PHP Fatal error: Uncaught InvalidArgumentException: Malformed UTF-8 characters, possibly incorrectly encoded in D:\phpstudy_pro\WWW\www.demo.com\vendor\topthink\framework\src\think\response\Json.php:50这个错的原因是服务器mysql版本是5.6，而我这台机子的版本是5.7，这样导致字符集问题？
我看了下两个版本的字符集都是utf8的，问题出在哪呢？
mysql> show variables like 'character%';

最近换了太开发机子，登录时报服务器500错误，经测试Session::set(config("admin.admin_session_name"), ['id'=>1]);报这个错，如果换成Session::set('username',['id'=>1]);这样写却不报错
AdminUser::where("username" ,$username) ->findOrempty();这样写也会报这个错误
查找了半天找不到原因，由于Session::set(config("admin.admin_session_name"), ['id'=>1]);这个似乎没有涉及到sql数据呀，所以迟迟没找到是数据库版本的原因
