执行此方法后,当我传递到另一个页面时,它会显示此错误

502坏网关

服务器返回了无效或不完整的响应

我做错了什么


会话库是自动加载的,我只是传递给这个方法,没有必要提交

您只是将局部变量和插入放入mysql数据库。从未接触过调用HTTP(客户端)或接受HTTP(服务器)的对象

唯一似乎与HTTP有关的是调用名为redirect的本地函数。 问题可能就在那里

502当到后端服务器的本地HTTP传递失败时,反向代理通常会返回坏网关。
尝试注释掉redirect(“/”),看看会发生什么

知道它为什么进行HTTP调用吗?面临一个非常类似的问题,并且没有发现任何其他关于任何人看到相同问题的信息。我猜这与重定向功能有关,而不是存储会话数据。我也遇到了502坏网关问题。我把范围缩小到它与cart library有关系的程度。你找到解决这个问题的办法了吗?
