Examples

Actix

https://github.com/trchopan/firebase-auth/tree/main/examples/actix_basic.rs

use actix_web::{get, middleware::Logger, web::Data, App, HttpServer, Responder};
use firebase_auth::{FirebaseAuth, FirebaseUser};

// Use `FirebaseUser` extractor to verify the user token and decode the claims
#[get("/hello")]
async fn greet(user: FirebaseUser) -> impl Responder {
    let email = user.email.unwrap_or("empty email".to_string());
    format!("Hello {}!", email)
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    let firebase_auth = FirebaseAuth::new("my-project-id").await;

    let app_data = Data::new(firebase_auth);

    HttpServer::new(move || {
        App::new()
            .wrap(Logger::default())
            .app_data(app_data.clone())
            .service(greet)
    })
    .bind(("127.0.0.1", 8080))?
    .run()
    .await
}

Axum

https://github.com/trchopan/firebase-auth/tree/main/examples/axum_basic.rs

use axum::{routing::get, Router};
use firebase_auth::{FirebaseAuth, FirebaseAuthState, FirebaseUser};

async fn greet(current_user: FirebaseUser) -> String {
    let email = current_user.email.unwrap_or("empty email".to_string());
    format!("hello {}", email)
}

async fn public() -> &'static str {
    "ok"
}

#[tokio::main]
async fn main() {
    let firebase_auth = FirebaseAuth::new("my-project-id").await;

    let app = Router::new()
        .route("/hello", get(greet))
        .route("/", get(public))
        .with_state(FirebaseAuthState { firebase_auth });

    let addr = &"127.0.0.1:8080".parse().expect("Cannot parse the addr");
    axum::Server::bind(addr)
        .serve(app.into_make_service())
        .await
        .unwrap()
}

How to call the endpoint with Bearer Token

Obtain the Bearer token

Use firebase sdk to get the User Token.

For example: getIdToken()

Request the endpoint with Authorization Bearer

Make the request using the User's token. Note that it will expire so you will need to get it again if expired.

TOKEN="<paste your token here>"

curl --header "Authorization: Bearer $TOKEN" http://127.0.0.1:8080/hello
