我使用 paypal 集成向导创建了将 paypal 集成到自定义购物车中所需的文件，并在 paypalfunctions.php 页面中添加了 api 凭据。我加载了向导提供的 expresscheckout.php 文件，但出现了这个错误

SetExpressCheckout API call failed. Detailed Error Message: 
Security header is not validShort Error Message: Security 
errorError Code: 10002Error Severity Code: Error

这是什么意思？

这是我只加载的页面。目前我还没有将这些页面附加到商业网站，我只是在进行任何集成之前测试 paypal 提供的文件以查看它是否有效。

require_once ("paypalfunctions.php");
// ==================================
// PayPal Express Checkout Module
// ==================================

//'------------------------------------
//' The paymentAmount is the total value of 
//' the shopping cart, that was set 
//' earlier in a session variable

$paymentAmount = "10.45";

//'------------------------------------
//' The currencyCodeType and paymentType

$currencyCodeType = "USD";
$paymentType = "Sale";

$cancelURL = "http://www.mysite.com/cancelOrder.php";

//'------------------------------------
//' Calls the SetExpressCheckout API call

$resArray = CallShortcutExpressCheckout ($paymentAmount, $currencyCodeType, $paymentType, $returnURL, $cancelURL);
$ack = strtoupper($resArray["ACK"]);
if($ack=="SUCCESS" || $ack=="SUCCESSWITHWARNING")
{
    RedirectToPayPal ( $resArray["TOKEN"] );
} 
else  
{
    //Display a user friendly Error on the page using any of the following error information returned by PayPal
    $ErrorCode = urldecode($resArray["L_ERRORCODE0"]);
    $ErrorShortMsg = urldecode($resArray["L_SHORTMESSAGE0"]);
    $ErrorLongMsg = urldecode($resArray["L_LONGMESSAGE0"]);
    $ErrorSeverityCode = urldecode($resArray["L_SEVERITYCODE0"]);

    echo "SetExpressCheckout API call failed. ";
    echo "Detailed Error Message: " . $ErrorLongMsg;
    echo "Short Error Message: " . $ErrorShortMsg;
    echo "Error Code: " . $ErrorCode;
    echo "Error Severity Code: " . $ErrorSeverityCode;
}

最佳答案

Detailed Error Message:  Security header is not valid

what does it mean?

这意味着您的安全 header 无效。
