Nginx 反向代理 404：proxy_pass 不带尾斜杠把 /api 前缀转发给后端

架构：前端 SPA → Nginx (80) → Node.js API (3000)。后端路由**不带** `/api` 前缀（如 `/hello`、`/users`、`/health`），前端统一通过 `fetch('/api/hello')` 经 Nginx 反代调用。

Go HTTP 服务 goroutine 泄漏：请求超时后后台 goroutine 永久阻塞（channel 发送阻塞）

生产环境 Go HTTP API 服务内存持续增长直至 OOM。用户请求 `/api/search` 接口，每次请求都设置 1 秒 context 超时，后台 goroutine 执行耗时的数据库查询（实际 2 秒），查询完成后将结果发送到**无缓冲 channel**。handler 因超时 1 秒先返回并退出，

MySQL 隐式类型转换导致索引失效：WHERE phone = 整数全表扫描、VARCHAR 列被转数值

团队维护的用户中心服务，核心表 `users` 有 20 万条用户数据。`phone` 字段定义为 `VARCHAR(20)` 并建立了索引 `idx_phone`。开发反馈「按手机号查用户特别慢」，但**同一个 SQL，就差一对引号**，性能天差地别：
