iron_requestid
Iron middleware for generating unique IDs for requests.
This crate uses UUID4 generated IDs for requests. After installing the middleware, request IDs can be accessed in a request handler like so:
fn request_handler(request: &mut Request) -> IronResult<Response> {
// ...
let request_id = request.extensions.get::<RequestId>().unwrap();
// ...
}
There is an example service that installs this middleware and retrieves a request's ID. The code for this is in examples/service.rs. Run the example service and send it a request to test it:
cargo run --example service &
curl localhost:3000/foo
The example service's source code is also shown below:
extern crate iron;
extern crate iron_requestid;
use iron::prelude::*;
use iron::status::Status;
use iron_requestid::{RequestId, RequestIds};
fn main() {
let mut chain = Chain::new(return_request_handler);
let (request_ids_before, request_ids_after) = RequestIds::new();
chain.link_before(request_ids_before);
chain.link_after(request_ids_after);
Iron::new(chain).http("127.0.0.1:3000").unwrap();
}
fn return_request_handler(request: &mut Request) -> IronResult<Response> {
match request.extensions.get::<RequestId>() {
Some(id) => Ok(Response::with((
Status::Ok,
id.to_string()))),
None => Ok(Response::with((
Status::InternalServerError,
"could not get request ID")))
}
}
