整合spring cloud云架构 - SSO单点登录之OAuth2.0 根据token获取用户信息

Posted 2020-11-21 myfeiblogs

上一篇我根据框架中OAuth2.0的使用总结，画了SSO单点登录之OAuth2.0 登出流程，今天我们看一下根据用户token获取yoghurt信息的流程：

 

   /** 
 * 根据token获取用户信息 
 * @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);  
    }  
      
}  

 

我这里只是简单写了一些登出的代码，我们会在后面的文章中详细贴出所有代码供大家参考，而且会从创建数据库，到执行操作的每一个流程记录下来。
