【中文标题】支付成功后无法找回Paypal信息【英文标题】：impossible to retrieve Paypal information after successful payment 【发布时间】：2020-04-29 14:50:37 【问题描述】：

我正在尝试在销售网站上集成贝宝付款。客户部分运作良好，客户付款并且钱在卖方帐户中。允许恢复交易号、金额、客户地址等数据的第二部分不起作用。但我使用的是 Paypal 提供的脚本。

hello, according to the advice of PHPology I set up the return call URL and of course used the PAYPAL script. I went to the history of IPN messages and I have an HTTP 500 error. I think there may be a syntax error in the PAYPAL script they are specialists in this kind of error.

【问题讨论】：

我已经有一段时间没有使用 Paypal，但您是否在 Paypal 中定义了回调 URL？ “下面的脚本不起作用”和“当下面的脚本运行时，这是它在运行时或与 PayPal 通信时遇到的错误”是两种不同类型的信息。您的问题似乎缺少后者。 @PHPology，这个解决方案是调用者，它不使用回调 URL 亲爱的 PHPology 我没有定义返回 URL。 PAYPAL的解释中没有提到。 Preston PHX 当我写它不起作用时，我的意思是它没有通过任何东西，即使在控制台中我也没有显示错误。你好，我设置了回调 URL，当然也使用了 PAYPAL 脚本。我查看了 IPN 消息的历史记录，我遇到了 HTTP 500 错误。我认为 PAYPAL 脚本中可能存在语法错误，他们是此类错误的专家。 【参考方案1】：

我解决了这个问题。 Paypal 提供的脚本由于存在语法错误而无法运行。他们对这些方法的解释非常模糊。最后在做了一些语法和 url 修改后，我的 php IPN paypal IPN 监听器软件工作了。
