哪种PAYPAL服务更适合网站的在线交易？

标签： paypal transactions currency

我正在开发一个网站，用户必须付费才能使用某些服务。所以我知道PayPal是我可以使用的服务。用户可以使用借记卡，信用卡，PayPal帐户等付款。我知道可以使用PayPal按钮。但在我的网站上，我想给用户一个选项来添加他们选择的数量。用户可以支付5美元或50,000美元或他们想要的任何东西。我不知道我是否可以使用PayPal按钮。

简而言之，用户将以表格形式输入金额。提交表单后，它会将用户重定向到PayPal网站，在那里他们可以支付金额。作为回报，我想确保他们付了多少钱，交易成功与否等来自PayPal，所以我可以在数据库中存储细节，如果交易成功，用户将获得账户余额。

所以我想知道的是PayPal对我来说哪种服务更好？

与PayPal按钮或PayPal网关或PayPal流量网关一样？

我在我的网站上完成了这个。我会为它发布一些代码。基本上你创建了一个不隐藏的输入表单，称之为金额，因此用户可以输入金额，然后将其传递给paypal。 Paypal网站称它并没有这样做。工作，但确实如此。

我使用的是低端Paypal标准，而不是任何更高级的接口。我有用户添加到购物车然后支付购物车。但你可以为立即购买按钮做同样的事情。使用哪种paypal服务并不重要。如果可以使用基本的PayPal标准，你可以用它们中的任何一个来完成......！

您还可以在交易后从paypal获得用户支付的各个方面。因此，有一个可用于总金额和个别金额的变量，等等。

这是设置捐赠金额以供用户输入的关键：

<input type="hidden" name="button_subtype" value="services">

当然：

     <b>Amount $:&nbsp;&nbsp; (Example:&nbsp; nnn.nn)</b>
  <input type="text" name="amount">

我不熟悉从paypal回来的变量。对于你想要的东西，贝宝标准应该从我所读过的内容中发挥作用。以下是两种方法，并且都使用paypal标准，因此可以使用任何paypal： 此链接包含以下两个，并提供简要概述： https://developer.paypal.com/webapps/developer/docs/classic/paypal-payments-standard/integration-guide/wp_standard_overview/

1） https://developer.paypal.com/webapps/developer/docs/classic/paypal-payments-standard/integration-guide/paymentdatatransfer/

2） https://developer.paypal.com/webapps/developer/docs/classic/ipn/integration-guide/IPNIntro/

这是表单的代码体。

    <form target="_blank" action="https://www.paypal.com/cgi-bin/webscr" method="post">
value="https://www.yourwebsite.com/logo.jpg"> -->
 <b>Amount $:&nbsp;&nbsp; (Example:&nbsp; nnn.nn)</b>
  <input type="text" name="amount">

 <input type="hidden" name="shipping" value="0.00">

  <input type="hidden" name="tax" value="0.00">

  <!-- Replace value with the web page you want the customer to return to -->

<input type="hidden" name="shopping_url" value="http://www.yours">

我建议使用paypal快速结账。这是一个简单的（PHP）示例：

// Parameters for SetExpressCheckout, which will be sent to PayPal

$padata['L_BILLINGAGREEMENTDESCRIPTION0']   = 'Product description';
$padata['L_BILLINGAGREEMENTDESCRIPTION0']   = $padata['L_BILLINGAGREEMENTDESCRIPTION0'] . 
' $'.$product->price.'/month';
$padata['L_PAYMENTREQUEST_0_DESC0']         = $padata['L_BILLINGAGREEMENTDESCRIPTION0'] . 
' $'.$product->price.'/month';
$padata['PAYMENTREQUEST_0_NOTIFYURL']        = 'http://site_url/paypal/ipn';
$padata['PAYMENTREQUEST_0_DESC']            = $product->name;
$padata['RETURNURL']                        = 'http://site_url/paypal/returnurl';
$padata['CANCELURL']                        = 'http://site_url/paypal/cancelurl';

$padata['PAYMENTREQUEST_0_CURRENCYCODE']    = 'USD';
$padata['PAYMENTREQUEST_0_PAYMENTACTION']   = 'SALE';
$padata['PAYMENTREQUEST_0_ITEMAMT'] = $product->price;
$padata['PAYMENTREQUEST_0_AMT']      = $product->price;
$padata['L_BILLINGTYPE0']            = 'RecurringPayments';
$padata['L_PAYMENTREQUEST_0_NAME0']  = $product->name;
$padata['L_PAYMENTREQUEST_0_NUMBER0']= '322';
$padata['L_PAYMENTREQUEST_0_QTY0']  = '1';
$padata['L_PAYMENTREQUEST_0_AMT0']   = $product->price;


