# 实时消息推送系统使用指南
## 🆕 最新更新 (v2.10.0 - 点击加载反馈)
## 🆕 最新更新 (v2.11.0 - Socket 连接优化)
### 优化内容
#### 1. **指数退避策略** 🔄
-**智能重连间隔**:从"激进"改为"渐进"策略
- Real Socket: 第1次 1分钟 → 第2次 2分钟 → 第3次+ 4分钟
- Mock Socket: 第1次 10秒 → 第2次 20秒 → 第3次+ 40秒缩短10倍便于测试
-**无限重试**不再在5次后停止持续使用指数退避重连
-**自定义退避逻辑**:禁用 Socket.IO 默认重连机制,实现更可控的重连策略
#### 2. **连接状态横幅优化** 📍
-**降低侵入性**zIndex 从 10000 → 1050高度 py={3} → py={2}半透明背景opacity 0.95
-**手动关闭**所有状态DISCONNECTED/RECONNECTING/FAILED都可手动关闭
-**状态持久化**:用户关闭后保存到 localStorage重连成功后自动清除
-**自动消失**:重连成功显示"✓ 已重新连接" 2秒后自动消失
-**无限次数显示**:支持 Infinity 最大重连次数,显示"尝试重连中 (第 N 次)"
#### 3. **Mock 模式测试功能** 🧪
-**断线重连模拟**`__mockSocket.simulateDisconnection()` - 模拟意外断线,自动重连
-**连接状态查询**`__mockSocket.isConnected()` - 查看当前连接状态
-**手动重连**`__mockSocket.reconnect()` - 立即触发重连
-**重连次数查询**`__mockSocket.getAttempts()` - 查看当前重连次数
-**控制台提示**:开发模式启动时自动显示可用测试函数
#### 4. **环境说明** 🌍
-**清晰注释**:在 NotificationContext.js 添加详细的环境说明
- `SOCKET_TYPE === 'REAL'`:使用真实 Socket.IO连接 wss://valuefrontier.cn生产环境
- `SOCKET_TYPE === 'MOCK'`:使用模拟服务(开发环境),用于本地测试
-**环境切换**:设置 `REACT_APP_ENABLE_MOCK=true``REACT_APP_USE_MOCK_SOCKET=true` 切换到 MOCK 模式
### 测试方法
#### Mock 模式下测试断线重连:
1. **启用 Mock 模式**
```bash
# .env 文件
REACT_APP_ENABLE_MOCK=true
```
2. **场景1模拟断线自动重连成功**
打开控制台,运行以下命令:
```javascript
// 查看可用测试函数
console.log(window.__mockSocket);
// 模拟断线(自动重连)
__mockSocket.simulateDisconnection();
// 观察重连过程:
// - 连接状态横幅会出现("正在重新连接"
// - 重连次数递增第1次 10s → 第2次 20s → 第3次 40s
// - 重连成功后显示"✓ 已重新连接" 2秒后自动消失
// 查看连接状态
__mockSocket.isConnected(); // true/false
// 查看重连次数
__mockSocket.getAttempts(); // 0, 1, 2, 3...
// 手动重连(立即重置重连次数)
__mockSocket.reconnect();
```
3. **场景2模拟持续连接失败** 🆕
打开控制台,运行以下命令:
```javascript
// 模拟持续连接失败
__mockSocket.simulateConnectionFailure();
// 观察效果:
// - 连接状态横幅出现:"正在重新连接 (第 1 次)"
// - 10秒后"正在重新连接 (第 2 次)"
// - 20秒后"正在重新连接 (第 3 次)"
// - 40秒后"正在重新连接 (第 4 次)"
// - 继续以 40秒间隔重试... (第 5/6/7... 次)
// 测试手动关闭横幅
// 点击横幅右侧的 ✕ 按钮 → 横幅消失
// 查看重连次数(后台仍在重连)
__mockSocket.getAttempts(); // 递增中...
// 允许下次重连成功
__mockSocket.allowReconnection();
// 观察效果:
// - 如果横幅已关闭:下次重连成功时会重新出现 "✓ 已重新连接"2秒后消失
// - 如果横幅未关闭:直接显示 "✓ 已重新连接"2秒后消失
// 也可以手动立即重连
__mockSocket.reconnect(); // 立即成功(如果已调用 allowReconnection
```
4. **测试手动关闭**
- 模拟断线后,点击状态横幅右侧的 ✕ 按钮
- 横幅消失,保存到 localStorage
- 重连成功后,横幅会重新出现 2秒"✓ 已重新连接")然后自动消失
### 测试函数速查表
| 函数 | 说明 | 使用场景 |
|------|------|----------|
| `__mockSocket.simulateDisconnection()` | 模拟断线,自动重连成功 | 测试正常重连流程 |
| `__mockSocket.simulateConnectionFailure()` | 模拟持续连接失败 | 测试重连失败、指数退避 |
| `__mockSocket.allowReconnection()` | 允许下次重连成功 | 配合 `simulateConnectionFailure()` 使用 |
| `__mockSocket.isConnected()` | 查看当前连接状态 | 调试连接状态 |
| `__mockSocket.reconnect()` | 手动立即重连 | 测试"立即重试"按钮 |
| `__mockSocket.getAttempts()` | 查看当前重连次数 | 验证指数退避逻辑 |
### 技术细节
- **文件修改**
- `src/services/socketService.js` - 指数退避逻辑,无限重试
- `src/services/mockSocketService.js` - 模拟断线重连,测试函数
- `src/components/ConnectionStatusBar/index.js` - UI 优化,手动关闭
- `src/App.js` - dismissed 状态管理localStorage 持久化
- `src/contexts/NotificationContext.js` - 重连成功检测maxReconnectAttempts 导出
