-    - 单元测试：工具函数、数据结构

-    - 集成测试：API 端点
+    - `src/rate_limiter.rs`：限流阈值、按客户端隔离、IP 提取（已有）

 # 服务器邮件告警与每日报告 — 部署指南
 <!-- 更新时间：2026-08-21 -->
 ## 概述
 两封自动邮件，均通过 `msmtp` → 163 SMTP 发送（复用现有 `~/.msmtprc` 配置）：
 | 脚本 | 频率（cron） | 作用 |
 | --- | --- | --- |
 | `daily-report.sh` | 每日 08:00 | 服务器健康报告（HTML）：系统/容器/SSL/服务/安全/备份 + **支付与会员统计** |
 | `alert.sh` | 每 5 分钟 | **实时异常告警**：正常时静默，异常才发邮件（带防刷屏状态机） |
 ## 部署步骤
 ```bash
 # 1. 上传三个文件到服务器（root 用户）
 scp scripts/mail-lib.sh scripts/daily-report.sh scripts/alert.sh root@<服务器>:/root/rust/scripts/
 ssh root@<服务器> 'chmod +x /root/rust/scripts/*.sh && mkdir -p /root/rust/scripts/logs'
 # 2. 配置 cron（root）
 ssh root@<服务器> 'crontab -e'
 # 加入以下两行：
 0 8 * * * /root/rust/scripts/daily-report.sh >> /root/rust/scripts/logs/daily-report.log 2>&1
 */5 * * * * /root/rust/scripts/alert.sh >> /root/rust/scripts/logs/alert.log 2>&1
 ```
 ## 验证
 ```bash
 # 干跑告警（预览当前异常与将发送的邮件，不真正发送）
 /root/rust/scripts/alert.sh --dry-run
 # 手动发一封健康报告测试 msmtp 链路
 /root/rust/scripts/daily-report.sh
 # 查看邮件日志
 tail -50 /root/rust/scripts/logs/mail.log
 ```
 ## alert.sh 检测项与阈值
 | 检测项 | 警告 | 严重 |
 | --- | --- | --- |
 | 磁盘使用（/） | > 80% | > 90% |
 | 内存使用 | > 80% | > 90% |
 | 备份时效 | > 24h | > 48h（或无备份） |
 | 服务状态（green/blue/nginx） | — | 非 active |
 | Docker 容器 | — | 存在非 Up 容器 / docker 不可用 |
 | SSL 证书剩余 | < 30 天 | < 7 天 |
 | 支付卡单（pending > 30 分钟） | ≥ 1 笔（附订单号） | — |
 | 数据库（SELECT 1） | — | 不可用 |
 ### 防刷屏机制
 状态文件 `.alert-state`（默认 `/root/rust/scripts/.alert-state`）记录每个检测项最近告警级别：
 - 级别**上升** → 立即发邮件
 - 级别**不变** → 冷却 `ALERT_COOLDOWN_HOURS`（默认 6 小时）后才再次提醒
 - **恢复**正常 → 静默清除状态，不发邮件
 ## 可配置项（环境变量）
 | 变量 | 默认值 | 说明 |
 | --- | --- | --- |
 | `MAIL_TO` | `m943790568@163.com` | 收件人，逗号分隔多地址 |
 | `MAIL_FROM` | `ASD 监控 <m943790568@163.com>` | 发件人显示名 |
 | `MAIL_ACCOUNT` | `default` | msmtp 账户名 |
 | `MAIL_LOG_DIR` | `/root/rust/scripts/logs` | 日志目录（mail.log / alert.log） |
 | `MAIL_RETRY` | `3` | 发送失败重试次数 |
 | `DB_CONTAINER` | `1Panel-postgresql-FtMo` | PostgreSQL 容器名（1Panel 安装） |
 | `BACKUP_DIR` | `/root/rust/backups/milkydata` | 备份目录 |
 | `STUCK_ORDER_MINUTES` | `30` | pending 订单视为卡单的时长 |
 | `ALERT_STATE_FILE` | `/root/rust/scripts/.alert-state` | 状态文件路径 |
 | `ALERT_COOLDOWN_HOURS` | `6` | 同级别再次提醒的冷却时间 |
 ## 注意事项
 - 脚本在**服务器本机**运行（cron 以 root 执行），数据库通过 `docker exec <容器> psql` 访问，
  容器名与 `check-members.sh` / `send-notification.sh` 保持一致；如容器名不同，设置 `DB_CONTAINER` 覆盖。
 - 邮件为 HTML + UTF-8，无需额外编码配置；msmtp 发送失败自动重试 3 次并记录日志。
 - 单次采集失败（如 journalctl 无权限）不会阻断整封邮件，对应项显示 N/A。
 - `alert.sh` 的卡单检测可直接发现「支付卡在确认页面」类问题（pending 超 30 分钟即告警，
  邮件中附订单号与创建时间，便于对照支付宝账单处理）。

