【问题描述】：

我在 Payapl IPN 模拟器中使用以下代码，但不断收到 ssl 连接错误

我是否需要在主机上安装 ssl 才能使用 Paypal Ipn？

我已经联系了我的托管公司，他们说他们不知道为什么我会收到这个错误，他们建议我可能需要购买 ssl 但我不确定这是不是这个原因

【问题讨论】：

也有同样的问题。

【参考方案1】：

您的 paypal 网址是否正确，请检查一次

检查：放 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 并删除 curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);并测试它是否收到任何错误消息

【讨论】：

感谢您的回复，我做了您的建议，但没有运气仍然收到相同的错误消息，并且 paypal url 是正确的，我正在使用沙箱 sandbox.paypal.com/cgi-bin/webscr

当然，这是日志文件中的错误消息：[2016-02-16 04:29 America/Chicago] Can't connect to PayPal to validate IPN message: SSL connect error

等待我将尝试执行您的代码并检查删除此代码并尝试 curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);

您是否尝试过删除此代码：curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);

是的，我现在刚刚尝试过，仍然收到相同的错误消息
