我遇到了PayPal回拨功能的麻烦,我无法让我的生活完全发挥作用。我已经仔细检查了回调URL路径,这是正确的。当用户登录到paypal时,它始终只返回默认运费。我真的不确定我在这里缺少什么,如果有人可以提供帮助的话。此外,我将回调超时设置为6,但它似乎只需要3-4秒就可以失败并返回默认运费。
我已按照此处的文档https://developer.paypal.com/docs/classic/express-checkout/integration-guide/ECInstantUpdateAPI/将其应用到我的网站。我也确定我也登录了沙箱。
SetExpressCheckout参数:
// SetExpressCheckout
$params = array (
'METHOD' => 'SetExpressCheckout',
'PAYMENTREQUEST_0_PAYMENTACTION' => 'Sale',
'VERSION' => $version, // 124.0
'USER' => $paypal_user,
'PWD' => $paypal_password,
'SIGNATURE' => $signature,
'L_SHIPPINGOPTIONNAME0' => 'Flat',
'L_SHIPPINGOPTIONLABEL0' => 'N/A',
'L_SHIPPINGOPTIONAMOUNT0' => '6.99',
'L_SHIPPINGOPTIONISDEFAULT0' => 'true',
'PAYMENTREQUEST_0_INSURANCEOPTIONSOFFERED' => 'false',
'PAYMENTREQUEST_0_SHIPPINGAMT' => $shipping_default, // 6.99
'PAYMENTREQUEST_0_ITEMAMT' => $cart_total,
'PAYMENTREQUEST_0_AMT' => $cart_total + $shipping_default,
'MAXAMT' => $cart_total + 30, // 30 is the total possible shipping amount
'PAYMENTREQUEST_0_CURRENCYCODE' => $paypal_currency, // AUD
'RETURNURL' => $paypal_return,
'CANCELURL' => $paypal_cancel,
'CALLBACK' => 'HTTP://localhost/moes/php/paypal_callback_php.php',
'CALLBACKTIMEOUT' => 6,
'CALLBACKVERSION' => '61.0',
'ALLOWNOTE' => 1,
'PAYMENTREQUEST_0_INVNUM' => '123' /*$invoice_number*/,
'PAYMENTREQUEST_0_TAXAMT' => $tax, // 0.00
);
// List each product and add to exress check-out array
foreach ($paypal_products as $k => $product){
$params["L_PAYMENTREQUEST_0_NAME$k"] = $product['name'];
$params["L_PAYMENTREQUEST_0_AMT$k"] = number_format($product['price'],2);
$params["L_PAYMENTREQUEST_0_QTY$k"] = $product['qty'];
$params["L_PAYMENTREQUEST_0_NUMBER$k"] = $product['code'];
$params["L_PAYMENTREQUEST_0_DESC$k"] = '1';
/* Optional shipping options to calculate shipping costs on callback
Option weight (L_PAYMENTREQUEST_n_ITEMWEIGHTVALUEm, L_PAYMENTREQUEST_n_ITEMWEITHTUNITm)
Option height (L_PAYMENTREQUEST_n_ITEMHEIGHTVALUEm, L_PAYMENTREQUEST_n_ITEMHEIGHTUNITm)
Option length (L_PAYMENTREQUEST_n_ITEMLENGTHVALUEm, L_PAYMENTREQUEST_n_ITEMLENGTHUNITm)
Option width (L_PAYMENTREQUEST_n_ITEMWIDTHVALUEm, L_PAYMENTREQUEST_n_ITEMWIDTHUNITm)*/
}
回调脚本:
<?php
// Populate variables into local variables
$method = $_POST['METHOD'];
$version = $_POST['CALLBACKVERSION'];
$token = $_POST['TOKEN'];
$currencycode = $_POST['CURRENCYCODE'];
$localecode = $_POST['LOCALECODE'];
$street = $_POST['SHIPTOSTREET'];
$street2 = $_POST['SHIPTOSTREET2'];
$city = $_POST['SHIPTOCITY'];
$state = $_POST['SHIPTOSTATE'];
$country = $_POST['SHIPTOCOUNTRY'];
$zip = $_POST['SHIPTOZIP'];
// Setting shipping rate based on country [Test only]
if ($country == "US"){
echo "METHOD=CallbackResponse&OFFERINSURANCEOPTION=false&L_SHIPPINGOPTIONNAME0=FLat&L_SHIPPINGOPTIONLABEL0=N/A&L_SHIPPINGOPTIONAMOUNT0=10.00&L_TAXAMT0=1.00&L_INSURANCEAMOUNT0=9.00&L_SHIPPINGOPTIONISDEFAULT0=true";
} else {
echo "METHOD=CallbackResponse&OFFERINSURANCEOPTION=false&L_SHIPPINGOPTIONNAME0=FLat&L_SHIPPINGOPTIONLABEL0=N/A&L_SHIPPINGOPTIONAMOUNT0=30.00&L_TAXAMT0=1.00&L_INSURANCEAMOUNT0=9.00&L_SHIPPINGOPTIONISDEFAULT0=true";
}
?>
我猜我在这里遗漏了一些基本的东西,或者我的方式完全是错误的。

我的问题的解决方案是:
