tlns-google-oauth2

A server-side Google OAuth2 authentication with built in scopes for extra type safety.

Generating scopes enums (for proc macro library part only)

Go to Google's OAuth2 Scopes Listing and start copying from the first header to the final row of the table at the bottom of the document. Then pasting all of that to the info.txt and build the library, it will give you all possible scopes!

Usage ([crate::grouped_scopes])

use tlns_google_oauth2::GoogleOAuth2Client as Client;
use tlns_google_oauth2::scopes;
let client = Client::new("CLIENT_ID".to_string(), "CLIENT_SECRET".to_string(), "http://localhost:8080/callback".to_string()).expect("Failed to build client");
let auth = client.authorize_url(None, vec![&scopes::GoogleOAuth2APIv2::AuthUserinfoProfile]).unwrap();
let url = auth.0;
let csrf_token = auth.1;
let scopes = auth.2;

// ... Callback codes here (You can't save states in oauth2 crate for some reasons :( )

let code = "...";
let token = client.get_token(code.to_string()).await.unwrap();
// Do request stuff

Usage ([crate::scopes::Scopes])

use tlns_google_oauth2::GoogleOAuth2Client as Client;
use tlns_google_oauth2::scopes;
let client = Client::new("CLIENT_ID".to_string(), "CLIENT_SECRET".to_string(), "http://localhost:8080/callback".to_string()).expect("Failed to build client");
let auth = client.authorize_url(None, vec![&scopes::Scopes::AuthUserinfoProfile]).unwrap();
let url = auth.0;
let csrf_token = auth.1;
let scopes = auth.2;

// ... Callback codes here (You can't save states in oauth2 crate for some reasons :( )

let code = "...";
let token = client.get_token(code.to_string()).await.unwrap();
// Do request stuff

Thanks heapunderfl0w for the proc macro idea instead of shitty Jinja2 implementation!
