Logging

提供基本的 Log 功能的中間件. 如果中間件直接添加到了 Router 上，它將無法捕獲所有 Router 都不匹配時返回的 404 錯誤，建議添加到 Service 上.

示例代碼

use salvo::logging::Logger;
use salvo::prelude::*;

#[handler]
async fn hello() -> &'static str {
    "Hello World"
}

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

    let router = Router::new().get(hello);
    let service = Service::new(router).hoop(Logger::new());

    let acceptor = TcpListener::new("0.0.0.0:5800").bind().await;
    Server::new(acceptor).serve(service).await;
}
