PayPal IPN 沙盒不工作，但模拟器可以

Posted 2023-02-22

技术标签:

【中文标题】PayPal IPN 沙盒不工作，但模拟器可以【英文标题】：PayPal IPN Sandbox not working but simulator does 【发布时间】：2013-12-06 00:58:39 【问题描述】：

更新 #1： 我找到了问题，当我使用模拟器时，$res 变量的字符串应该是“已验证”，因为它是从标题中分解出来的当我使用沙箱时，情况似乎并非如此，标题保留在该变量中。我能做什么？

我已使用 PayPal 提供的 IPN php 代码在我的网站上进行付款（取决于您选择的产品）。如果我使用 IPN 模拟器，它可以正常工作，并且可以正常发布日志，但是当使用沙盒帐户时（我在我的卖家帐户上启用了 IPN），它不会在 VERIFIED 一词之后记录，请参见此处，第一个是沙盒测试，另一个是模拟器测试

我用于 IPN 侦听器的代码是这样的：

    define("DEBUG", 1);

    // Set to 0 once you're ready to go live
    define("USE_SANDBOX", 1);

    define("LOG_FILE", "./ipn.log");

    // Read POST data
    // reading posted data directly from $_POST causes serialization
    // issues with array data in POST. Reading raw POST data from input stream instead.
    $raw_post_data = file_get_contents('php://input');

我假设我的表单有问题？我按照PayPal javascript buttons的建议添加了所有内容

这是我的不购买按钮表单 HTML 代码：

【问题讨论】：

【参考方案1】：

如果调试已打开，您只会拆分标题。也许这就是问题所在。我不确定你为什么要费心拉出标题，因为响应将是完全相同的加上 VERIFIED （或不）。我只是匹配整个响应。

if (preg_match("!(VERIFIED)\s*\Z!",$res))
  /*payment verified, handle */  
else
  /* boo fake payment OR paypal is having problems */

【讨论】：

谢谢，成功了。不过那是我从 PayPal 得到的脚本示例，我猜他们没有用沙盒测试它？我不知道。我也基于示例脚本......从 4 年多前开始 :) 也许他们已经更新了它，很糟糕。沙盒是对“实时”IPN 工作方式的现场测试。如果它不能在沙盒中工作，那么它就不能用于实时支付。是的，该脚本已针对沙盒进行了测试。您能否将 ipn.log 的内容连同您的问题一起包含在内？只有当我在 Sandbox 中直接使用信用卡付款时才会遇到此错误。响应将包含“HTTP response of validation request: HTTP/1.1 100 Continue HTTP/1.1 200 OK”而不是 HTTP/1.1 200 Ok only..

以上是关于PayPal IPN 沙盒不工作，但模拟器可以的主要内容，如果未能解决你的问题，请参考以下文章

Paypal 沙盒 IPN 模拟器 - 502 Bad Gateway

从 PayPal 的沙盒 IPN 获得无效响应

（Laravel）无法从PayPal IPN获得响应，但模拟的响应返回已经过验证

Paypal IPN 在沙盒 ipn sinulator 中有效，但在交易中无效

PayPal IPN 模拟器测试产生一个空的 curl 结果。在现场工作正常

测试 IPN 不应该从我的 Paypal 沙盒帐户中取钱吗？
