Question

嗨，我很擅长编码并尽力摆脱我的菜鸟状态我在Windows 7上开始使用apache 2.4，mysql，php 5.6 （我想人们称之为WAMP，但直到昨天我才知道WAMP的存在）

反正，我目前正在自己的网站上工作，最终将导致用户付款。使用，paypal，付款（checkoutpage.php已设置且没有问题），我需要更新我的mysql数据库。所以，在过去的10天里，我一直在研究ipn_listener.php文件，现在我理解了这个的基本流程（我认为）。

但是我一直收到如下错误。错误设置证书验证位置： CAfile：C：绝对\ path \ to \ cacert.pem CApath：无

这让我疯狂我已经用Google搜索了一个多星期了，但仍然无法解决这个问题。我知道我错过了一些东西，但我尝试了很多东西，比如... 安装ngrok（仍然这样做）安装openssl 1.0.1l 安装curl（php支持这个。从phpinfo（）检查）

这是我到目前为止提出的听众脚本

证书验证失败了。您可以通过将CURLOPT_SSL_VERIFYPEER更改为false来绕过验证：curl_setopt（$ ch，CURLOPT_SSL_VERIFYPEER，0）。
