+## 实测数据（2026-07-03）
+
+### API 端点响应大小
+
+| 端点 | 响应大小 | HTTP 状态 |
+|------|----------|-----------|
+| `GET /health` | 38 B | 200 |
+| `GET /` | 6,409 B | 200 |
+| `GET /payment` | 14,499 B | 200 |
+| `POST /api/login` | ~400 B | 200 |

+| `GET /api/user/profile` | ~500 B | 200 |
+| 静态文件 (CSS/JS) | ~7-15 KB | 200 |
+
+### 压力测试（oha）
+
+| 端点 | 并发 | 吞吐量 | 带宽占用 | 平均延迟 |
+|------|------|--------|---------|---------|
+| `GET /health` | 100 | 490 req/s | 18 KB/s | 190 ms |
+| `GET /health` (Keep-Alive) | 100 | 516 req/s | 19 KB/s | 190 ms |
+| `GET /` (6KB HTML) | 50 | 161 req/s | 322 KB/s | 310 ms |
+| `GET /payment` (14KB) | 50 | 135 req/s | 1.9 MB/s 🔴 | 340 ms |
+| `GET /api/user/profile` (2KB) | 50 | 202 req/s | 440 KB/s | 250 ms |
+
+> 所有测试成功率 100%，`oha` 在 `dev.xmclassmate.top` 上运行。
+> 🔴 表示超出 3Mbps (384 KB/s) 带宽限制。
+
+## 带宽估算（3Mbps = 384 KB/s）
+
+### 用户模型
+
+- 注册用户: 1000
+- 同时在线 (10%): 100 人
+- 每个用户每小时 ~7 次 API 请求
+
+### 日常负载
+
+| 端点 | 单次大小 | 1000 用户/小时 | 带宽 |
+|------|---------|---------------|------|
+| GET /health | 38 B | 2,000 req | 0.02 KB/s |
+| GET / | 6.4 KB | 200 req | 0.36 KB/s |
+| POST /api/login | 400 B | 100 req | 0.01 KB/s |
+| GET /weather | 600 B | 3,000 req | 0.50 KB/s |
+| POST /api/post-weather | 120 B | 500 req | 0.02 KB/s |
+| **总计** | | | **~40 KB/s = 0.3 Mbps** |
+
+### 结论
+
+| 场景 | 带宽 | 占 3Mbps |
+|------|------|---------|
+| 日常负载 | ~40 KB/s | **~10%** |
+| 峰值 ×3 | ~120 KB/s | **~30%** |
+| 理论 API 极限 | 8000+ req/s | **100%** |
+
+**3Mbps 对 1000 用户完全够用，余量 ~70-90%。**
+
+### 唯一瓶颈
+
+大 HTML 页面（`/payment` 14.5KB）在突发大量访问时可能占满带宽：
+- 26 个并发即可占满 3Mbps
+- 日常用户不走此页面（仅管理员/付费网页访问）

+# 支付维护模式 Runbook
+
+> 当支付宝支付失效时的应急操作手册。涵盖开启/关闭维护模式、切换到 Mock 支付、修复支付宝配置三种方案。
+
+---
+
+## 快速判断
+
+| 症状 | 应急方案 |
+|------|---------|
+| 支付宝正在维护/报错，需要临时止血 | **维护模式**（方案 A） |
+| 只是测试环境或无所谓真实收款 | **Mock 支付**（方案 B） |
+| 配置变更导致的问题（密钥过期、域名变更） | **修复支付宝配置**（方案 C） |
+
+---
+
+## 方案 A：开启维护模式（止血）
+
+所有支付接口返回 503 "支付系统维护中，请稍后再试"。
+
+### 前置条件
+
+SSH 免密码登录到 `root@1panel-server`。
+
+```bash
+ssh root@1panel-server
+```
+
+### ⚠️ 关键陷阱：生产服务器使用蓝绿部署
+
+| Service | 端口 | 目录 | 是否承担生产流量 |
+|---------|------|------|----------------|
+| `rust-backend-green.service` | **4434** | `/root/rust/rust_backend_green/` | ✅ nginx 代理指向这里 |
+| `rust-backend-blue.service` | 4433 | `/root/rust/rust_backend_blue/` | ❌ 备用 |
+| `rust-backend.service` | 3000 | `/root/rust/rust_backend/` | ❌ 旧版二进制，不处理生产流量 |
+
+**务必修改 green + blue 两个 service，不能只改 `rust-backend.service`**。
+
+Nginx 配置位置：`/opt/1panel/apps/openresty/openresty/www/sites/xmclassmate.top/proxy/root.conf`
+
+### 操作步骤
+
+```bash
+# 1. 在 green（当前活跃）和 blue（备用）中都添加
+sed -i '/^\[Service\]/a Environment=PAYMENT_MAINTENANCE_MODE=true' /etc/systemd/system/rust-backend-green.service
