Module tower_async_http::sensitive_headers

source ·
Available on crate feature sensitive-headers only.
Expand description

Middlewares that mark headers as sensitive.

Example

use tower_async_http::sensitive_headers::SetSensitiveHeadersLayer;
use tower_async::{Service, ServiceExt, ServiceBuilder, service_fn};
use http::{Request, Response, header::AUTHORIZATION};
use hyper::Body;
use std::{iter::once, convert::Infallible};

async fn handle(req: Request<Body>) -> Result<Response<Body>, Infallible> {
    // ...
}

let mut service = ServiceBuilder::new()
    // Mark the `Authorization` header as sensitive so it doesn't show in logs
    //
    // `SetSensitiveHeadersLayer` will mark the header as sensitive on both the
    // request and response.
    //
    // The middleware is constructed from an iterator of headers to easily mark
    // multiple headers at once.
    .layer(SetSensitiveHeadersLayer::new(once(AUTHORIZATION)))
    .service(service_fn(handle));

// Call the service.
let response = service
    .call(Request::new(Body::empty()))
    .await?;
