What's this about?

This sample code features a service wrapping some logic for google OAuth rest services.

Usage:

Import and inject it in your class:

    import { GoogleOauthService } from '../google-oauth.service';
    ...
    
    constructor(private googleAuth: GoogleOauthService) { }

It has 3 public methods: initProcess(), getLoginResponse() and getUserProfile().

Iniating Login Flow:

    _baseUrl: string = 'https://accounts.google.com/o/oauth2/v2/auth';
      _parameters = {
    	  "client_id": "[yours]",
    	  "redirect_uri": "[yours]",
    	  "response_type": "token",
    	  "scope": "https://www.googleapis.com",
    	  "state": ""
      };
     public login(){
    	  this.googleAuth.initProcess(this._baseUrl, this._parameters);
      }

Parameters object most conform to googleOAutParams:

    interface googleOAutParams {
    	client_id: string;
    	redirect_uri: string;
    	response_type: string;
    	scope: string;
    	state?: string;
    }

Checking token's validity and fetching user's name:

    this.googleAuth.getLoginResponse(res => {
            console.log(res, "respuesta");
            if (!res.error) {
                this._user = res;
                this.googleAuth.getUserProfile(this._user.access_token).then(prof => {
                    this._profile = prof;
                }).catch(err => { });
            } else {
                console.log(res.error);
                this.router.navigate(['/login']);
            }
        }, err => {
            console.log(err);
        });

The road ahead

• Add Logout Functionality
• Implement FaceBook Login
• Wrap FB and Google Login so they conform to a single Interface (Adapters and Strategies pattern)
• Add routes Guard in order to check if user is Logged in when navigating to a view
