错误codeigniter为同一用户生成多个会话
我是该框架的新手。但是，使用codeigniter 3.19和Ion Auth 3创建一个项目，作为身份验证和用户注册的方法。
在我的本地服务器xampp窗口上，它可以完美地为每个用户生成一个会话。但是在我的带有linuxflare的web linux ubuntu 16.04，vestacp中，我每1 sg会生成10个会话，并且不断有数百万个会话记录，并且考虑到我的流量很少，我认为这是为每个用户创建重复会话的错误。
所有字段ip_address中的会话捕获为我提供了服务器的IP。

几个月前，我遇到了类似的问题。
由于您处在cloudflare上，它具有多个出口节点，这些节点需要不断了解您的应用程序是否处于运行状态，因此您可能会受到多项运行状况检查的打击。如果将运行状况检查定向到加载了会话库的站点的一部分，则每次运行状况检查都将创建一个空会话（您可以检查...表中的大多数会话行将具有一个空的data字段）
由于您要自动加载ion auth，并且在其中要加载构造函数中的会话库，因此相加。
有一些解决方法： 您可能会让Cloudflare将其运行状况检查指向站点的不使用会话的某些部分。如果可以的话，那是最简单/最简单的解决方法，并且需要零编码。
如果您无法更改Cloudflare发送支票的位置，则不会丢失所有信息。您可以为运行状况检查所在的特定控制器/方法设置不会自动加载Ion和/或会话库的异常。有关如何执行此操作的很好的指导，可以在这里找到：
Codeigniter: Change autoload libraries for one controller?
如果这也不是一种选择，并且您无法通过这种方式“保护”自己，则可以设置一个简单的管家脚本，该脚本会定期删除空会话。这不是最佳选择，但有帮助
