Request Id

Request Id 中間件是比較靈活的，生成器(IdGenerator) 用於生成 ID, 可以定義自己的 ID 生成器，隻要實現 IdGenerator 這個 trait. 默認提供生成器是 UlidGenerator.

另外你可以控製是否覆蓋現在的已經存在的 requestid. 還可以設置 header_name 等, 具體請查看文檔.

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;
}
