CodeIgniter会话cookie域 [英] CodeIgniter session cookie domain

问题描述

在下面的Cookie设置中，系统会为整个网域设置Cookie。例如，如果我在 http://subdomain.domain.com 上，则会为subdomain.domain.com设置Cookie（如果我位于） domain.com将为domain.com设置cookie。

It appears with the following cookie settings below, that cookies are set for the entire domain. For example if I was on http://subdomain.domain.com the cookie would be set for subdomain.domain.com if I was on domain.com the cookie would be set for domain.com.

如果为subdomain.domain.com设置了cookie，则意味着subdomain2.domain.com无法访问来自subdomain.domain.com的Cookie？

If the cookie is set for subdomain.domain.com that does that mean subdomain2.domain.com cannot access a cookie from subdomain.domain.com?

$config['cookie_prefix']    = "";
$config['cookie_domain']    = "";
$config['cookie_path']      = "/";

推荐答案

特定于域的Cookie只能在该域上访问。使用.domain.com作为您的Cookie网域，即可在所有子网域和主网域中使用。

Domain specific cookies are only accesible on that domain. Use ".domain.com" as your cookie domain to be able to use it across all subdomains and main domain.
