config/services.php

    'wechat_service_account' => [
        'client_id' => env('WECHAT_SERVICE_ACCOUNT_APP_ID'),
        'client_secret' => env('WECHAT_SERVICE_ACCOUNT_APP_SECRET'),
        'redirect' => env('WECHAT_SERVICE_ACCOUNT_CALLBACK_URL'),
        'scopes' => 'snsapi_base',
    ],

    public function redirectToProvider($provider)
    {
        return Socialite::driver($provider)
            ->scopes(config("services.{$provider}.scopes"))
            ->redirect();
    }
