🎯 修复步骤：

1. 问题诊断：
   ❌ 后端 /tgAccount/list 路由返回 404
   ✅ 数据库有 2909 条 TG 账号数据
   ❌ 前端无法获取数据显示"暂无数据"

2. 立即修复方案：
   📡 启动临时API服务（推荐）：
   cd /Users/hahaha/telegram-management-system
   npm install mysql2 express cors
   node temp-api-server.js

3. 前端配置修改：
   📝 修改前端API基础URL指向临时服务
   🔄 重新测试页面数据加载

4. 长期修复方案：
   🔧 修复后端路由配置问题
   🧪 确保路由正确注册和认证
   📊 完善数据返回格式

📊 数据验证：
   • MySQL表: accounts (2909条记录)
   • 状态分布: 全部为活跃状态
   • 临时API将提供正确的数据格式

🚀 现在执行临时修复方案！
