Actix utilities for interacting with aliri authorities

Usage

In order to attach the validator to Actix, you will first need to

Example

use aliri::{jwa, jwk, jwt, jwt::CoreClaims as _, Jwk, Jwks};
use aliri_actix::scope_policy;
use aliri_base64::Base64UrlRef;
use aliri_clock::UnixTime;
use aliri_oauth2::{oauth2, Authority};
use actix_web::{get, web, http::{header, StatusCode}, test, App, HttpResponse, Responder};
use futures::executor::block_on;
use serde::Deserialize;

#[derive(Clone, Debug, Deserialize)]
pub struct CustomClaims {
iss: jwt::Issuer,
aud: jwt::Audiences,
sub: jwt::Subject,
scope: oauth2::Scope,
}

impl jwt::CoreClaims for CustomClaims {
fn nbf(&self) -> Option<UnixTime> { None }
fn exp(&self) -> Option<UnixTime> { None }
fn aud(&self) -> &jwt::Audiences { &self.aud }
fn iss(&self) -> Option<&jwt::IssuerRef> { Some(&self.iss) }
fn sub(&self) -> Option<&jwt::SubjectRef> { Some(&self.sub) }
}

impl oauth2::HasScope for CustomClaims {
fn scope(&self) -> &oauth2::Scope { &self.scope }
}

// Define our initial scope
scope_policy!(AdminOnly / AdminOnlyScope (CustomClaims); "admin");

// Define an endpoint that will require this scope
#[get("/test")]
async fn test_endpoint(token: AdminOnly) -> impl Responder {
println!("Token subject: {}", token.claims().sub);
HttpResponse::Ok()
}

fn construct_authority() -> Authority {
// This authority might otherwise come from a well-known JWKS endpoint
let secret = Base64UrlRef::from_slice(b"test").to_owned();
let key = Jwk::from(jwa::Hmac::new(secret))
.with_algorithm(jwa::Algorithm::HS256)
.with_key_id(jwk::KeyId::new("test key"));

let mut jwks = Jwks::default();
jwks.add_key(key);

let validator = jwt::CoreValidator::default()
.ignore_expiration() // Only for demonstration purposes
.add_approved_algorithm(jwa::Algorithm::HS256)
.add_allowed_audience(jwt::Audience::new("my_api"))
.require_issuer(jwt::Issuer::new("authority"));

Authority::new(jwks, validator)
}

// Construct our authority
let authority = construct_authority();

# actix_rt::Runtime::new().unwrap().block_on(async move {
// Construct the server, providing the authority as `app_data`
let mut app = test::init_service(
App::new()
.app_data(authority.clone())
.service(test_endpoint)
).await;

// Use a good token

let token = concat!(
"eyJhbGciOiJIUzI1NiIsImtpZCI6InRlc3Qga2V5In0.",
"eyJzdWIiOiJBbGlyaSIsImF1ZCI6Im15X2FwaSIsImlzcyI6ImF1dGhvcml0eSIsInNjb3BlIjoiYWRtaW4ifQ.",
"Bql6D5kZiqQaW77M8J19jE8TuE3U51MiHjRBU_8NeeQ",
);

let req = test::TestRequest::with_uri("/test")
.header(header::AUTHORIZATION, format!("Bearer {}", token))
.to_request();

let mut resp = test::call_service(&mut app, req).await;
assert_eq!(resp.status(), StatusCode::OK);

// Use a bad token

let bad_token = concat!(
"eyJhbGciOiJIUzI1NiIsImtpZCI6InRlc3Qga2V5In0.",
"eyJzdWIiOiJBbGlyaSIsImF1ZCI6Im15X2FwaSIsImlzcyI6ImF1dGhvcml0eSIsInNjb3BlIjoidXNlciJ9.",
"n7SKlWcaNj6KP-e6pQdFFubbkqjEwEHzmoL2PVoxm2I",
);

let req = test::TestRequest::with_uri("/test")
.header(header::AUTHORIZATION, format!("Bearer {}", bad_token))
.to_request();

let mut resp = test::call_service(&mut app, req).await;
assert_eq!(resp.status(), StatusCode::FORBIDDEN);

// Use a malformed token

let req = test::TestRequest::with_uri("/test")
.header(header::AUTHORIZATION, "Bearer totally-not-a-jwt")
.to_request();

let mut resp = test::call_service(&mut app, req).await;
assert_eq!(resp.status(), StatusCode::UNAUTHORIZED);
