Rust Axum 高性能 API 与中间件/日志追踪实践

示例代码（main.rs）：use axum::{routing::get, Router, response::IntoResponse};

use tower_http::trace::TraceLayer;

async fn ping() -> impl IntoResponse {

(axum::http::StatusCode::OK, "{\"pong\":true}")

}

#[tokio::main]

async fn main() {

tracing_subscriber::fmt::init();

let app = Router::new()

.route("/api/ping", get(ping))

.layer(TraceLayer::new_for_http());

let listener = tokio::net::TcpListener::bind("0.0.0.0:3000").await.unwrap();

axum::serve(listener, app).await.unwrap();

}
