## 📁 部署

下载这个文件，然后拖到 VS Code 里替换：

[keys-page.tsx](GHCS%20v0%202%20%C2%B7%20keys%20page%20tsx%20%C2%B7%20API%E5%AF%86%E9%92%A5%E7%AE%A1%E7%90%86%E5%89%8D%E7%AB%AF/keys-page.tsx)

keys-page.tsx

或者终端里执行：

```bash
base64 -d << 'B64END' > ~/guanghu-dev/ghcs-mono/frontend/src/app/console/keys/page.tsx
base64_data
B64END
```

保存后刷新 [http://localhost:3000/console/keys](http://localhost:3000/console/keys)
