路由和处理函数

• 需要启用 tokio 的macros和rt-multi-thread或full启用所有功能（cargo add tokio --features macros,rt-multi-thread）

[package]
name = "helloRust"
version = "0.1.0"
edition = "2024"

[dependencies]
axum = "0.8.4"
tokio = { version = "1.46.1", features = ["full"] }

路由

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

#[tokio::main]	// 用宏捏
async fn main() {

    // 多整点路由捏
    let app = Router::new()
        .route("/", get(root))
        .route("/foo", get(get_foo).post(post_foo))
        .route("/foo/bar", get(foo_bar));
    let listener = tokio::net::TcpListener::bind("0.0.0.0:3000").await.unwrap();
    axum::serve(listener, app).await.unwrap();
}
// 调用对应函数捏
async fn root() -> &'static str {"hey bro"}
async fn get_foo() -> &'static str {"what can i say"}
async fn post_foo() -> &'static str {"ohhohoboboboboooo"}
async fn foo_bar() -> &'static str {"整点无聊的？"}
