goauth 0.7.0

rust-goauth [docs]

Crate for using OAuth 2.0 with Server to Server Applications for Google Cloud Engine, with tentative support for all supported Scopes. Supports sync or async requests via Futures.

Provides a serialisable Token struct for use in other applications that require authenticated interactions with Google Cloud.

Usage

#[macro_use]
extern crate log;

use goauth::auth::JwtClaims;
use goauth::scopes::Scope;
use goauth::{get_token, get_token_blocking, GoErr};
use goauth::credentials::Credentials;
use smpl_jwt::{RSAKey, Jwt};

fn main() -> Result<(), GoErr>{
  let token_url = "https://www.googleapis.com/oauth2/v4/token";
  let iss = "<some-iss>"; // https://developers.google.com/identity/protocols/OAuth2ServiceAccount

  let credentials = Credentials::from_file("dummy_credentials_file_for_tests.json").unwrap();
  let claims = JwtClaims::new(String::from(iss),
                             &Scope::DevStorageReadWrite,
                             String::from(token_url),
                             None, None);
  let jwt = Jwt::new(claims, credentials.rsa_key().unwrap(), None);

  // Use async
  let token = async {
    match get_token(&jwt, &credentials).await {
      Ok(token) => token,
      Err(e) => panic!(e)
    }
  };

  // Or sync
  let token = get_token_blocking(&jwt, &credentials)?;

  Ok(())
