認使用DefaultTokenServices來獲取token
public OAuth3AccessToken createAccessToken(OAuth3Authentication authentication) throws AuthenticationException { ... 一系列判斷 ,合法性、是否過期等判斷 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 核心邏輯
// 默認刷新token 的有效期 private int refreshTokenValiditySeconds = 60 * 60 * 24 * 30; // default 30 days. // 默認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; }
如上代碼,在拼裝好token對象后會調用認證服務器配置TokenEnhancer( 增強器) 來對默認的token進行增強。
TokenEnhancer.enhance 通過上下文中的用戶信息來個性化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 看下最終的實現效果
Pig 基于Spring Cloud、oAuth3.0開發基于Vue前后分離的開發平臺,支持賬號、短信、SSO等多種登錄,提供配套視頻開發教程。
