|
||
* @description 样例接口的业务逻辑实现
|
||
*
|
||
* 设计思路：
|
||
* 1. 接收用户名参数，对参数进行基础校验
|
||
* 2. 使用Drizzle ORM查询数据库中的用户信息
|
||
* 3. 处理查询结果：用户存在则返回用户信息，不存在则抛出业务异常
|
||
* 4. 对敏感信息进行过滤，不返回密码哈希等敏感字段
|
||
* 5. 统一异常处理，确保返回标准的错误响应格式
|
||
* 6. 记录操作日志，便于系统监控和问题排查
|
||
*
|
||
* 安全考虑：
|
||
* - 严格过滤敏感信息，不向客户端返回密码哈希
|
||
* - 对查询参数进行SQL注入防护（Drizzle ORM自带防护）
|
||
* - 记录查询日志，便于安全审计
