Web 框架的 SPA 功能集成

支持 Actix-web、Axum、Salvo 三大框架，通过统一的 spa! 宏将前端静态资源嵌入 Rust 二进制文件并提供 SPA 路由服务。

使用方法

添加依赖

# actix-web 框架
anycms-spa = { version = "*", features = ["actix"] }
# axum 框架
anycms-spa = { version = "*", features = ["axum"] }
# salvo 框架
anycms-spa = { version = "*", features = ["salvo"] }

# 注意：features 互斥，只能启用一个框架

# 由于 `rust-embed` 是过程宏，需要手动添加以下依赖
rust-embed = "8.9.0"
paste = "1.0.15"

spa! 宏使用

宏需要用在 main.rs 或者 lib.rs 文件中

/// spa!(名称, 资源路径, 路由前缀, [index 文件名称数组])
/// 路由前缀和 index 文件名数组可选
spa!(Spa, "assets");
/// 等价于
spa!(Spa, "assets", "/", ["index.html"]);

/// 带路由前缀的 Dashboard
spa!(Dashboard, "dashboard", "/dashboard", ["index.html"]);

示例代码

Actix-web 示例

use actix_web::{App, HttpResponse, HttpServer, Responder, get};
use anycms_spa::spa;
use tracing::info;

spa!(Spa, "assets", "/", ["index.html"]);
spa!(Dashboard, "dashboard", "/dashboard", ["index.html"]);

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    tracing_subscriber::fmt::init();
    info!("Hello, world!");
    HttpServer::new(|| {
        App::new()
            .service(index)
            .service(Dashboard::spa_service())
            .service(Spa::spa_service())
    })
    .bind("127.0.0.1:8080")?
    .run()
    .await?;
    Ok(())
}

#[get("/home")]
pub async fn index() -> impl Responder {
    HttpResponse::Ok().body("Hello world!")
}

Axum 示例

use anycms_spa::spa;
use axum::{routing::get, Router};

spa!(Spa, "assets");
spa!(Dashboard, "dashboard", "/dashboard", ["index.html"]);

#[tokio::main]
async fn main() {
    tracing_subscriber::fmt::init();

    let app = Router::new()
        .route("/home", get(root))
        .merge(Dashboard::spa_router())
        .merge(Spa::spa_router());

    let listener = tokio::net::TcpListener::bind("0.0.0.0:3000").await.unwrap();
    axum::serve(listener, app).await.unwrap();
}

async fn root() -> &'static str {
    "Hello, World!"
}

Salvo 示例

use anycms_spa::spa;
use salvo::prelude::*;

spa!(Spa, "assets");
spa!(Dashboard, "dashboard", "/dashboard", ["index.html"]);

#[handler]
async fn home(res: &mut Response) {
    res.render(Text::Plain("Hello, World!"));
}

#[tokio::main]
async fn main() {
    tracing_subscriber::fmt::init();

    let router = Router::new()
        .push(Router::with_path("/home").get(home))
        .push(Dashboard::spa_router())
        .push(Spa::spa_router());

    let listener = TcpListener::new("0.0.0.0:3000").bind().await;
    Server::new(listener).serve(router).await;
}

API 对比

路由行为

• 静态资源（JS/CSS/图片等）：直接返回，设置 Cache-Control: public, max-age=31536000
• HTML 页面：设置 Cache-Control: no-cache
• 未匹配路径：SPA fallback，返回 index.html，实现前端路由
• 路径遍历防护：自动拒绝包含 .. 的恶意路径
