使用Paypal的IPN的php的cURL错误：[60]

可能重复：

我正在使用cpanel管理一个网站。我已经设置了一个ipn.php文件和一个ipnlistener.php文件，以便从我的网站上收听来自Paypal的ipn。我还设置了一个ipn_errors.log文件来记录错误。错误日志显示以下错误：cURL error:[60]设置证书验证位置时出错： CAfile:/home/wwwplrma/public\u html/cert/api\u cert\u chain.crt 卡帕斯：没有

我在public\u html目录中没有看到任何这样的证书。文件的权限是否有问题，或者此错误是否与其他内容有关？ipn.php和ipnlistener.php的权限设置为644，ipn_errors.log的权限设置为775，提前感谢

我的代码如下：

ipn_errors.log：

既然这有助于您，我将添加它作为答案；希望它也能帮助其他人，但不知何故我对此表示怀疑：）

ipnlistener.php
中的代码使用
CURLOPT_CAINFO
指定证书链的路径，因此必须存在于服务器上：

/home/wwwplrma/public_html/cert/api_cert_chain.crt

@谢谢你的回复！我已编辑了我的问题以区分它。：）类“IpnListener”未找到-证书不是您的主要问题（是否？）。事实上，该错误是昨天出现的，因为IpnListener.php文件有编码错误。这个问题昨天就解决了，现在已经不存在了。您可以使用时间戳查看较新的错误。最新的错误就在最下面。那就从你的问题中消除噪音吧，因为这与你的具体问题无关了。此外，我建议您将错误消息（现在算在内的）放在示例代码上方。完成编辑，感谢您帮助我将问题发布好。我是新来的。：）
