openid_client

Build Status

Library for working with OpenID Connect and implementing clients.

It currently supports these features:

  • discover OpenID Provider metadata
  • parsing and validating id tokens
  • basic tools for implementing implicit and authorization code flow
  • authentication for command line tools

Besides authentication providers that support OpenID Connect, this library can also work with other authentication providers supporting oauth2, like Facebook. For these providers, some features (e.g. discovery and id tokens) will not work. You should define the metadata for those providers manually, except for Facebook, which is predefined in the library.

Usage

A simple usage example:

import 'package:openid_client/openid_client.dart';

main() async {

  // print a list of known issuers
  print(Issuer.knownIssuers);

  // discover the metadata of the google OP
  var issuer = await Issuer.discover(Issuer.google);
  
  // create a client
  var client = new Client(issuer, "client_id", "client_secret");
  
  // create a credential object from authorization code
  var c = client.createCredential(code: "some received authorization code");

  // or from an access token
  c = client.createCredential(accessToken: "some received access token");

  // or from an id token
  c = client.createCredential(idToken: "some id token");      

  // get userinfo
  var info = await c.getUserInfo();
  print(info.name);
  
  // get claims from id token if present
  print(c.idToken?.claims?.name);
  
  // create an implicit authentication flow
  var f = new Flow.implicit(client);
  
  // or an explicit flow
  f = new Flow.authorizationCode(client);
  
  // set the redirect uri
  f.redirectUri = Uri.parse("http://localhost");
  
  // do something with the authentication url
  print(f.authenticationUrl);
  
  // handle the result and get a credential object
  c = await f.callback({
    "code": "some code",
  });
  
  // validate an id token
  var violations = await c.validateToken();
}

Usage example on flutter

// import the io version
import 'package:openid_client/openid_client_io.dart';
// use url launcher package 
import 'package:url_launcher/url_launcher.dart';

authenticate(Uri uri, String clientId, List<String> scopes) async {   
    
    // create the client
    var issuer = await Issuer.discover(uri);
    var client = new Client(issuer, clientId);
    
    // create a function to open a browser with an url
    urlLauncher(String url) async {
        if (await canLaunch(url)) {
          await launch(url, forceWebView: true);
        } else {
          throw 'Could not launch $url';
        }
    }
    
    // create an authenticator
    var authenticator = new Authenticator(client,
        scopes: scopes,
        port: 4000, urlLancher: urlLauncher);
    
    // starts the authentication
    var c = await authenticator.authorize();
    
    // close the webview when finished
    closeWebView();
    
    // return the user info
    return await c.getUserInfo();

}

Usage example on command line

// import the io version
import 'package:openid_client/openid_client_io.dart';

authenticate(Uri uri, String clientId, List<String> scopes) async {   
    
    // create the client
    var issuer = await Issuer.discover(uri);
    var client = new Client(issuer, clientId);
    
    // create an authenticator
    var authenticator = new Authenticator(client,
        scopes: scopes,
        port: 4000);
    
    // starts the authentication
    var c = await authenticator.authorize(); // this will open a browser
    
    // return the user info
    return await c.getUserInfo();
}

Usage example in browser

// import the browser version
import 'package:openid_client/openid_client_browser.dart';

authenticate(Uri uri, String clientId, List<String> scopes) async {   
    
    // create the client
    var issuer = await Issuer.discover(uri);
    var client = new Client(issuer, clientId);
    
    // create an authenticator
    var authenticator = new Authenticator(client, scopes: scopes);
    
    // get the credential
    var c = await authenticator.credential;
    
    if (c==null) {
      // starts the authentication
      authenticator.authorize(); // this will redirect the browser
    } else {
      // return the user info
      return await c.getUserInfo();
    }
}