$paypal_data            = http_build_query($padata);
$httpParsedResponseAr   = $this->PPHttpPost('SetExpressCheckout', $paypal_data);

//Respond according to message we receive from Paypal
if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])){

    //Redirect user to PayPal store with Token received.
    $paypalurl ='https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token='.$httpParsedResponseAr["TOKEN"].'';
    header('Location: '.$paypalurl);

}else{
    echo 'Error : '.urldecode($httpParsedResponseAr["L_LONGMESSAGE0"]).'';


}

Page returnurl：

$hosteddata['L_BILLINGAGREEMENTDESCRIPTION0']   = 'Recurring Description';
$hosteddata['L_BILLINGAGREEMENTDESCRIPTION0']    = $hosteddata['L_BILLINGAGREEMENTDESCRIPTION0'] . ' $'.$pr->price.'/month';
$hosteddata['L_PAYMENTREQUEST_0_NAME0']         = $pr->name;
$hosteddata['PROFILEREFERENCE']                    = $GetExpressCheckoutDetails['L_PAYMENTREQUEST_0_NUMBER0'];
$hosteddata['PROFILESTARTDATE']                 = date('Y-m-d') . 'T' . date('H:i:s').'Z';
$hosteddata['SUBSCRIBERNAME']                    = $GetExpressCheckoutDetails['FIRSTNAME'] . ' ' . $GetExpressCheckoutDetails['LASTNAME'];
$hosteddata['TOKEN']                          = urlencode($_POST['token']);
$hosteddata['DESC']                               = $hosteddata['L_BILLINGAGREEMENTDESCRIPTION0'];
$hosteddata['AMT']                             = $pr->price;
$hosteddata['BILLINGPERIOD']                  = 'Month';
$hosteddata['BILLINGFREQUENCY']                  = '1';
$hosteddata['TOTALBILLINGCYCLES']                = '12';
$hosteddata['REGULARTOTALBILLINGCYCLES']        = '1';
$hosteddata['VERSION']                           = '74.0';
$hosteddata['MAXFAILEDPAYMENTS']              = '1';
$hosteddata['L_PAYMENTREQUEST_0_QTY0']           = '1';
$hosteddata['L_BILLINGTYPE0']                    = 'RecurringPayments';
$hosteddata['L_PAYMENTREQUEST_0_ITEMCATEGORY0']  = 'Digital';
$hosteddata['L_PAYMENTREQUEST_0_AMT0']         = $pr->price;
$hosteddata['INITAMT']                            = $pr->price;
$hosteddata['L_PAYMENTREQUEST_0_NUMBER0']     = $pr->id;
$hosteddata['PAYMENTREQUEST_0_NOTIFYURL']        = 'http://site_url/paypal/ipn';


$paypal_data = http_build_query($hosteddata);
$hosted_saas_response = $this->PPHttpPost('CreateRecurringPaymentsProfile', $paypal_data);

我使用了一个单独的方法将参数发布到paypal 

private function PPHttpPost( $methodName_, $nvpStr_ ) {

$api_username   = 'yourpaypal@email.com';
$api_password   = 'QWEQWEWQEQWEQEQWE';
$api_signature   = 'WQEQWEQWEQWEWQEQWEQWEQWEQWEQWE.cT';
$api_endpoint    = "https://api-3t.paypal.com/nvp";
$version     = '124.0';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_endpoint);
   curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_POST, 1);
 
$nvpreq = "METHOD=$methodName_&VERSION=$version&PWD=$api_password&USER=$api_username&SIGNATURE=$api_signature&$nvpStr_";

curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);
$httpResponse = curl_exec($ch);

    if(!$httpResponse) {
        exit("$methodName_ failed: ".curl_error($ch).'('.curl_errno($ch).')');
}

    // Extract the response details.
    $httpResponseAr = explode("&", $httpResponse);

    $httpParsedResponseAr = array();
    foreach ($httpResponseAr as $i => $value) {
        $tmpAr = explode("=", $value);
        if(sizeof($tmpAr) > 1) {
            $httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1];
         }
    }

    if((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) {

        exit("Invalid HTTP Response for POST request($nvpreq) to $api_endpoint.");

    }

    return $httpParsedResponseAr;

}
