php会话随机丢失，无法理解为什么
2022-08-30 22:20:26
我付钱给一个程序员制作一个购物篮脚本来使用Spreadshirt API。一切都很完美，除了篮子一直在清空自己。我认为会话在某个时候丢失了，因此脚本创建了另一个.BasketId
我试图找出它是否发生了一个具体的原因，没有任何成功......我无法重现该错误。它只是随机发生，没有任何理由。关闭浏览器，重置apache甚至整个Web服务器都不会引起会话丢失。
我有两个不同的脚本在同一个域上使用cookie，它们没有任何问题（一个是管理员登录会话的cookie，另一个是保存用户在商店上上次查看的文章）
我尝试了在谷歌上找到的所有解决方案，但没有任何成功：编辑，通过php强制ini设置，尝试了方法，...php.inihtaccess
这是我的phpinfo的“会话”部分：http://gyazo.com/168e2144ddd9ee368a05754dfd463021

该脚本还有另外2个部分：一个用于将示例T恤添加到篮子中的表单和一个用于调用ajax的脚本。如果需要，可以发布它，但没有会话处理的东西。(example.php)(shop-controller.js)
更新 - 也许问题与会话无关。BasketId 丢失，但 PHPSESSID 在浏览器 Cookie 中保持不变。
在过去的3天里，我做了以下测试（用不同的计算机和浏览器进行测试）：
清空浏览器 Cookie，然后在下午开始新会话
将1个项目添加到购物篮，我写下篮子Id并检查浏览器cookie以写下PHPSESSID
通常总是在午夜左右，篮子自己清空
PHPSESSID在我的浏览器cookie中保持不变，即使在购物篮清空之后也是如此
但是，BASKETID是不一样的，下午使用的那个丢失了，一个新的被再生了。
