上几年班你就会知道，除非是bat级别大公司会去考虑php效率，基本人家也是用自己的框架，几千万pv的公司更多考虑的是nginx和mysql的压力，网站分布式，全站静态化或者局部静态化，利用缓存cdn等等，压力都在mysql和nginx上。解决php负载就是多加一台服务器就好了。
$oauthUser = \Socialite::with('weibo')
打出 $oauthUser 这个对象

$oauthUser = \Socialite::with('weibo')->user();
dd($oauthUser);
var_dump($oauthUser->getId());
var_dump($oauthUser->getNickname());
var_dump($oauthUser->getName());
var_dump($oauthUser->getEmail());
var_dump($oauthUser->getAvatar());
}可以登陆微博跳转，可以正常输出123，但是返回500错误....
