actix-request-identifier implements a middleware for
actix-web that generates an ID for each
incomming request. By default, a UUID v4 is generated for each request using
uuid. The request ID is set via the
x-request-id HTTP header (which can be configured) and can be extracted from
the request using RequestId.
```rust use actixrequestidentifier::{RequestId, RequestIdentifier}; use actix_web::{get, App, HttpServer, Responder};
async fn showrequestid(id: RequestId) -> impl Responder { format!("{}", id.as_str()) }
async fn main() -> std::io::Result<()> { HttpServer::new(|| { App::new() .service(showrequestid) .wrap(RequestIdentifier::with_uuid()) }) .bind(("127.0.0.1", 8080))? .run() .await } ```
The response looks like this:
``` $ curl -i 127.0.0.1:8080/ HTTP/1.1 200 OK content-length: 36 x-request-id: 5f099854-2117-49b3-b252-d6693a85acc5 date: Mon, 20 Apr 2020 06:53:49 GMT
5f099854-2117-49b3-b252-d6693a85acc5 ```
