php.ini中的request_order推荐设置,requestorder

今天刚刚安装dede,安装完成由一条错误信息(PHP 5.3 and above) Please set 'request_order' ini value to include C,G and P (recommended: 'CGP') in php.ini

dede中给出了解决的方法,把request_order这个配置选项从默认的

request_order = "GP"

更改为

request_order = "CGP"

问题解决;

关于 request_order 这个配置选项,是php的5.3.x版本中新增加的。

关于他的不安全性可以从以下看出:

$_REQUEST这个超全局变量的值受php.ini中request_order的影响,在最新的php5.3.x系列中,request_order默认值为GP,也就是说默认配置下$_REQUEST只包含$_GET和$_POST而不包括$_COOKIE。通过 COOKIE就可以提交GLOBALS变量。
从而绕过了大多开源程序中的全局变量防御。因此要将次选项更改为 request_order = "CGP"
