limiter

This is an example of BeforeMiddleware for the Iron framework. It limits the request body size by checking first the Content-Length header, then the size of the payload. The response is either an HTTP 413 or it continues down the chain.

It will also set an upper bound on the length of a URL which can be helpful in regular GET requests.

Include this in your Cargo.toml file:

[dependencies]
limiter = "0.3"

Example

extern crate iron;
extern crate limiter;

use iron::prelude::*;

use limiter::RequestLimit;

fn index(_: &mut Request) -> IronResult<Response> {
    Ok(Response::with((iron::status::Ok, "Test")))
}

fn main() {
    let max_request = RequestLimit::default();
    let mut chain = Chain::new(index);
    chain.link_before(max_request);
    Iron::new(chain).http("localhost:3000").unwrap();
}
