Examples
use hyper::{Body, Request, Response, Server}; use routerify::{Router, RouterService}; // Import the query_parser function and the RequestQueryExt trait. use routerify_query::{query_parser, RequestQueryExt}; use std::{convert::Infallible, net::SocketAddr}; // A handler for "/" page. Visit: "/?username=Alice&bookname=HarryPotter" to see query values. async fn home_handler(req: Request<Body>) -> Result<Response<Body>, Infallible> { // Access the query values. let user_name = req.query("username").unwrap(); let book_name = req.query("bookname").unwrap(); Ok(Response::new(Body::from(format!( "User: {}, Book: {}", user_name, book_name )))) } // Create a router. Router::builder() // Attach the query_parser middleware. .middleware(query_parser()) .get("/", home_handler) .build() .unwrap() }