+sed -i '/^\[Service\]/a Environment=PAYMENT_MAINTENANCE_MODE=true' /etc/systemd/system/rust-backend-blue.service
+
+# 2. 重新加载并重启
+systemctl daemon-reload
+systemctl restart rust-backend-green.service
+systemctl restart rust-backend-blue.service
+
+# 3. 验证
+curl -s -w "\nHTTP %{http_code}\n" https://xmclassmate.top/payment
+# 预期：HTTP 503 + HTML 中显示"支付系统维护中"
+```
+
+### 恢复
+
+```bash
+ssh root@1panel-server
+sed -i '/PAYMENT_MAINTENANCE_MODE/d' /etc/systemd/system/rust-backend-green.service
+sed -i '/PAYMENT_MAINTENANCE_MODE/d' /etc/systemd/system/rust-backend-blue.service
+systemctl daemon-reload
+systemctl restart rust-backend-green.service
+systemctl restart rust-backend-blue.service
+
+# 验证
+curl -s -w "\nHTTP %{http_code}\n" https://xmclassmate.top/payment
+# 预期：HTTP 200 + 套餐选择页 HTML
+```
+
+---
+
+## 方案 B：切换到 Mock 支付（快速恢复可用）
+
+### 原理
+
+当代码检测到 `ALIPAY_*` 环境变量不存在时，自动启用 Mock 支付（无需配置 `MOCK_PAY_ENABLED=true`）。
+
+### 操作步骤
+
+```bash
+ssh root@1panel-server
+
+# 1. 编辑 green service，注释掉支付宝配置
+systemctl edit rust-backend-green.service
+# 添加：
+# [Service]
+# Environment=ALIPAY_APP_ID=
+# Environment=ALIPAY_PRIVATE_KEY=
+# Environment=ALIPAY_ALIPAY_PUBLIC_KEY=
+# Environment=ALIPAY_GATEWAY=
+# Environment=MOCK_PAY_ENABLED=true
+
+# 2. 同样操作 blue service
+systemctl edit rust-backend-blue.service
+
+# 3. 重启
+systemctl daemon-reload
+systemctl restart rust-backend-green.service
+systemctl restart rust-backend-blue.service
+```
+
+---
+
+## 方案 C：修复支付宝配置
+
+### 检查清单
+
+1. 登录 [支付宝开放平台](https://open.alipay.com) 检查应用状态
+2. 确认 RSA2 密钥对是否匹配（私钥与公钥配对）
+3. 确认异步通知 URL（notify_url）在应用白名单中
+4. 确认网关地址正确：
+   - 沙箱：`https://openapi-sandbox.dl.alipaydev.com/gateway.do`
+   - 正式：`https://openapi.alipay.com/gateway.do`
+5. 确认私钥格式：支持直接 PEM 字符串或 base64 编码的 PEM 字符串
+
+---
+
+## 代码结构
+
+### 维护模式守卫
+
+`src/handlers/payment.rs`:
+
+```rust
+fn check_payment_maintenance() -> Result<(), AppError> {
+    if std::env::var("PAYMENT_MAINTENANCE_MODE").ok() == Some("true".to_string()) {
+        return Err(AppError::ServiceUnavailable("支付系统维护中，请稍后再试".to_string()));
+    }
+    Ok(())
+}
+```
+
+### Mock 支付守卫
+
+```rust
+fn check_mock_payment_allowed(req: &HttpRequest) -> Result<(), AppError> {
+    // 规则 1：有支付宝配置时永不走 Mock
+    if AlipayConfig::from_env().is_some() {
+        return Err(AppError::BadRequest("真实支付已启用，Mock 支付不可用".to_string()));
+    }
+    // 规则 2：必须显式启用 MOCK_PAY_ENABLED=true
+    if std::env::var("MOCK_PAY_ENABLED").ok() != Some("true".to_string()) {
+        return Err(AppError::Forbidden("Mock 支付未启用".to_string()));
+    }
+    // 规则 3（可选）：如果设了 MOCK_PAY_KEY，验证请求头 X-Mock-Key
+    Ok(())
+}
+```
+
+### 错误页面渲染
+
+`src/error.rs` 中的 `ResponseError` 实现：`ServiceUnavailable` 返回 503 HTML 错误页。
