Php 在Socialize laravel 5中发送和检索自定义字段

如何使用此方法在

RedirectToProvider

方法的socialize laravel中发送自定义字段：

if ($social == 'facebook') {
    return Socialize::with($social)->fields([
                'first_name', 'last_name', 'email', 'gender', 'birthday'
            ])->scopes([
                'email', 'user_birthday'
            ])->redirect();
}

假设我想发送网络\u id=>9

那么，在我获取用户信息的handler方法中如何获取它呢

$user = Socialize::with('facebook')->user();

使用

然后从$user数组中检索项，如下所示

$user['email']

我发现使用Socialist获取参数的唯一方法是将其存储在会话中

public function redirectToFacebookProvider()
{
    // save anything you will need later, for example an url to come back to
    Session::put('url.intended', URL::previous());

    return Socialite::driver('facebook')->redirect(); 
}

public function handleFacebookProviderCallback()
{
    // handling....

    $url = Session::get('url.intended', url('/'));
    Session::forget('url.intended');

    return redirect($url);
}

我得到了这个答案

public function redirectToFacebookProvider()
{
    // save anything you will need later, for example an url to come back to
    Session::put('url.intended', URL::previous());

    return Socialite::driver('facebook')->redirect(); 
}

public function handleFacebookProviderCallback()
{
    // handling....

    $url = Session::get('url.intended', url('/'));
    Session::forget('url.intended');

    return redirect($url);
}
