# GHCS v0.2 · keys/page.tsx 完整可替换版（含登录入口+鉴权）

本页提供一份 **可直接全量替换** 的 `page.tsx` 代码：包含

- ✅ 登录入口（POST /api/login → localStorage.ghcs_access_token）
- ✅ 写操作自动带 Bearer（新增/编辑/启停/删除都不再 401）
- ✅ 去掉 `any`（满足 `@typescript-eslint/no-explicit-any`）
- ✅ token 初始化不使用 `setState in effect`（用 lazy initializer）

> 替换路径：`~/guanghu-dev/ghcs-mono/frontend/src/app/console/keys/page.tsx`

## 验收口径

- Network：`POST /api/login` → 200
- localStorage：`ghcs_access_token` 有值
- 启停：`PUT /api/keys/{id}` → 200（不再 401）
- 新增：`POST /api/keys/add` → 200
- 删除：`DELETE /api/keys/{id}` → 200
