```rust extern crate smpl_jwt; extern crate goauth;
extern crate log;
use goauth::auth::JwtClaims; use goauth::scopes::Scope; use goauth::gettoken; use smpljwt::{RSAKey, Jwt};
fn main() { let tokenurl = "https://www.googleapis.com/oauth2/v4/token"; let iss = "someiss"; // https://developers.google.com/identity/protocols/OAuth2ServiceAccount let privatekeyfile = "randomrsafor_testing";
let claims = JwtClaims::new(String::from(iss), Scope::DevStorageReadWrite, String::from(tokenurl), None, None); let key = match RSAKey::frompem(privatekeyfile) { Ok(x) => x, Err(e) => panic!("{}", e) }; let jwt = Jwt::new(claims, key, None); match get_token(&jwt, None) { Ok(x) => debug!("{}", x), Err(e) => debug!("{}", e) }; } ```
