【Axum】获取路径参数

环境

• Time 2022-01-16
• Rust 1.58.0
• Axum 0.4.4

概念

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

示例

main.rs

use axum::{extract::Path, routing::get, Router};
use std::net::SocketAddr;

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

    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(Path(name): Path) -> String {
    println!("{:#?}", name);
    name
}

多个路径参数

use axum::{extract::Path, routing::get, Router};
use std::net::SocketAddr;

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

    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(Path((name, id)): Path<(String, usize)>) -> String {
    format!("name: {name}, id: {id}")
}

总结

获取请求中的路径参数。
