标题

这是第一段内容。

这是第二段内容。

在HarmonyOS Next中封装LOG日志可从以下方向入手：

  1. 使用系统提供的HiLog模块，这是鸿蒙原生日志系统，支持级别过滤和标签分类

  2. 考虑日志持久化，使用分布式文件系统接口实现本地存储

  3. 对接鸿蒙的分布式能力，实现跨设备日志收集

  4. 封装日志级别控制（DEBUG/INFO/WARN/ERROR）

  5. 添加时间戳和设备信息等元数据

  6. 注意使用鸿蒙的权限机制管理日志文件访问

在HarmonyOS Next中封装LOG日志模块，建议从以下几个核心方向入手：

  1. 日志分级设计
  • 实现DEBUG/INFO/WARN/ERROR等级别
  • 可动态调整输出级别（如release模式自动关闭DEBUG）
  • 使用@LogLevel注解标记关键日志
  1. 多输出渠道
  • 控制台输出（开发阶段）
  • 文件存储（使用HiLog或自定义文件写入）
  • 可选网络上报（通过@Ability接口）
  1. 性能优化要点
  • 采用异步写入机制
  • 实现日志缓存队列
  • 限制单条日志长度（建议<4KB）
  1. 安全处理
  • 敏感信息自动脱敏（如手机号、token等）
  • 日志文件加密存储
  • 访问权限控制（使用ohos.security权限管理）
  1. 实用功能扩展
  • 添加线程/时间戳标记
  • 支持崩溃日志自动捕获
  • 实现日志文件轮转(按大小/时间)

示例代码结构建议：

public class AppLogger {
    // 初始化配置
    public static init(config: LogConfig) {}
    
    // 分级日志方法
    public static debug(tag: string, msg: string) {}
    public static error(tag: string, msg: string) {}
    
    // 日志上报
    public static upload() {}
}

注意利用HarmonyOS的HiLog基础能力（ohos.hilog）作为底层实现，可保证系统兼容性。关键业务流程建议添加@Track注解实现自动埋点。
