What is this?

If you have a Rust server and plan to have API for your verifying your firebase users' client token, then it's just for you!

It only contains small utility to decode your client token.

Flow

1. In your frontend, you can get your uid by using Firebase Client SDK.

   Sample: https://firebase.google.com/docs/auth/admin/verify-id-tokens#retrieve_id_tokens_on_clients

2. Then your frontend can hit the backend Rust API, and send hover the header/POST body (up to you)

3. Backend Rust will verify and send back the JWL claim response (including extracted user's data) back as json

How to use

use firebase_jwt_rs::*;
use jsonwebtoken::TokenData;
use std::error::Error;

let uid = "your-user-uid";
let client_token = "your-client-token";

const result: Result<TokenData<Claims>, Box<dyn Error>> = verify_token(uid, client_token);

match result {
  Ok(res: TokenData<Claims>) => {
    let text: String = serde_json::to_string(&res.claims).unwrap();
    println!("result:{text}");
  }
  Err(e) => {
    println!("err:{e}");
  }
}
