# routerify-query
A [`Routerify`](https://github.com/routerify/routerify) middleware which parses the request query string and populates in the `req` object.
[Docs](https://docs.rs/routerify-query)
## Install
Add this to your `Cargo.toml`:
```toml
[dependencies]
routerify = "1.0"
routerify-query = "1.0"
```
## Example
```rust
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.
fn router() -> Router<Body, Infallible> {
Router::builder()
// Attach the query_parser middleware.
.middleware(query_parser())
.get("/", home_handler)
.build()
.unwrap()
}
#[tokio::main]
async fn main() {
let router = router();
// Create a Service from the router above to handle incoming requests.
let service = RouterService::new(router);
// The address on which the server will be listening.
let addr = SocketAddr::from(([127, 0, 0, 1], 3001));
// Create a server by passing the created service to `.serve` method.
let server = Server::bind(&addr).serve(service);
println!("App is running on: {}", addr);
if let Err(err) = server.await {
eprintln!("Server error: {}", err);
}
}
```
