iron-params

Request parameters extension for the Iron web framework.

iron-params is a fast, convenient, and flexible extension for Iron Request. It allows retriving query/form params from iron request and convert into the type you want.

Example

extern crate iron;
extern crate iron_params as params;
use iron::prelude::*;
use params::*;

// To run, $ cargo run --example simple
// to use, $ curl -d "ids=1,2,3&channel=1" "http://localhost:3000/?ids=4,5,6,"

fn main() {
    let mut chain = Chain::new(handler);
    chain.link_before(params::Params {});
    Iron::new(chain).http("localhost:3000").unwrap();
}

fn handler(req: &mut Request) -> IronResult<Response> {
    let mut content = String::new();

    let ids = req.params("ids");
    content.push_str(&format!("ids:{:?}\n", ids));

    let channel = req.param::<i32>("channel");
    content.push_str(&format!("channel:{:?}\n", channel));

    let channel = req.param::<String>("channel");
    content.push_str(&format!("channel:{:?}\n", channel));

    let channel = req.param::<f32>("channel");
    content.push_str(&format!("channel:{:?}\n", channel));


    Ok(Response::with((iron::status::Ok, content)))
}
