构建安全护盾：HarmonyOS 应用的数据安全审计与日志管理实战

// LogManager.ts - 日志管理模块
export class LogManager {
    static log(action: string, details: any): void {
        const logEntry = {
            timestamp: new Date().toISOString(),
            action,
            details
        };
        console.info(`[AUDIT LOG]: ${JSON.stringify(logEntry)}`);
        // 可将日志保存到本地文件或远程服务器
    }
}

import { LogManager } from './LogManager';

// 用户登录事件
function userLogin(username: string): void {
    // 模拟登录逻辑
    const success = Math.random() > 0.5;

    // 审计日志记录
    LogManager.log("User Login", {
        username,
        success,
        timestamp: new Date().toISOString()
    });

    if (success) {
        console.info("Login successful");
    } else {
        console.warn("Login failed");
    }
}

// RealTimeLogger.ts - 实时日志管理模块
export class RealTimeLogger {
    private logs: Array<any> = [];

    log(level: string, message: string): void {

const logger = new RealTimeLogger();

// 记录日志
logger.log("INFO", "Application started");

// 查询日志

// 清理日志