  -v /www/sites:/www/sites \
  1panel/openresty:1.21.4.3-3-3-focal

 ```
 ## 阶段 2 — 后端部署
 ### 2.1 创建 systemd 服务（blue/green/dev）
 ```bash
 # 创建目录
 mkdir -p /root/rust/rust_backend_blue
 mkdir -p /root/rust/rust_backend_green
 mkdir -p /root/rust/rust_backend_dev
 # 注册 systemd service（从 deploy/ 目录上传）
 ```
 ### 2.2 部署 Rust 后端
 ```bash
 # 先部署到 dev 验证
 cd ASD-backend/rust-backend
-deploy.sh development --remote-host 47.109.203.92
+deploy.sh development --remote-host xxx.xxx.xxx.xxx
-
+deploy.sh production --remote-host xxx.xxx.xxx.xxx
 # 再部署 blue/green
 deploy.sh production --remote-host 47.109.203.92
 ```
 ### 2.3 更新 deploy.sh
-将默认 REMOTE_HOST 改为新服务器 IP
+将默认 REMOTE_HOST 改为新服务器 IP。
-## 阶段 3 — 切换
+## 阶段 3 — ⚠️ 关键配置（迁移后必做）
 ### 3.1 设置 APP_BASE_URL
 每个环境的 `.env` 文件必须设置 `APP_BASE_URL`，否则默认值为 `https://dev.xmclassmate.top`，导致支付宝通知回调发错服务器。
 ### 3.1 内部验证
 ```bash
-curl http://127.0.0.1:8080/health  # dev
+# 生产环境
-curl -k https://127.0.0.1:4433/health  # blue
+echo "APP_BASE_URL=https://xmclassmate.top" >> /root/rust/rust_backend_blue/.env
-curl -k https://127.0.0.1:4434/health  # green
+echo "APP_BASE_URL=https://xmclassmate.top" >> /root/rust/rust_backend_green/.env
 # 开发环境
 echo "APP_BASE_URL=https://dev.xmclassmate.top" >> /root/rust/rust_backend_dev/.env
 ```
-### 3.2 更新 DNS
+### 3.2 验证 notify_url
 将域名指向新服务器 IP
-### 3.3 验证公网访问
+迁移后通过 API 检查支付表单的 notify_url 是否正确：
 ```bash
 # 获取访客 JWT
 JWT=$(curl -s -X POST 'https://YOUR_DOMAIN/api/guest-login' | python3 -c "import sys,json; print(json.load(sys.stdin)['token'])")
 # 检查支付表单的 notify_url
 curl -s "https://YOUR_DOMAIN/payment/page?package=monthly&jwt=${JWT}" | grep -oP 'notify_url[^"]+"[^"]+' | head -1
 ```
 预期输出：`notify_url" value="https://YOUR_DOMAIN/payment/notify"`
 ### 3.3 验证支付宝密钥匹配
 ```bash
 # 确认密钥配置正确（生产用正式密钥，开发用沙箱密钥）
 ssh root@NEW_SERVER 'grep "ALIPAY_APP_ID\|ALIPAY_GATEWAY" /root/rust/rust_backend_*/env'
 ```
 | 环境 | APP_ID 前缀 | GATEWAY |
 |------|------------|---------|
 | 生产 | 202100... | `openapi.alipay.com` |
 | 开发 | 902100...（沙箱） | `openapi-sandbox.dl.alipaydev.com` |
 ### 3.4 验证关键端点
 ```bash
 # 支付页面可访问（非 503）
 curl -s -o /dev/null -w "%{http_code}" https://YOUR_DOMAIN/payment
 # 访客登录正常
 curl -s -X POST https://YOUR_DOMAIN/api/guest-login | python3 -c "import sys,json; print(json.load(sys.stdin).get('success','FAIL'))"
 # 健康检查
 curl -s https://YOUR_DOMAIN/health | python3 -c "import sys,json; print(json.load(sys.stdin).get('status','FAIL'))"
 ```
 ### 3.5 迁移后支付全链路测试
 ```bash
 bash tests/payment_e2e_test.sh
 ```
 ### 3.6 运行部署后测试
 ```bash
 export TEST_DOMAIN="https://YOUR_DOMAIN"
 ./deploy.sh production --skip-tests=false
 # 或手动运行
 export BASE_URL="https://YOUR_DOMAIN"
 bash lib/test.sh
 ```
 ## 阶段 4 — DNS 切换
 ### 4.1 更新 DNS 记录
 将域名指向新服务器 IP。
 ### 4.2 验证公网访问
 ```bash
 curl https://dev.xmclassmate.top/health
 curl https://xmclassmate.top/health
 curl https://xmclassmate.top/payment
 ```
-## 阶段 4 — 清理（可选）
+## 阶段 5 — 清理
 - 迁移 GlitchTip (Sentry)
 - 旧服务器保留 1 周作为回退
 - 确认无问题后关闭旧服务器
 ## 迁移检查清单

 | 2026-07-23 | 支付回调丢失 | `APP_BASE_URL` 未设置，默认指向 `dev.xmclassmate.top`，开发服务器无法通过 RSA2 验证 | 迁移清单第 6、8 项确保 base_url 配置正确 |
 | 2026-07-18 | 保存功能 500 | nginx AppArmor 缺少 `/var/lib/nginx/** rw` | 部署后测试 `test_nginx_proxy_temp` |
