Question

我刚刚在错误日志中注意到，每当我向PayPal API发出请求时（使用php + curl），一些返回的标头都出现在我的apache错误日志中（不是访问日志）。据我所知，这个特殊的请求从一开始就已经填满了我的日志（几个月了），但我今天才第一次注意到它。现在我知道这不是一个大问题，但是我很乐意摆脱它，因为这样可以更容易地解决其他问题。

首先，这是错误日志：

即使我使用他们的示例代码发出请求，错误仍会显示出来。我甚至关闭了SSL_VERIFYPEER和SSL_VERIFYHOST curl选项，希望ssl（仍然有效）导致问题。我尝试过其他curl请求（不是通过ssl），但它们没有显示在错误日志中。

任何人都可以帮我查明问题吗？

Answer 1

尝试使用此cURL选项：

curl_setopt($ch, CURLOPT_VERBOSE,0);

Answer 2

您使用的是CURLOPT_CERTINFO吗？它如此描述：

TRUE在安全转移时向STDERR输出SSL认证信息。

同时检查CURLOPT_VERBOSE，必须启用CURLOPT_CERTINFO才能在较新的PHP版本中使用。

标题出现在apache错误日志（curl和paypal）
