php - 无法将我的 PayPal IPN 脚本从 http 1.0 转换为 1.1

Question

我的脚本目前已经上线，我有一个有问题的沙箱来测试我的修改，这激怒了我的一些客户。我最好在现场测试。

PayPal 发了一封电子邮件警告我们，并不断提醒我跳到 1.1，但自 6 月以来，我一直运气不好，尝试了各种组合并咨询了各种平台以寻求建议。

下面是我当前的 PayPal.php 代码，它链接到我的网站所需的许多类。

我尝试了很多编码组合，从注释行中可以明显看出这一点。

他们似乎无法工作，我的选择已经用完了。

有好心人能解决这个问题吗？或者告诉我出了什么问题？

IPN 总是回复我无效的响应或错误，但在 http 1.0 中一切都很好而且花花公子......

不知何故，直接修剪结果(而不是在比较之前)对我有用:

$res = fgets ($fp, 1024);$res = trim($res);

祝你好运
