It is kinda hard to integrate oauth2 with loopback

[ghost]

Issue

I have working model of passport with google and github. Now I want to use oauth2 server to authorize external website with my login model.

Expected Working Model

1. Collect User logins with passport login strategy.
2. Oauth2 server will use the login details to get user information and than it will authorize external oauth2 request.
3. the /oauth/authorize and /oauth/token should be working with that

server files

/server/boot/oauth2-server.js

'use strict';

var oauth2 = require('loopback-component-oauth2');
module.exports = function(app) {
  var options = {
    dataSource: app.dataSources.db, // Data source for oAuth2 metadata persistence
    loginPage: '/login', // The login page url
    loginPath: '/login', // The login form processing url
    loginFailPage: '/loginfailed',
    resourceServer: true,
    authorizationServer: true,
    authorizePath: '/oauth/authorize',
    tokenPath: '/oauth/token',
    supportedGrantTypes: [
      'implicit',
      'jwt',
      'clientCredentials',
      'authorizationCode',
      'refreshToken',
      'resourceOwnerPasswordCredentials',
    ],
  };
  oauth2.oAuth2Provider(
    app, // The app instance
    options // The options
  );
};

/server/boot/passport-auth.js

'use strict';
var loopback = require('loopback');
var cookieParser = require('cookie-parser');
var session = require('express-session');
var bodyParser = require('body-parser');
var loopbackPassport = require('loopback-component-passport');
var flash = require('express-flash');
module.exports = function(app) {
  var PassportConfigurator = loopbackPassport.PassportConfigurator;
  var passportConfigurator = new PassportConfigurator(app);
  var config = {};
  try {
    config = require('../providers.json');
  } catch (err) {
    console.trace(err);
    process.exit(1); // fatal
  }

  // to support JSON-encoded bodies
  app.middleware('parse', bodyParser.json());
  // to support URL-encoded bodies
  app.middleware('parse', bodyParser.urlencoded({
    extended: true,
  }));

  // The access token is only available after boot
  app.middleware('auth', loopback.token({
    model: app.models.accessToken,
  }));

  app.middleware('session:before', cookieParser('mysecret'));
  app.middleware('session', session({
    secret: 'kitty',
    saveUninitialized: true,
    resave: true,
  }));
  passportConfigurator.init();

  // We need flash messages to see passport errors
  app.use(flash());

  passportConfigurator.setupModels({
    userModel: app.models.user,
    userIdentityModel: app.models.userIdentity,
    userCredentialModel: app.models.userCredential,
  });
  for (var s in config) {
    var c = config[s];
    c.session = c.session !== false;
    passportConfigurator.configureProvider(s, c);
  }
};

Errors

1. undefined LogIn

   this._passport.instance._sm.logIn(this, user, function(err) {
                               ^
   TypeError: Cannot read property 'logIn' of undefined

2. /oauth/authorize, show the username and password fields when unregistered client id passed

@dhmlau how to run the "loopback-component-oauth2" with below code repository

https://github.com/strongloop/loopback-component-oauth2.git

@samarmeena

Did you ever get this working?

Which loopback version are you using?

I want to achieve the same and I can't figure out how to go about it. Kindly help if you have ideas.

Thanks

@Kabangi Use new loopback 4,But you have to implement your own oauth2 system, that's what I'm currently working on.

@samarmeena Thanks

Yes loopback4 is really awesome. I will implement the same.
