支付朋友快递结帐PHP

Question

我一直在使用paypal api进行exprescheckout。 问题：我无法调用L_PAYMENTREQUEST_n_方法。 PAYMENTREQUEST_0_有效。 但我只能将其用于价格或商品价格。 对于描述和数量，我需要使用L_PAYMENTREQUEST_n_方法。

感谢任何帮助

您的要求是这样发出的...

Array
(
    [METHOD] => SetExpressCheckout
    [USER] => paypalap@email.com
    [SIGNATURE] => fhhasHDJKHSAHJAL74327327dbsasahbsdcsadb7434
    [PWD] => passwd1234
    [RETURNURL] => https://localhost/env/paypal/geschafft.php
    [CANCELURL] => https://localhost/env/paypal/cancel.php
    [VERSION] => 93
    [PAYMENTREQUEST_0_AMT] => 18.97
    [PAYMENTREQUEST_0_CURRENCYCODE] => EUR
    [L_PAYMENTREQUEST_0_NAME$k] => Premium
    [L_PAYMENTREQUEST_0_DESC$k] => 
    [L_PAYMENTREQUEST_0_ITEMAMT$k] => 9.96
)

您需要在参数名称周围使用双引号，以便像这样直接在内部使用$ k，因此您需要这样做...

foreach ($paketdata as $k => $paket){
    $params["L_PAYMENTREQUEST_0_NAME$k"] = $paket['name'];
    $params["L_PAYMENTREQUEST_0_DESC$k"] = '';
    $params["L_PAYMENTREQUEST_0_ITEMAMT$k"] = $paket['preis'];
}

然后，这种变化给了我，应该可以了。

Array
(
    [METHOD] => SetExpressCheckout
    [USER] => paypalap@email.com
    [SIGNATURE] => fhhasHDJKHSAHJAL74327327dbsasahbsdcsadb7434
    [PWD] => passwd1234
    [RETURNURL] => https://localhost/env/paypal/geschafft.php
    [CANCELURL] => https://localhost/env/paypal/cancel.php
    [VERSION] => 93
    [PAYMENTREQUEST_0_AMT] => 18.97
    [PAYMENTREQUEST_0_CURRENCYCODE] => EUR
    [L_PAYMENTREQUEST_0_NAME0] => Premium
    [L_PAYMENTREQUEST_0_DESC0] => 
    [L_PAYMENTREQUEST_0_ITEMAMT0] => 9.96
)

但是，另一方面，您不想在返回中使用localhost并取消URL。 PayPal的服务器是重定向到该URL的服务器，因此当时的localhost是他们自己的服务器，这当然不会做您想要的事情。

您需要使用公用IP地址或设置一个解析为您可以使用的IP的域。

实际上，这很有趣，我只是在这里尝试在本地主机的前面使用http：//，而Stack不会因为这个原因而让我发布带有链接的链接……它们会链接到自己。
