php - 运费总额和即时更新 API 的 PayPal 错误

转载作者：太空宇宙更新时间：2023-11-03 16:11:47

我正在尝试调用 ExpressCheckout 并执行即时更新 API，但无论我做什么，它似乎都会返回一个无效的总运费错误。我知道在实时运行时需要使用 SSL，但是我正在尝试针对沙箱进行测试，但仍然出现这些错误。

我的简单 HTML 测试页:

        <input type=submit name=METHOD value=SetExpressCheckout> 
    </form>
</body>
</html>

托管在我的服务器上的我的 callback.php 脚本:

<?php
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req = "&$key=$value";
}

//Build string
$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'];

//If PayPal acocunt has US address
if ($country=="US") {
    echo "METHOD=CallbackResponse&L_SHIPPINGOPTIONNAME0=Ground&L_SHIPPINGOPTIONLABEL0=5 to 7 Days&L_SHIPPINGOPTIONAMOUNT0=10.00&L_SHIPPINGOPTIONISDEFAULT0=true";
    }   

//If PayPal account has a non-US address    
else {
    echo "METHOD=CallbackResponse&L_SHIPPINGOPTIONNAME0=Next Day Air&L_SHIPPINGOPTIONLABEL0=7 to 14 Days&L_SHIPPINGOPTIONAMOUNT0=20.00&L_SHIPPINGOPTIONISDEFAULT0=true";
    }
?>

我已经从代码中删除了一些敏感信息，并将所有运输值更改了 100 次，所以如果有一些愚蠢的错误，请原谅。任何帮助将不胜感激，谢谢!

最佳答案

根据 Paypal's Developer Guide (第 58 页)声称 CURRENCYCODE 是必需的。尽管在我的测试中，情况似乎并非如此。但值得一试。

此外，对您的值进行 url 编码也可能会发生这种情况...因此请将您的空格变成 +s。

我已将其用作有效的测试响应:L_INSURANCEAMOUNT1=1.35&L_SHIPPINGOPTIONISDEFAULT2=false&L_SHIPPINGOPTIONNAME0=1%3A+&L_SHIPPINGOPTIONNAME1=2%3A+&L_SHIPPINGOPTIONLABEL0=asdf&L_SHIPPINGOPTIONLABEL1=UPS+Express+2+Days&OFFERINSURANCEOPTION=true& CURRENCYCODE=USD&L_INSURANCEAMOUNT2=1.28&L_TAXAMT0=2.20&L_SHIPPINGOPTIONAMOUNT1=10.00&L_SHIPPINGOPTIONAMOUNT0=20.00&L_SHIPPINGOPTIONAMOUNT2=9.99&L_SHIPPINGOPTIONAMOUNT1=9.99&L_SHIPPINGOPTIONAMOUNT1 =true&L_SHIPPINGOPTIONISDEFAULT0=false&L_SHIPPINGOPTIONNAME2=3%3A+&L_SHIPPINGOPTIONLABEL2=UPS+Ground+2+to+7+Days&L_TAXAMT1=2.00&METHOD=CallbackResponse&L_INSURANCEAMOUNT0=1.35&L_TAXAMT2=1.99
