• Axum 0.4.4

概念

参考：https://docs.rs/axum/latest/axum/index.html

示例

main.rs

use axum::{response::Html, routing::get, Router};
use std::net::SocketAddr;

#[tokio::main]
async fn main() {
    let app = Router::new()
        .route("/", get(home))
        .route("/hello", get(|| async { "hello" }))
        .route("/world", get(|| async { "world" }));

    let addr = SocketAddr::from(([127, 0, 0, 1], 4444));
    println!("listening on {addr}");
    axum::Server::bind(&addr)
        .serve(app.into_make_service())
        .await
        .unwrap();
}

async fn home() -> Html<&'static str> {
    Html("
hello world
")
}

总结

使用 axum 实现多个路由。
