paypal快速整合混乱和paypal提供的文件不工作

Question

我使用paypal集成向导来创建我需要将paypal集成到自定义购物车中的文件,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,并收到此错误

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？

这是我加载的页面.目前我没有将这些页面附加到商业网站,我只测试paypal提供的文件,看看它是否在进行任何集成之前有效.

require_once ("paypalfunctions.php");

//'------------------------------------
//' The paymentAmount is the total value of

$paymentAmount = "10.45";

$resArray = CallShortcutExpressCheckout ($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;
}

Detailed Error Message:  Security header is not valid

这是什么意思？

这意味着您的安全标头无效.
