Php 无法跨域和子域共享会话

我有一个Laravel应用程序，我希望论坛部分有自己的子域，并允许用户在访问主站点时保持登录状态。这是我的config/session.php文件

伙计们，我想出来了

当我在.env中更改会话驱动程序时，我在Chrome的匿名模式下对其进行了测试

我在正常模式下测试了它，并且跨域加载了会话

基本上，由于Cookie不能跨域共享，所以您必须使用数据库驱动程序。

您是否尝试过在没有前导点的情况下设置域？默认的session.php行是
'domain'=>env（'session\u domain'，null），
，并在
文件中设置
session\u domain=intransportal.test
。env
文件应可用于设置cookie域我按照您的建议设置cookie域，但不带前导点。我在登录后访问了我的子域，但会话仍然没有通过。我做了一些研究，显然你不能在一个域和子域之间共享会话，这是真的吗？这很奇怪-我还有一个Laravel站点，它运行在多个子域之间，并且能够在它们之间维护会话（我在响应之前尝试过！），只需在env文件中设置
session\u domain
，我正在使用Homestead，不是我的生产服务器，如果那个帮助我刚刚注意到我的.env文件的SESSION\u驱动程序值没有设置为database，所以我更改了它。现在cookie在两个域上都不起作用。我得仔细看看。你有没有试过在没有前导点的情况下设置你的域名？默认的session.php行是
