Download the PHP package lcmaquino/youtubechannel without Composer

Introduction

YouTubeChannel adds to Laravel the service provider for OAuth 2.0 authentication with YouTube Google account.

It was created based on GoogleOAuth2 that is a Laravel package for OAuth 2.0 authentication with Google account.

Features

• The same features of GoogleOAuth2;
• Check if an user is subscribed on a given YouTube channel;
• Get some YouTube channel statistics: subscription count, views count and videos count.

For more information about Google OAuth 2.0, please see https://developers.google.com/identity/protocols/oauth2/web-server

Installation

Laravel should automatically include Lcmaquino\YouTubeChannel\YouTubeChannelProvider as a service provider and include YouTubeChannel as an alias for Lcmaquino\YouTubeChannel\Facades\YouTubeChannel::class.

It can be done manually editing config/app.php to look like:

Configuration

Before using YouTubeChannel, you need to set up an OAuth 2.0 client ID. The OAuth 2.0 client will provide a client id, a client secret, and a redirect uri for your application. These parameters and the youtube channel id should be placed in your .env Laravel configuration file.

It will be loaded by your application when reading the file config/googleoauth2.php:

Routing

Create two routes in routes/web.php:

Create app/Http/Controllers/Auth/LoginController.php and edit like this:

When you hit the route login/youtube it will redirect your request to Google authentication page. Google authentication will ask user for permission and then hit your callback route login/youtube/callback.

YouTubeChannel comes with a YouTubeChannel facade. So you could edit app/Http/Controllers/Auth/LoginController.php like this:

Optional Parameters

To include any optional OAuth 2.0 parameters in the request, call the with method with an associative array:

Access Scopes

The scopes are used by Google to limit your application access to the user account data. Use the scopes method to set your scopes. The defaults are openid, email and https://www.googleapis.com/auth/youtube.readonly.

Stateless Authentication

The stateless method disable session state verification.

Retrieving User Details

Once you have an authenticated $user, you can get more details about the user:

Retrieving User Details From A Token

You can retrieve user details from a valid access $token using the getUserFromToken method:

Refreshing token

The access token expires periodically. So you need to get a new one. You can get this using the refreshUserToken method:

You should pay attetion to keep the user $refresh_token on your application. If you lose it, then you can't get a new access token. In that case, the user has to log in again when the current access token expires.

You will notice that refresh token is not always provided on Google authentication. You can force Google to do so using the with method (see Optional Parameters):

Revoking token

If you need to invalidate the access token and the refresh token, you can revoke them using the revokeToken method:

Tips

• You can use a valid access token or refresh token as $token.
• Remeber to revoke the token when the user decides to sign out/remove their data from your application.
• Keep in mind that the user always can revoke their token on https://myaccount.google.com/permissions.
