Question

我正在尝试将PayPal IPN集成到我的应用中。我正处于测试的第一阶段。我已复制/粘贴此代码： https://github.com/paypal/ipn-code-samples/blob/master/paypal_ipn.php

然后，在这里使用IPN测试器： https://developer.paypal.com/developer/ipnSimulator

我发送了一个IPN。这将返回消息“我们很抱歉，但是出现HTTP错误。请再试一次。”如果我检查检查员，在网络下有400错误。

日志文件的输出如下：

我已检查过服务器上的错误，但没有。我也尝试修改代码以考虑以下注释：

// CONFIG: Please download 'cacert.pem' from "http://curl.haxx.se/docs/caextract.html" and set the directory path
// of the certificate as shown below. Ensure the file is readable by the webserver.
// This is mandatory for some environments.
//$cert = __DIR__ . "./cacert.pem";
//curl_setopt($ch, CURLOPT_CAINFO, $cert);

我不知道还能检查什么。

Answer 1

我按照链接建议中的表单构建，这导致了php代码工作正常的额外证据。经过几次跟踪过程并跟踪IPN模拟器网络请求后，我决定尝试通过http而不是https连接到我的网站。通过https连接是导致400错误的触发器。通过http连接并且不会产生错误。

使用PHP的PayPal IPN通过IPN Tester和Sandbox返回HTTP 400
