一、项目初始设置
```bash
npm create tauri-app@latest aln-tech-app -- --template react-ts
cd aln-tech-app
npm install axios
cargo add tauri-plugin-python
```
```toml:src-tauri/Cargo.toml
[dependencies]
tauri = { version = "2", features = ["protocol-asset"] }
tauri-plugin-python = "0.1" # 混合编程的核心依赖
serde = { version = "1", features = ["derive"] }
tokio = { version = "1", features = ["full"] }
reqwest = { version = "0.11", features = ["json"] }
tokio-postgres = "0.7"
[build-dependencies]
tauri-build = "2"
```
二、技术混合详解：Python与Rust的三种协作方案
以下三种方案中，优先推荐方案一
🔵 方案一：使用 tauri-plugin-python 插件（最简洁、文档完整）
```rust:src-tauri/src/main.rs
#[cfg_attr(mobile, tauri::mobile_entry_point)]
pub fn run() {
tauri::Builder::default()
.plugin(tauri_plugin_python::init()) // 初始化Python插件，与Rust通信
.invoke_handler(tauri::generate_handler![
call_python_analyzer,
sync_material_data
])
.run(tauri::generate_context!())
.expect("启动AlN交流平台失败");
}
#[tauri::command]
async fn call_python_analyzer(app: tauri::AppHandle, param: String) -> Result<String, String> {
let result = tauri_plugin_python::eval_blocking(&app, &format!(r#"
from aln_ml import PropertyPredictor
predictor = PropertyPredictor.load()
predictor.predict_thermal_conductivity('{}')
"#, param)).map_err(|e| e.to_string())?;
Ok(result)
}
```
🟢 方案二：PyO3 原生绑定（高性能AI推理）
```rust:aln-binding/src/lib.rs
use pyo3::prelude::*;
#[pyclass] // 该Rust结构体将在Python中可见
pub struct MaterialDatabase { /* 模拟高性能索引字段 */ }
#[pymethods]
impl MaterialDatabase {
#[new] // Python的构造函数
fn new() -> Self { Self {} }
fn search_by_property(&self, thermal: f64, bandgap: f64) -> Vec<String> {
// 氮化铝材料快速查询模拟：当热导率 > 200 W/mK 且带宽约 6.2 eV 时触发
if thermal > 200.0 && bandgap > 6.0 && bandgap < 6.5 {
vec!["AlN_Substrate_001".to_string(), "AlN_Coating_Al2O3".to_string()]
} else { vec![] }
}
}
#[pymodule]
fn aln_material_lib(_py: Python, m: &PyModule) -> PyResult<()> {
m.add_class::<MaterialDatabase>()?; // 导出类
Ok(())
}
```
⚠️ 注意：使用PyO3会增大安装包体积，且第三方pyo3 crate版本需与Rust编译器匹配。
🟡 方案三：Rust 调用 Python（传统 FFI）
```rust:src/embed_python.rs
use std::process::Command;
#[tauri::command]
fn run_python_script(script_path: &str, args: Vec<String>) -> Result<String, String> {
let output = Command::new("python3")
.arg(script_path).args(args)
.output().map_err(|e| e.to_string())?;
String::from_utf8(output.stdout).map_err(|e| e.to_string())
}
```
三、数据库与API实现
Rust 端：数据库与网络层
```rust:src-tauri/src/database.rs
use tokio_postgres::{NoTls, Client, Error};
pub async fn connect_db() -> Result<Client, Error> {
let (client, connection) = tokio_postgres::connect(
"host=localhost user=aln_user dbname=aln_tech password=securepass",
NoTls,
).await?;
tokio::spawn(async move { if let Err(e) = connection.await { eprintln!("DB连接错误: {}", e); } });
Ok(client)
}
#[tauri::command]
async fn get_materials(client: tauri::State<'_, Client>) -> Result<Vec<Material>, String> {
let rows = client.query("SELECT id, name, thermal_conductivity FROM materials", &[]).await.unwrap();
Ok(rows.iter().map(|row| Material { id: row.get(0), name: row.get(1), thermal_conductivity: row.get(2) }).collect())
}
#[tauri::command]
async fn sync_news() -> Result<Vec<AlnNews>, String> {
let response = reqwest::get("https://api.aln-industry.com/v1/news?type=industry")
.await.unwrap().json::<Vec<AlnNews>>().await.unwrap();
Ok(response)
}
```
TypeScript 前端：通用调用模板
```typescript:src/services/api.ts
import { invoke } from "@tauri-apps/api/core";
import axios from "axios";
export const tauriCommand = <T>(cmd: string, args?: Record<string, unknown>): Promise<T> => invoke<T>(cmd, args);
export const alnAPI = axios.create({ baseURL: "https://api.aln-industry.com", timeout: 10000 });
alnAPI.interceptors.response.use(res => res, error => console.error("API Error:", error));
export const fetchMaterials = () => tauriCommand<Material[]>("get_materials");
export const syncNews = () => tauriCommand<AlnNews[]>("sync_news");
export const fetchLatestNews = () => alnAPI.get<AlnNews[]>("/v1/news?type=industry");
```
四、前端UI开发（React + TypeScript）
氮化铝资讯看板
```tsx:src/pages/Dashboard.tsx
import { useState, useEffect } from "react";
import { fetchLatestNews, syncNews } from "../services/api";
export function Dashboard() {
const [news, setNews] = useState<AlnNews[]>([]);
const [loading, setLoading] = useState(true);
useEffect(() => { fetchLatestNews().then(res => { setNews(res.data); setLoading(false); }); }, []);
const handleSync = async () => { setLoading(true); await syncNews(); await fetchLatestNews(); setLoading(false); };
return (<div>
<button onClick={handleSync} className="bg-blue-600 text-white p-2 rounded">🔄 手动同步产业动态</button>
{loading ? <p>加载AlN数据中...</p> : news.map(item => (<div key={item.id}><h3>{item.title}</h3><p>{new Date(item.date).toLocaleDateString()}</p><p>{item.summary}</p></div>))}
</div>);
}
```
技术交流社区
```tsx:src/pages/Community.tsx
import { useState, useEffect } from "react";
import { tauriCommand } from "../services/api";
export function Community() {
const [posts, setPosts] = useState<Post[]>([]);
const [newPost, setNewPost] = useState("");
useEffect(() => { tauriCommand<Post[]>("get_posts").then(setPosts); }, []);
const submitPost = async () => {
await tauriCommand("create_post", { content: newPost });
const updated = await tauriCommand<Post[]>("get_posts");
setPosts(updated);
setNewPost("");
};
return (<div>
<div><textarea value={newPost} onChange={(e) => setNewPost(e.target.value)} placeholder="分享AlN工艺心得或提问..." /></div>
<button onClick={submitPost}>发布技术贴</button>
{posts.map(post => (<div key={post.id}><strong>{post.author}</strong><p>{post.content}</p></div>))}
</div>);
}
```
五、打包与发布
修改配置文件以包含Python资源，然后执行 npm run tauri build：
```json:src-tauri/tauri.conf.json
{ "build": { "beforeDevCommand": "npm run dev", "beforeBuildCommand": "npm run build" }, "bundle": { "active": true, "resources": { "../src-python": "./python" } } }
```
