+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
+
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
+
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```

+# InternetProject 后端（Rust）
+
+系统监控后端：每秒采集 CPU 使用率、内存使用率、内存总量与可用内存，
+格式化成字符串，通过 HTTP 接口提供给 **React 前端**（顶部栏每秒刷新展示）。
+接口按使用方分区，并为未来的 **.NET 客户端**预留了独立区域。
+
+技术栈：`axum` 0.8 + `tokio` + `sysinfo` + `serde` + `tower-http`(cors)。
+
+---
+
+## 1. 整体架构与数据流
+
+```
+                         ┌──────────────────────────────┐
+   每秒采样               │  后台任务 run_sampler (tokio)  │
+   ┌────────────┐ write  │  sysinfo::System 刷新指标       │
+   │  sysinfo   │───────►│  → Stats → 写入共享快照          │
+   └────────────┘        └──────────────┬───────────────┘
+                                         │ Arc<RwLock<Stats>>
+                                         ▼  read
+   浏览器(React)  GET /api/web/stats   ┌─────────────┐
+   localhost:5173 ───────────────────►│  axum 路由   │  CORS 放行前端源
+                  ◄─── JSON(Stats) ────│  0.0.0.0:8080│
+                                       └─────────────┘
+   .NET 客户端   GET /api/client/*  ───►   同一服务，不同接口区（无 CORS）
+```
+
+**关键设计**：采样（写）与请求（读）解耦。后台任务持有 `sysinfo::System`
+每秒刷新一次并写入一个 `RwLock` 保护的快照；HTTP handler 只读快照、
+立即返回，不会因为采集系统指标而阻塞请求。
+
+---
+
+## 2. 逐文件说明（`src/`）
+
+| 文件 | 职责 |
+|------|------|
+| `main.rs` | 入口。建 `AppState` → `tokio::spawn` 采样任务 → 构建路由 → 绑定 `0.0.0.0:8080` → `axum::serve`。 |
+| `monitor.rs` | `Stats` 数据结构、格式化、后台采样循环 `run_sampler`。 |
+| `state.rs` | `AppState`：被 `Arc<RwLock<…>>` 包裹的共享快照，可廉价 clone。 |
+| `routes/mod.rs` | 组装并合并 `web` / `client` 两个子路由。 |
+| `routes/web.rs` | 前端接口 `GET /api/web/stats`，**挂 CORS**。 |
+| `routes/client.rs` | 未来 .NET 客户端接口区，目前 `GET /api/client/health` 占位，**不挂 CORS**。 |
+
+### `monitor.rs` 要点
+
+- **`Stats`**：`#[serde(rename_all = "camelCase")]`，序列化为
+  `text` / `cpu` / `memUsedPct` / `memTotalBytes` / `memAvailableBytes`。
+  `text` 是给 UI 直接展示的字符串，其余原始字段留给后续可视化。
+- **CPU 使用率需要两次刷新**：`sysinfo` 的 CPU 占用率是两次刷新之间的差值。
+  所以 `run_sampler` 先 `refresh_cpu_usage()` 预热一次，等待
+  `MINIMUM_CPU_UPDATE_INTERVAL`，之后再进入「每秒刷新」循环，读数才准确。
+- **内存单位**：`sysinfo` 返回**字节**。`used = total - available`，
+  百分比 = `used / total * 100`，展示时换算 GB。
+
+### `state.rs` 要点
+
+- `Arc` 让状态在「采样任务」和「每个请求」之间共享；
+  `RwLock` 允许多读单写（这里是单写者 + 偶发读者）。
+- handler 里 `state.snapshot.read().await.clone()` 取一份快照副本后立刻释放锁。
+
+---
+
+## 3. CORS：为什么前端要、客户端不要
+
+**CORS（跨源资源共享）是浏览器的安全机制**，由浏览器强制执行：
+
+- React 前端运行在浏览器里，页面源是 `http://localhost:5173`，
+  而后端是 `http://localhost:8080` —— **协议/host/port 任一不同即为「跨源」**。
+  浏览器默认禁止 JS 读取跨源响应，除非后端在响应里带上
+  `Access-Control-Allow-Origin` 等头声明「我允许这个源」。
+  所以 `web.rs` 用 `tower-http` 的 `CorsLayer` 放行前端源：
+
+  ```rust
+  let cors = CorsLayer::new()
+      .allow_origin(AllowOrigin::list([
+          "http://localhost:5173".parse().unwrap(),
+          "http://127.0.0.1:5173".parse().unwrap(),
+      ]))
+      .allow_methods([Method::GET]);
+  ```
+
+- **.NET 客户端不是浏览器**（用 `HttpClient` 直接发请求），
+  不存在「同源策略」，也不会发 CORS 预检、不校验响应头。
+  因此 `client.rs` **不挂 CORS** —— 加了也无意义。
+
+> 一句话：CORS 只拦浏览器。给前端配，给客户端不用配。
+
+部署到生产、前端由后端托管成同源时，CORS 也不会碍事；若前端换了域名，
+只需在 `allow_origin` 列表里加上新源。
+
+---
+
+## 4. 接口分区（前端 vs 客户端不共用接口）
+
+两类调用方走**不同的路径前缀**，在代码里也是不同的子路由模块，便于各自演进、
+施加不同中间件（如 CORS、认证）：
+
+| 区域 | 前缀 | 使用方 | CORS |
+|------|------|--------|------|
+| Web | `/api/web/*` | React 前端（浏览器） | ✅ 放行前端源 |
+| Client | `/api/client/*` | 未来 .NET 客户端 | ❌ 不需要 |
+
+---
+
+## 5. API 参考
+
+### `GET /api/web/stats`  （前端）
+```json
+{
+  "text": "CPU 4.4% · MEM 48.3% · 15.2/31.4 GB · Free 16.2 GB",
+  "cpu": 4.39,
+  "memUsedPct": 48.35,
+  "memTotalBytes": 33664409600,
+  "memAvailableBytes": 17387958272
+}
+```
+
+### `GET /api/client/health`  （客户端占位）
+```json
+{ "status": "ok" }
+```
+
+---
+
+## 6. 运行
+
+```bash
+# 拉依赖若慢，先给 cargo 设代理：
+# export http_proxy=http://127.0.0.1:7890 https_proxy=http://127.0.0.1:7890
+
+cd Server
+cargo run            # 监听 http://0.0.0.0:8080
+```
+
+快速自测：
+```bash
+curl http://localhost:8080/api/web/stats
+curl http://localhost:8080/api/client/health
+# 验证 CORS 头：
+curl -i -H "Origin: http://localhost:5173" http://localhost:8080/api/web/stats | grep -i access-control
+```
+
+前端：`cd Client && npm run dev`，浏览器开 `http://localhost:5173`，
+顶部栏会每秒刷新系统状态字符串（后端没开时回退到默认文案、状态点变暗）。
+
+---
+
+## 7. 未来 .NET 客户端如何连接
+
+客户端走 `/api/client/*`，不受 CORS 影响，直接请求即可：
+
+```csharp
+using var http = new HttpClient { BaseAddress = new Uri("http://<server-host>:8080") };
+var resp = await http.GetStringAsync("/api/client/health");
+// => {"status":"ok"}
+```
+
+后续把客户端要的功能加到 `routes/client.rs` 即可，与前端接口互不影响。
