In today's increasingly developing social network era, social login has become a standard feature of more and more websites. It not only facilitates users to log in quickly, but also helps the website increase user traffic and social interaction. Although it is not difficult to implement social login yourself, using ready-made social login components can save time and effort. In PHP development, Laravel Socialite is an easy-to-use social login component. Let's take a look at how to use it to implement social login.
1. Install Laravel Socialite
First we need to install the Socialite package in the Laravel application, use the following command:
composer require laravel/socialite
After the installation is complete, add the Socialite service provider in the config/app.php
file:
'providers' => [ // Other service providers... LaravelSocialiteSocialiteServiceProvider::class, ]
Then in the config/app.php
file Add the Socialite facade alias:
'aliases' => [ // Other aliases... 'Socialite' => LaravelSocialiteFacadesSocialite::class, ]
In this way, we successfully installed the Socialite component.
2. Create a social login application
Socialite can support many different social login applications, and we need to create an application for each application. The following uses GitHub as an example to demonstrate creating a new OAuth application on GitHub.

3. Implement social login
<a href="{{ url('/auth/github') }}">使用GitHub登录</a>
routes/web.php
file and add the following route definition: Route::get('auth/github', 'AuthLoginController@redirectToProvider'); Route::get('auth/github/callback', 'AuthLoginController@handleProviderCallback');
Here we are asked to redirect the user to the GitHub authentication service via redirectToProvider
and Complete the login authentication there. When the authentication is successful, the GitHub authentication service will redirect to the specified callback URL auth/github/callback
, and pass the successfully authenticated user information in the Session through this URL.
redirectToProvider
function. Open the app/Http/Controllers/Auth/LoginController.php
file and add the following implementation: namespace AppHttpControllersAuth; use IlluminateHttpRequest; use AppHttpControllersController; use Socialite; class LoginController extends Controller { // ... public function redirectToProvider() { return Socialite::driver('github')->redirect(); } // ... }
We call in
Socialite driver()
method to obtain an instance of the GitHub authentication driver, and use the redirect()
method to redirect the user to the login authentication service.
handleProviderCallback
method. Open the app/Http/Controllers/Auth/LoginController.php
file and add the following method: // ... public function handleProviderCallback() { try { $user = Socialite::driver('github')->user(); } catch (Exception $e) { return redirect('/login'); } // 验证用户信息并完成登录,代码省略 // ... } // ...
We use user from
Socialite ()
method obtains the user information returned by the GitHub authentication service. If there are any errors during the authentication process, we will redirect the user to the application's login page. If authentication is successful, the information in the $user
object can be used to authenticate the user and complete the login operation.
4. Summary
At this point, we have completed the process of using Laravel Socialite to implement GitHub social login. Through simple configuration and some necessary code, we can easily implement multiple social login methods, adding some small but useful features to the application, which are recommended for use in actual projects.
