Php 为什么我从PayPal'；什么是IPN？

在我的网站上做了一个简单的web事务后，我的IPN处理程序收到的不仅仅是一个预期的“完成”点击，而是两个点击。每个都有不同的数据。第一个是这样的：

stdClass Object
(
[transaction] => Array
    (
        [0] => stdClass Object
            (
                [invoiceId] => PVIFmMOZTm2xkjbs

                [receiver] => me@gmail.com
                [is_primary_receiver] => false
                [id] => 08B29244UF9480324
                [status] => Completed
                [paymentType] => GOODS
                [status_for_sender_txn] => Completed
                [pending_reason] => NONE
                [amount] => GBP 50.00
            )

    )

第二个是这样的：

我如何理解这些数据？为什么会有两支安打？哪一个是我需要注意的

显示的数组是每个请求的PHP$\u POST数组的直接打印输出。您可以从时间戳中看到，一个IPN比第二个稍早到达

编辑：

我已经了解到，第一个阵列（第一次IPN命中）是您在使用Adaptive Payments API时获得的额外接收

对于大多数用例，我相信这是可以忽略的，因为第二次IPN命中包含了您将需要的所有有用数据

尽管有一个警告是第二个更有用的IPN阵列在第一个阵列之后2分钟出现。第一次IPN点击在付款处理后立即到达，而第二次IPN点击在处理后2分钟才到达。。。不知道这是为什么

谢谢

我认为问题在于你对打击的最初定义。或者，您可能错误地定义了一个变量，这就是为什么您的“第二个”IPN的时间戳比“第一个”早2分钟；）你的产品是什么？是的，我不知道为什么，这是一个使用自适应支付API和PayPal JS的普通“商品”支付，我收到两个单独的post请求。显示的数组是每个请求的PHP$\u POST数组的直接打印输出。从时间戳可以看出，一个请求比下一个请求早
