Spring Cloud雲架構 - SSO單點登陸之OAuth2.0 根據token獲取用戶信息(4)

上一篇我根據框架中OAuth2.0的使用總結，畫了SSO單點登陸之OAuth2.0 登出流程，今天咱們看一下根據用戶token獲取yoghurt信息的流程：

 

      /**
 * 根據token獲取用戶信息
 * @param accessToken
 * @return
 * @throws Exception
 */
@RequestMapping(value = "/user/token/{accesstoken}", method = RequestMethod.GET)
public ResponseVO getUserByToken(@PathVariable(value = "accessToken", required = true) String accessToken,@RequestHeader(value = "userId", required = true) Long userId) throws Exception {
    if(StringUtils.isEmpty(accessToken)){
        return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_REQ_CANNOT_EMPTY, null);
    }

    OauthAccessToken oauthAccessToken = userMgrService.getOauthAccessToken(accessToken);
    if(null == oauthAccessToken){
        return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_OAUTH_ACCESSTOKEN_EMPTY, null);
    }

    String userName = oauthAccessToken.getUserName();
    if (StringUtils.isEmpty(userName)) {
        return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_OAUTH_ACCESSTOKEN_EMPTY, null);
    }

    return this.getUser(userName);
}

       @RequestMapping(path = "/user/get/{userName}", method = RequestMethod.GET)
public ResponseVO getUser(@PathVariable(value = "userName") String userName) {
    Map<String, Object> returnData = null;
    try {
        User user = userMgrService.getUserByName(userName);
        if (null != user) {
            returnData = new HashMap<String, Object>();
            returnData.put("user", user);
            return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_SUCCESS, returnData);
        }
        return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_SYSTEM_ERROR, null);
    } catch (Exception e) {
        return UserResponseCode.buildEnumResponseVO(UserResponseCode.RESPONSE_CODE_SYSTEM_ERROR, null);
    }

}

 

我這裏只是簡單寫了一些登出的代碼，咱們會在後面的文章中詳細貼出全部代碼供你們參考，並且會從建立數據庫，到執行操做的每個流程記錄下來。

 

從如今開始，我這邊會將近期研發的spring cloud微服務雲架構的搭建過程和精髓記錄下來，幫助更多有興趣研發spring cloud框架的朋友，你們來一塊兒探討spring cloud架構的搭建過程及如何運用於企業項目。源碼來源
